I’ve never 3d printed anything but know a lot is possible now. Still I believe you’re going to have to do all that cleanup work to smooth it out, right? The casting I was referring to is taking a good original part and making a mold off it in silicone, then cast with plastic resin

 

I always think metal. I was thinking wouldn't it be way to heavy but then I remembered aluminum would be pretty light and dope. It all depends on what you're prints look like. If I was printing things like above I wouldn't think twice about casting it in sand straight out of the printer. The vent would probably need redesigned to cast. Might be a little to thin to flow and would cool before it filled.

 

Test print fitment.

Painted them a matte-ish black. Not too shabby for free. If there's any interest on here I'll try to figure out a way to share the CAD file on here.

 

You can do mega but I think it only stays up for so long.
