The problem

While an increasing range of possibilities for 3D-printed medical implants is implied by the latest 3D design and engineering methods, they are far from unlocking the full potential offered by this new production route, failing to address main requirements on the internal structure of implants, whilst:

  • maintaining structural stability
  • easy access for cleaning
  • maximum surface area for osseointegration
  • internal coatings with slowly degrading substances
  • open-porous structures allowing high fluid-flow
  • fast vascularization and bone growth.

Also, the impact of suboptimal design on the additive manufacturing of titanium implants limits their competitiveness toward traditionally produced implants:

  • tedious removal of support structures
  • non-controllable surface texture
  • residues from mechanical removal
  • and shape sacrifices to avoid closed powder pockets

Our Technology in Medical Implants

As minimal surfaces, ADMS exhibit a smooth curvature distribution and are thus exceptionally stable using the minimal amount of material. Load-case adaptable, locally configurable ADMS parameters include:

  • wall thickness
  • channel diameter
  • porosity or structural density.

As minimal surfaces, ADMS exhibit a smooth curvature distribution and are thus exceptionally stable using the minimal amount of material.

Our testing concluded the following characteristics:

  • No collapsing effect
  • Modifiable strength
  • Modifiable elastic gradient (stiffness)
  • Predictable, foam-like characteristics
