Publication number: 20240416583Abstract: Systems, methods, and compositions for using Interfacial Photopolymerization (IPP) for high-resolution digital processing of polymers are disclosed. In IPP, a polymer film can be formed at an interface between two liquids, each containing a species involved in a polymerization reaction. The two liquids can include a photoinitiator and a monomer that are immiscible and/or reactive such that the film can form at the interface. The polymerization reaction can be controlled by a LED light source, which is focused at a reaction zone located at or near the liquid-liquid interface. The resulting polymer results in a high-resolution, high-throughput AM of thermoplastic polymers that enables on-demand production of objects that exhibit exceptional dimensional quality, mechanical properties, and recyclability characteristics.Type: ApplicationFiled: November 7, 2022Publication date: December 19, 2024Inventors: Cecile A.

Patent number: 12070817Abstract: Systems, devices, and methods for additive manufacturing are provided that allow for components being manufactured to be assessed during the printing process. As a result, changes to a print plan can be considered, made, and implemented during the printing process. More particularly, in exemplary embodiments, a spectrometer is operated while a component is being printed to measure one or more parameters associated with one or more layers of the component being printed. The measured parameter(s) are then relied upon to determine if any changes are needed to the way printing is occurring, and if such changes are desirable, the system is able to implement such changes during the printing process. By way of non-limiting examples, printed material in one or more layers may be reheated to alter the printed component, such as to remove defects identified by the spectrometer data.Type: GrantFiled: November 28, 2022Date of Patent: August 27, 2024Assignee: Massachusetts Institute of TechnologyInventors: Ryan Wade Penny, Anastasios John Hart
