1. 解決傳統(tǒng)鑄造工藝的限制

復(fù)雜結(jié)構(gòu)成型難 

傳統(tǒng)鑄造工藝在制造復(fù)雜形狀的砂型模具時，往往面臨巨大的技術(shù)難題和高昂的成本。例如，航空發(fā)動機葉片內(nèi)部通常有精細復(fù)雜的冷卻通道，傳統(tǒng)工藝制造這類模具的難度極高。而砂型3D打印機通過數(shù)字化建模和逐層打印技術(shù)，能夠輕松實現(xiàn)復(fù)雜形狀砂型的制造，極大地降低了技術(shù)門檻和成本。

定制化生產(chǎn)受限 

隨著個性化消費和小眾市場的興起，小批量、定制化鑄件的需求呈爆發(fā)式增長。然而，傳統(tǒng)鑄造工藝的開模成本高、定制周期長，難以滿足市場的快速響應(yīng)需求。砂型3D打印機無需模具，能夠根據(jù)客戶的特殊規(guī)格、造型和性能要求，快速設(shè)計并打印砂型，極大地提高了定制化生產(chǎn)的靈活性和效率。

2. 提升生產(chǎn)效率與成本控制

砂型3D打印機解決了什么核心問題？這篇文章告訴你真相最先出現(xiàn)在三帝科技股份有限公司。

Why is it called a sandbox-less 3D printer?

The boxless 3D printer is so named because it eliminates the use of a traditional box in the sand 3D printing process, significantly differentiating it from conventional sand 3D printers. Here's more about it from a variety of perspectives:

The role and limitations of traditional sandboxesSandboxes are an indispensable part of the traditional sand casting process and some traditional sand 3D printing techniques. It is used to hold the sand, provide molding space for the sand model, ensure that the sand maintains a specific shape during the molding process, and ensure the integrity of the sand model during transportation and box closing. However, the fixed size of the sand box limits the size of the sand mold that can be produced, and the production and maintenance costs are high. For the complex structure of the sand mold, the sand box is difficult to design and manufacture, and it may also affect the heat dissipation and air permeability of the sand mold, which may affect the quality of the castings.

How sandless box 3D printers work: The sandbox-less 3D printer adopts sandbox-less flexible area molding technology, in which abrasive and binder are stacked and molded layer by layer by the nozzle directly on the worktable. The equipment has a precise sand spreading system, which can evenly spread the sand material in the printing area, and the nozzle accurately sprays the binder according to the model cross-section information, so that the sand particles are bonded to form the sand shape layer by layer. In this process, there is no need for a sand box to provide molding space and constraints, which greatly improves printing flexibility and freedom.

Basis of namingThe naming of the 3D printer directly reflects its core technical feature, which is that it is free from the constraints of the traditional sand box, creating a new mode of sand 3D printing. This naming scheme is simple and clear, highlighting the essential difference with the traditional sand 3D printing equipment, and emphasizing its unique advantage of realizing high-precision and high-efficiency manufacturing of sand patterns without the assistance of a sand box during the printing process.

Sandless Box 3D Printer vs. Traditional Sand 3D Printer

There is a clear difference between the working principle of a boxless 3D printer and that of a traditional sand 3D printer. Traditional sand 3D printers rely on a fixed sand box to define the molding space, and rely on the sand box to provide partial support, and the print path is limited by the sand box; while sand box 3D printers use flexible area molding technology, expanding the printing platform on demand, breaking through the size limitations, and supplying the sand and binder with greater precision, and adjusting the internal sand buildup and binder injection to provide support, so the print path is more freely and flexibly planned, and it can effectively improve the printing efficiency and sand quality. It can effectively improve the printing efficiency and the quality of the sand mold.

Prospects for sandbox-less 3D printers in the foundry sector

The development of sandbox-free 3D printers in the foundry field is very promising, mainly in the following aspects:

Technological innovation and breakthroughs

Sandbox-free 3D printers continue to realize technological innovations, such as SANDI's 3DPTEK-J4000 Adoption of sandbox-less flexible area molding technology, can be customized to expand the printing platform, the maximum molding 4 meters of sand, to meet the production needs of 10 meters + level, breaking through the traditional casting equipment size limitations, for the manufacture of large and complex castings to provide the possibility of.

