3D printing has revolutionized manufacturing, prototyping, and even art. Among the various methods of 3D printing, Stereolithography (SLA) and Fused Deposition Modeling (FDM) are two of the most popular. While these technologies are powerful, the prints they produce often require post-processing to achieve the desired finish and durability. However, the post-processing requirements for SLA and FDM prints differ significantly due to the nature of the materials and processes involved.
Before diving into post-processing, it’s essential to understand how these two printing technologies work.
FDM prints often require support structures to hold overhanging parts during printing. Once the print is complete, these supports need to be removed, which can leave rough surfaces or marks on the print.
After support removal, any gaps or imperfections need to be filled. Common materials used for this include epoxy resin, autobody filler, or an ABS and acetone compound. This step is crucial for creating a smooth, finished appearance, especially if the print has been divided into parts that need to be assembled.
Sanding is a common post-processing technique used to smooth out the surface of FDM prints. While it can create a polished finish, sanding is not recommended for prints with only one or two perimeter shells or those with small, intricate details. Aggressive sanding can remove too much material, affecting the accuracy of the part.
After sanding and smoothing, FDM prints are often primed and painted to enhance their appearance. This step not only conceals any remaining imperfections but also provides UV protection, preventing the print from yellowing or degrading over time.
Like FDM, SLA prints often require support structures that need to be carefully removed. The parts are also typically washed in isopropyl alcohol to remove any uncured resin from the surface. This initial cleaning step is crucial to achieving a smooth final finish.
SLA prints can be sanded and polished to remove layer lines and achieve a glass-like surface.
Applying mineral oil to an SLA print can further smooth the surface and reduce friction. This method is similar to wet sanding but leaves an oily layer that can conceal discoloration and improve the print’s feel. However, it makes the surface challenging to paint, as the oil prevents proper adhesion.
Painting is a common next step for SLA prints, especially when a smooth, uniform finish is required. Spray-painting helps to conceal any remaining layer lines and protects the print from UV exposure, which can cause discoloration or post-curing effects over time.
Understanding the post-processing requirements of SLA and FDM is crucial for achieving the best results with each technology. While FDM may require more intensive post-processing to achieve a high-quality finish, its versatility and accessibility make it a popular choice for many applications. SLA, on the other hand, offers finer details and smoother surfaces, with post-processing steps that focus more on preserving the integrity and appearance of the print. By mastering these post-processing techniques, you can significantly enhance the quality and durability of your 3D prints, regardless of the printing method used.
