After the SLS 3D printer is initiated, it uses a laser to sinter the material layer by layer onto a heated bed of nylon-based powder according to the geometry of the component. Once a layer of powder has been fused, a roller or a recoater blade moves smoothly across the powder bed to evenly spread the next layer of powder. This process repeats layer by layer until the entire component is printed. After the printing job is completed, the entire powder bed containing the encapsulated components is transferred to the breakout station. At the breakout station, the powder bed is slowly lifted, and then the components are separated and removed from the powder. Next, the staff will carry out an initial manual cleaning to brush off most of the loose powder. Subsequently, the components undergo sandblasting to thoroughly remove any remaining powder residue. After these steps, the components are sent to the post-processing department for subsequent fine finishing. |