Significant cost advantages

On the one hand, the cost of ownership is reduced, as the price of 4-meter and larger boxless 3D printers is comparable to that of 2.5-meter machines, allowing companies to obtain larger sizes of abrasive molds at a lower cost per unit. On the other hand, material waste is reduced, as boxless 3D printers allow precise use of materials such as sand and binder, reducing production costs.

Strong growth in market demand

Aerospace, automotive, energy power and other fields of large, complex, high-precision castings demand continues to rise. For example, the manufacture of aircraft engine components, automotive engine block, etc., sandless 3D printers can meet the high-performance requirements for castings in these fields, the market potential is huge.

Significant increase in design freedom

The sandless box 3D printer can manufacture complex geometric shapes and cavities that are difficult to achieve by traditional methods, realizing parts integration and lightweight design, providing more space for product innovation and helping to improve product performance, reduce costs and enhance the market competitiveness of enterprises.

Significant increase in productivity

Compared to traditional mold making methods, sandbox-less 3D printing of sand molds or cores takes only a few hours to a few days, dramatically shortening the development and production cycle of new products, helping manufacturers respond faster to changes in market demand, and improving productivity and economic efficiency.

Superior environmental performance

Sandless 3D printers use materials on demand, reducing waste and disposal costs of leftover materials, and some of the equipment can use environmentally friendly materials and binders, which reduces environmental pollution, meets the requirements of sustainable development, and helps foundry companies to meet the increasingly stringent restrictions of environmental regulations.

Deepening Industrial Integration

The integration of sand box 3D printer and foundry is deepening, enterprises through mergers and acquisitions of foundries and other ways to open up the "3D printing + casting" process, to provide the whole industry chain overall solution, and promote the foundry industry to the green, intelligent, high-end direction of development.

I. High-precision and complex structure manufacturing capability

Sand mold 3D printers are able to create sand molds with extreme precision, which is essential for producing high-quality castings. While traditional methods of sand mold making are often overwhelmed by the complexity of the structures, 3D printing makes it easy. It is able to accurately reproduce every detail of a design drawing, whether it is a complex internal cavity, a fine texture or a thin-walled structure. This high-precision manufacturing capability not only improves the dimensional accuracy and surface quality of the castings, but also reduces subsequent machining processes and production costs. For example, in the aerospace field, some key components require extremely high precision, and sand mold 3D printers can produce sand molds that meet strict standards, thus ensuring the quality and performance of the final casting, and meeting the demanding requirements of aerospace products for safety and reliability.

II. Shortening the production cycle

The traditional sand mold production process is usually more cumbersome, need to go through the mold design, production, assembly and other aspects, consuming a lot of time. Sand mold 3D printer greatly simplifies this process, it can be directly based on the digital model of the sand mold layer by layer printing, without the need to make molds and complex assembly operations. This shortens the production cycle significantly, enabling companies to bring products to market faster and seize the first opportunity. Taking automobile manufacturing as an example, the development cycle of new models is often very tight, sand mold 3D printer can make sand molds for automobile engines and other parts in a short period of time, accelerating the trial production process, helping enterprises to verify and optimize their products faster, and improving the overall research and development and production efficiency.

III. Cost reduction

The purchase of a sand mold 3D printer requires a certain initial investment, but in the long run, it can bring significant cost reductions for enterprises. On the one hand, as mentioned earlier, it reduces the mold making and assembly in the traditional sand mold making process, reducing labor costs and mold costs. On the other hand, as 3D printing can realize high-precision manufacturing, it reduces the scrap rate and subsequent processing costs. In addition, 3D printing technology can also optimize the design of the sand mold, so that it meets the requirements of the premise of more lightweight, thus reducing the use of casting materials, further reducing costs. For some small batch but a variety of products for the enterprise, sand mold 3D printer cost advantage is more obvious, because it does not need to make a special mold for each product, greatly reducing the production cost and inventory pressure.

IV. High degree of design freedom

Sand mold 3D printers offer designers a high degree of design freedom. Traditional manufacturing processes are often limited by the structure of the mold and the manufacturing method, and designers need to consider many process factors when designing a product, thus compromising the design. 3D printing technology, on the other hand, breaks down these limitations and allows designers to give full play to their imagination and design more innovative and unique product structures. For example, they can design castings with complex internal runners to optimize product performance, such as improving heat dissipation efficiency or fluid flow performance. This increased design freedom not only helps companies develop more competitive products, but also promotes innovation in the industry as a whole.

