The popularity of additive manufacturing in the medical device manufacturing industry is growing thanks to the ability to print solid substrate and lattice structure for implant fixation in a single step. Printing a lattice structure is not only a matter of design but it also requires the ability to process the foam-like structure in a way that make it usable in the human body. Cleaning, in this specific case, removes loose particles and/or contaminants from such structures. To achieve this objective, Eurocoating developed a mechanical and dry step to remove the majority of the loose particles without adding any additional substance to the lattice structure. Following steps based on chemical etching of the titanium surface on a lattice structure can be used to remove the remaining particles and to modify the structures’ surfaces to enhance osteoconductivity. In cases where lubricants used in machining must be removed, we are seeing promising results in developing a proper cleaning step with specific detergents, which avoids any detectable residual in the foam but is capable of completely removing the contaminants.

Attendee Takeaways

  1. Cleaning of porous structure where loosely held particles are removed
  2. Recommendations on establishing and maintaining a residue removal process
