    摘要: A polymer network formed by crosslinking poly(propylene fumarate) with a fumarate derivative. The fumarate derivative is one in which the PPF is soluble, is preferably an alkyl fumarate, and is more preferably selected from the group consisting of diethyl fumarate, dimethyl fumarate, methyl ethyl fumarate, diisopropyl fumarate, and dibutyl fumarate. The network can be formed by photo-crosslinking and can be porous. In some embodiments, the poly(propylene fumarate) and the fumarate derivative are each present in an amount effective to produce a polymeric network useful for in vivo applications. The network can be formed from an injectable, in situ crosslinkable composite formulation, or can be prefabricated from a crosslinkable composite formulation such as stereolithography, rapid prototyping, injection molding, and extrusion molding.

    摘要: A process for additive manufacturing of a resorbable implant to be implanted into a patient includes providing a biocompatible resin including a liquid light-polymerizable material that is resorbable after polymerization and an initiator. The process further includes actuating an additive manufacturing apparatus to expose an amount of the biocompatible resin to light to at least partially cure the exposed amount of biocompatible resin to form a layer of the resorbable implant and actuating the additive manufacturing apparatus to expose at least some additional amount of biocompatible resin to light to at least partially cure the exposed additional amount of biocompatible resin to form an additional layer of the resorbable implant and to at least partially overcure previously cured layers to cause at least some interlayer binding between the previously cured layers and the additional layer.
