Utilize SLS to print nylon powder:
Step 1. The powder bin and build chamber are pre-heated to a temperature that a little bit below the melting point of the printing materials. This step will make it easier for the laser to raise the temperature of selective regions as it will shapes and traces those regions until the solid object is built.
Step 2. The recoating blade will disperse a thin layer of powder on the top of the build platform.
Step 3. The laser scans the contour of next layer, heating and sintering the materials selectively to a temperature that just below or right at the melting point of the materials, which fuses the materials in old layer and new layer together mechanically.
Step 4. The un-sintered powder supports the parts during the printing process, which means SLS doesn’t need dedicated support structures to create complex parts.
Step 5. When a layer is scanned, the build platform lowers to a pre-set thickness and the recoating blade spreads a new layer of powder. The process keeps repeating until the solid part is built.
Step 6. Cooling. After printing, the build chamber needs to cool down before the printed parts can be unpacked. This makes sure that mechanical properties of parts are optimized and avoid warping. But it takes times, sometimes may up to 12 hours.
Step 7. Post-processing. Then the parts are ready to unpack from the build chamber. The next step is to clean the excess powder on the parts, while the powders can be recycled and reused in the next printing. The parts afterwards can be further post-processed by blasting, grinding, and painting, etc.
1. How much does printing polypropylene (PP) cost?
2. What are the post-processing options for the polypropylene (PP) 3D printed parts?
3. How large of a part can I print with polypropylene (PP) materials?
4. Can I printing moving parts with polypropylene (PP) 3D Printing?
5. How to compare polypropylene (PP) and nylon?
Both nylon and polypropylene are durable and resistant to stress, but polypropylene is stronger than nylon. Besides, if parts will be used underwater, polypropylene printed part is waterproof.
