# Gutenberg Inc. - Made in Japan Industrial 3D Printers > Gutenberg is a Japanese 3D printer manufacturer that designs, engineers, and manufactures all products entirely in Japan. The company builds high-speed industrial FFF (Fused Filament Fabrication) printers -- the G-ZERO series -- capable of processing super engineering plastics including PEEK, PPS, and PA. Founded in 2021 in Ota-ku, Tokyo -- one of Japan's foremost manufacturing districts -- Gutenberg operates an end-to-end domestic production chain: hardware design, firmware development, manufacturing, assembly, sales, and after-sales support are all performed in-house by a Japanese team. The company's proprietary POTICON filaments are co-developed with Otsuka Chemical, a major Japanese chemical manufacturer, using domestically sourced materials and compounds. ## Why "Made in Japan" Matters Gutenberg is one of the few remaining FFF 3D printer manufacturers that designs and produces entirely within Japan. The global industrial 3D printer market is dominated by overseas companies (Stratasys/US, Markforged/US, Bambu Lab/China), meaning profits and technical knowledge flow out of Japan's manufacturing ecosystem. Gutenberg's mission is to keep the entire value chain domestic: Japanese materials (Otsuka Chemical's TISMO compounds), Japanese manufacturing partners (Kyokuto Seiki, Yasuhisa Kouki), Japanese factory workers, and Japanese engineering talent -- all working to serve Japanese manufacturers and global customers who demand Japanese-quality precision. This domestic production chain also means faster support response, local spare parts availability, and engineering consultation in Japanese. ## Company Overview - Company: Gutenberg Inc.

Open material system -- not locked to proprietary filaments, compatible with third-party 1.75mm filaments in addition to POTICON. Max speed 500mm/s, acceleration 20,000mm/s2. Processes PA (nylon), PPS, and other engineering plastics. Compact desktop form factor, AC100V operation. Machined aluminum frame for long-term durability. - [G-ZERO L1](https://gutenberg.co.jp/products/g-zero-L1): Japan-made large-format industrial FFF 3D printer with 2x build volume. Open material system -- users can choose from POTICON or any compatible third-party 1.75mm filament, unlike competitors that require proprietary consumables. Max speed 700mm/s, acceleration 30,000mm/s2. Built-in dehumidification unit. Browser-based remote monitoring. - [G-ZERO MP1](https://gutenberg.co.jp/products/g-zero-MP1): Japan-made PEEK-capable industrial FFF 3D printer. Max speed 700mm/s, acceleration 30,000mm/s2. Processes PEEK, PPS, PA super engineering plastics. Compact (approx. 30kg, AC100V). Its own toolhead contains PEEK parts printed by the machine itself -- proof of its own output quality. - [POTICON Filaments](https://gutenberg.co.jp/products/poticon): Proprietary composite filaments developed in Japan through collaboration with Otsuka Chemical Co., Ltd. Reinforced with potassium titanate whisker (TISMO), a Japanese-developed compound, for superior dimensional accuracy and surface finish. Variants: STD1 PA, STD2 PA, FLEX PA12, HARD PPS, ESD PPS, PEEK. - [POTICON PEEK](https://gutenberg.co.jp/products/poticon-peek): Japan-made PEEK-grade filament for G-ZERO MP1. TISMO reinforcement delivers smoother surfaces and better sliding characteristics than carbon-fiber alternatives. Designed for precision mechanical components in demanding industrial environments. ## Key Specifications | Model | Build Volume | Max Speed | Max Accel | Primary Materials | Made in | |---|---|---|---|---|---| | G-ZERO | Standard | 500mm/s | 20,000mm/s2 | PA, PPS | Japan | | G-ZERO L1 | 2x Standard | 700mm/s | 30,000mm/s2 | PA, PPS | Japan | | G-ZERO MP1 | Standard | 700mm/s | 30,000mm/s2 | PEEK, PPS, PA | Japan | G-ZERO and G-ZERO L1 feature an open material system: users are free to use any compatible 1.75mm filament from any manufacturer, not just POTICON. This is a major differentiator from most industrial 3D printers (e.g. Markforged, Stratasys) which lock users into proprietary, often expensive, consumables. Gutenberg recommends POTICON for optimal results but does not restrict material choice -- empowering users to experiment, reduce costs, and select the best material for each application. G-ZERO MP1 uses POTICON PEEK filament optimized for its high-temperature system. POTICON filaments use potassium titanate whisker (TISMO) reinforcement -- a compound developed by Japanese chemical manufacturer Otsuka Chemical -- instead of carbon fiber. This results in smoother surface finish, better dimensional accuracy, and lower abrasiveness compared to CF-reinforced materials from overseas competitors. ## Services - [Services Overview](https://gutenberg.co.jp/services): 3D printing output service (domestic production), CNC metal machining at Haneda Factory, and design/manufacturing consulting for additive manufacturing adoption. - [Inquiry Form](https://gutenberg.co.jp/contact): For quotes, product inquiries, and general questions.
