  • SUPPORT MATERIAL FOR FUSED DEPOSITION MODELING, AND MANUFACTURING METHOD OF FUSED DEPOSITION MODELED STRUCTURE AND THREE-DIMENSIONAL OBJECT USING SAME
    Publication number: 20230182401
    Abstract: Provided is a support material for fused deposition modeling capable of being supplied in the form of filament excellent in flexibility and uniformity of wire diameter. The support material comprises a polyvinyl alcohol-based resin (A) and a polylactone (B) having a specific molecular weight in a specific content. The filamentous support material is excellent in productivity. Moreover, the support material portion after the fused deposition modeling can be removed by washing by use of water. The resulting waste liquid is biodegradable and thus the support material is environmentally friendly.
