Meet the Polymaker – your weekly front-row seat to the world of 3D printing! 🖨️✨
Every week, I bring you the latest and most interesting 3D printing news, spotlight incredible prints from our amazing community, and sit down with a new maker to hear their story. From industry pros to hobbyists with jaw-dropping projects, each episode is a chance to learn, get inspired, and connect with the people pushing the limits of what’s possible.
✨ Tonight’s Guest: Yuto (@psych0h3ad)
Yuto, known as @psych0h3ad, is a 29-year-old office worker at a foreign manufacturing company who describes 3D printing as simply a hobby. In reality, that hobby has grown into something much larger, with over 20 3D printers running at home and a deep involvement in the maker community.
Tonight, we will talk about how Yuto got started in 3D printing, what led him to scale up to running so many machines, and how he approaches balancing a full-time job with such a demanding hobby. We will also dive into JRRF 2025, an event he organized on his own in just three months that brought in more than 1,500 visitors, and what it takes to pull something like that off. We will also talk about JRRF 2026 coming up at the end of May in Tokyo, Japan.
If you are curious about scaling your setup, building something meaningful as a hobby, or getting more involved in the community side of 3D printing, this is one you will not want to miss. 🖨️✨
