Chemical smoothing

The so-called PostPro3D process (PP3D for short) smoothes the surfaces of the components by a chemical treatment and allows a similar appearance as the injection molding process.

Chemical smoothing is used to straighten, seal and improve parts in their mechanical properties, as the notch effect is reduced by the smoothing of the layer tracks.

The surface closes, the components are waterproof and insensitive to dirt, which colored parts are even longer lasting.

The process is applicable to both colored and uncoloured components and can be combined with other finishing processes, as well as for the following materials and manufacturing processes:

Selective Laser Sintering (SLS), Multi-Jet Fusion (MJF), High Speed Sintering (HSS)
- Polyamides 6, 11 and 12
- Fire retardant polyamides
- filled polyamides with carbon, glass or aluminum
- TPU: thermoplastic elastomers, such as polyurethane

Fused Filament Fabrication (FFF/FDM)
- PLA synthetic polymers, polylactic acid
- PMMA: polymethylmethacrylate, a transparent nylon

ULTEM: Resin for high temperatures (liquid)

The organic solvent used for this process is not flammable and not explosive. It is slightly toxic during the process. The parts, however, are completely free of chemicals. For biocompatible materials, the properties are retained, e.g. in medical products.
