Abstract:

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.

B33Y 80/00

Abstract:

A cosmetic part is formed via compression molding in a single molding operation with no post processing by forming an assemblage of feed constituents, wherein the assemblage includes plural fiber-bundle-based preforms and one or more resin-only constituents, the latter configured and positioned as appropriate to create resin-rich cosmetic layers where desired on the part.

Abstract:

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 ().
