Painting PLA prints offers a fantastic opportunity to add color and customization to your 3D printed objects. Whether you prefer airbrushing, spray painting, or brush painting, each technique provides a unique way to bring your PLA prints to life. In this article, we will guide you through an overview of the steps of painting PLA prints using airbrushing, spray painting, and brush painting techniques.
I. Preparing the PLA Print:
Before diving into the painting process, it’s crucial to prepare the PLA print properly. Follow these steps:
- Clean the Print: Thoroughly clean the PLA print using mild soap and water to remove any dust, oils, or debris. Allow it to dry completely before proceeding.
- Optional Sanding: If desired, lightly sand the surface of the print with fine-grit sandpaper to create a smoother texture and promote better paint adhesion. Be cautious not to apply excessive heat that may cause the PLA to melt.
II. Airbrushing Techniques:
Airbrushing allows for precise control and the creation of smooth gradients. Follow these steps for airbrushing painting PLA:
- Recommended Products:
– Airbrush Set: Paasche Airbrush TG-300R Double Action Gravity Feed Airbrush Set. This Made in USA airbrush is a solid choice for beginner or pro.
– Airbrush Paints: Look for Createx Airbrush Colors, an American brand offering a wide range of acrylic paints suitable for airbrushing PLA prints. U.S. Art Supply 24 Color Acrylic Paint set is a ready to spray versatile set.
- Thin the Paint:
– Follow the manufacturer’s instructions to properly thin the acrylic paint for airbrushing. Achieve a consistency that allows the paint to flow smoothly without being too watery.
- Test and Adjust:
– Perform a test spray on a scrap piece or inconspicuous area to ensure proper paint flow and adjust the airbrush settings if necessary.
- Airbrushing Techniques:
– Hold the airbrush approximately 6-8 inches away from the print.
– Apply thin, even coats of paint, gradually building up the desired color intensity.
– Maintain consistent strokes and keep the airbrush moving to avoid uneven coverage or pooling of paint.
– Allow each coat to dry before applying additional layers.
III. Spray Painting Techniques:
Spray painting provides quick and efficient coverage, making it suitable for larger areas and solid color applications. Follow these steps for spray painting PLA:
- Rust-Oleum 2X Ultra Cover spray paints offer good coverage for PLA prints.
- Shake and Test:
– Shake the spray can vigorously according to the manufacturer’s instructions.
– Perform a test spray on a scrap piece to ensure proper paint flow and color match.
- Applying the Paint:
– Hold the spray can approximately 6-8 inches away from the print.
– Apply thin, even coats using smooth and consistent motions.
– Allow each coat to dry before applying additional layers.
IV. Brush Painting Techniques:
Brush painting allows for detailed work and intricate effects. Follow these steps for brush painting PLA:
- Recommended Brushes:
– Royal & Langnickel brushes offer a variety of brushes suitable for acrylic paint.
- Painting Techniques:
– Dip the brush into the paint and remove any excess by gently tapping it on the edge of the container. A fun project is to 3D printing your own customized paint palette.
– Apply thin coats of paint using smooth and even brush strokes.
– For detailed areas, use smaller brushes, gradually transitioning to larger brushes for broader sections.
– Allow each coat to dry before applying additional layers or adding finer details.
Painting PLA prints allows you to unleash your creativity and enhance the visual appeal of your 3D printed objects. Whether you choose airbrushing, spray painting, brush painting or a combination, each technique offers its own advantages.
May your 3D journey be full of colorful works of art.
