When you need it fast: LPKF ProtoPaint LDS adds a laseractivable coating to generatively fabricated prototypes in no time. In the process the paint system prepares e.g. stereolithography components (STL) for true LDS prototyping.
The paint comes as a dual component with basecoat and curing agent. In just a few steps parts become LDS compatible. Full in-house prototyping also requires a LPKF Fusion3D 1000 laser structurer and a lab-compatible metallization solution.
In practice a 3D plastic piece is coated with LPKF paint. The coat thickness ranges anywhere from 30 to 40 μm, and for an adequately uniform coat two to three coats have shown to be ideal. If necessary, for example when working with large components, the pieces may also be painted in sections.
A laser structurer such as the LPKF Fusion3D 1000
then activates the special additives in the paint. A pilot laser aids in setting up the laser system to virtually preposition the layout on the component. LPKF has developed a standardized process for currentless metallization of the component, the last step in the process.
