Title:
重合された材料で作られる物品を製造する方法
Document Type and Number:
Japanese Patent JP7136815
Kind Code:
B2
Abstract:
Disclosed is a method for manufacturing an article made of a polymerized material including the steps of: —providing a vat of polymerizable material, transparent at least in the 400-800 nanometers wavelengths range, —irradiating the polymerizable material with a laser beam according to a predetermined pattern so as to polymerize the polymerizable material in order to form the article, the predetermined pattern being determined based on a three-dimension representation of the article with the positions in three dimensions of a plurality of volume units adapted to form together the article, the laser beam scanning the vat in three dimensions in order to be focused at each position of the volume units present in the predetermined pattern so as to initiate locally the polymerization of the polymerizable material at each of these positions.
