About Project

The fist model is built from a 3D scanned human hand, and 3D printed with Nylon PA 12. After the default sanding process, there are still slight but visible layer lines. The veins and wrinkles are obvious, while the pattern on the ring is rough.

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 PA 12 powders. On a bed pressure, a 0.1 mm thick layer over the whole width is applied.
• Step 3: Pre-heat the machine to about 100°C, and the laser will lit 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.