V. Personalization

With the diversification of market demand and the trend of individualization becoming more and more obvious, personalized customization has become an important development direction of the manufacturing industry. Sand mold 3D printer can precisely meet this demand, it can according to the customer's specific requirements, quickly create a unique sand mold, to achieve personalized custom production. Whether it is a single piece of customization or small batch customization, sand mold 3D printer can easily deal with. This is important for some high-end equipment manufacturing, medical equipment and other fields.

VI. Environmental protection and sustainable development

In today's era of environmental protection and sustainable development, sand mold 3D printers also have certain advantages. The traditional sand mold production process will produce a large number of waste and pollutants, such as waste mold materials, chemical reagents, etc., causing greater pressure on the environment. The sand mold 3D printer in the manufacturing process is relatively more environmentally friendly, it is mainly used in sand and other environmentally friendly materials, and can be optimized through the design and printing parameters to reduce the waste of materials. In addition, because 3D printing technology can achieve precision manufacturing, reducing the production of scrap, further reducing the impact on the environment. Therefore, the purchase of sand mold 3D printers is in line with the company's environmental philosophy and social responsibility, and helps the company achieve sustainable development.

To sum up, purchasing sand mold 3D printer has many advantages, including high precision and complex structure manufacturing ability, shorten the production cycle, reduce costs, high design freedom, personalized customization and environmental sustainability. For modern manufacturing enterprises, sand mold 3D printer is not only a kind of advanced production equipment, but also an important tool to enhance the competitiveness of enterprises and realize innovative development and sustainable development.

I. Understanding your own needs

Analyzing the current situation of factory production

• Evaluation of traditional process: Carefully review the traditional casting process currently used in the factory, including the way the molds are made (e.g., wood molds, metal molds, etc.), the molding process (hand molding or machine molding), and the process of melting and pouring. Evaluate the time, labor, and material costs as well as the problems associated with each process. For example, traditional wooden mold making can take weeks and is prone to dimensional deviations and damage; hand molding is labor-intensive, inefficient and inconsistent in quality.
  • Product Characterization: Define the type of castings that the plant will mainly produce, whether they are castings with simple structures or castings with complex internal cavities, thin-walled structures or finely curved surfaces. Determine the size range of the castings, from small castings of a few centimeters to large castings of several meters. At the same time, analyze the requirements for casting accuracy, for example, certain aerospace castings may need to be millimetre accurate or even higher. In addition, the material of the casting should be considered, which may vary from material to material in terms of casting process and equipment requirements.
  • Production scale considerations: Evaluate the daily production scale of the plant, including monthly or annual casting production. Understand the characteristics of the production orders, whether it is a large number of single product production or small quantities of multi-species production. For the peak and trough production capacity changes also need to have a clear understanding, which will affect the selection of equipment and production arrangements.

Defining goals and desired improvements

• Cost control objective: If cost reduction is the main objective, the cost composition of each link needs to be analyzed. Mold production costs account for a large proportion of the traditional process, and sand 3D printers can eliminate the mold production process, significantly reducing this part of the cost. At the same time, considering labor costs, 3D printers have a high degree of automation, which can reduce the reliance on labor. In terms of material costs, although 3D printing requires specific sand and binder, material utilization can be improved by precisely controlling the amount of material used, and waste can also be reduced through the re-cycling of sand. In addition, the 3D printing process can optimize the structure of sand molds and reduce the amount of sand used through lightweight design. For example, for a medium-sized foundry, by introducing sand 3D printers, the cost of molds may be reduced by 40%, the labor cost by 30%, and the material cost savings by about 20%.
  • Efficiency Improvement Requirement: For foundries pursuing productivity improvement, focus on the molding speed of the equipment. Sand 3D printers can print a complex sand pattern in a few hours, compared with the traditional mold making and molding weeks, a significant increase in efficiency. In addition, 3D printers can print multiple sand molds at the same time, or zone printing on a large sand mold, greatly reducing the overall production cycle. For example, after the introduction of 3D printers in an automotive parts foundry, the product development cycle has been shortened from several months to a few weeks, and production efficiency has been increased by more than 50%.
  • Quality Improvement Expectations: The ability of sand 3D printers to print with high precision is critical when higher quality products are required. It can precisely control the size and shape of the sand mold, reducing dimensional deviations and surface defects in the castings. At the same time, due to the stability and consistency of the printing process, it can improve the internal quality of castings and reduce defects such as porosity and slag entrapment. For example, in some high-end equipment manufacturing fields, the scrap rate of 3D printed sand castings has been reduced from 10% in the traditional process to less than 2%, and the product quality has been greatly improved.
  • Flexibility enhancement direction: for foundries that need to respond to small batch, multi-variety production needs or personalized custom orders, the advantages of sand 3D printer is particularly obvious. It does not need to make physical molds, can be quickly switched to produce different products according to the digital model, greatly improving the flexibility of production. For example, some art foundries or customized parts production enterprises, through the 3D printing technology can meet the diverse needs of customers, broadening the market space.

