Water Soluble PVA Filament

Water Soluble PVA Filament, Inventables, $89.50/kg

Here’s another “exotic” printing material choice sure to be appreciated by the adventurous home 3D printer, especially anyone with a Makerbot Replicator or other dual-extrusion capable fused filament printer. PVA (poly-vinyl alcohol, not to be confused with poly-vinyl acetate, the stuff white glue is made of) extrudes like normal 3D-printing plastics but has the special property of being completely soluble in water. You can use it to print fully bio-degradable, entirely water-soluble objects (like Tony Buser’s seed bombs, shown above), or as support material in a dual-extrusion printer to produce objects with complex overhangs and internal spaces, like Tony’s Hilbert cube.
