Our keynote lecture will be given by Dr. Steven Stanhope, director of the Physical Disabilities Branch at the National Institutes of Health. Dr. Stanhope will discuss findings from a series of research projects related to customization and selective laser sintering construction of passive dynamic ankle-foot orthoses to meet a patient’s individual needs and the biomechanical basis for adapted co...

Selective Laser Sintering has been recently proposed as a feasible engineering technique for manufacturing of customized ankle-foot orthoses (AFOs). Development of computer-aided design (CAD) models and virtual evaluation of the orthotic devices are important steps in the engineering design process. This paper will describe a method for accurate characterization of SLS Nylon 12 mechanical prope...

Selective Laser Sintering (SLS) and Selective Laser Melting (SLM) are parent layer manufacturing processes that allow generating complex 3D parts by consolidating layers of powder material on top of each other. Consolidation is obtained by processing the selected areas using the thermal energy supplied by a focused laser beam. In SLS partial fusion of powder particles takes place, followed by a...

Lignin is introduced as a suitable component for selective laser sintering (SLS) of polyamide (PA12) to reduce costs while maintaining or improving processability and performance. Alkali lignin (sourced polydisperse, amorphous powder) was used at volume concentration up 60 vol % three-dimensional (3D) printing complex, layered structures. The latter were obtained high axial aspect objects, prod...

Abstract Polymers are widely used materials in aerospace, automotive, construction, medical devices and pharmaceuticals. being promoted rapidly due to their ease of manufacturing improved material properties. Research on polymer processing technology should be paid more attention the increasing demand for applications. Selective laser sintering (SLS) uses a sinter powdered (typical polyamide), ...
