Painting Resin 3D Prints: A Beginner’s Guide

Posted by

Are you looking to take your resin 3D prints to the next level? Painting is a great way to add a professional touch to your 3D printed objects. However, painting resin prints can be tricky and requires some preparation.

Before you start painting, it’s important to properly clean and prepare your resin print. Any leftover resin or debris can cause issues with the paint adhering properly. Sanding the print can also help create a smoother surface for painting. Additionally, using a primer can help the paint adhere better and create a more even finish. With the right preparation and techniques, you can create stunning painted resin 3D prints.

Preparing Your Resin 3D Print

Before painting your resin 3D print, it’s essential to prepare it properly to ensure that the paint adheres well and looks good. Here are the steps you should follow:

Cleaning Your Resin 3D Print

Cleaning your resin 3D print is the first step in preparing it for painting. Resin prints can be sticky or oily, so you must remove any residue or debris that may be on the surface. Here’s how to do it:

  1. Fill a container with warm water and add a small amount of dish soap.
  2. Place your resin 3D print in the container and let it soak for 10-15 minutes.
  3. Gently scrub the print with a soft-bristled brush to remove any remaining residue.
  4. Rinse the print thoroughly with clean water and let it dry completely.

Sanding Your Resin 3D Print

Sanding your resin 3D print is the next step in preparing it for painting. Sanding helps to smooth out any rough edges or imperfections on the surface of the print. Here’s how to do it:

  1. Use a coarse-grit sandpaper (around 80 grit) to sand the surface of the print.
  2. Move on to a finer-grit sandpaper (around 220 grit) to smooth out the surface further.
  3. Finish off with a very fine-grit sandpaper (around 400 grit) for a smooth finish.
  4. Clean the print with a soft tack cloth to remove any sanding dust.

By following these steps, you’ll have a clean and smooth surface that’s ready for priming and painting.

Priming Your Resin 3D Print

When it comes to painting your resin 3D prints, priming is an essential step that can make a significant difference in the final result. Priming helps create a smooth surface for paint to adhere to and improves the overall finish of your print. In this section, we will discuss how to choose the right primer for your resin 3D print and how to apply it correctly.

Choosing the Right Primer

Choosing the right primer is crucial for achieving a high-quality finish. There are several types of primers available, including spray-on primers, brush-on primers, and airbrush primers. When selecting a primer, consider the type of paint you plan to use, the color you want to achieve, and the surface texture of your print.

Spray-on primers are a popular choice for resin 3D prints because they provide an even and smooth coating. They are also easy to apply and dry quickly. However, they can be expensive and require proper ventilation when used indoors.

Brush-on primers are a more affordable option and can be applied with a brush or foam roller. They are ideal for small prints and can be used to achieve a variety of finishes, from matte to glossy.

Airbrush primers offer the most control over the application and can be used to achieve a very fine finish. They are best suited for experienced painters and require an airbrush and compressor to apply.

Applying Primer to Your Resin 3D Print

Before applying primer, make sure your print is clean and free of any dust or debris. Use a lint-free cloth or compressed air to remove any particles that may be on the surface.

When applying primer, it’s best to use thin, even coats. Start with a light coat and let it dry before applying additional coats. This will help prevent the primer from pooling or running, which can create an uneven finish.

When using spray-on primer, hold the can about 6-8 inches away from the print and use a sweeping motion to apply the primer. For brush-on primer, use a foam roller or brush and apply in thin, even strokes. Airbrush primer should be applied in several thin coats, allowing each coat to dry before applying the next.

Once the primer has dried, you can sand the surface lightly to remove any imperfections or rough spots. This will help create a smooth surface for painting.

In conclusion, priming your resin 3D print is an essential step in achieving a high-quality finish. By choosing the right primer and applying it correctly, you can create a smooth surface for paint to adhere to and improve the overall finish of your print.

Painting Your Resin 3D Print

When it comes to painting your resin 3D print, there are a few things to keep in mind to ensure that your finished product looks great. In this section, we’ll discuss how to choose the right paint for your project and how to apply it to your resin 3D print.

Choosing the Right Paint

Choosing the right paint is crucial to achieving the desired finish on your resin 3D print. Here are a few things to consider when selecting your paint:

  • Type of Paint: Acrylic paints are a popular choice for painting resin 3D prints. They dry quickly, are water-soluble, and come in a wide range of colors. Enamel paints are also an option, but they require longer drying times and can be more challenging to work with.
  • Primer: Using a primer can help the paint adhere better to the resin surface and provide a smoother finish. Look for a primer that is compatible with your chosen paint type.
  • Color: Consider the color of your resin 3D print when selecting your paint. If you’re painting a dark-colored print, you may need to use a lighter color as a base coat to achieve the desired color.

Applying Paint to Your Resin 3D Print

Once you’ve selected your paint, it’s time to start painting your resin 3D print. Here are some tips to keep in mind:

  • Prepare the Surface: Make sure the surface of your resin 3D print is clean and free of debris. Sanding the surface can help the paint adhere better.
  • Thin Coats: Apply thin coats of paint to avoid drips and runs. Allow each coat to dry completely before applying the next.
  • Multiple Layers: Depending on the desired finish, you may need to apply multiple layers of paint. Allow each layer to dry completely before applying the next.
  • Finishing: Once the paint has dried, you may want to apply a clear coat or varnish to protect the surface and provide a glossy finish.

By following these tips, you’ll be able to achieve a professional-looking finish on your resin 3D print.

Finishing Your Resin 3D Print

After printing your 3D model, the next step is to finish it off to give it a polished and professional look. Here are some tips on how to finish your resin 3D print.

Sealing Your Resin 3D Print

Sealing your resin 3D print is an important step in finishing it. This will protect your print from scratches and other damages, and also give it a glossy look. Here are some steps to follow when sealing your resin 3D print:

  1. Sand the surface of your print with a fine-grit sandpaper to remove any rough edges or bumps.
  2. Clean the print with a damp cloth to remove any dust or debris.
  3. Apply a thin layer of clear coat spray paint to the surface of your print. This will give it a glossy finish and protect it from scratches and other damages.

Adding Additional Details

After sealing your resin 3D print, you can add additional details to make it more interesting and unique. Here are some ways to add details to your print:

  1. Paint your print with acrylic paints. This will give it a pop of color and make it stand out.
  2. Use a paintbrush to add small details, such as eyes, buttons, or other small features.
  3. Use decals or stickers to add designs or logos to your print.

Remember, when adding additional details, it’s important to keep it simple and not overdo it. Too many details can make your print look cluttered and messy.

In conclusion, finishing your resin 3D print is an important step in making it look professional and polished. By following these simple tips, you can create a print that is both unique and visually appealing.
