Dyeing 3D prints is a new area we are currently working on.The ultrasound supports the adhesion of the ink pigments on the surface of the printed media. According tests with EOS- and HP-Prints are very satisfying.  (see examples).

To dye 3D-parts weoffer three system types:
Solo-Systems with just one basin for dyeing
Duo-Systems with two basins (dyeing and rinsing)
Trio-Systems with three basins (dyeing, rinsing and drying)
(alternatively with two basins for different dyes and one rinsing basin in the centre)

  

We achieved excellent dyeing results using the GTC dyeing liquids,  manufactured by a french company TCN, which are ideally suited for dyeing 3D parts. Suitabele materials are Polyamide, Polyurethane, Acrylic, Resin, Carbon Fiber, Polyester, ABS. https://www.techniques-chimiques-nouvelles.com/en/additive-manufacturing/

  • Dyeing time approx 1 to 10 minutes (depending on material)

  • Cost of dyeing liquids: approx. € 25,- (GTC) – € 37,- (GTD) per Liter
  • Temperature 60 – 85° C
  • Testet with EOS- & HP-Prints
  • Basket Volume from 20 Liter
  • Multiple usage of dyeing liquid
  • System cost from approx. € 4.800,-  (20-Liter-System)
