Which materials can be vapor smoothed?
Vapor smoothing works on thermoplastics that a controlled solvent vapor can soften and reflow. With PostPro, that means the powder-bed nylons PA12 and PA11, the elastomers TPU and TPE, polypropylene with its dedicated agent, industrial FDM materials, and 100+ thermoplastics1 with FA326 on the SF50 and SF100.
