Increasing resource efficiency of aviation by innovative materials and bionic design for metal components made by additive manufacturing

Additive Manufacturing allows for unconventional design, for weight savings, for functional integrations and efficient production for small lot sizes. To move from simple polymer parts such as brackets to highly functional structural metal components, the productivity of the LB-PBF can be increased while making it more robust with Laser Beam Shaping.

The combination of innovative materials, bionic design and high quality assurance aims to enable the qualification of components more efficiently.

A presentation by Ina Ludwig, Business Development Manager Aerospace at Fraunhofer Research Institution for Additive Manufacturing Technologies IAPT.


Question 1: What drives you?
Additive manufacturing offers an ideal complement to existing technologies. Aerospace in particular can benefit from functional integration, bionic designs and weight savings. Thereby, AM will contribute to resource-efficient and climate-friendly aerospace.

Question 2: Why should the delegate attend your presentation?
Anyone who wants to know how to take the step towards productive and quality-assured production with LB-PBF will learn exciting approaches here.

Question 3: What emerging technologies/trends do you see as having the greatest potential in the short and long run?
LB-PBF will continue gaining importance for aerospace. DED for large structural components will enter new dimensions with the processing of aluminium and titanium. Small precision parts can be accurately produced with Binder Jetting.

Question 4: What kind of impact do you expect them to have?
I think that the first step is to produce more non-critical components in order to gain more experience and safety. . In the long term, these will contribute to more efficient and climate-friendly aerospace.

Question 5: What are the barriers that might stand in the way?
The biggest barriers are quality assurance and thus the qualification and subsequent certification of components and processes. These steps are currently so expensive that it is difficult to identify profitable business cases. In addition, the topic of post-processing offers high potential to meet the requirements from aerospace.

About Ina Ludwig
In 2017 Ina Ludwig finished her studies Industrial Engineering at the University of Duisburg-Essen with a special focus on mechanical engineering and product engineering. Since 2015 Ina Ludwig is active in Additive Manufacturing. She started at Airbus Group Innovations in Munich with investigations of different powder grades and stepped into the metal powder characterization.

After that she worked in a research project at the University Duisburg-Essen for metal powder aging. In another project at the University of Applied Sciences and Arts Northwestern Switzerland in Basel Ina Ludwig investigated the implementation of Laser Sintering Printer in a clinical environment and dealt with the combination of Additive Manufacturing, medical law, risk management and medical technology.

2018 she started working at the Fraunhofer research institution for additive production technologies IAPT and forces the research and development of metal powder handling systems especially for the powder bed based processes. At the end of 2019 she took over the position of business development manager for aerospace to strengthen and drive forward Fraunhofer activities with companies and research institutions in the aerospace field.