Evaluation of key features of sand 3D printers

Printing Accuracy

• Impact of precision on casting quality: Printing precision directly determines the dimensional accuracy and surface quality of castings. High-precision printing can ensure that the dimensional deviation of the castings is within a very small range and meet the strict assembly requirements. In terms of surface quality, high-precision printing can reduce the roughness and defects on the surface of the casting and improve the appearance quality of the casting. For example, in the production of key components such as engine blocks, high-precision sand molding can ensure the precision of the fit between the piston and the cylinder block and improve the performance and reliability of the engine.
  • Choosing the right precision equipment: First, the required precision level is determined according to the design requirements and usage scenarios of the product. For some common mechanical parts, millimeter-level accuracy may be sufficient; while for high-precision castings in aerospace, medical devices and other fields, sub-millimeter or even higher accuracy may be required. Secondly, understand the precision parameters of different devices, including layer thickness and dimensional error range. You can refer to the technical information and actual test data provided by the manufacturer, while exchanging experiences with other users. For example, 3DPTEK sand 3D printers are capable of achieving a dimensional accuracy of ±0.3mm, which is suitable for the production of castings with high accuracy requirements.
  • Comparison of different precision level equipment and applicable scenarios: low-precision equipment is usually relatively low-priced, applicable to some production scenarios that do not require high precision and focus on cost control, such as ordinary construction machinery castings. Medium-precision equipment balances price and performance, and is suitable for the production of most industrial parts. High-precision equipment, on the other hand, is suitable for high-end manufacturing areas, such as aerospace, precision instruments, etc., but the price is relatively high. For example, in the production of automobile engine cylinder head, medium-precision equipment can meet the basic production requirements; for aero-engine blades and other high-precision castings, you need to choose high-precision equipment.

Print Size

• Print size in relation to production scale and casting size: For large foundries, equipment capable of printing large castings is often required to meet production demands. For example, in the production of large ship engine block, may require several meters or even larger size printing equipment. For small foundries or production of small castings of enterprises, the smaller size of the equipment may be more economical and practical. At the same time, the print size also affects the footprint and space requirements of the equipment, which need to be taken into account in factory planning.
  • Selection strategy: according to the factory's production planning and market positioning to determine the required print size. If the main production of large castings, you need to choose a larger print size of the equipment; if the main small castings, you can choose small or medium-sized equipment. Also consider the future development needs, set aside a certain amount of capacity expansion space. In addition, pay attention to whether the equipment print size can be flexibly adjusted, for example, some equipment can be replaced by the printing platform, or even no sand box printing to adapt to the production of castings of different sizes. For example, a medium-sized foundry plans to expand into the field of large-scale casting production in the future, then in the selection of equipment, you can give priority to those with upgradable print size or modular design of the equipment in order to expand in the future according to demand.

Equipment stability and reliability

• The importance of stable operation of equipment: in casting production, the stability of equipment is crucial. Once the equipment failure, it may lead to production interruption, affecting the delivery date, and bring great economic losses to the enterprise. Especially for the continuous production of foundry, equipment for a long time stable operation is to ensure production efficiency and product quality basis. For example, in the automotive parts casting production line, if the 3D printer frequently fails, it will lead to production line stagnation, affecting the whole car production schedule.
  • Examine methods of stability and reliability:
    • Check the manufacturer's quality control system: understand the manufacturer's production quality management process, including raw material procurement, parts processing, assembly and commissioning and other aspects of quality control measures. A manufacturer with a perfect quality control system is usually able to produce more stable and reliable quality equipment. For example, some well-known manufacturers of each component are strictly quality testing to ensure that it meets the high standards of quality requirements.
    • User Word of Mouth: Communicate with users who have already used the device to understand their evaluation of the stability and reliability of the device. The actual use experience of users is the most direct and real feedback. You can participate in industry exhibitions, join professional communities and other ways to establish contact with other users to get their opinions and suggestions. For example, some foundries will prioritize those brands with good reputation in the same industry when choosing equipment.

