Methods Of Producing Three-Dimensional Objects From Materials Having Multiple Mechanisms Of Hardening

Patent No. EP3158400 (titled "Methods Of Producing Three-Dimensional Objects From Materials Having Multiple Mechanisms Of Hardening") was filed by Carbon on Jun 22, 2015. The application was issued on Jun 1, 2022.

Patent Summary

A method for fabricating three-dimensional objects involves filling a build region, defined by a carrier and an optically transparent member's build surface, with a polymerizable liquid. This liquid comprises a light-polymerizable first component and a distinct, second solidifiable component. Light irradiation through the transparent member forms a solid polymer scaffold from the first component, while the carrier advances to create a three-dimensional intermediate containing the second component in unsolidified form. Subsequently, the second component is solidified via heating or microwave irradiation, optionally including curing. The resulting object consists of a polymer blend, interpenetrating polymer network (IPN), semi-IPN, or sequential IPN. This process is particularly applicable for producing tough elastomers, such as polyurethanes, polyureas, or silicones.
