Internship: transient CFD Modelling of PEEK deposition by a 3D printer

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
    account;
  • Tests should be carried out on the test machine to validate the model;
  • Communicate with relevant stakeholders to pursue the goal.

Expectations

  • 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 nonhierarchical and direct.

Spreekt High Tech jou aan? En een omgeving waarin multidisciplinair inzicht vanzelfsprekend is? Grijp jij zo’n technische uitdaging met beide handen aan en wil jij samen met jouw collega’s aan de slag om hiervoor concepten te ontwikkelen? Grijp dan nu je kans en ga aan de slag bij Bond3D en lever een belangrijke bijdrage aan de ontwikkeling van deze revolutionaire printer.

Bond3D heeft een revolutionaire print-techniek bedacht om onderdelen gemaakt van high performance polymeren te produceren door middel van additive manufacturing. De producten hebben dezelfde eigenschappen als producten die momenteel worden geproduceerd met conventionele technieken. Sinds de oprichting in 2014 is Bond3D bezig met de ontwikkeling van de 3D-printer om de innovatieve concepten in de praktijk te brengen. De nieuwe generatie printers die nu in ontwikkeling is, kan de onderdelen snel, in hoge kwaliteit en reproduceerbaar printen.
