Mastering Post-Processing: 5 Steps to Post Process Resin Prints

How to perform resin 3D printing post-processing is crucial to enhance the final appearance of the print, as well as stabilizing its performance. Being able to professionally handle complex models is an essential skill for mastering 3D printing, which will help us achieve smoother surfaces, clearer details, maintain and improve the performance of resin prints. Many 3D printing beginners are curious or are learning this technique, keep reading and we will provide five basic steps for post-processing resin prints. Taking models off the build platform and trying them out, it will be a way to enhance your 3D printing experience.

Post-Processing Guide: 5 Steps to Post Process Resin Prints

The post-processing of resin prints involves the application of several techniques. The most basic five steps are: cleaning, drying, curing, removing supports, and smoothing the surface. Below is a step-by-step guide to post-processing your resin prints.

Step 1: Clean the print with isopropyl alcohol to remove liquid resin from the surface

After completing the 3D print, we remove the resin print from the build platform and first need to clean it with a cleaning solution. Liquid resin remains on the surface of the print, and uncured resin should not come into direct contact with the skin. Using a common cleaning solvent for resin prints, such as isopropyl alcohol, can effectively remove excess resin. Ensuring that there is no sticky residue on the surface of the print is the first step in post-processing resin prints.

Step 2: Drying the Resin Print

Drying the resin prints after cleaning will further ensure the quality and durability of the 3D printed model. Use tools to blow dry or air dry the resin prints, preferably to complete the cleaning and drying of excess liquid in the crevices, to avoid residual liquid interfering with the subsequent curing of the resin prints. During the drying process, do not use an open flame and it is best to avoid overheating.

Step 3: Curing the resin print under a UV light source

Curing is important for the post-processing of resin prints. Curing after printing can ensure that the resin on the surface of the model is completely polymerized and hardened, which can enhance the mechanical properties and maintain its expected shape and size. Curing resin prints requires the use of a UV light source to minimize residual resin tackiness. Use a professional curing machine, such as Anycubic Wash & Cure Plus Machine, to ensure uniform and thorough curing throughout the print.

Step 4: Removing Support from Resin Prints

In resin printing, it is often necessary to add supports to give the model the necessary stability. After the printing is complete, we can remove the supports and successfully print complex models. Needle-nose pliers and flat cutter are two of the most commonly used tools for most of these needs. Detailed instructions for use: Tool for removing resin print supports.

Step 5: Sand the Resin Prints to Smooth the Surface

After completing the above steps, the main work of post-processing resin prints has basically been realized. Sanding resin prints as the last step can be done optionally, the main purpose is to smooth the surface, eliminate the layer lines, and get a more delicate surface. Sandpaper is the most commonly used tool: How to use sandpaper to smooth resin prints.

Post-Processing Resin Prints: In Conclusion

The post-processing of resin printing needs to deal with chemicals such as resins and solvents. Please take protective measures and wear gloves, protective glasses and other equipment. Uncured resin and cleaning solvents usually have an odor, so it is best to work in a well-ventilated environment, or add air filtration measures. The steps for post-processing resin prints can help you obtain a clean and dry surface for your prints, as well as complete the basic processing of the printed product. If you are interested, you can continue to experiment with different techniques and materials to find the post processing method that works best for you.
