Roughness of as-printed 3D parts is limiting the real breakthrough of Additive Manufacturing. Post processing technologies consist out of subtractive techniques such as grinding or sanding, or out of additive techniques such as coating.

In this presentation Ultrasonic Spray Coating as an additive post processing technologie is described to first of all reduce the roughness of Selective Laser Sintered substrates down to less than 2 micrometer and further, functional formulations consisting out of a polymer and nanoparticles is prepared to not only reduce the roughness but also add functionalities to the surface of the 3D substrate such as scratch resistance or superhydrophobicity.

3D Printed Electronics will ultimately enable and drive the merging of mechanical and electrical disciplines. Just as desktop 3D printers combined with the many peripheral software components empowers everyday, non-engineers to modify their world to their liking, and realize their innate creativity without formal engineering training, 3D printed electronics will not only open the doors, but will completely remove the roof and enable one of the most impactful forms of creativity and innovation that the world has ever seen.

Metrology for quality management of printed conductors

Richard Koops

by Richard Koops, VSL Dutch Metrology Institute

First time right production is key in advanced manufacturing processes since usually only relatively small volumes are manufactured. In-line and in-process metrology is required to measure critical to quality process and product parameters. Ultimately, these measurements enable feedback control when the parameters are running out of tolerance.

Within the Hyb-Man project, technologies are being developed for embedded electronics and printed interconnects. Since the functionality of the interconnects determines whether the final product will be accepted or has to be rejected, metrology has been developed to inspect the quality of conducting printed tracks.

3D Printing of Multi-Functional Structures

3D printing has generally been relegated to fabricating conceptual models and prototypes; however, increasingly, research is now focusing on fabricating functional end-use products.

As patents for 3D printing expire, new low cost desktop systems are being adopted more widely and this trend is leading to products being fabricated locally. However, currently the technology is limited in the number of materials used in fabrication and consequently is confined to fabricating simple static structures.

For additively manufactured products to be economically meaningful, additional functionalities are required to be incorporated in terms of electronic, electromechanical, electromagnetic, thermodynamic, chemical and optical content.

A lot of potential for 3D printed electronics in the automotive field

3D printing is affecting the way engineers design in the automotive
industry. The technology is already used in the industry, currently
mostly for plastic and metal spare parts. Additive manufacturing has
opened the door for newer designs, safer products, shorter lead times
and lower costs. Moreover, it will be an enabler for the automotive industry to adapt towards the new smart mobility requirements.
