New 3D Printing Method Builds Leak-Free Parts in Just 20 Seconds

New 3D printing method builds leak-free parts in just 20 seconds

University of Utah researchers have developed a 3D printing method that creates solid microstructures in a single laser exposure, eliminating the weak seams typically left behind by conventional layer-by-layer printing. The process completes a print in about 20 seconds, offering a much faster alternative to existing laser-based techniques that can take hours. The team achieved this by using a nanoscale mask that reshapes laser light into a holog…

University of Utah Develops Holographic 3D Printer That Completes Prints in 20 Seconds

University of Utah engineers have built a 3D printer that produces complete shapes in a single exposure rather than building them layer by layer
