3D打印砂型铸造，传统铸造厂老板必看最先出现在三帝科技股份有限公司�?/p> ]]> In the traditional foundry industry, sand mold making has always been a key link affecting productivity, cost and molding capability of complex structure castings. With the increasing market demand for high-precision, short-delivery and complex structure castings, the traditional manual molding and mold manufacturing methods have been difficult to meet modern manufacturing requirements. Sand 3D printers, as an advanced additive manufacturing technology, can directly print complex sand molds and cores without the need for molds, dramatically shortening the production cycle, reducing costs, and enhancing design freedom. In this article, we will discuss why traditional foundries should consider introducing sand 3D printing technology to enhance competitiveness, optimize production processes, and meet market demand for efficient and accurate casting. The following is written exclusively for foundry owners, and we hope it will inspire you.

What is sand 3D printing?

Sand 3D printing is a relatively new technology, simply put, is like building blocks, with special materials layer by layer "pile" out of the casting sand.

In the past, the traditional method of making sand molds may need to make molds first, and then use the molds to shape, the process is more complicated, and if you want to make some sand molds with very strange and complex shapes, it will be particularly difficult and costly. But sand 3D printing is different, it works with a 3D model in your computer. You input the data of the 3D model of the designed casting into the 3D printer, and the printer will, according to the shape and structure of the model, put special sand or sand-like materials, according to the layer by layer in a precise way and bonded up, just like using countless thin "sand pieces" gradually built into a complete sand mold. In this way, no matter how complex the shape, as long as it can be designed in the computer, it can be printed out, and the speed is quite fast, and do not need to make complex molds like the traditional method, can save a lot of time and cost it.

spread sand: The printer spreads a specific casting sand (e.g. silica sand, ceramic sand or coated sand) evenly over the printing platform.

spray binder: The spray nozzles precisely spray the binder according to a computer model (CAD data) to bond the sand grains in a specific area.

pile up repeatedly: The platform is lowered, sand is spread again and the binder is sprayed, curing and molding layer by layer until the entire sand print is completed.

reprocess: Remove unbonded loose sand, harden and clean the printed sand model, which can then be used for metal casting.

• Manufacture of complex shaped partsTraditional sand casting to manufacture complex shapes is difficult and costly, such as aviation engine blades inside the fine cooling channels, traditional processes are difficult to accurately mold. 3D printing sand based on digital models, can easily turn complex shapes into reality, from the dense concave, raised automotive engine block sand, to have a subtle biomimetic structure of the shell of the medical device sand, can be perfectly rendered.
• long production lead timeTraditional sand casting need to go through a long process of designing molds, manufacturing molds, debugging molds, large-scale mold manufacturing cycle often exceeds a few months. 3D printing sand without mold production, directly according to the digital model printing, design modification is only required to operate the model on the computer, reprinting can be, can significantly shorten the production cycle. Such as research and development of new automotive engine block, the traditional casting mold scrap remake at least two weeks, 3D printing sand can be completed on the day of the new model printing, the next day can be put into casting.
• Difficulty in cost controlTraditional casting mold manufacturing material waste is serious, the utilization rate of complex mold materials is less than 30%, and high labor costs. 3D printing sand on-demand printing, accurate sand, material utilization rate of more than 90%, reduce waste. High degree of automation of the printing process can reduce labor costs. Take a small foundry as an example, with an annual production capacity of 5,000 pieces of small pipe fittings castings, after the introduction of 3D printed sand, the material cost will be reduced by 150,000 yuan per year, and the labor cost will be cut by 200,000 yuan.
• Low precision of castingsThe traditional sand mold due to mold wear, parting surface fitting error, casting size deviation often exceeds ±1mm, subsequent machining allowance, material waste, and prone to local loosening, sand entrapment and other defects, resulting in uneven mechanical properties of the casting. 3D printing of the sand model by the digital model of the precise drive, sand size accuracy of up to ±0.5mm, can achieve uniform compactness, to avoid uneven sand loose, and at the same time optimize the solidification process to significantly reduce shrinkage holes, shrinkage, to ensure reliable internal quality of the casting. At the same time, the solidification process is optimized, greatly reducing shrinkage holes and shrinkage loosening, and ensuring stable and reliable internal quality of castings.
• High environmental pressureTraditional casting mold manufacturing produces a large amount of waste metal, waste plastic, sand processing waste sand piles up. 3D printing sand production, unused sand can be recycled and reuse, very little waste, and the printing process does not require a large number of chemical binders, reducing the emission of hazardous gases, and improve the workshop environment. According to statistics, after the adoption of 3D printing sand mold, the casting workshop waste emissions reduced by more than 80%, dust, harmful gas concentration of environmental standards.

Product complexity: If the foundry often produces complex shapes, castings with fine structure or internal channels, such as aero-engine blades, automobile cylinder blocks, etc., the traditional process is difficult to meet the requirements, sand 3D printer can play an advantage.

