Notice of Participation in the Japan International Machine Tool Fair (JIMTOF2022)

One of the largest in Kanto! If you are planning to introduce a 3D printer, please be sure to visit us!

In November 2021, we opened a showroom for 3D printers at the Hotti Polymer factory in Kuki, Saitama. Focusing on the MEX method, it is possible to view various types of 3D printers, including photopolymerization and LAM (liquid additive manufacturing) methods, as well as models from different manufacturers within the same method all at once. Additionally, you can also see our in-house printer "Silicom," which can create 100% silicone rubber, a rarity even on a global scale. We invite you to visit us. 【Exhibited 3D Printers】 ■ MEX (resin extrusion additive manufacturing) 3D printer ■ Photopolymerization LCD method (transmissive liquid crystal method) 3D printer ■ Photopolymerization SLA method (laser method) 3D printer ■ LAM (liquid additive manufacturing) 3D printer ■ Poly Jet (inkjet) method 3D printer * New models will be added as they become available. * For more details, please refer to the PDF document or feel free to contact us.

Expanding the possibilities of 3D printers! Engineering software with various features.

nTopology is software that integrates with existing CAD/CAM systems to realize engineering flows that include topology optimization and more. In recent years, with the advancement of 3D printing, there has been a demand for designs that leverage the high degree of freedom in manufacturing characteristics compared to traditional processing methods, known as DfAM (Design for Additive Manufacturing). This product allows for the incorporation of functional shapes derived from existing CAD systems and enables output to various formats using parameters defined by tools such as Excel.

Achieve lower costs than cutting processes! The production of three-dimensional products using PEEK (polyether ether ketone) is realized with a 3D printer!

In the production of three-dimensional products using PEEK (polyether ether ketone), injection molding is mainstream for large lots, while machining is the norm for small lots. For three-dimensional products made of PEEK, we have started contract processing using FDM (Fused Deposition Modeling) 3D printers with PEEK filaments produced by our company. This significantly reduces waste and allows for cost reduction. Additionally, with 3D printing, it is possible to create hollow or honeycomb structures internally, enabling material cost reduction and weight savings compared to machining, which can only produce solid forms. 【Features】 ■ Weight reduction: It is possible to achieve weight savings by creating hollow or honeycomb structures! ■ Cost-effectiveness: There is no material waste from machining, making it economically advantageous! ■ Precision: Production is possible at the intermediate level of JISB0405! (Consultation required) ■ Advancement: Due to the FDM method, it is possible to create shapes that cannot be accommodated by machining! *Please inquire as there may be limitations based on the shape. *If we are unable to produce after receiving an order, we will not charge for the costs incurred. For more details, please download the catalog or contact us directly.

Proposal for problem-solving with the introduction of 3D printers! Introducing examples of cost reduction in mass production.

Our company has introduced 3D printers and primarily offers products related to extrusion molding from design to mass production. We received a request for airtight pieces for building components. Due to the small lot size, it was difficult to amortize the investment in molds, so we proposed a method of creating a simple mold using polylactic acid, filling it with room-temperature curing silicone rubber, and allowing it to cure. 【Case Study】 ■ Material: Silicone rubber ■ Initial investment amount (press mold cost): ¥150,000 ■ Product cost: ¥1,000 (lot of 5 pieces) ↓ 《Created a mold using a 3D printer and molded room-temperature curing silicone》 ↓ ↓ ■ Material: Mold: Polylactic acid, Product: Silicone rubber ■ Prototyping cost: Mold: ¥15,000, Product: ¥1,000 (lot of 5 pieces) *For more details, please refer to the PDF document or feel free to contact us.
