In this video I show you how I smooth, fill, sand, and finish 3D printed parts! This method also works for any application like car parts, 3D printed models, cosplay accessories, etc.

The post processing of 3D printed parts can be different for certain materials but this should work on most, if not all materials. In this video I am using a Nylon/Carbon material from Matterhackers. The key to this process is the Bondo glazing putty that will fill all of your low spots. The sanding stages smooth out the Bondo and eventually you are left with a very smooth surface with very few imperfections.

A few coats of buildable/sandable primer and you are ready to use these parts on your car! The process also seals the plastic from water/chemicals that you would use to wash your car.

I've had my parts installed on my car for several months now and the sun has not warped them, and water has not damaged them. This is great for one off parts that you are experimenting with!
