Patent number: 11167491Abstract: Multi-film containers for use in additive fabrication devices are provided. According to some aspects, a container may include multiple films that are at least partially detached from one another. In some embodiments, the multiple films may include films formed from different materials. As one example, an upper film may be formed so as to be relatively impermeable to substances within a source material of an additive fabrication device, whereas a lower film may be formed so as to provide desirable mechanical properties. In some cases, the multiple films may be commonly tensioned while being unattached to one another.Type: GrantFiled: May 31, 2019Date of Patent: November 9, 2021Assignee: Formlabs, Inc.Inventors: Benjamin FrantzDale, Konstantinos Oikonomopoulos, Shane Wighton, Dmitri Megretski, Adam Damiano, James Loomis, Christian Reed

Patent number: 10427345Abstract: Process for continuous fabrication of highly aligned polymer films. A polymer-solvent solution is subjected to a high shear, high temperature, Couette flow to extrude a thin film having polymer chain disentanglement. The extruded thin film is frozen and the solvent is allowed to evaporate to form a dried film. The dried film is mechanically drawn using a constant force, adaptive-thickness drawing system to align polymer molecular chains through plastic deformation. A suitable polymer is ultra-high molecular weight polyethylene.Type: GrantFiled: April 30, 2015Date of Patent: October 1, 2019Assignee: Massachusetts Institute of TechnologyInventors: Gang Chen, Jianjian Wang, Jonathan Kien-Kwok Tong, Hadi Ghasemi, Xiaopeng Huang, James Loomis, Yanfei Xu

Patent number: 10072129Abstract: A polymer composite is provided that includes a plurality of heat-absorbing nanomaterials, a plurality of thermally-expanding microspheres, and an elastomeric matrix. In the polymer composite, the heat-absorbing nanomaterials and the thermally-expanding microspheres are dispersed within the elastomeric matrix such that the thermally-expanding microspheres expand and stretch the matrix upon exposure to a thermal stimulus. Methods of forming a thermally-expanding polymer composite are also provided and include the steps of dispersing a plurality of heat-absorbing nanomaterials in an evaporative solvent; combining the dispersion with an amount of an elastomeric material to create a mixture; adding an amount of thermally-expanding microspheres to the mixture; and polymerizing the mixture. Circuits including resistors comprised of the polymer composites are further provided.Type: GrantFiled: February 7, 2014Date of Patent: September 11, 2018Assignee: UNIVERSITY OF LOUISVILLE RESEARCH FOUNDATION, INC.Inventors: James Loomis, Balaji Panchapakesan

Patent number: 8230594Abstract: A tube matrix and the corresponding method of joining a plurality of tubes to a base plate to create the tube matrix. The tube matrix has a base plate from which a plurality of parallel tubes extend. The base plate has holes formed though it to receive the tubes. The tubes are placed into the holes on the base plate. The tubes may have end flares that abut against the base plate and prevent the tubes from completely passing through the base plate. Once the tubes are in place in the holes of the base plate, the tubes and base plate are welded together with individual laser welds. The laser welds enable a very dense matrix of tubes to be welded to the base plate without damaging or obstructing the tubes.Type: GrantFiled: May 9, 2009Date of Patent: July 31, 2012Inventors: Peter R. Bossard, James Loomis

Publication number: 20070089304Abstract: An automatically programmable tilting mechanism for holding a scribe tool at varying angles using an aerostatic bearing. The air bearing secures the scribe tool about its longitudinal shank and generally allows for free axial movement while the tool holding structure prevents rotation of the scribe tool, thus providing extremely fine compliance and force application of the scribe tool point against the substrate. During a scribing process, the tilting mechanism regularly adjusts the angle of the scribe tool relative to the substrate so that a fresh cutting edge is always being employed in the scribing process.Type: ApplicationFiled: October 5, 2005Publication date: April 26, 2007Inventors: James Loomis, Richard Avidano
