Additive manufacturing of polymer parts
Miniatur-Eiffelturm, Bild: LZH

The LZH offers consulting, feasibility studies and process development for the additive manufacturing of polymer parts. With micro stereo lithography, 3D parts can be manufactured with a resolution of > 5 µm. An aerosol jet process enables multi-material manufacturing processes on uneven surfaces, too.


3D printing is a hot topic. The challenges are special materials, high resolutions, short process times and multi-material printing. 3D parts can be manufactured using UV laser polymerization.

Here, micro stereolithography is a bath-based, layer-by-layer technique. However, the primary materials can also be sprayed on with an aerosol jet and then be hardened. In this case, the application is not limited to even surfaces, and more than one material can be used. 

The Laser Micromachining Group evaluates the general feasibility of additively manufactured polymer parts, and offers support for the following issues and tasks:

  • Suitability of different additive polymer-based manufacturing techniques for your application
  • Process development and optimization
  • Process-related constructional adaptation of the part
  • Evaluation of suitable materials
  • Suitability of laser beam sources, system components and designs
  • Minimization of the process time and costs

This service is, among others, used in the following areas:

Manufacturing processes:

  • Polymerization

Material groups:

  • Plastics

Consulting, development and contract research:

  • Feasibility studies
  • Process and system development
  • Technology consulting and transfer
