About Project

Although the material page of SLS Nylon PA 12 tells us that the material is not suitable for making fine-detail models with smooth surfaces and large models, the crocodile statue we made shows the limit of nylon printing technology. When the scale is large enough, the model would also contain rich details. As our maximum build volume is 700 x 380 x 580 mm, the crocodile can be perfectly printed in one piece.

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掳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.
