Abstract
The invention relates to additive manufacturing (AM) and in particular to a degradable material for use in applications that require temporary structure stability, such as in investment casting or biomedical applications or as a temporary support material.
Claims20
A three dimensional printing method for producing a self-destructible temporary structure, comprising:
- depositing a degradable material solution comprising a degradable component;
- depositing a disintegrating agent solution comprising a disintegrating agent capable of disintegrating the degradable component;
- solidifying a combined disintegrating agent and degradable material solution to form a solid, semi solid or gel layer;
- and
- repeating said steps of depositing and solidifying layers until the self-destructible temporary structure is formed,
- wherein after solidification, the disintegrating agent gradually degrades the degradable component to disintegrate the self-destructible temporary structure.
