Full Color 3D Printer Upgrade Leaves Competition In The Dust

August 18, 2016 by 45 Comments

Most hobby 3D printers are based on FDM, extruding a single-color noodle of melted plastic to build up an object. Powder-based inkjet 3D printing allows you to print detailed, full-color models from a plaster-like material. The process uses ink and water droplets, dispensed from an inkjet print head to selectively fuse and color layers of a powdered binder material. When you see an offer for a 3D printed miniature version of yourself (or someone else), they are made with powder. [Aad van der Geest] wants to put this technology on your desktop with ColorPod, a kit that converts your FDM printer into a powder printer.

MRRF: Innovating Extruders And Dissolvable Filament

March 30, 2016 by 6 Comments

Think laying down molten plastic on a 3D printer is as easy as squeezing plastic filament out of a hot tube? It’s not, and anyone who had a 3D printer in 2009 would tell you as such. There were hobbed bolts that stripped the plastic into a gooey paste, extremely large x carriages that made everything wobbly, and nothing worked as well as it does today.

Technology marches on, and this year’s Midwest RepRap Festival had people showing off the latest advances in pushing plastic, and something that hasn’t seen much use yet – dissolvable filament.
