Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a novel dual-wavelength 3D printing technique that enables the clean removal of support structures, potentially overcoming one of the key challenges in additive manufacturing. The new method, detailed in a recent study published in ACS Central Science , uses light of two different wavelengths to simultaneously build complex 3D structures and generate temporary support material from a single resin.
