The authors are developing a laser sintering process to fabricate highly porous
models with such high porosities as 90% and more. In the process, water-soluble filler is
mixed with designated plastic powder and leached out after laser sintering process is
finished to generate pores where the grains used to exist. Previously, the authors
reported successful application of this technology on a tissue engineering scaffold.
However, relationship between process parameters and obtained results has not been
clarified. This paper reports experimental investigation into effects of optimizing
process parameters such as mixture, grain size of the filler on resultant porosity, pore
size and process resolutionMechanical Engineerin
