Better Than a Toolchanger? This Printer Has 18 Hotends!

🛠️ Custom PCBs, CNC, & 3D printing parts at PCBWay: https://pcbway.com [AD]

For this video, I traveled to Tokyo for the Japan RepRap Festival 2026 to find the best new 3D printing innovations. I dive into the MEWron, a modified Voron using a 4kV electric field to print microscopic microfibers, and showcase a mind-blowing printer with an 18-hotend wheel. Learn more about a zero-clog potassium-titanate filament, a dual-bed Frankenstein Prusa upgrade, and a new sheet that lets you print PETG on a completely cold bed.
