Beschreibung

Background:
Laser-Directed Energy Deposition (DED-LB/M) is an Additive Manufacturing (AM) process in which metal powder is melted by a laser and deposited layer by layer to create complex geometries. This technology enables the efficient and material-saving production of various components. However, optimal process parameters are crucial to ensure a high-quality and defect-free deposition.

Aim:
This work aims to determine a process window for DED-LB/M based on a Design of Experiments (DoE) study. The study will focus on a nickel-based alloy with a similar composition to Inconel 625. By systematically varying critical process parameters, including laser power, feed rate, and powder flow rate optimized parameters will be determined.

Tasks:

  • Research on the state of the art in DED-LB/M and DoE-based parameter studies
  • Design of an experimental plan
  • Experimental execution of the parameter study
  • Evaluation according to determined quality criteria
  • Derivation of a process window
Voraussetzungen
  • Interest in laser-based AM, experimental work and structured data analysis
  • Initiative and independent working style
  • Good German or English skills
  • Basic knowledge of DoE and metallographic analysis is an advantage
