R&D group to unlock 3D printing potentials for automotive parts 
In the Austrian-German research project SYMPA, a consortium led by coordinated by the Institute of Aircraft Design (IFB) of the University of Stuttgart is developing new materials, printing methodologies and post-processing technologies for durable Stereolithography (SLA) products using Digital Light Processing (DLP) with a focus on automotive applications.

The project partners believe that the SLA technology has a huge potential to enable the production of customized parts and products specifically designed for customer needs especially in the automotive industry. Thus, SYMPA aims to overcome some of the weaknesses of current SLA materials such as low mechanical properties, low durability and low UV stability. The innovation objectives include the development of a new photosensitive polymer materials with increased long-term thermal and mechanical properties, the fibre reinforcement of the polymer and surface modification technologies to further enhance the environmental resistance of products. All developed technologies will be demonstrated based on real automotive parts considering the requirements on industrial production processes. 

SYMPA is coordinated by the Institute of Aircraft Design (IFB) of the University of Stuttgart and involves partners across the entire value chain of the SLA technology including material specialists, machine producers and research institutes. Examples are chemical company Henkel AG & Co KGaA; Henkel has developed novel high-performance photopolymers with improved mechanical and thermal durability for the SLA technology.

Rapid Shape GmbH offers high speed open 3D printing systems that can be adopted with different process extensions to meet various material or customer requirements and environmental conditions.
