We sand down the 3D-printed parts to remove the visible layer lines, support residue, and any other imperfections. This process takes longer depending on how detailed your parts are.

Wear eye protection!!! You do not want plastic particles or spray paint in your eyes.

Recursive Sanding Steps

1. Sand/File down surfaces

   • Circular motions

   • Light pressure

2. Put 1 part on a painting stick bundle (has a thick end for slotting parts onto)

3. Spray light coat of filler primer

   • Avoid drippage

4. Transfer part onto singular wooden rod and set in drying station

5. Let part dry for ~30 minutes

   • Keep your parts on the same rod for drying

6. Repeat as needed using higher sand paper grits

   • Typically 3-4 times

   • 120-400 grit

Quick Spray Painting Tips:

• Hold spray paint can 8-12 inches away from the parts

• Use sweeping motions

• Apply multiple thin coats instead of one thick coat

• Do not touch wet paint

Recursive Painting Steps

1. Apply 1 coat of black paint.

   • Black paint as a background makes the other colors stand out

2. Use painter's tape to cover areas you do not want painted. Apply 1-2 coats of desired color.

3. Transfer part onto singular wooden rod and set in drying station

4. Let part dry for ~30 minutes

   • Keep your parts on the same rod for drying

5. Repeat as needed for all colors/areas.

Detail Painting

Use brushes with acrylic paint for any high-detail spots.

• Layer many thin coats

After you are satisfied with the paint job, apply a final layer of clear coat. This protects your parts from the environment and enhances their final appearance.

It is very difficult to do anymore painting after clear coat is applied.
