{"product_id":"ultimaker-pva-support-filament-750g","title":"UltiMaker PVA Support Filament 750g","description":"\u003cp\u003ePVA is a support material that dissolves in water, and it is the reason dual extrusion is worth having. Print the part in PLA and its supports in PVA, drop the finished print in a tub of water, and the supports simply disappear - leaving clean surfaces inside cavities and under overhangs that no amount of careful snapping and sanding would achieve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e750g spool, natural\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2.85mm diameter\u003c\/strong\u003e - for UltiMaker S series printers\u003c\/li\u003e\n\u003cli\u003eWater-soluble - no solvents or tools needed\u003c\/li\u003e\n\u003cli\u003ePrint profiles built into UltiMaker Cura\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThis needs a dual-extrusion printer.\u003c\/strong\u003e PVA is printed alongside a build material in the second extruder, so it only works on an UltiMaker S series machine with two print cores loaded.
