Characterization of SLS parts for drug delivery devices

There are many applications for rapid prototyping systems and application i n the biomedical field is an important domain. Uses selective laser sinteri ng (SLS) in this study to build porous cylindrical disc matrices for use as drug delivery devices (DDD). Studies the part-bed temperature to ascertain its influence over the porosity of the disc matrices. They are found to ha ve an inverse linear relationship. Also investigates the dense walls, the i nherent consequences of building porous structures with the SLS, in the dis c matrix as they have a direct impact on the performance of the DDD. Discus ses the size constraint of the disc matrix due to the limitations of the SL S process. Also investigates the possibility of creating disc matrices of v arying porosity. Experimental results demonstrate that SLS is viable in pro ducing DDDs that have variable porosity and micro-features.
