Internship: transient CFD Modelling of PEEK deposition by a 3D printer
Full Time, Enschede The Netherlands
The goal of the assignment is to improve the controlled deposition of material during starts/stops.
What to do?
To gain more insight into the deposition of a material by a 3D printer, a 3D Computational Fluid Dynamics (CFD) model has to be built. The goal of the assignment is to improve the controlled deposition of material during starts/stops. More specifically:
- Understanding of dynamics flow behavior inside and outside the nozzle
- What is the transfer function from feeder motion to material flow out of the nozzle?
- With which accuracy can the flow be predicted and thus controlled?
- Understanding of extrudate temperature in dynamic situations
- What is the influence of feed rate changes on the temperature of the material that flows out of the nozzle?
- If significant, how can we reduce variations in extrudate temperature?
The internship is a combination of fluid–, thermal– & control dynamics.
Responsibilities and duties
- The CFD model should be simulated with Ansys. The intern should determine how the model is built and which effects and parameters should be taken into
- Tests should be carried out on the test machine to validate the model;
- Communicate with relevant stakeholders to pursue the goal.
- Studying to get a master’s degree in Applied Physics, Mechanical Engineering or similar;
- Familiar with Ansys is a benefit;
- Affinity with 3D printing is a benefit;
- Fluent command of both written and spoken English;
- You’re creative, driven, proactive, pragmatic, communicative and a team player. You enjoy working together with various disciplines within the organization where communication with colleagues is non–hierarchical and direct.
