The authors used a special self-propagating photocurable resin, electroless nickel plating and a special solution to dissolve the resin. I have a cheap resin printer and some DIY copper/nickel electroplating baths. In this video we see if we can recreate their result, and work through the challenges of COTS materials. I started with resin prints + copper/nickel plating, but due to gas pressure during thermal decomposition of the resin, eventually switched to PLA FDM printing. Less beautiful lattices, but more encouraging results :) Lattices and TPMS were generated with nTop (http://ntopology.com/) Schaedler, Tobias A., et al. "Ultralight metallic microlattices."
