Title: ADDITIVE MANUFACTURING USING FOAMING RADIATION-CURABLE RESIN
Abstract:
SLA-based additive manufacturing using radiation-curable foams enables the production by 3D printing of lightweight parts having desirable physical and functional attributes. A representative method of manufacturing such items includes processing a radiation-curable resin in liquid form to produce a stable, non-aqueous radiation-curable foam, on-demand deposition of the foam at a build layer of a build surface within a 3D printer, and then curing the non-aqueous radiation-curable foam to produce a layer of a 3D build item. Processing the resin typically includes agitation, mixing, shaking, gas injection, ultrasonic stimulation, or combinations thereof. 3D articles of manufacture made by the above-described manufacturing process are also provided.