Production size and lot size: For small-volume, multi-variety casting production, sand 3D printers offer the flexibility to quickly switch products without the need to make molds, reducing costs and cycle time. However, for large-scale, single-species castings, traditional processes may be more cost-effective.

Delivery period requirementsThe sand 3D printers allow for shorter lead times and quicker order response if the customer has stringent lead times.

cost-effectiveness

• Investment in equipmentThe cost of purchasing a sand 3D printer, installation and commissioning costs, and maintenance costs need to be taken into account.
• running cost: Includes printing materials, energy consumption, and labor costs. Compare with the traditional casting process and analyze the high and low long-term running costs.
• potential gainConsider the potential benefits of using sand 3D printers in terms of improved product quality, shorter cycle times, and lower scrap rates.

Employee Skills: Evaluate how well your current employees know 3D printing technology and whether you need to train or recruit specialized talent.

Technical Support: To understand the technical support capability of the equipment supplier, including whether the services such as installation and commissioning, training and fault repair are timely and effective.

market competition

• Industry Trends: Keep an eye on your peers to see if they are already adopting sand 3D printing, and if competitors are already using it and gaining an advantage, foundries may need to consider purchasing it in order to remain competitive.
• client needThe purchase of sand 3D printers can help to meet the needs of customers who want to see foundries adopting advanced technologies to improve product quality and productivity, as well as to increase their competitiveness in the marketplace.

environmental requirement

• If the local environmental protection requirements are strict, the traditional casting process is under great pressure in terms of waste sand treatment and exhaust gas emission, etc., sand 3D printers can help enterprises meet the environmental protection requirements due to the advantages of high material utilization rate and low waste.

探索无砂�?D打印�?/a>最先出现在三帝科技股份有限公司�?/p> ]]> This article explores sandbox-less 3D printers and how they can provide dimensional flexibility, high accuracy, cost-effectiveness, and design freedom from the limitations of traditional sandboxes to improve manufacturing efficiency. At the same time, it provides readers with an understanding of the innovative value and growth potential of sandbox-less 3D printers in the foundry sector.

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.

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.

This article focuses on SLS wax 3D printers, analyzing the key technical parameters of laser power and wavelength, layer thickness and accuracy, and temperature control of the build platform, and describing how they affect the printing results, wax quality, and suitability for different application scenarios, so that you can accurately assess the performance of the printer according to your own needs and make a more informed purchasing decision.

Sintering capacity correlationLaser power is a key parameter for SLS wax 3D printers and directly determines the effectiveness and efficiency of the wax sintering process. Higher laser power allows the wax particles to melt and bond together faster, making it possible to quickly build larger or thicker structures. For example, in the manufacture of wax molds for large industrial parts, sufficient laser power ensures that the wax powder is fully sintered in a short period of time, increasing the printing speed. However, if the laser power is too high, this may lead to overburning of the surface of the wax mold, e.g. scorching, deformation, etc., which affects the quality and subsequent use of the wax mold. On the other hand, too low a laser power may not allow the wax powder to melt completely, resulting in a weak sintering and a loose structure of the wax mold, or even damage during subsequent handling or processing.

Adaptation to different materials: Different types of wax materials have different requirements for laser power due to their different physical properties such as melting point and thermal conductivity. For wax powder with high melting point and relatively hard texture, higher laser power is often needed to realize good sintering; while wax powder with lower melting point and easier melting can use relatively low laser power. Therefore, the selection of wax powder materials needs to be considered in conjunction with the laser power range of the printer in order to achieve the best sintering results.

laser wavelength

• Material Absorption Properties: The wavelength of the laser also plays an important role in the printing process by influencing the degree of absorption of the laser energy by the wax material. Different wax materials have different absorption efficiencies at specific wavelengths. For example, some wax materials may absorb laser energy better at wavelengths in the near infrared (NIR) region, and under the irradiation of the laser at this wavelength, the laser energy can be efficiently converted into thermal energy, resulting in a good sintering. If the laser wavelength does not match the absorption characteristics of the wax powder material, even if the laser power is sufficient, it is difficult for the wax powder to fully absorb the energy for melting and sintering, which can lead to printing failure or poor quality of the printed wax model.
• Application Scenario Differences: In practical application, according to different use scenarios and requirements on wax mold performance, sometimes it is also necessary to choose a suitable wavelength of laser. For example, in the printing of jewelry wax molds, which requires high precision and high surface quality, a specific wavelength of laser may be selected, which can make the wax powder sintered finely and uniformly, and reduce the surface defects due to uneven energy absorption; while in some industrial wax molds manufacturing scenarios, which require lower precision and pay more attention to productivity, the laser may be selected according to the common wavelengths of the wax powder material, which are generally suitable for the wax powder to achieve fast and stable printing. realize fast and stable printing.

