|Project title||Optical quality control for extrusion 3D printing (Quali3D)|
|Project duration||01.07.2019 – 30.06.2021|
Additive manufacturing is a fast-growing market. Especially for small and medium-sized companies extrusion based additive manufacturing is interesting due to the large number of processable materials and application areas. However, as a supplement to existing manufacturing technologies a nationwide use of extrusion based additive manufacturing is not in progress. Deficits in the knowledge of process qualities and control variables lead to quality problems and a lack of acceptance regarding to the technology. In addition, with today's 3d-printers process errors will not be detected or only after the completion of a part.
The aim of this research project is to assure the additive manufacturing process with optical measuring technology. The inline quality assurance system works layer by layer. The project will contribute to the further industrialization of additive manufacturing.
Publications about the project
Quality assurance methods are a central success factor for the further industrialization of additive manufacturing. This paper presents an approach for an optical inspection system that controls the quality of additive material extrusion layer by layer. The inspection task gets analyzed, hardware components for data acquisition are designed and a first step towards texture-analytical detection of defects is presented.

Quality assurance methods are a central success factor for the further industrialization of additive manufacturing. In the IGF research project "Optical quality inspection for extrusion 3D printing (Quali3D)", a testing system is therefore being developed which monitors the quality of the additive process layer by layer. This should enable a comprehensive evaluation.
