Multimaterial Inkjet Printing for Radar Waveguide Antennas

In this presentation, the printed waveguide antennas investigated in the TINKER project are considered from both a technical and an economic point of view. The printed antennas have high potential to reduce production costs and weight as well as to increase functional integration.

A presentation by Bernhard Polzinger, Research Engineer at Robert Bosch GmbH


Question 1: What drives you?
I see great potential in printed multimaterial components to produce more complex products, miniaturize components and reduce manufacturing costs. My goal: the mass production of printed components.

Question 2: Why should the delegate attend your presentation?
TINKER is a fascinating project for the use of a multi-material 3D inkjet printing technology. But what are the technical and economic advantages? Find out.

Question 3: What emerging technologies/trends do you see as having the greatest potential in the short and long run?
Digital printing technologies that can handle higher viscosity materials and achieve higher resolution at the same production speed. There are candidates that could make this possible, such as LIFT technology.

Question 4: What kind of impact do you expect them to have?
With these technologies and materials, more complex components can be produced at lower cost. In addition, a greater variety of variants is possible at almost the same cost. Furthermore, development times and costs will be reduced. In the end, this makes it possible to manufacture more customized products.

Question 5: What are the barriers that might stand in the way?
Better print heads, better materials and in the end developers who are open to new technologies.
