Freeform PIM is the use of 3D-printed mould inserts that provide the part geometry in the injection moulding step. The feedstock-filled insert will be ejected after the injection moulding step, and the printed part then chemically dissolved to release the green part. Following this additional insert-removal step, the original processing route continues with the green part.

Project activities (to be tuned via the survey, see below):

  • Testing of feasible features (dimensions, tolerances, quality, etc.)
  • Translation of print part properties to PIM part properties
  • Implementation of process chain for several feedstocks, e.g. regarding green strength and compatibility with the chemical removal process of printed structures (depending on the number of participants and budget)
  • Deduction of construction guidelines for print parts
  • Development of an improved strategy for a base mould concept and possibly implementation of the mould concept (depending on the number of participants and their feedback)
  • Implementation of moulding simulation for more efficient insert part production and shortening of setup time for injection moulding runs
