Systems and methods for resin recovery in additive manufacturing

A method of producing multiple batches of objects by stereolithography, includes the steps of: (a) dispensing an initial or subsequent batch of dual cure resin into a stereolithography apparatus, the resin including a light polymerizable component and a heat polymerizable component; (b) producing an...

Beschreibung
Zusammenfassung:	A method of producing multiple batches of objects by stereolithography, includes the steps of: (a) dispensing an initial or subsequent batch of dual cure resin into a stereolithography apparatus, the resin including a light polymerizable component and a heat polymerizable component; (b) producing an intermediate object by light polymerization of the resin in the apparatus, wherein the intermediate object retains excess resin on a surface thereof; then (c) separating excess resin from the intermediate object; (d) blending the excess resin with additional dual cure resin to produce a subsequent batch of dual cure resin; (e) repeating steps (a) through (c), and optionally repeating step (d), to produce additional object(s); and (f) baking the objects, together or separately, to produce multiple batches of objects.
