Taguchi-based optimization of mechanical properties and dimensional accuracy of selective laser-sintered polyamide-12

Studies found that parts produced using selective laser sintering (SLS) exhibit non-uniform surface morphology and lower physical properties. These characteristics are associated with decreased tensile strength and overall performance of polyamide-12 (PA-12) manufactured through conventional SLS. This study aims to ext...

Interactive Effects of Lubricant Type and Sliding Distance on the Tribological Behavior of Aluminium 6061 Against SKD11 Steel

This study investigated the effects of lubricant formulation and sliding distance on the tribological behavior of Aluminum 6061 coupled with SKD11 steel under a constant normal load of 10 N. Sliding distances of 100, 1000, and 5000 m were tested under three lubrication regimes: dry contact, waste cooking oil (WCO)-base...
