Fabrication of scaffold in tissue engineering using selective laser sintering process

Bone defects are serious complications that are caused by extensive trauma or tumor. The traditional therapies fail to repair these defects. Tissue engineering scaffold can be used to regenerate the damaged tissue. This paper describes an experimental investigation of bone scaffold to measure the porosity using gas porosimeter and suggest an alternative to bone scaffold. The prototype was made using additive manufacturing of selective laser sintering technique. The material chosen for the study was synthetic polymer PA12. The behaviour of actual bone and prototype had been observed under compressive load of fixed interval loading condition. Mechanical properties of polymer had been evolved and compared with actual bone
