Title: TWIN Project — Transformation of complex product development processes into knowledge-based services for generative manufacturing
Project duration: October 2019 – April 2023
Lead: Prof. Erhard Rahm
Team Members: Benjamin Uhrich
Partners: InfAI e.V., Fraunhofer IWS, LASERVORM GmbH, Siemens AG, CPT Präzisionstechnik GmbH, quapona technologies GmbH, Leipzig University
Research Area: Manufacturing
TWIN
The focus of the TWIN project is the development process for the production of prototypes using laser powder cladding (LPA) from the field of generative manufacturing (GM). The goal is to increase automation, quality, reliability, and data availability in generative manufacturing, using the LPA process as an example, through automated data processing and machine learning methods. This holistic approach lays the foundation for new intelligent services.
Aims
- Reduce number of erroneous printed parts
- Predictive maintenance of LPA machines
Practical example created during the project
- Working Prototype for analysing a 3D print in laser powder bed fusion (LPBF)
- Predictive maintenance model for LPA
- End-to-End processing pipelines of images and time series data
Technology
- Kubernetes, Docker, Kafka, MQTT
- Python, PyTorch, Typescript, Angular
