Novel 3D printing tech gets two solid materials out of a single resin | By independently tilting micro-mirrors within the printer to different angles, the two beams of light can be separately directed to different pixel-wide locations within each print layer.
While 3D printing is indeed a burgeoning technology, it's limited by the fact that items can typically only be printed from a single material. A new system still uses just one print resin, but that substance can form into two different solid materials as needed.
In a nutshell, FDM printers produce objects via a nozzle that moves back and forth over a print bed, depositing a filament of molten thermoplastic in successive layers. Developed by scientists from the University of California Santa Barbara and the Lawrence Livermore National Laboratory (LLNL), it utilizes a resin made mainly of epoxy and acrylate monomers.
