A novel preparing method of polymer-coated molybdenum powder was presented. A type of multi-component polymer-coated molybdenum powder was chosen for selective laser sintering. The effect of the process parameters on the part’s characteristics is investigated. Based on our study for dynamic laser sintering process of polymer-coated molybdenum powder, its laser sintering mechanism was reported a...

The micro metal injection moulding (μMIM) is suitable for producing high series of net shaped parts at competitive cost compared with subtractive processes, as dental implants. The μMIM has five main steps: selection of powders and binder, production of feedstocks (mixing), injection moulding, debinding and sintering. The material selected was the 316L steel due to its wide use as biomaterial a...

Nonlinear shrinkage of the metal part during manufacturing by bound deposition, both on ground and under microgravity, is considered. A multi-scale physics-based approach developed to address problem. It spans timescales from atomistic dynamics order nanoseconds full-part hours. This enables estimation key parameters problem, including widths grain boundaries, coefficient surface diffusion, ini...

The reactivity of the ATP-dependent multidrug transporter P-glycoprotein (Pgp) with the conformation-sensitive monoclonal antibody UIC2 is increased in the presence of Pgp transport substrates, ATP-depleting agents, or mutations that reduce the level of nucleotide binding by Pgp. We have investigated the effects of nucleotides and vinblastine, a Pgp transport substrate, on the UIC2 reactivity o...

Powder injection molding of superalloys offer a potential route for the manufacture of small and geometrically complex components for the aircraft engine industry. In this investigation, 625 and 718 alloy powders with an average size below 10 pm were injection molded into tensile test bars which were then sintered in a hydrogen atmosphere at diverse temperatures after debinding. Other 718 alloy...

In this study, we focus on making a double-sided metal plate with an internal structure, such as honeycomb. The stainless steel powder was used in the metal injection molding (MIM) process. The preliminary studies were carried out for the measurement of the viscosity of the stainless steel feedstock and for the prediction of the filling behavior through Computer Aided Engineering (CAE) simulati...
