THREE-DIMENSIONAL PRINTING PROCESS FOR PRODUCING A SELF-DESTRUCTIBLE TEMPORARY STRUCTURE

摘要

A three dimensional printing method for producing a self-destructible temporary structure, comprising: depositing, layer by layer, a degradable material solution having a biosynthetic copolymer as a degradable component and a disintegrating agent solution comprising enzyme as the disintegrating agent, wherein the disintegrating agent is capable of disintegrating the degradable component. The steps include curing deposited layers to form gel layers and activating the disintegrating agent by an external trigger during or after depositing the disintegrating agent to gradually degrade the degradable component.

1. A three dimensional printing method for easy removal of a support construction, comprising:
depositing a modeling material to form a three-dimensional object, said modeling material comprising a disintegrating agent; depositing a support material to provide a support construction adjacent to the three-dimensional object, said support material comprising a degradable component degradable by the disintegrating agent; hardening said modeling material and said support material,wherein after hardening the disintegrating agent is released into the support material at the interface between the modeling and support materials, enabling easy removal of the support construction from the three dimensional object.
