Publication number: 20240100777Abstract: A light polymerizable composition for use in the additive manufacturing of medical devices may include a first photo-initiator and a second photo-initiator. The first photo-initiator activates to initiate curing of the composition when exposed to light of a first wavelength in an additive manufacturing device and the second photo-initiator limits the transmission of the light of the first wavelength that activates the first photo-initiator in the additive manufacturing device. The second photo-initiator is activated to further cure the composition when exposed to a light of a second wavelength different from the first wavelength by activating the second photo-initiator to produce free radicals at a higher rate when exposed to the light of the second wavelength than when exposed to the light of the first wavelength.Type: ApplicationFiled: November 27, 2023Publication date: March 28, 2024Inventors: H. David DEAN, Al SIBLANI, Eric J. MOTT, John P. FISHER, Martha O. WANG, Antonios G. MIKOS

Patent number: 11865785Abstract: 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.Type: GrantFiled: June 27, 2017Date of Patent: January 9, 2024Inventors: H. David Dean, Al Siblani, Eric J. Mott, John P. Fisher, Martha O. Wang, Antonios G. Mikos

Publication number: 20190210355Abstract: A light-polymerizable composition for additive manufacturing of resorbable scaffolds and implants comprising a biocompatible resin. The biocompatible resin includes a combination of photo-initiators or a dye-initiator package tailored to manufacture implants with the desired physical and chemical properties. A dye or other constituent controls between layer (z) resolution of the manufactured part built in an additive manufacturing device. A light absorber or other constituent controls within layer (x-y) resolution of the manufactured part.Type: ApplicationFiled: December 24, 2018Publication date: July 11, 2019Inventors: H. David DEAN, Al SIBLANI, Eric J. MOTT, John P. FISHER, Martha O. WANG, Antonios G. MIKOS