Impact on model refinement: The print layer thickness is the thickness of the wax mold layer that is formed when each layer of wax powder is sintered during the SLS printing process. Smaller layer thicknesses result in finer details and smoother surfaces. For example, when printing wax models of artistic sculptures with fine textures or intricate jewelry wax models, a layer thickness of a few tens of microns can clearly reproduce details such as tiny grain lines and thin-walled structures in the design model. On the contrary, a larger layer thickness can speed up the printing speed, but it will lead to obvious stepped textures on the surface of the wax model, reducing the fineness of the model, which is not suitable for some products with high demands on appearance and precision.

Trade-offs with print speed: There is often a trade-off between accuracy and speed when choosing a layer thickness for printing. Thinner layer thicknesses mean that more layers are needed to build the entire wax mold and print times increase significantly, while thicker layer thicknesses reduce the number of layers and speed up the process, but at the expense of some accuracy. In actual production, the layer thickness should be determined according to the specific product requirements and the urgency of the production task. For example, for mass-produced industrial molds that do not require particularly high precision, the layer thickness can be increased to improve production efficiency; while for customized, high-value fine wax molds, a smaller layer thickness is preferred to ensure quality.

Precision Analysis

• Dimensional accuracyDimensional accuracy is a function of how well the printed wax model matches the design model in terms of size, and is affected by a number of factors including the accuracy of the laser scanning system, the positioning accuracy of the mechanical moving parts, and the shrinkage of the wax powder material during the sintering process. High precision printers are able to control the dimensional error within a very small range, which is crucial for wax molds that need to be precisely matched with other parts, such as wax molds for precision casting and wax molds for dental restorations, or else the cast metal parts may not be able to be mounted properly or the medical restorations may not be effective.
• Shape AccuracyShape accuracy is related to the ability of the wax model to accurately reproduce the complex shapes and geometrical structures of the design model. Since SLS constructs wax molds by layer-by-layer sintering, it is easy to have accuracy problems in some parts with special shapes such as overhanging parts, thin walls, inner corners, etc. For example, the overhanging parts may need to be supported, and if the support design is not reasonable or not handled correctly after removing the support, the shape accuracy of the part may be affected. In addition, the planning of the laser scanning path and the uniformity of the wax powder will also affect the shape accuracy. Ensuring a good shape accuracy will ensure that the wax model meets the expected function and appearance requirements in the subsequent applications.

Wax powder spreading uniformityThe initial temperature of the construction platform has an important influence on the uniformity of the spreading of the wax powder on the platform. A suitable initial temperature enables the wax powder to spread better during the laying process and avoids localized piles or vacancies. For example, when the platform temperature is slightly higher than the fluidity temperature of the wax powder at room temperature, the wax powder can be evenly spread on the platform like fine sand, providing a good starting condition for subsequent laser sintering. If the platform temperature is too low, the wax powder may not be able to spread out smoothly, resulting in uneven thickness of each layer of wax powder, which in turn affects the quality of the whole wax mold; whereas too high a platform temperature may cause the wax powder to be partially melted and sticking before it is spread out, which likewise destroys the molding effect of the wax mold.

Quality of the first sintered layer: The initial temperature also affects the sintering quality of the first wax mold layer. A suitable platform temperature helps the wax powder to bond better with the platform under laser irradiation and improves the firmness of the first layer, so that it can provide a stable foundation for the construction of subsequent layers. Different wax materials have different optimal initial platform temperatures, which need to be set accurately according to the properties of the wax powder used to ensure a good sintering of the first layer and to prevent separation of the first layer from the platform or incomplete sintering.

temperature stability

• Printing Process Impact: The temperature stability of the build platform is crucial during the whole wax mold printing process. Large fluctuations in temperature can lead to changes in the physical properties of the wax powder (e.g. fluidity, sintering characteristics, etc.), which in turn affects the bonding effect between the layers of the wax mold and the structural stability of the overall wax mold. For example, a sudden increase in temperature may cause excessive melting of the wax powder being sintered, destroying the structure of the existing wax mold; a decrease in temperature may cause insufficient sintering of the subsequent wax powder, resulting in quality problems such as delamination and cracking. Therefore, printers are usually equipped with a high precision temperature control system that monitors and regulates the platform temperature in real time to keep it within a set stable range, ensuring high quality sintering from the first to the last layer of the wax mold.
• Requirements for different wax mold typesThe requirements for temperature stability of the platform vary for different types and sizes of wax molds. For large, thick-walled wax molds, due to the longer printing time, the cumulative effect of temperature changes is greater, and stricter temperature control is needed to ensure uniform sintering of the internal and external wax structure; while small, thin-walled wax molds, although the printing time is relatively shorter, due to the fragility of their structure, they are more sensitive to temperature fluctuations, and they also need a stable platform temperature environment to ensure the quality of wax molds to avoid deformation, damage, etc. caused by temperature changes. The temperature environment should be stabilized to ensure the quality and to avoid the deformation and damage of the wax molds due to temperature change.

In summary, the key technical parameters of laser power and wavelength, print layer thickness and accuracy, and temperature control of the build platform interact with each other to determine the print performance and mold quality of SLS wax 3D printers, and require in-depth understanding and consideration when using and evaluating these printers.
