A "3D printer" can create intricate three-dimensional models simply by reading CAD data that you want to shape, using an inkjet method. It facilitates the early detection of issues and leads to new ideas and innovations that may not have been noticed in the 3D CAD. Additionally, if the 3D printer uses ABS resin as the model material, it allows for functional and assembly verification, making it possible to shorten the period for prototype and mold manufacturing. We offer the desktop 3D printer 'OBJECT 30' and the 'STL・3D Method,' which can accurately reproduce the fine nuances and details of designs. 【Benefits of 3D Printers】 ■ You can experience the actual image before entering product manufacturing. ■ It enables shapes that are close to the real thing. ■ It helps shorten the design and development period. *For more details, please refer to the catalog or feel free to contact us.
