| description | The invention discloses a starch-filled PVA supporting material used for 3D printing, and a preparation method thereof. The main body material of the supporting material is polyvinyl alcohol (PVA), a biological raw material starch is used to fill, and a plasticizer and a lubricant are used as auxiliary materials; and blending extrusion of a PVA and starch mixture is carried out under guaranteed extrusion conditions by using a single screw extruder. The main components PVA and starch of the water-soluble 3D printing supporting material prepared from the starch-filled PVA composite material are environmentally friendly, so the supporting material has the advantages of easiness in degradation, good biocompatibility, good glossiness, good transparency, good hand feeling and good heat resistance. The supporting material is especially suitable for printing hollow-out products or hollow products, and can be very easily peeled from molded parts without damaging the profile of the molded parts due to complete dissolut |
