Title:
３Ｄ印刷された半結晶性及びアモルファスのポリマー物品
Document Type and Number:
Japanese Patent JP7223126
Kind Code:
B2
Abstract:
The invention relates to 3D printed parts made with thermoplastic polymers having a low stiffening temperature. 3D printed parts of the invention have very good Z layer adhesion, have a high elongation at break in the Z direction, preferably of more than 50 percent, and have at least an 80 percent ratio of Z to XY stress at yield or at break. The resulting part may be nearly isotropic—having similar mechanical properties in the XY and Z print directions. The excellent layer adhesion makes the resultant printed part more robust—able to withstand many cycles of use. Certain polymers of the invention produce printed parts that have a very low haze, and are nearly transparent.
