The most critical step in the post-processing of fdm3d printing technology is

Sandpaper grinding: Sandpaper is the most common grinding tool. It should be noted that water should be added before grinding to avoid overheating and fluffy materials.

2. acetone polishing: acetone can also dissolve ABS materials, so? ASB model can also be polished with acetone, mainly by steaming 3D model with acetone. PLA materials cannot be polished with acetone.

3.PLA polishing solution: the operation steps are as follows: after the polishing solution is put into the operation vessel, the model is hoisted by iron wire or rope and soaked in the vessel with the polishing solution added. The soaking time should not be too long, only about 8 seconds. ?

4. Surface sandblasting. This is also a very common polishing method, which can also ensure the smoothness of surface treatment. The principle is that the compressed air is used as the power to make the high-speed jet beam spray on the surface of the model to be processed to achieve the polishing effect, and the sand blasting speed is faster than the polishing speed. No matter the size of the model, the surface can be smoothed by sandblasting. ?
