How is FDM Better than CBAM?
Well the CBAM stuff is SUPER new, requires a lot more work done by hand (currently), and is going to be WAY expensive compared to widely used FDM machines.

Seems to me like a carbon fiber mixed filament is a cheaper way to go, with a possible annealing process to get the tensile strength up post-print.

Try locating a CBAM printer for $200! Maybe if the process becomes quicker, and the machines/materials cheaper to purchase, we could be using this method more in the future. I feel that we will likely advance the materials we have with FDM much faster than this other process would catch on and become affordable.
