The team of IwF GmbH stands out due to the young professionals, who drive the concept of tool-free production in its further development through curiosity and innovative thinking. Due to the close cooperation with the University of Applied Sciences Aachen, especially with the GoetheLab for Additive Manufacturing and the Aachen Centre for 3D Printing, it is possible to convey and support not only the theory, but above all the practice in an industry-oriented way.

The team focuses on “metal” and “plastics” in additive production. In addition to material and feasibility studies, AM-compatible design and optimization in the process chain of the laser beam melting process are important fields of activity in the metal sector. In addition to process development and customer-related contract research, the plastics group is also responsible for the design, development and optimization of 3D printers.

Prof. Dr.-Ing. Andreas Gebhardt

Partner and Managing Director

The university professor Prof. Dr.-Ing Andreas Gebhardt will be happy to advise you in the area of research and development. He is a leader in the research field of additive manufacturing processes and draws on many years of experience in research, teaching and practice.

After studying mechanical engineering at RWTH Aachen University (Rheinisch Westfälische Technische Hochschule Aachen), 1973-1978, and obtaining his doctorate “summa cum laude” at RWTH Aachen University (1986), he was Managing Director of Erasmus & Willms Motorentechnik GmbH & Co KG in Aachen from 1986-1992 and, overlapping from 1991, also Managing Director of LASER Bearbeitungs- und Beratungszentrum NRW GmbH, LBBZ-NRW, Aachen as part of a research project on laser hardening of crankshafts.

In this position, he began to deal with what was then known as rapid prototyping, the generative manufacturing processes. In the course of research and development in this new field, 147 relevant publications were published in Germany and abroad up to the year 2000, including the Hanser reference book “Additive Manufacturing Processes: Additive Manufacturing and 3D Printing for Prototyping – Tooling – Production” (5th edition 2016, 736 pages) and the more compact version “3D Printing: Basics and Applications of Additive Manufacturing (AM) (2nd edition 2016, 234 pages).

Since 1996 he has been managing director of CP-Centrum für Prototypenbau GmbH, Erkelenz, a service provider for generatively manufactured prototypes with 50 employees, which was founded from LBBZ-NRW GmbH. In the course of projects for the introduction of generative processes, e.g. in Bangalore, India, he was appointed by UNIDO, the United Nations Industrial Development Organization, as an “International Expert on Rapid Prototyping”. In 2000, he was appointed professor for “High-performance processes in manufacturing technology and additive manufacturing” at the University of Applied Sciences Aachen.

Dr.-Ing. Julia Kessler

Partner and Managing Director

Dr. Julia Kessler studied at the University of Applied Sciences in Aachen and holds a Bachelor’s degree in Biomedical Engineering and a Master’s degree in Product Development. From 2012 to 2017 she worked as a research assistant in the research group “GoetheLab for Additive” Manufacturing at the University of Applied Sciences Aachen. Since 2016 she has headed the team of the GoetheLab, which deals with the additive production of metals, plastics and ceramics. Julia Kessler has been intensively involved in the conception of a course of study for digital dental technology and led a research project on jaw augmentation. Together with Laura Thurn, she initiated and implemented the “FabBus” project, a mobile 3D printing laboratory. Julia Kessler and her colleague Laura Thurn also jointly implemented an online module “Additive manufacturing/3D printing”. In the context of her doctorate, Ms. Kessler worked on the design optimization and additive production of bionic lattice structures made of titanium and stainless steel, as well as new fields of application for these construction elements. She successfully completed her doctorate in October 2017. Julia Kessler took over the management of IwF GmbH in 2015 as a sideline and has been full-time since October 2017.
