Why dyeing?
Colour penetrates the surface layer
The colour soaks into the surface – a scratch does not immediately reveal the grey.
Uniform look
Consistent colour even in channels and undercuts.
Close to series look
Dyed parts look like finished products.
Combinable
Even higher quality with blasting or chemical smoothing.
How it works
- Step 1
Cleaning
The part is depowdered and cleaned.
- Step 2
Preparation
If necessary, the surface is blasted.
- Step 3
Dyeing
The part is evenly dyed in a warm dye bath.
- Step 4
Inspection
Rinsing, drying and visual inspection.
Which processes and materials?
| Process / material | Suitability | Note |
|---|---|---|
| SLS · PA12 / PA11 | very good | porous surface absorbs colour well |
| SLS · TPU | good | shade depends on material |
| FDM | via the filament | we choose the colour directly with the material |
| SLA | limited | better to paint or use coloured resin |
Where it pays off
Notes
Why dye instead of paint?
Paint sits on the surface and can chip. In dip dyeing, the colour soaks into the porous surface layer of SLS and MJF parts – a scratch does not immediately reveal the grey underneath. The colour also reaches channels and undercuts evenly, and dimensions practically do not change.
Standard is a deep black; we offer other colours on request. Combined with blasting or chemical smoothing, dyed parts look like series products. For FDM we choose the colour directly via the filament, for SLA via coloured resin or painting.
Suitability
| SLS · MJF | porous surface, absorbs colour well |
|---|---|
| FDM | colour directly via the filament |
| SLA | rather paint or coloured resin |
| Standard colour | black, others on request |
FAQ about dyeing
Which colours are possible?
Black is standard. We offer other shades on request – just ask us.
Is the colour permanent?
Yes, it penetrates the surface layer. Under strong UV exposure it may fade slightly over the years.
Can FDM parts be dyed?
With FDM we choose the colour directly via the filament – that is simpler and more uniform.
