Exhibiting at JRRF provided an invaluable opportunity for direct dialogue with users, leading not only to connections with individual customers but also to successful implementations for companies considering 3D printers.

The scale of the venue and the atmosphere of the booths were comfortable, and it was a wonderful event where you could feel the warmth of the community. The Maker Chips initiative was also excellent, and it was impressive how participants could express their creativity while having fun. I look forward to next year becoming an even more special festival unique to Japan, further highlighting the appeal of RepRap and open source.

JRRF is a vibrant event that carries on the spirit of makers. We have been constantly thinking about how technology can truly change the world. At JRRF, we are attempting to advance technological development through 3D printing technology. This may be just a small step, but it is also a solid step.

Everything about consumer 3D printers was here. JRRF is a one-of-a-kind event where people, products, and information related to 3D printing gather from both Japan and abroad. If you have even the slightest interest in 3D printers, you should definitely come to JRRF!

It was a wonderful event where I could feel the excitement of the 3D printer industry with my whole body! The enthusiasm of the community exceeded my imagination, and being able to hear directly from enthusiasts was truly inspiring. We will work to further accelerate this excitement with our materials. 🔥
