Material Characterization of AISI 316L Flexure Pivot Bearings Fabricated by Additive Manufacturing

A Line-focus Transducer System for Property Characterization of Materials Fabricated by Additive Manufacturing

In vivo XCT bone characterization of lattice structured implants fabricated by additive manufacturing

Several cylindrical specimens and dental implants, presenting diagonal lattice structures with different cell sizes (600, 900 and 1200 μm) were additively manufactured by selective laser melting process. Then they were implanted for two months in a sheep. After removal, they were studied by Archimedes' method as well as X-ray computed tomography in order to assess the penetration of bone into t...

Friction-corrosion of AISI 316L/bone cement and AISI 316L/PMMA contacts : ionic strength effect on tribological behaviour

Wear phenomena understanding of implants is a challenge: friction-corrosion of biomaterials, which constitute orthopaedic implants, is a significant issue concerning the aseptic loosening. This work aims at studying AISI 316L/bone cement friction which is a tribological problem related to hip joint cemented prostheses. This study focuses on the ionic strength effect on the tribological behaviou...

Mechanical Design of Viscoelastic Parts Fabricated Using Additive Manufacturing Technologies

Mechanical design of viscoelastic parts fabricated using additive manufacturing technologies are under consideration. Such a design is of great importance for obtaining final products with desired shape and strength which are determined by their stress-strain state. Mathematical model of model of viscoelastic solid which grows due to the process of additive manufacturing is proposed. Complete s...

Sustainability Characterization for Additive Manufacturing

Additive manufacturing (AM) has the potential to create geometrically complex parts that require a high degree of customization, using less material and producing less waste. Recent studies have shown that AM can be an economically viable option for use by the industry, yet there are some inherent challenges associated with AM for wider acceptance. The lack of standards in AM impedes its use fo...
