Title: TWIN Project — Transformation of complex product development processes into knowledge-based services for generative manufacturing

Project duration: October 2019 – April 2023

Research Area: Manufacturing

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
• Monitor printing process
• 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
