Title:
COMPOSITION AND METHOD FOR SELECTIVE LAMINATING
Document Type and Number:
Japanese Patent JP3396200
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to produce a three-dimensional object with a minimum curling, delamination and stress cracking at a rate faster than known rates by a selective laminating technique using a disclosed composition.
SOLUTION: A phase transition composition is used which is solid at an ambient temperature and liquid at a temperature higher than the ambient temperature so that it is advantageous for use in a selective laminating method for shaping a three-dimensional object. The composition is a mixture of semicrystalline polar and non-polar components and has a freezing point of at least about 68°C, a melting point of at least 88°C and a viscosity of about 13 cP at 135°C. It contains two or more waxes having a wide melting point range and a wide molecular weight range.
