I tried to 3D-print a model car shown at https://www.thingiverse.com/thing:3246082
but I'm not happy about the way that the SUV come out. The sides of the SUV has "Stair Stepping".
1. Does anyone 3D-print a model car?
2. How to fix "Stair Stepping"?

1. Many people print parts and entire kits.
2. Putty.

What kind of putty is best?

I think for the car body shell you need to print it and then do some sanding to get rid of the steps, after that, copy the body by resin casting.

Putty is not mandatory:

To be fine, the body above is a resin copy of the 3d printed modified master, this one:

It is necessary to have a high quality print to minimize layering. Here's a project of mine that was done on a Form 2 resin printer. Not the same resin as casting resin. It was easy to finish.

Did it time ago with lancia ecv2. 3d Machine was the best available but to make it looking decently was a true nightmare taking months of sanding . Deeply prefer my way of today, with just minor parts 3d printed.
