The Most Promising 3D Printer That Nobody Uses Anymore

Color 3D printing once looked like the future… but today, almost nobody uses it anymore. Thanks to our channel sponsor PCBWay for sponsoring this video: https://www.pcbway.com In this video, I revive a forgotten Color Jet Printing machine (ProJet 660), repair it live, and explain why this incredibly promising technology quietly disappeared. We take a deep dive into: – how Color Jet Printing actually works – why it was once considered revolutionary – what went wrong (cost, materials, durability, and competition) – and whether it still makes sense today As a bonus, I turn myself into a 3D printed figurine using AI image-to-3D modelling and print it on this machine to see what’s really possible with this “dead” technology. This isn’t just about fixing a broken printer — it’s about understanding why some technologies fail, even when they look amazing on paper.
