A new 3D printing method developed by researchers at CUHK and USC eliminates the need for STL files in laser additive manufacturing.
By directly converting implicit geometries into optimized laser scanning toolpaths, the team achieved record-high printing resolution, faster computation, and stronger, smoother microscale metallic lattices.
This STL-free hybrid toolpath strategy reduces memory by 90%, shrinks wall thickness to 65 μm, and boosts strength by up to 66%. Applications range from aerospace brackets to copper heat exchangers.
