What is volumetric 3D printing and why it could mean the end of additive manufacturing

By using laser-generated, hologram-like 3D images flashed into photosensitive resin, researchers at Lawrence Livermore National Laboratory, along with academic collaborators, have discovered they can build complex 3D parts in a fraction of the time of traditional layer-by-layer printing. With this process, researchers have printed beams, planes, struts at arbitrary angles, lattices and complex and uniquely curved objects in a matter of seconds. Progress moves fast in the 3D printing industry. So much so that new, disrupting technologies are announced almost every month. However, they can’t all be disrupting and revolutionary. So it happens that when a truly disruptive new approach to 3D printing is announced it may go somewhat unnoticed – or fully understood for its importance. That may have happened when LLNL researchers first announced and presented volumetric 3D printing last year . But exactly what is volumetric 3D printing? Even if it was a project from top […]
