Luke,

Hyrel printers do not require proprietary filaments, and can print with every filament we've tried, from PLA to Ninjaflex to PEEK. We also print in clays and pastes like Fimo, Sculpey, porcelain and even Sugru.

Please PM me if you'd like a skype/teamviewer session with no obligation. Our unenclosed Engine is available for $2000 with one basic head right now ($2500 list), plus shipping.
