PEL’s 3D Surface Printer (3DSP)
The PEL 3DSP is the result of our expertise in adapting print methods and materials. We have created our own platform for functional material printing of viscous conductive inks on flat and 3D objects.
We have always found that screen printing is the default choice for printed electronics because it allows a thick layer of viscous ink to be deposited. That thick layer of high metal content ink gives good conductivity. However, we wish to use digital deposition – so perhaps we want to use Inkjet. The problem with inkjet is simple: the ink does not have high metal loading so the traces are thin in height and therefore not low resistance.
This platform coupled with (non inkjet) piezo jet heads allows the deposition of high viscosity inks using a digitally controlled multi-axis platform. essentially allowing the digital deposition of “screenprint-like” inks.
If you are interested to know more about the system, please contact us.
There are many advantages to printing directly onto physical objects in certain circumstances. The construction can be much more robust in terms of bonding to the object, high temperature environments, etc.

Most of the 3D objects onto which we print are subject to NDA – so they cannot be shown. The principle is the same, but with more axes in motion.
