3D printing company Seurat is named after pointillist painter Seurat because, like him, the company wants to work pixel by pixel. Rather than trace a laser over the whole build, they want to illuminate and heat every pixel of that layer at once for faster results. Seurat’s production technology is termed Area Printing and uses what it calls Optically Addressed Light Valves (OLAVs). “Every pixel in the OALV defined its own laser spot, effectively creating a multitude of individual lasers out of one very powerful laser” that projects “laser light down to a bed of metal powder, weld weld a patterned area in an instant, and build a multi-layer part.
