ENHANCING ADHESION OF OBJECTS TO CARRIERS DURING ADDITIVE MANUFACTURING

A method of making a three-dimensional object from a light polymerizable resin, includes the steps of: (a) producing an object adhered to a carrier plate by light polymerization of the resin in a bottom-up stereolithography process (e.g., continuous liquid interface production); (i) the object inclu...

Zusammenfassung:	A method of making a three-dimensional object from a light polymerizable resin, includes the steps of: (a) producing an object adhered to a carrier plate by light polymerization of the resin in a bottom-up stereolithography process (e.g., continuous liquid interface production); (i) the object including a carrier plate adhesion portion, a main body portion, and a circumferential boundary portion included in the carrier plate adhesion portion and optionally extending into at least part of the main body portion; (ii) the stereolithography process including overexposing the boundary portion (as compared to the exposure of the adhesion portion or main body portion) with light; (b) optionally cleaning the object; and then (c) optionally baking the object to produce a further cured three-dimensional object.
