3. DECORATION DIGITAL PRINTED DECORATION
10
DIGITAL PRINTED DECORATION
small series down to lot size one
bigger series with individualized or personalized features
(mass customizing)
complex patterns and/or multilayer structures (e.g.
inhomogeneous or graded structures)
some bioinks require non impact printing
ultrafine structures down to a
size of single nano particle
Where can digital printing be interesting compared to
conventional methods?

4. 3D SURFACES DTS - DIRECT-TO-SHAPE
16
DIRECT TO SHAPE
Research program starting in January 2016 for 4 years
Digital printing on the surface of 3-dimentional objects:
DT
17
• Graphical images (color, varnish, …)
• Decoration (metallic, optic, haptic, …)
• Functionalization (surface
properties, luminescence, …
intelligence)
Small size objects
jewelry, watches, etc.
Mid size objects
balls, bottles, etc.
Big size objects cars, aircrafts, etc.
CHALLENGES
Where are the additional challenges of this program?
18
• Jetting at variable and higher distances
• More than one color or functional fluid, registration issues
are even more challenging on curved surfaces
• Image distortion
• High print accuracy on the trajectory (object or print system
handling)
• Substrate properties (adhesion, …)
• …