Software Support

• Excellent software features and functions:
  • Model Processing: Powerful 3D printing software can efficiently process complex casting models, including model repair, optimization, slicing and other functions. For example, for some models imported from CAD software that may be defective or unsuitable for printing, the software can automatically detect and repair these defects to ensure that the model can be printed smoothly.
  • Printing parameter setting: The software should provide a wealth of printing parameter setting options, such as printing speed, layer thickness, nozzle temperature, binder dosage and so on. Users can according to different casting requirements and material properties, precise adjustment of these parameters to obtain the best printing results. For example, for thin-walled castings, it may be necessary to adjust the layer thickness and printing speed to ensure the strength and precision of the sand mold.
  • Production process management: the software should also have production process management functions, including order management, task scheduling, equipment monitoring. This can help foundries realize efficient production management and improve production efficiency. For example, through the software can real-time monitoring of the operating status of the equipment and printing progress, rationalize the arrangement of production tasks to avoid production congestion.
  • Evaluate software for ease of use, functional integrity, and compatibility with devices:
    • Ease of use: the operating interface of the software should be simple and clear, easy to get started. With an intuitive graphical interface and clear operating procedures, even non-professional technicians can quickly master. Ease of use can be assessed by trying out the software or viewing a demo video of the software in action. For example, some software adopts a wizard-type operation process, users only need to follow the prompts step-by-step operation to complete the entire printing process.
    • Functional completeness: Check whether the software has the basic functions mentioned above such as model processing, printing parameter setting, production process management, and whether there are some special features such as automatic optimization algorithms, remote control and so on. The more complete the function, the higher the applicability and flexibility of the equipment. For example, some software has intelligent optimization algorithms, which can automatically adjust the printing parameters according to the shape and structure of the casting to improve printing efficiency and quality.
    • Compatibility: Ensure that the software has good compatibility with the device and can drive the device stably for printing. Also consider the compatibility of the software with other design software, such as CAD software, for smooth model import and processing. You can check the software's technical documentation or consult with the manufacturer to find out what file formats and software interfaces it supports. For example, some software supports common file formats such as STL, OBJ, etc., and can work seamlessly with most CAD software.

III. Cost and return on investment analysis

Equipment purchase costs

• Price range for different brands and configurations: The price of sand 3D printers varies depending on the brand, technology level, print size, accuracy and other factors. Generally speaking, the price of equipment from European and American brands is relatively high, and may be in the millions or even tens of millions of dollars; the price of equipment from Chinese brands is relatively low, and may range from hundreds of thousands of dollars to millions of dollars depending on different configurations. For example, some high-end European and American equipment with advanced technology and excellent performance, but the price is very expensive; and some of China's emerging brands of equipment in the price-performance ratio is more advantageous, such as 3DPTEK, this brand is more famous in China, the equipment is very cost-effective, while 3DPTEK operates its own almost 10 foundries, but also dozens of foundry enterprises in China to provide Equipment, it can be said that the market has been strictly verified, is a very good choice.
  • Analysis of the reasons for price differences:
    • Technology level: Advanced printing technology, high-precision control system, stable mechanical structure, etc. will increase the cost of the equipment. For example, equipment using laser sintering technology is usually more expensive than equipment using ordinary binder jetting technology, because laser sintering technology offers higher precision and better sand strength.
    • Brand influence: well-known brands usually invest more in research and development, production, after-sales service, etc., and their brand value will also be reflected in the price of equipment. Some brands with many years of industry experience and good reputation, often able to provide more reliable equipment and better service, but the price is also relatively high.
    • After-sales service: perfect after-sales service system, including equipment installation and commissioning, training, maintenance, technical support, etc., will increase the manufacturer's operating costs, which is reflected in the price of equipment. Some manufacturers provide 24-hour online technical support, rapid response maintenance services, etc., which will have an impact on the price.

