The 3D print was only able to bear a 10g cargo with its original size but could handle 25 times more weight once the foam expanded.Īccording to the research team, this material could also be used to build airfoils or expandable astronaut habitats. To highlight this potential, the researchers 3D printed a tiny boat and tested the load it could handle before and after the heating process. Lightweight applications are the first area such material could be involved in, as it could help design more efficient, lighter buoyancy systems. Obviously, such research wouldn’t have been achieved without clear applications, which, according to the UC San Diego team, are many. Watching foam expand on footage sure looks very satisfying, now, one may wonder what 3D printing expandable materials would exactly allow for. Why 3D Print objects with expandable foam? The heat decomposed the blowing agent which made the sphere 40 times bigger than before the process. To allow it to expand, they heated it at a 200 ☌ temperature over a 10 mins time period. Once the right balance was achieved, the research team 3D printed a lattice sphere. Step 2 was hence to find the right concentration of these 3 components to get the final mixture completed. To turn HEMA into a usable foam, the team had to add two materials to it: Photoinitiators, which are required to allow resins to be cured, and a blowing agent that would allow the material to expand. After carrying out different tests, the researchers found out that 2-hydroxyethyl methacrylate (otherwise referred to as HEMA) would present the fast curing time they needed. The first stage of development aimed at selecting a monomer, a material the team could use as a basis for their resin formulation. Stereolithography is a process of 3D Printing objects using patterns of light along with UV-curable resin polymers. To come up with such kind of material, the UC San Diego research team decided to focus on SLA technologies. Jonathan Pokorski, David Wirth, and their research team wanted to develop an expandable material that any users could have access to, even with cheap, commercial 3D printers.
