A volumetric three-dimensional (3D) printing method developed by researchers at Lawrence Livermore National Laboratory (LLNL) that can print objects almost instantly takes advantage of a new class of materials called thiol-ene resins.
These resins may be used with LLNL's volume additive manufacturing (VAM) techniques, including Computed Axial Lithography (CAL), which projects beams of 3D-patterned light into a vial of resin that spins as the light cures the liquid resin into a solid.
Thiol-ene resins can create strong, stretchable, and flexible objects, as opposed to the brittle and breakable objects created using acrylate-based resins in the CAL process.
LLNL's Maxim Shusteff said, "These results are a key step toward our vision of using the VAM paradigm to significantly expand the types of materials that can be used in light-driven 3D printing."
