MATERIAL FOR HOT MELT EXTRUSION SYSTEM, MODELING MATERIAL FOR 3D PRINTERS, METHOD FOR PRODUCING MODELING MATERIAL FOR 3D PRINTERS, AND THREE-DIMENSIONAL MODEL

摘要

A material for a hot melt extrusion method contains at least a cellulose derivative and an additive. The cellulose derivative is cellulose acetate propionate and when a degree of substitution of an acetyl group is X and a degree of substitution of a propionyl group is Y, the cellulose derivative satisfies the following Expression (1) and Expression (2); and the additive contains a plasticizer and a compound A containing a partial structure having a NICS value in the range of −14 or more and −10 or less,;
