LPKF ProtoPaint LDS adds a laser-activated coating to generative manufactured prototypes in no time. The paint system prepares the plastic parts fabricated using a generative method for true LDS prototyping. The plastic blanks can be produced using various generative techniques:
 
When selecting the plastic one should ensure adequate heat resistance. The paint is cured at oven temperatures of ideally 90°C or a minimum of 70°C with prolonged curing times. The plastic pieces must withstand these temperatures without warping. Manufacturers of plastics prototypes can now choose from a large number of plastics for the above generative techniques with a range of heat resistances.

The temperature resistance of a plastic prototype must further be considered with respect to assembling electronic components to the finished LDS-MID. The paint can’t withstand the fusion temperatures of traditional lead-free or leaded solders. It’s therefore useful to contact electronic components though conductive gluing. This requires the plastic piece to have a heat resistance of at least 100°C, better yet 120°C.
