Mistake #1: Sanding an object printed with cheap filament.
All 3D filament is not equal. Starting with a better quality filament will give you a better final product. Sanding will be smoother and more consistent with a quality filament.
Mistake #2: Not sanding in the direction of the layer lines.
When sanding your 3D print, it is important to sand in the direction of the layer lines. This will help to avoid creating scratches and gouges in the print.
Mistake #3: Using too much sanding pressure.
When sanding your 3D print, it is important to use light pressure. Using too much pressure can damage the print.
Mistake #4: Not using the correct grit sandpaper.
When sanding your 3D print, it is important to use the correct grit sandpaper. Start with a coarse grit sandpaper, such as 100 grit, and work your way up to a finer grit sandpaper, such as 400 grit.
Mistake #5: Not using water when sanding.
When sanding your 3D print, it is important to use water. This will help to prevent the sandpaper from clogging and will also help to produce a smoother finish.
Mistake #6: Not using a primer before painting.
If you plan to paint your 3D print, it is important to use a primer first. This will help the paint to adhere to the print and will also produce a more even finish.
Here are a few additional tips for smoothing your 3D print:
- Use a sanding block. A sanding block will help you to sand your print evenly.
- Take your time. Smoothing your 3D print can take some time. Don't rush it, or you may damage the print.
- Be patient. It may take some trial and error to find the best sanding technique for your 3D print.
By following these tips, you can avoid common mistakes and achieve a smooth finish on your 3D print.
