Here are some great techniques for professionally painting your 3D printed models.
What you'll need
- Wood block
- Nail buffing sticks
- Fiber backed polishing paper
- Tack cloth
- Masking tape
- Spray clearcoat
- Safety equipment: gloves and mask
1. Mount the primed part
Drill a starter hole in an inconspicuous spot and mount the primed part on a thin dowel. Insert the dowel into the wood block.
2. Polish the surface
Using the nail buffing sticks, gently polish the surface starting with level #2 (buff) and finishing with level #3 (polish) until the surface is glossy.
3. Remove dust
Run a tack cloth over the surface to remove dust.
4. Stir the paint
Gently swirl the can for 2 to 3 minutes.
Avoid shaking the can to prevent bubbly paint.
5. Spray on the undercoat
Always start and end your spray off of the model. Keep the nozzle 6” away and move quickly across the surface while rotating the model. Let the model dry for 20 to 30 minutes between layers. Apply a total of 2 to 3 layers.
Polish between layers with the finest sanding paper and a polishing stick for a glossy finish.
6. Mask areas you want to keep in the undercoat
Cut the masking tape with scissors or an X-Acto knife. Apply the tape firmly. Press down on the edges to keep paint from seeping underneath.
7. Apply the topcoat (optional)
A contrasting topcoat can create rich gradients. 1 or 2 light topcoats is enough.
8. Finish with the clearcoat
Apply 1 to 2 thin layers of clearcoat.
