What is JRRF? — A Festival of 3D Printers and Making, Gathering Over 140 Booths
JRRF (Japan RepRap Festival) is a community event that inherits the spirit of the open-source 3D printer culture 'RepRap,' spreading the joy of making and knowledge exchange centered around 3D printers. A major feature is the ability to see, touch, and talk about actual machines, from homemade 3D printers to the latest commercial models. It gathers a diverse range of participants, from those touching a 3D printer for the first time to veteran makers, corporate representatives, popular YouTubers, and overseas creators.
Expanding the venue size to double that of last year's inaugural event, this year has grown to a scale of over 140 booths in total, including 44 sponsoring companies and 41 corporate exhibition booths. A wide range of genres related to manufacturing will gather in one place at the venue, including homemade 3D printers, high-speed FFF printers, filaments, 3D scanners, CAD software, AI modeling, CNCs, laser processors, and various accessories. In addition to exhibitions, there are plenty of demonstrations, interactive booths, workshops, actual machine experiences, and sales booths, making it a place to experience the forefront of digital fabrication. The faces of the exhibitors, as well as the visitors, are truly diverse. While beginners can easily enjoy it, it is also an event full of stimulation for those who want to discuss things deeply. Unlike a typical exhibition, JRRF aims to be a place where people who love 3D printers gather regardless of their positions, connect, and where new discoveries and interactions are born.

■ A Highly International Event
JRRF 2026 is a highly international event that attracts participants from both home and abroad. There are many exhibitors and visitors from overseas, and the official website is available in three languages: Japanese, English, and Chinese.
We also plan to invite overseas 3D printing content creators and announce new products. We will gradually release more information, including the invitation of the JCJC team and RC demonstrations, offering exhibitions and experiences not previously seen in Japan.
This year's JRRF will have exhibitors and visitors from overseas. We understand the feeling of hesitating, thinking, 'I don't speak English...' But won't you muster up a little courage? There are volunteer interpreters at the venue, and translation apps and AI are quite excellent nowadays. But I think the most effective way to communicate is to speak to them in your own words, even if it's clumsy. 'Hi!' 'I like your work!' — Just that should make the other person incredibly happy. Even if your words aren't perfect, the feeling of loving 3D printers is
