200°C ultra-high temperature engineering plastics complete 3D printing three-dimensional shape

It is reported that Prof. Shinno Jun of the Institute of Production Technology of the University of Tokyo has successfully completed the three-dimensional modeling of super engineering plastics with heat resistance of 150 ° C or higher using 3D printers . Compared with the existing processing methods such as cutting and injection molding, the strength of about 80% is achieved, and the complicated shape can be processed, which is advantageous for the production of high-temperature resistance required for the engine peripheral parts of automobiles and airplanes.

200°C ultra-high temperature engineering plastics complete 3D printing three-dimensional shape

Polyphenylene sulfide (PPS) having a melting point of 280 ° C, heat resistance of 150 ° C, and polyether ether ketone (PEEK) having a melting point of 360 ° C and a heat resistance of 200 ° C successfully completed the three-dimensional shape. The molding method is a powder lamination method in which a resin powder is irradiated with a laser, repeatedly dissolved, cooled and solidified, and a body shape is established. The furnace was kept at 200 ° C, and the resin powder was dissolved by raising the laser to about 400 ° C.

By increasing the laser area and evenly distributing the energy distribution, the powder can efficiently absorb heat to dissolve the resin. After the specification test piece for the strength test was formed, it was confirmed that the strength reached about 80% of the other processing methods. In the future, intensity data of different basic shapes will be collected, and a design system capable of predicting the strength in shape design will be developed.