operating cost

• Cost of supplies:
  • Sand: Sand used in sand 3D printers typically needs to meet certain grain size, shape, and strength requirements. Prices for different qualities of sand vary and fluctuate with market supply and demand. For example, some high-strength, low-dust specialty sands may be relatively expensive, but can improve the quality of the sand pattern and printing results.
  • Binder: Binder is the key material to bond the sand together to form the sand mold, and its price will also affect the operating cost. Different types of binder differ in performance and price, and need to be selected according to actual needs. At the same time, the amount of binder will also affect the cost, some advanced printing technology can reduce the amount of binder used to reduce costs.
  • Energy consumption cost: the equipment will consume electricity during operation, and its energy consumption cost is related to the power of the equipment, running time, electricity price and other factors. When choosing equipment, you can focus on the energy efficiency ratio of the equipment and choose energy-saving equipment. For example, some devices use advanced energy-saving technologies that can reduce energy consumption under the premise of ensuring print quality. High-power devices usually consume more energy per unit of time, and if the device runs continuously for a long time, the cost of energy consumption will increase significantly. And the difference in electricity prices in different regions will also have an impact on the cost, such as industrial power consumption in concentrated areas may have certain preferential policies on electricity prices, need to take these factors into account to accurately assess the cost of energy.
  • Equipment Maintenance Costs: Regular maintenance and upkeep of equipment is necessary to ensure its normal operation and incurs certain costs. Including the replacement of wearing parts, equipment cleaning, calibration and other aspects of the cost. Some manufacturers will provide equipment maintenance service packages, foundries can choose according to their own situation. At the same time, the reliability and stability of the equipment will also affect the maintenance costs, low failure rate of the equipment maintenance costs are relatively low. For example, some equipment using high-quality components and advanced design, reducing the frequency of replacement of wear parts, reducing maintenance costs.

Return on investment assessment

• Cost savings analysis:
  • Mold Cost Savings: As mentioned earlier, the cost of making molds in a traditional casting process is high, whereas sand 3D printers eliminate the need to make physical molds, which can significantly reduce this cost. Mold cost savings can be assessed by calculating the difference between the cost of making a traditional mold and the cost of 3D printing a sand mold. For example, a complex casting can cost tens of thousands of dollars to make the mold, whereas with a 3D printed sand pattern, this cost can be reduced by more than 80%.
  • Labor Cost Savings: Due to the high degree of automation in 3D printers, the reliance on labor is reduced. Labor cost savings can be calculated by comparing the amount and cost of labor in a traditional process to the labor requirements with the adoption of 3D printing. For example, a traditional casting line may require dozens of workers for mold making, molding, etc., whereas with the adoption of 3D printers, only a few operators may be needed for equipment monitoring and maintenance, and labor costs can be reduced by about 50%.
  • Material Cost Savings: Material costs can be reduced by accurately controlling the amount of material used and improving material utilization. For example, while traditional molding processes may produce large amounts of waste sand and scrap, 3D printing can reduce waste by accurately controlling material usage based on the model. At the same time, some 3D printed materials can be recycled, further reducing costs.
  • Increased revenue from efficiency gains:
    • Reduced cycle time: Sand 3D printers can significantly reduce product development and production cycles. For some products that need to be on the market urgently, early delivery can result in a higher market price and competitive advantage. The value of the efficiency gains can be assessed by calculating the additional benefits of delivering products earlier. For example, by adopting 3D printing technology, an automotive parts foundry shortened the development cycle of new products from 6 months to 2 months, and entered the market ahead of schedule, gaining a higher market share and sales revenue.
    • Increased capacity: Efficient operation of the equipment and rapid prototyping capabilities can increase the capacity of the plant, thereby increasing sales revenues. The increased capacity and corresponding sales revenue can be projected based on the plant's production schedule and market demand. For example, if a foundry was producing 1,000 castings per month and the introduction of 3D printers increased capacity to 1,500 castings, and assuming a profit of $100 per casting, the increase in profit would be $50,000 per month.
  • Calculation of the payback cycle: The feasibility of the investment is assessed by calculating the payback cycle, taking into account factors such as equipment purchase costs, operating costs, cost savings and increased revenue. The payback cycle refers to the time it takes from the time the equipment is put into use to the time it takes to recover the full investment. For example, assuming that the purchase cost of a sand 3D printer is $2 million, and that cost savings and increased revenue total $800,000 per year, the payback cycle will be about 2.5 years. The potential impact of market changes, technology updates, and other factors on the payback cycle also needs to be considered in order to make a more accurate assessment.
