CES2017: Dissolvable Support Material

Posted on by

Over the last year, it seems the next big thing in 3D printing is dual and multi-extrusion. This gets you multi-colored objects, but if you have the right filament, it also allows you to print objects that would otherwise be impossible to print. This week, Airwolf 3D announced their HydroFill water soluble support material. They had a few sample prints and a fish tank, and yes this stuff does dissolve in water quickly.

There were a few problems with dissolvable support material in the past. PVA is water soluble, but it doesn’t print well. HIPS can be dissolved in limonene, …read more

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.
