Highly Expandable Foam 3D Printing
UC San Diego NanoEngineering researchers have developed a highly expandable foaming resin for use with SLA 3D printers. This material expands with heat after UV-curing, which enables you to make parts significantly larger than the build volume of the printer used to fabricate them. It could eventually be used for architecture, manufacturing, aerospace, energy, biomedicine, and even to build flotation devices. Read more for a video and additional information.



The models you see above were 3D printed on an Anycubic Photon at 1x scale and heated at 200°C for up to 10-minutes, and once the desired temperature was achieved, it decomposed the blowing agent, thus activating the foaming action of the resin and expanding their size. Researchers calculated the volumetric expansions of up to 40x, making it perfect for aerofoils or buoyancy aids in the real world.
