Additive manufacturing carrier platform with window damage protection features

摘要

A carrier plate assembly for use in producing a three-dimensional object by bottom-up stereolithography includes: (a) an upper support; (b) an adhesion plate having a substantially flat planar lower adhesion surface, on which surface the three-dimensional object can be formed; (c) at least one energy absorber interconnecting the upper support and the adhesion plate; and (d) a carrier lock portion connected to the upper support.
