Japan’s Kuraray has developed a 3D printing filament for use in FFF (Fused Filament Fabrication) additive processes. The water-soluble, biodegradable filament is based on the company’s Poval polyvinyl alcohol (PVOH) resin, which is commonly used in adhesives, paints and coatings, wood primers, paper and textile applications, cosmetics and emulsions, among others.
The material sold under the Mowiflex brand has excellent adhesion to other resins such as polylactic acid (PLA), polyamide (PA), polyvinyl butyral (PVB) and thermoplastic polyurethane (TPU). Mowiflex filaments can therefore be used as a carrier material for 3D printed products that contain undercuts, moving parts and other complex shapes. Mowiflex is soluble in cold water.
