///PhD: Thermal and microstructural simulation of laser-based large scale additive manufacturing – University of Twente, Enschede (the Netherlands)

Introduction

The Chair of Laser Processing in the Faculty of Engineering Technology of the University of Twente (The Netherlands) has an opening for a PhD candidate in the research area of laser-based Large Scale Additive Manufacturing. At the Chair we study the fundamental physical phenomena occurring during laser-material interaction, in order to optimize laser-material processing for controlled laser-based additive manufacturing (AM). As such we take part in a nation-wide research effort on additive manufacturing. Will you be a member of this research team involving 4 Dutch technical universities and 20 industrial partners?

Function

The project “Additive Manufacturing for Extra Large Metal Components” (AiM2XL) aims at the production of large-scale (~1 to >10 m) additively manufactured metallic components for maritime applications. The aim of this project is to predict the microstructure and composition of laser-based AM for the design of tailored properties of metallic components.

AM processing conditions create spatial and temporal temperature distributions in the deposit and affect the solidification and metallurgical phenomena which determine the microstructure. Additionally, the chemical composition of the deposit may affect the microstructure phases and residual stresses in the material. To predict the relationship between processing conditions (laser parameters and material parameters), resulting microstructures and chemical composition in the material, the temperature profiles need to be established with a high degree of accuracy. It is therefore essential to model the transient spatial temperature distribution, to generate strategies to tailor properties in 3D constructs on demand, via microstructure and/or compositional control.

You will develop numerical models for efficient simulation of (temporal and spatial) laser-induced temperature profiles and microstructural evolution during and after production;

To that end, you will:

  • choose appropriate advanced numerical techniques and optimize them for simulation of additive manufacturing;
  • validate your simulation models by measurements on actually produced samples;
  • You will closely collaborate with your research-team colleagues at University of Twente, at the universities in Delft, Eindhoven and Groningen, as well as with the consortium of industrial partners;
  • You will mentor BSc and MSc students, who do graduation projects in support of your research;
  • You will finish your research with a PhD thesis.

Requirements

  • You hold a MSc degree in materials science, mechanical engineering, applied physics, or a closely related discipline, with a strong background in metallurgy.
  • You have excellent skills and experience in application finite element methods and programming for numerical simulations in thermodynamics and microstructures;
  • You have a strong analytical mind and an eye for detail to develop fundamentally robust algorithms, as well as a critical attitude towards assessment of simulation and experimental results;
  • You are aware of:
  1. analysis technologies/techniques such as SEM, EDX, AFM, confocal microscopy, etc;
  2. and preferably, fundamental aspects of high-power laser-material processing, such as laser cladding,
  • You like to present your results to colleagues, industrial partners and at international conferences;

Offer

We offer a very challenging fulltime position for four years in an inspiring multidisciplinary and international environment. The university offers a dynamic ecosystem with enthusiastic colleagues in which internationalization is an important part of the strategic agenda.

  • We provide excellent mentorship and a stimulating research environment with excellent facilities;
  • You will be given the opportunity to acquire teaching experience;
  • You are offered a professional and personal development program within Graduate School Twente;
  • A starting salary of € 2.222 in the first year and a salary of € 2.840 in the fourth year gross per month;
  • A holiday allowance of 8% of the gross annual salary and a year-end bonus of 8.3%;
  • A solid pension scheme;
  • Minimum of 29 holidays per year in case of full-time employment.
