Northwestern University researchers have developed a stereolithographic 3D printer that can print an object the size of an adult human in just a couple of hours. Called HARP for high-area rapid printing, this printer uses a patent-pending version of stereolithography that circulates liquid plastic to remove heat, which can cause printed parts to crack and deform. To dissipate the heat that is generated from the polymerization of the resin, HARP prints vertically and uses a nonstick liquid that behaves like Teflon. The printer projects ultraviolet light through a window to solidify resin...Read full articleRelated content from Photonics MediaARTICLESMicrofluidics Device 3D-Printing Innovates Biomedical FabricationResearchers at the University of Southern California (USC) developed a printing technique that could provide the precision required to successfully 3D-print microfluidic channels on chips at a scale...Photonics.com 4/14/2022Laser Process Prints Defect-free Custom Alloy PartsA study from a Texas A&M University research team could make it easier to print uniform, defect-free parts using the laser bed powder fusion 3D-printing technique with metal alloys.
