| dc.description.abstract | Polyetheretherketone (PEEK) is one of the highest performance plastics in terms of heat and chemical resistance and mechanical strength. Laser sintering of PEEK requires high powder bed temperature above 300℃, and this pushes up machine price and pulls down powder recycle rate which leads to high material cost. The authors are proposing a modified laser sintering process which allows the bed temperature to be set lower than recrystallization temperature, namely low temperature process. In this research, bed temperature of 170 ℃, which is typical for PA12 process, and bed temperature of 200 ℃ which is same as previous study were tested. As a result, parts with a high relative density of more than 95% were obtained at both powder bed temperatures, and parts with a tensile strength of 80 MPa were obtained at a powder bed temperature of 170 °C. This shows that laser sintering of PEEK can be processed with a commercially available laser sintering machine resulting in drastic cost cut in terms of machine and material costs. | en_US |
