Selective laser sintering (SLS) enables the fabrication of complex geometries with the intricate and controllable internal architecture required in the field of tissue engineering. In this study hydroxyapatite and poly-caprolactone, considered suitable for hard tissue engineering purposes, were used in a weight ratio of 30:70. The quality of the fabricated parts is influenced by various process...

Scaffolds of PDLLA were produced to be implemented in maxilofacial surgeries inducing bone repair and regeneration. To prepare these scaffolds, bioglass (BG58S) was synthesized by sol-gel method, in order to be applied as osteoconductive dispersed particles in PDLLA matrix. Once presenting greater facility on parts fabrication, this polymeric matrix enables complex geometries production besides...

Selective laser sintering (SLS), as a kind of additive manufacturing technology, which uses beam to scan and heat powder material layer by form parts (models), is widely used in the field casting, mainly for preparing casting coated sand cores, investment patterns, etc. The SLS technique facilitates rapid shortens production periods eliminating mold preparation. In this study, we reached conclu...

There have been a variety of efforts demonstrating the use of solid freeform fabrication (SFF) for prosthetic socket fabrication though there has been little effort in leveraging the strengths of the technology. SFF encompasses a class of technologies that can create three dimensional objects directly from a geometric database without specific tooling or human intervention. A real strength of S...

The aim of this study is to investigate the possibility of a freeform fabrication of porous ceramic parts through selective laser sintering (SLS). SLS was proposed to manufacture ceramic green parts because this additive manufacturing technique can be used to fabricate three-dimensional objects directly without a mold, and the technique has the capability of generating porous ceramics with cont...

Quantifying faults in manufacturing processes is a crucial concern, particularly in new manufacturing processes where continual product improvement is desired. We present an approach to incrementally diagnose fault patterns on surfaces of product components. Contemporary experimental and surface-analysis techniques are adapted at each step of the approach. Specifically, a maturing layeredmanufa...
