As versatile as 3D printers are when they turn digital 3D models into real-world objects, rarely do 3D printed projects come out with professional-grade quality without some degree of post-processing. With the proper finishing technique, you can give your plain plastic 3D prints a more polished, mirror-like appearance.

 .

The appropriate finishing technique will depend on the results you’re looking for and the type of plastic material you’re working with. In this article, we’re focusing on one of the most common in the 3D printing world – PLA.

 .

Why bother finishing your PLA prints anyway? The approach of FDM printers towards additive manufacturing involves laying down thin layers of molten filament on top of one another, gradually building an object based on a reference 3D model. While this technique gives the technology an incredible amount of design flexibility, it also has its inherent flaws. One glaringly obvious characteristic of a […]
