Make plastic printed circuits with a standard laser cutter - YouTube
"Have you tried acrylic or polycarb sheet instead of 3d prints for flat parts? (..) There is a UK company that has a process where they inkjet print catalyst, then electroless plate - a few years ago they did a transparent arduino. I wonder if there may be a way to pattern the catalyst to avoid needing a laser- screen-print perhaps?" / "Looking back now, it seems having this process work on thin, plain acrylic sheets would actually be pretty useful as well. (..) Inkjet printing the catalyst sounds pretty good. I was hoping the laser method would also eventually work on contoured parts (would require more movement axes in the laser cutter), and inkjet should work in this regard as well."

Ceramic–metal composites for heat exchangers in concentrated solar power plants | Nature
New hybrid ceramic for use in heat exchangers. Start with a titanium carbide porous block, immerse in a copper and zirconium bath. The zirconium infiltrates the ceramic and displaces titanium in the carbide, while the titanium migrates into the open pores. Copper ends up being a thin film sealant.
