The call for customised developments and requirements has reached ViscoTec through numerous customers. An extension of the ViscoTec 3D portfolio was developed based upon market requirements: The vipro-HEAD color ink delivery system.

vipro-HEAD colour ink delivery system expands ViscoTec 3D portfolio
Individual design of 3D printed components is made possible with the ink delivery system. Not only can single-coloured or transparent components be created, but also a wide range of colours and designs can be chosen – for the end customer, particularly in the consumer sector.
The proven ViscoTec endless piston principle inside the ink delivery system guarantees a precise supply of ink of up to 1-3% to the material (e.g. silicone). The required, and adjusted ink quantity is continuously maintained for homogeneous colour lines in the component. The system has a modular design. In the event of an ink change, print heads, that can be purchased individually, ensure complete flexibility in the process. An individual adjustment, for example use of other colours or other colour concentrations, can be done very quickly after a simple switch of the print heads.
Existing colour pigments from the injection moulding sector can be used for the ink delivery system. These inks have already proven themselves in numerous applications.
The purely volumetric dosing of printing materials and inks in the ViscoTec 3D print heads is perfect for highly viscous materials. These are handled precisely, ensuring complete printing process reliability. The colour pigments are reliably mixed with the main material in the static mixing tube. This guarantees an optimal design of the finished components.
Setting the automatic suck-back function at the end of a printing process does not have any negative impact, such as color fluctuations in in the component. On the contrary, the suck-back feature ensures a clean dosing process and prevents dripping or stringing of the material.
