Selective Laser Sintering (SLS) is a powder-bed Additive Manufacturing process that has a large amount of potential for future growth. Historically SLS has been limited to a narrow selection of polymers, although there have been recent advances in working with composite powders, such as Alumide. One of the biggest limitations to developing new materials for sintering is the elevated risk involved...
Polyamide 6 (PA6) nanocomposites filled with 2, 4, 6, 8 wt% hydroxyapatite nanorods (nHA) were compounded in Brabender extruder followed by injection molding. The effect of nHA additions on the structure, mechanical properties and in vitro bioactivities of such nanocomposties were investigated. XRD patterns showed that PA6 crystallized exclusively in the ??-form by adding nHA. DSC analysis revealed...
A bioactive and biodegradable composite containing hydroxyapatite (HA) and polyhydroxybutyrate (PHB) was developed for bone tissue repair. A manufacturing process, which consisted of compounding, pelletising, drying, and injection moulding, was established for producing the composite. The HA/PHB composite containing 10, 20, 30 and 40% by volume of particulate HA was successfully made. The distribution...
