3D Printed Object: Your 3D printed object with raised letters. Ensure it's clean and dry.
Primer: A high-quality, water-based primer like Rust-Oleum Universal Paint + Primer or Zinsser Bulls Eye 1-2-3 Primer.
Acrylic Paint: Acrylic paint in the color(s) of your choice. Some popular options include FolkArt, DecoArt Americana, and Plaid.
Paint Brushes: Fine-tip, detail paintbrushes for the letters, and a larger brush for the primer and base coat. A size 0/00 or 000 brush is great for intricate details.
Painter's Tape: To protect areas you don't want to paint.
Razor Blade or Sandpaper: For lightly smoothing the raised letters.
Palette: To mix and test your paint colors.

Prepare Your 3D Print

Before you start painting, it's essential to prepare your 3D print for a smooth application:

Clean your print to remove any residual dust, oils, or supports using isopropyl alcohol and a soft brush.
Allow your print to dry completely.
Use a razor blade or fine-grit sandpaper (1200-2000 grit) to lightly smooth the raised letters. Be careful not to sand through the surface.
Wipe off any debris with a damp cloth and let it dry.

Apply Primer

Primer is essential for creating an even surface, increasing paint adhesion, and preventing the paint from soaking into the plastic.

Paint a thin, even coat of primer onto your 3D print using a larger paintbrush. Don't forget to prime the backside of the letters for an all-over finish.
Allow the primer to dry completely, according to the manufacturer's instructions. Most primers take around 30 minutes to 1 hour to dry.
Lightly sand the primed surface with a fine-grit sandpaper to eliminate any imperfections. Wipe off any dust with a damp cloth.

Now that your 3D print is primed and ready, it's time to paint those raised letters!

Choose the acrylic paint color(s) you'd like to use. For opaque colors, you can use them directly. For translucent colors, you may need to apply multiple coats or use a base color.

Base Coat

Start by applying a base coat of acrylic paint in your chosen color using a fine-tip paintbrush. This step helps ensure even coverage and can make touch-ups easier:

Dip your brush into the paint and gently blot the excess onto a paper towel.
Start at one corner of the letter and work your way across, trying to maintain a consistent thickness.
Allow the base coat to dry for the recommended time (usually around 15-30 minutes).

Touch-ups and Final Coat

Once the base coat is dry, it's time to apply the final layer of paint and make any necessary touch-ups:

Examine the letters for any missed spots or areas that need to be touched up. Using a fine-tip brush, paint these areas carefully.
Allow the touch-ups to dry for a few minutes. If satisfied with the results, skip to step 4. If not, apply another thin layer of paint to the entire letter to even out the color.
Lightly sand the painted surface using a very fine-grit sandpaper (2000-2500 grit) to smooth any raised edges or imperfections. Wipe off any dust with a damp cloth.
Apply a second, final coat of paint to the raised letters, following the same process as the base coat. Allow it to dry completely.

Congratulations! You've successfully painted raised letters on your 3D print. Display your unique creation proudly, or gift it to someone special. As you continue to experiment with painting on 3D prints, consider trying different color combinations, techniques, or even adding other embellishments like glitter or custom textures. Happy painting!
