Step-by-step Guide to Painting 3D Printed Objects

Here are the essential steps to successfully paint 3D printed objects.

  1. Cleaning and Preparing the Surface

    Wash your 3D printed object with warm, soapy water, using a soft brush for stubborn spots. This removes grease and dust that can affect paint adhesion.

    For the final wipe-down, use isopropyl alcohol (At Least 70%). Ensure the surface is dry before moving on—moisture can interfere with paint.

  2. Selecting the Right Primer

    Choose a primer designed for plastics to avoid peeling paint. You can spray or brush it on, but spraying provides a more uniform finish; aim for a lightweight coat.

    Apply it at around 15-30°C (59-86°F). Hold your spray can about 20-30 cm (8-12 Inches) from the surface to prevent drips.

  3. Choosing the Right Paint

    Select paint based on your object’s material; acrylic paints work well on PLA, while enamel paints are better for ABS. Always use paint suitable for plastic as it adheres better and lasts longer. If you’re curious about mixing colors to achieve the perfect brown shade, painting plastic materials.

    Paint thickness can vary, with thinner layers typically offering greater durability. If unsure, test different paints on scrap pieces before deciding.

  4. Applying Paint Techniques

    Start with thin coats using a spray can or airbrush for an even finish; wait at least 15-30 minutes between layers. Keep a small distance between the spray and the object to avoid pooling or dripping. If you’re working with a surface previously coated in polyurethane, you’ll want to ensure proper adhesion by preparing the surface for chalk paint.

    Consider techniques like washing or dry brushing for effects later. Don’t forget to layer your painting—depth is important for the final look!

  5. Sealing and Protecting Your Artwork

    Once the paint is dry, apply a clear coat for protection against scratches and UV damage; it also gives a professional finish.

    Use a spray sealant, applying it lightly for even coverage. Allow it to dry thoroughly and keep it away from humidity—moisture can easily ruin your finish!
