Enhancing Surface Finish with Post-Processing Techniques

Stereoscopy is a critical process in 3D Printing. Which greatly contributes to the final aesthetic appeal of the printed part as opposed to post-processing. Where the aesthetic surface finish is boosted during 3D Printing. The adopted method of printing allows the creation of highly detailed and functional models. However, after the printing process is complete additional steps can be taken to refine the visual appearance of the object. This article provides insight into the different techniques of post-processing for your final 3D-printed parts.

Sanding and Polishing

One of the techniques is sanding, which can be named one of the most widespread. And, at the same time, efficient kinds of post-processing. The second is where abrasive paper with different abrasive particle sizes, is commonly referred to as sandpaper. It is applied by rubbing the surface of the print to smoothen it. The right approach is to use a coarser sandpaper number, the first one (i.e., 100-200) to remove larger imperfections on the material’s surface. And then gradually work your way up through successively finer sandpaper numbers (400-2000). 

When it is necessary to get the optimum outcome use the wet sanding because it reduces dust. And provides a refined smoothness. Polishing or waxing can add up the finishing after sanding and can be done to improve its appearance. After the application of the wax finish, it should be polished by using a good-quality polishing compound and a soft cloth until it glistens. It is most useful on plastics like PLA as well as ABS due to the characteristics of the materials and the process.

Chemical Smoothing

Chemical smoothing entails taking the print and using some chemicals that dissolve off the outer layer. Thus enhancing the surface smoothness. One such finishing method is known as acetone vapor smoothing, which applies to ABS prints. Carefully position the print in an enclosed container that contains a bit of acetone, the fumes will help to flux the skin’s surface of the print. It is crucial to note that this process may require proper ventilation of the room. Or require protective measures to be applied. For PLA, a resolution, such as a tetrahydrofuran (THF) can be possible. But these are rare because of the high dangers involved. It is also important to remember the inherent danger that is associated with most chemicals. Thus always research them and always handle them with a lot of precaution.

Painting and Coating

Another useful technique that can be applied to eject 3D printed Products with enhanced surface finish is painting. One of the best ways to begin is by applying the primer, to make sure you have a correctly smooth surface to work with. Once the printer is done, it is recommended to use spray paint or acrylic paints. It is done to add color and detailing to the work.  It may require the application of separate layers and this can take some time. The last layer should be a clear one, which will give your paint a polish and help it stay smooth and shiny.

For decorative parts, colors such as black can be applied to enhance the beauty of a particular material. While for functional parts, coats like epoxy resin can be added to enhance strength and give it a better surface finish. Another advantage is that epoxy itself can get into small pores. After drying, produce a homogeneous, rather dense film.

Using a 3D Printer Silicone Sock

One prescribes the quality of the print, therefore, keeping the temperature for printing constant is important. It helps in obtaining a print with a polished surface. So here comes a question what should be used for this purpose? The 3D Printer Silicone Sock is an encapsulating structure used on the hot end part of a 3D printer. It is used to ensure it is insulated and holds heat appropriately. This means that there will be a consistent supply of filament that leads to the reduction of defects. And the enhancement of the first layer quality in the print. Which eliminates the use of a lot of refining on the printed objects.

Conclusion

We take a look at different post-processing techniques. You can use these to improve the surface finish and appearance of your 3D-printed parts from decent to near perfect. Some of these techniques include sanding, chemical smoothing, and painting. Even the use of accessories like the Silicone Sock can help enhance the overall appearance and quality of any of your prints. When you use such methods, and apply them properly as described here, your 3D printed works will turn out perfect. Like those done by professionals.
