DTU Mechanical Engineering has an open PhD position in the field of Light Engines for Vat Photopolymerisation Systems. The PhD project which is anchored at the Section for Manufacturing Engineering, and in close collaboration with the Image Analysis Section at DTU Compute, aim to advance image mask generation and light projection systems in vat photopolymerisation by research into next generation image mask projection systems and their application in said field.

Responsibilities and tasks
Vat photopolymerisation based Additive Manufacturing (AM) allows for the direct manufacture of the highest fidelity of geometries with intricate and detailed features and highly complex components. As such, vat photopolymerisation is already an important driver in the larger trend of digitalization of the manufacturing industry, the fourth industrial revolution colloquially known as Industry 4.0 (I4.0). The Manufacturing Academy of Denmark (MADE) is a large-scale research framework in its third instalment, known as MADE FAST. It actively drives the digital technologies of tomorrow into the Danish industry. It is within this research framework that the PhD position is anchored. 

In tightknit collaboration of the Danish industry, the Technical University of Denmark has for a decade been advancing the very core of the technologies for vat photopolymerisation. This has been done through a decomposition of the technology into its constituents and through targeted research and development of these systems to build next generation machines that push the manufacturing rate, the manufacturing cost, the component quality and the material performance in order to make vat photopolymerisation evermore competitive against conventional manufacturing methods. 

This PhD project intent to execute such a break-down of the sub-system that is the light engine of mask projection based vat photopolymersiation systems. This is done in effort to be able to draft out and design and subsequently build test and production ready a next gen light projection unit that can push the frontier of build rate, component fidelity and build envelope. 

The scientific goal of this PhD project can be broken down to three consecutive tasks that are; to expand the fundamental understanding of the cause- and effect of having access to low level control of a light projection unit. This activity sets requirements for the candidate in the understanding of vat photopolymerisation. Second, to devise and validate the performance of a next generation light engine. This sets requirements to understanding of construction, electronics, computer science and optical systems. 

The third consecutive goal will be, to reiterate the light engine, with respect to design for manufacturing such that a (near) manufacturing ready light engine has been realised by end of project.

The candidate’s skills are therefore:

  • M.Sc. in Optics, Mechanical Engineering, Mechatronics, Electrical Engineering   or similar.
  • Collaborative skills; ability to work independently, to plan and carry out complicated tasks, and to be a part of a large, dynamic group 
  • Excellent English Proficiencies, written and spoken

The candidate’s knowledge is therefore within multiple of the following fields:

  • Knowledge image mask projection systems.
  • Knowledge DMD image generation devices and their control.
  • Knowledge within AM processes and in particular in vat photopolymerisation.
  • Knowledge of electronics, mechatronics and of machine construction and design.
  • Knowledge of programming, in particular in computer graphics, embedded programming and in hardware driver programming. Some knowledge of scientific computing is preferred
Candidates should have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree. 

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.   

The assessment of the applicants will be made by Senior Researcher David Bue Pedersen.
