About Project

Polypropylene (PP) material could be 3D printed with Selective Laser Sintering(SLS) Technology and it features fatigue resistance, semi-flexible, and lightweight characteristics. Here are some sample PP parts. They are not pure white, but yellowish-grey.

Solution

• Step 1: First, the 3D model will be broken down into layers of 0.1 mm on the computer and sent to the 3D printer.
• Step 2: Before printing, we need to fill the tank with SLS Polypropylene (PP) powders. On a bed pressure, a 0.1 mm thick layer over the whole width is applied.
• Step 3: Pre-heat the machine to above 100掳C, and the laser will light the powder and increases the temperature just above the melting point of the powders.
• Step 4: After a layer is formed, the platform will lower down and produce another layer.
• Step 5: When the printing process ends, remove the excess powders which also serve as supports.
