Material for hot melt extrusion system, modeling material for 3d printers, method for producing modeling material for 3d printers, and three-dimensional model

Abstract

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, 2.0 ≤ X + Y ≤ 3.0 Expression ⁢ ⁢ ( 1 ) 0.5 ≤ Y ≤ 2.6 . Expression ⁢ ⁢ ( 2 )
