TECHNOLOGY LICENSING OPPORTUNITY: True Silicone DLP Printing Platform

Summary from the notice

The True Silicone DLP Printing Platform from Los Alamos National Laboratory allows for more geometries in producing genuine silicone parts, gaskets, lattices, prosthetic components or microfluidic devices on an off-the-shelf desktop printer typically required by specialty extrusion equipment. The result is a material whose polymer backbone is built entirely of silicon-oxygen bonds rather than the carbon-based linkages that quietly compromise so-called silicones on the market today. The True Silicone DLP Printing Platform unlocks that capability through a precursor resin and a paired printing workflow that together deliver real silicone parts free of metal catalyst residues, with tunable porosity, geometric complexity and the aging stability that demanding applications require. How it Works The platform begins with a printable resin that blends a polymerizable scaffold with a curable siloxane component, along with a photoinitiator and a small amount of a light-absorbing dye to control polymerization depth. A standard DLP printer cures the acrylic scaffold layer by layer to lock the geometry in place, after which the part is heated so the siloxane oligomers crosslink into a continuous silicone network alongside the scaffold. A wash in ethanol, water or ammonium hydroxide then dissolves the sacrificial scaffold, leaving behind a pure silicone object whose polymer backbone consists solely of silicon–oxygen bonds and retains a porous structure where the sacrificial scaffold was re…
