Here’s an example of the process on how these MJF/SLS prints are smoothed out. It’s not difficult but it’s obviously a little tedious to anyone whos impatient (I’m guilty at times of this myself).
It only takes a couple coats of primer and my favorite is definitely
Krylon primer. Not the primer and paint in one but the full on primer. It goes on thin but it also dries super fast and doesn’t seem to clump together.
I very much DISlike “Rust-oleum” primer as it doesn’t seem to fully dry (or it takes forever to do so) and it’s thick so it ruins small details that’s within the design itself.
Here’s some pics of this process. This is the top of the mount where the weaver sits. Simply prime, sand and then reprime. Again each coat of primer dries extremely fast so I can add about 3 coats within 30 minutes from when I start. As long as the sun is out I’m good to go. Then once those coats dry I’ll use 400 grain sandpaper and it doesn’t take that much sanding. Smooths out pretty quickly. After which I’ll add the the finishing coat of primer. Just one coat this time. I’ll probably go over this with 800 grain sandpaper to flatten it tight once it’s dried and it should be good to go..
There is a LOT of parts so it’s a little time consuming obviously. This is where it becomes tedious BUT being that I’m obsessed with detail/accuracy and chose to design it with so many individual parts to get there..
That song
JUST by Radiohead plays in my head every time I get to this stage!
But this type of sanding I also find strangely therapeutic as well so..
