title = "Rapid, large-volume, thermally controlled 3D printing using a mobile liquid interface",
abstract = "We report a stereolithographic three-dimensional printing approach for polymeric components that uses a mobile liquid interface (a fluorinated oil) to reduce the adhesive forces between the interface and the printed object, thereby allowing for a continuous and rapid print process, regardless of polymeric precursor. The bed area is not size-restricted by thermal limitations because the flowing oil enables direct cooling across the entire print area. Continuous vertical print rates exceeding 430 millimeters per hour with a volumetric throughput of 100 liters per hour have been demonstrated, and proof-of-concept structures made from hard plastics, ceramic precursors, and elastomers have been printed.",

note = "Funding Information: We thank M. Flynn and J. Valdillez for their assistance in developing the light-patterning engines and software used to operate the printer, J. Fernandez for his contributions to understanding of the fluidic flow behavior and the CAD design of objects printed on the HARP process, and R. Davis, R. Schmidt, and E. Cottiss for their assistance in designing and analyzing resins for the printer. This material is based on work supported by the Air Force Office of Scientific Research under award FA9550-16-1-0150 (to develop the HARP technology, to perform the velocimetry and thermal imaging, and to develop the ceramic resin); the Center for Bio-Inspired Energy Science, an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science, Basic Energy Sciences under award DE-SC0000989 (initial UV-curable rigid urethane resin formulation); the Sherman Fairchild Foundation Inc. (initial UV-curable flexible urethane resin formulation); and a National Defense, Science and Engineering Graduate Fellowship (J.L.H.). CT imaging work was performed by A. Brikha at the Northwestern University Center for Advanced Molecular Imaging, supported by NCI CCSG P30 CA060553 awarded to the Robert H. Lurie Comprehensive Cancer Center.",
