How to Paint Resin 3D Prints: A Step-by-Step Guide

If you have recently started 3D printing, you may be wondering how to paint your resin 3D prints. Painting your 3D prints can take your creations to the next level, adding a personal touch and making them stand out. However, painting resin 3D prints can be tricky, especially if you are new to the hobby. In this article, we will guide you through the process of painting resin 3D prints, from preparation to finishing touches.

Before painting your resin 3D prints, it is crucial to properly clean and prepare them. Resin prints require a bit more preparation than other types of 3D prints due to their sensitive nature. You will need to remove any excess resin, sand the surface, and prime the prints before painting. Skipping these steps can result in a poor paint job and a less-than-perfect finished product.

In the next section, we will discuss the necessary steps for preparing your resin 3D prints for painting.

Preparing the Print

Before you start painting your resin 3D print, it is important to prepare it properly. This section will cover the three main steps to prepare your print: cleaning, sanding, and applying primer.

Cleaning

The first step in preparing your print is to clean it thoroughly. Resin prints can have leftover resin on them, which can ruin the fine details in your figures or miniatures. To clean your print, you will need to immerse it in isopropyl alcohol (IPA). It is recommended to repeat this process twice to ensure that any remaining resin is removed.

Sanding

After cleaning your print, the next step is to sand it. This will help to smooth out any rough edges or imperfections in the print. You can use sandpaper or a sanding sponge for this step. Start with a coarse grit sandpaper and work your way up to a finer grit. Be sure to sand evenly and avoid sanding too much in one area.

Applying Primer

The final step in preparing your print is to apply primer. This will help the paint adhere better to the print and provide a smoother surface for painting. You can use a spray primer or brush-on primer for this step. Apply a thin, even coat of primer and allow it to dry completely before painting.

By following these steps, you can ensure that your resin 3D print is properly prepared for painting.

Painting Techniques

When it comes to painting your resin 3D prints, there are several techniques you can use to achieve a professional-looking finish. In this section, we will discuss three popular painting techniques: brush painting, airbrushing, and detailing.

Brush Painting

Brush painting is a popular and straightforward technique that involves using a brush to apply paint to your 3D print. To get the best results, it’s essential to use the right brush. A brush with soft bristles will help you achieve a smooth finish, while a brush with stiff bristles is better suited for textured surfaces.

Before you start painting, make sure to clean your 3D print thoroughly and apply a primer. This will help the paint adhere better and prevent it from chipping or peeling. When applying the paint, use thin coats and wait for each coat to dry before applying the next one. This will help you achieve a smooth and even finish.

Airbrushing

Airbrushing is a more advanced painting technique that involves using an airbrush to apply paint to your 3D print. This technique allows you to achieve a more precise and controlled finish, making it ideal for detailed or intricate designs.

To airbrush your 3D print, you will need an airbrush gun, an air compressor, and paint. Before you start painting, make sure to clean your 3D print thoroughly and apply a primer. When airbrushing, use thin coats and build up the color gradually. This will help you achieve a smooth and even finish.

Detailing

Detailing is a technique that involves adding small details to your 3D print using a fine brush or a marker. This technique is ideal for adding small accents or highlights to your design.

To detail your 3D print, you will need a fine brush or a marker and paint. Before you start detailing, make sure to clean your 3D print thoroughly and apply a primer. When detailing, use a light touch and build up the color gradually. This will help you achieve a precise and detailed finish.

In conclusion, there are several techniques you can use to paint your resin 3D prints, each with its advantages and disadvantages. Brush painting is a popular and straightforward technique, while airbrushing allows you to achieve a more precise and controlled finish. Detailing is ideal for adding small accents or highlights to your design.

Finishing Touches

Now that you have painted your resin 3D print, it’s time to add some finishing touches to make it look even better. Here are some tips to help you achieve a professional finish.

Sealing

After painting your resin 3D print, it’s a good idea to seal it to protect the paint and give it a smooth, glossy finish. There are several options for sealing your print, including clear coat spray, epoxy resin, or a brush-on sealer.

Clear coat spray is a quick and easy option that provides a glossy finish. Simply spray a thin coat over your painted print and let it dry. Repeat this process until you have achieved the desired finish.

Epoxy resin is a more durable option that provides a thick, glass-like finish. Mix the resin according to the manufacturer’s instructions and apply it to your print with a brush. Let it dry for several hours before handling.

Brush-on sealers are another option that provides a more matte finish. Apply the sealer with a brush, making sure to cover the entire surface of your print. Let it dry completely before handling.

Displaying

Once your resin 3D print is finished, you’ll want to display it in a way that shows off its beauty. Here are some ideas for displaying your print:

  • Use a display case: A display case is a great way to protect your print while showing it off. You can find display cases in a variety of sizes and styles to fit your needs.
  • Mount it on a stand: Mounting your print on a stand is a simple and elegant way to display it. You can find stands in a variety of materials, including wood, metal, and acrylic.
  • Hang it on the wall: If you don’t have a lot of space for displaying your print, consider hanging it on the wall. You can use picture hangers or adhesive strips to hang your print securely.

By following these tips, you can take your resin 3D print to the next level and create a beautiful, professional-looking finished product.
