Gutenberg
Gutenberg is committed to "pioneering new horizons in manufacturing" and produces domestically made FFF 3D printers in Ota City, Tokyo. Our printers are Made in Japan, designed, metal-processed, and assembled entirely by our in-house team of Japanese engineers. The high-performance resin filament series "POTICON," developed jointly with Otsuka Chemical, supports super engineering plastics such as PA, PPS, and PEEK, further expanding the possibilities of FFF 3D printing. Our flagship G-ZERO series combines high-speed printing with a maximum speed of 700 mm/s and an acceleration of 30,000 mm/s2, along with the durability required for industrial applications. These printers are used across various manufacturing environments, from university research labs to space development sites. At our booth, we will exhibit actual printers as well as printed samples using POTICON filaments. Please feel free to stop by!
