Title:
MATERIAL FOR HOT MELT EXTRUSION SYSTEM, MODELING MATERIAL FOR 3D PRINTERS, METHOD FOR PRODUCING MODELING MATERIAL FOR 3D PRINTERS, AND THREE-DIMENSIONAL MODEL
Document Type and Number:
WIPO Patent Application WO/2020/158647
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a material for hot melt extrusion system, which has excellent elastic modulus, while forming a model that has excellent dimensional stability under high temperature high humidity conditions; a modeling material for 3D printers; a method for producing a modeling material for 3D printers; and a three-dimensional model.　A material for hot melt extrusion system according to the present invention contains at least a cellulose derivative and an additive, and is characterized in that: the cellulose derivative is a cellulose acetate propionate and satisfies formula (1) and formula (2), wherein X is the degree of substitution of acetyl groups and Y is the degree of substitution of propionyl groups; and the additive contains a plasticizer and a compound A having a partial structure that has an NICS value within the range of from -14 to -10 (inclusive).　Formula (1): 2.0 ≤ X + Y ≤ 3.0 Formula (2): 0.5 ≤ Y ≤ 2.6
