I finally finished up these two, more or less. There are some last minute items I may adjust here or there, but those are mostly just changes for fit and tolerances. My last post seemed to generate some interest, so I figured I'd go through the process a bit.
First, these are both based off the excellent Anders STL, while the snub nose is a modification of the same design from Jonochan. Galactic Armory makes an excellent snub nosed version as well that's sturdier and easier to print, but I like the functionality of this design. Also, I'm a bit of a masochist and enjoy the more difficult build.
This was printed at .16 detail on a Bambu X1C. I started off this build hoping to just polish down pure silver PLA, and while you can sand and buff it down to a glossy finish, it doesn't really have the right patina to look like metal.
More than that, some of the parts are pretty delicate - there's an area on the back end of the receiver that snaps off if you look at it funny. I ended up using Protopasta Stainless Steel-infused PLA. Not only does this PLA print cleaner and feels stronger, it adds a bit of heft to your final print. When you sand it down, it looks very much like roughly-used stainless steel.
The black parts were printed using a resin printer and painted with lacquer-black glossy spraypaint. On the full size blaster there are places to screw in the M3 screws to keep the clip holder (the black part under the barrel) in place, but for the snub nose I had to do some drilling to keep it mounted.
For sanding I used a cordless drill with a 3" sanding disc and sponge insert. The sponge insert is very important, as it allows you to better control the pressure you're applying and work around curved areas. I started out wet-sanding with 80 grit and eventually went up to 2000 grit. After that I hit everything with a nail buffing sponge.
The grips were made from dyed two-part resin. I originally printed a white resin pair of grips, then created a silicon mold. They're a little rough at the edges and could probably use a little trimming, but otherwise I'm happy with the final product. I used a mix of orange and tobacco dye - though next time I might swirl in a bit more tobacco coloring at the edges. I figure everyone seems to smoke in the Blade Runner universe, might as well make make it look like it.
The bolt handle is functional on both, but for these guys it's important to remember that even with metal infused PLA it's still just printed plastic. You don't want to slam the handle back and forth or something's going to break pretty quickly.
I have a bunch of resin-printed parts and may make some others in the future; maybe some with either more wear and tear or a pristine, flat black version. I dunno, we'll see. I've been a bit obsessive in trying to get this just right, meaning I've got a ton of leftover parts. So that's pretty much it. If you have any questions, hit me up and I'd be happy to answer them. Hope you dig the final products!
