A 3D printer for casting is a modeling method that imports 3D data created using CAD and directly shapes sand molds (such as cores and main molds). It is often referred to as a mold 3D printer or core molding machine, and it can shorten the lead time for producing wooden or resin molds needed for complex shapes, as well as for sand preparation and mold assembly before casting. Rather than relying solely on 3D printers, we recommend a hybrid operation that leverages the advantages of existing methods, the benefits of 3D printing, and your company's strengths and weaknesses. **Features of Utilizing 3D Data and 3D Printers:** - It is possible to create casting 3D data by 3D scanning the product shape even without wooden molds. - For complex-shaped cores, many wooden molds are unnecessary, leading to reduced manufacturing lead times, lower management and storage costs, and shortened assembly time and labor for cores. - Since 3D data is output, there is less variation, and the imbalance in cast products is also reduced. - 3D data can be used not only for modeling but also for verifying products against drawings. - 3D data can also be utilized for casting simulations and other applications. Why not try using a 3D printer this year? We will support you from data creation onwards.

• 3D Printer

The "SCM Series" is a 3D printer for casting that produces "casting molds" and "cores" using sand molds. It utilizes a 3D printer for casting that employs an inkjet method with "dry artificial sand." By discharging resin into dry artificial sand (produced by GunEi Chemical Industry) and curing it, it enables the high-precision production of complex-shaped cores and molds. - The production time for casting prototypes can be significantly reduced. Since model production is unnecessary, the time required for prototype production, which previously took about a month, can be greatly shortened. - It is possible to reduce model production costs. Direct sand mold production from 3D (CAD/scanner) data eliminates the need for model production and storage space for wooden molds. If shape changes are necessary, production can be done immediately after data modification. - The simultaneous production of various similar items with different shapes and dimensions reduces lead time in the prototyping stage. It is possible to simultaneously produce items with different shapes that require verification of shapes and dimensions, such as aggressive method models. 【Features】 ■ Total support for equipment, materials, and software ■ Sales track record to casting manufacturers and casting prototype manufacturers ■ Development achievements for high-value-added products from aluminum to stainless steel ■ Reduction of troublesome sand removal work due to dry materials ■ Reuse of uncured sand (recovered sand) is possible ■ Material development tailored to user needs

Since the release of the transparent resin series, we have significantly improved the heat resistance temperature, which was highly demanded by users. Not only does the heat resistance exceed 100°C after heat treatment, but the yellowing of the resin during heat treatment has also been greatly reduced.

• 3D Printer

Since the launch of the transparent resin series, not only has the previously high demand for improvement in yellowness been reduced, but the toughness, which had high functional requirements, has also been significantly enhanced. Additionally, environmental considerations have been taken into account, and no antimony compounds, which are toxic and hazardous substances, have been used.

During temporary extracorporeal circulation in surgery, it serves the role of human lungs. It primarily performs gas exchange, adding O2 to the blood and removing CO2. O2 is flowed through hollow fiber membranes packed inside the artificial lung, while blood flows around it to facilitate gas exchange across the membrane. Utilizing photopolymerized products, fluid analysis (CFD) is conducted to examine the optimal blood flow within the artificial lung. A mechanism is created on the inlet side to form blood spots and on the outlet side to gather them at a single point to prevent pressure loss.

In the latest resins, significant improvements have been made regarding the negative perception of photopolymer resins related to humidity-induced "deformation and dimensional changes." The moisture resistance values are now less than half of those of conventional resins. Considering that photopolymer products are expected to be used directly in evaluation tests that take several weeks, rather than just for simple shape confirmation or as a master for casting that is completed in a few days, this performance is absolutely necessary. 【Applications】 - Shape confirmation - Visualization model for cooling channel evaluation ● For more details, please download the catalog or contact us.

Until now, the issue with light-curing resins was that when heat treatment was applied to improve heat resistance, the color of the model changed to a brownish hue, significantly worsening visibility. The transparent heat-resistant resin "TSR-884B" maintains its transparency even after heat treatment, ensuring that visibility is not compromised. The newly released TSR-884B addresses this issue, and as can be seen in photographs, the yellow index and total light transmittance show almost no change even after heat treatment. This also means that visibility is less likely to decrease during heat resistance testing. 【Applications】 - Design verification - Assembly verification of various parts, wiring verification - Lighting evaluation testing ● For more details, please download the catalog or contact us.
