Not sure there is much demand to use carbon fiber in the art space. It caught my eye, that MarkForged is releasing a new 3D printer called the Mark One that can print with carbon fiber.
Sounds like they are marketing this printer as a solution that uses carbon fiber 3D printing to replicate existing parts created from different materials. If strength is a factor in the piece you want to produce, carbon fiber might be an interesting alternative to metal.
