How To Clean 3D Resin Prints

3D printing has revolutionized various industries, including manufacturing, healthcare, and even hobbies. Resin-based 3D printing, in particular, has gained popularity due to its ability to create intricate and detailed models.

However, once you’ve completed a 3D resin print, it’s essential to properly clean and finish the object to achieve the desired result. That lead us to revealing how to clean 3D resin prints.

To clean 3D resin prints effectively, use 90%-99% concentration isopropyl alcohol (IPA) for rinsing, ensuring to soak the print for 5-10 minutes in each stage. Patience is key; so, allow the IPA to dissolve the uncured resin completely.

In this article, we will explore effective methods and techniques for cleaning 3D resin prints. This guide will help ensure a pristine and professional finish.

Understanding Resin Prints

Before diving into the cleaning process, it’s crucial to have a basic understanding of resin prints. Resin-based 3D printers use liquid photopolymer resin that hardens when exposed to ultraviolet (UV) light.

The process involves layer-by-layer curing, resulting in the creation of highly detailed models. However, after printing, the object requires post-processing to remove excess resin and support structures.

How To Clean 3D Resin Prints: A Complete Guide

Cleaning 3D resin prints requires some preparation to ensure a successful outcome. Here are the key steps to follow before you begin the cleaning process:

  1. Safety First: Before handling any cleaning materials or chemicals, make sure to wear protective gloves and safety glasses to protect your skin and eyes.
  2. Gather Essential Supplies: Collect the necessary supplies for cleaning, such as isopropyl alcohol (IPA), a soft-bristle brush, a plastic container, and a clean, lint-free cloth.
  3. Remove Excess Resin: Carefully remove the 3D resin print from the printer’s build plate, ensuring not to damage the object. Gently scrape off any excess resin or support structures using a scraper or craft knife.
  4. Support Removal: If your print has support structures, carefully remove them using pliers or tweezers. Take your time to prevent damaging the print while removing the supports.

Cleaning Process

Now that you’re prepared, it’s time to delve into the cleaning process. Below, we’ll outline a step-by-step guide to clean your 3D resin prints effectively:

Step 1: Initial Rinse

To start, you’ll need to perform an initial rinse to remove the majority of uncured resin from the print. Follow these steps:

  1. Fill a plastic container with isopropyl alcohol (IPA) to an adequate level.
  2. Place the 3D resin print into the container, ensuring it is fully submerged.
  3. Gently agitate the container or lightly brush the print to help dislodge any remaining resin.
  4. Leave the print in the IPA for approximately 5-10 minutes to allow the alcohol to dissolve the uncured resin.

Step 2: Secondary Rinse

After the initial rinse, a secondary rinse is necessary to remove any remaining resin residue. Here’s how to proceed:

  1. Prepare a new container of IPA for the secondary rinse.
  2. Transfer the 3D resin print to the fresh container, discarding the IPA from the initial rinse.
  3. Repeat the gentle agitation or brushing to ensure thorough cleaning.
  4. Allow the print to soak for another 5-10 minutes, allowing the IPA to dissolve any lingering resin.

Step 3: Final Rinse and Drying

The final rinse ensures all residual resin and cleaning solution are removed from the print. Follow these steps for the last stage of the cleaning process:

  1. Prepare a container with fresh, clean IPA.
  2. Transfer the print to the container for a final rinse.
  3. Swirl the print gently in the IPA to ensure all surfaces are adequately cleaned.
  4. Remove the print from the IPA and pat it dry with a clean, lint-free cloth.
  5. Allow the print to air dry fully before proceeding with any additional post-processing steps.

Tips for Effective Cleaning

To clean 3D resin prints efficiently and achieve the best results, consider the following tips:

  • Use the right IPA concentration: The optimal IPA concentration for cleaning resin prints is typically between 90% and 99%. Lower concentrations may not be as effective in removing the resin residue.
  • Be patient: Ensure you give enough time for the print to soak in the IPA during each rinse stage. This allows the alcohol to dissolve the uncured resin effectively.
  • Use appropriate safety precautions: When working with IPA or other cleaning chemicals, always follow safety guidelines and work in a well-ventilated area.
  • Inspect your print: After cleaning, inspect the print for any remaining resin or imperfections. If necessary, you can use a soft-bristle brush or toothbrush to remove stubborn residue.

Final Tip

Cleaning 3D resin prints is a crucial step in achieving a professional and polished final product. By following the proper cleaning techniques outlined in this article on how to clean 3D resin prints, you can ensure your prints are free from excess resin and support structures.

Remember to prioritize safety throughout the process and take your time to achieve the best results. With a little patience and care, your 3D resin prints will showcase the intricate details and quality you envisioned.

Additionally, keep in mind the tips provided, such as using the appropriate IPA concentration and being patient during the cleaning process. By adhering to these guidelines, you’ll be able to achieve outstanding results with your 3D resin prints.
