Replicating a Science Paper: Ultralight Metallic Microlattices
A team of researchers created ultralight metallic microlattices back in 2011... and I tried to replicate their result using commercially available, off-the-shelf materials.
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/)
