3DPrintopia 2025: filament, folding printers, and fun at the East Coast's largest 3D printing event

Tom Hardware Prusa Research
3DPrintopia 2025.

I spent last weekend at Maryland’s 3DPrintopia, a celebration of all things 3D printing. The event is an eclectic mix of the latest tech, mixed with homebrew 3D printers, merchants, and geeks showing off their latest projects. Over 3000 visitors and hundreds of exhibitors gathered, from big company CEOs to Cub Scouts racing their first 3D printed (not-a-pinewood) derby car.

Started in 2018 as the East Coast RepRap Festival, the event has outgrown the community college basketball court it called home for the last several years. In 2026, 3DPrintopia will move to the massive Pennsylvania Convention Center in Philadelphia, with 63,000 square feet of space to spread out on.
