DESCRIPTION
Additive manufacturing (AM) offers a few major benefits to biomedical applications. To improve the knowledge on AM possibilities, Sirris is organizing two different masterclasses. The first will address the technology, materials used and applications, with experts in the matter explaining all relevant aspects.TRANSCRIPT

The future of Additive Manufacturing
• Three different ways of using AM technologies
• Prototyping for visual models or functional parts
• Direct production of parts (light redesign, only validation)
• Direct production of parts redesigned for AM
(no way back to conventional production)

11
Additive Manufacturing Limitations
• Geometrical limitations: • Wall thickness: 0.3 mm – 1.5 mm • Length of internal channels (powder removal) • Max. size: 100 mm 4000 mm.
• Anisotropy (axe Z) for some mechanical properties • Surface quality (layer thickness, orientation) • Support structures for 3D building with some AM techniques.
(generation, building, removal)
• Some understanding of the AM processes are required for
• The designer (dimensioning, resolution, wall thickness)
• The manufacturer (part orientation, support generation, shrinkage factor, warping)

Integration of functions
• The design of a complex part with several local functions (spring effect, damping effect) usually requires the assembly of components in different materials.
• With AM, this is possible in one step with bi-material process like the Connex machine (Objet)

products rather than prototypes
• AM maturity: large range of cost, performance & applications
