Unless I just used a real expensive model of printer, the resin we used was 30$/liter, and with the amount it used for support struts it went a lot faster than you would expect that volume to go. The first thing I did was print a bunch of ork boyz i found a 3d file for and they worked out to 45$/10, which is more expensive than the GW
kit that comes with extra bits, to say nothing of grabbing them secondhand off ebay.
I've been printing in resin for a few years now, and I was kind of curious by this story. You said it cost $45 to print 10 Ork Boyz, and the resin was $30 a liter, so you used a bottle and a half, yeah? I've printed off an enormous Scythed Hierodule
- 8 inches long, 7 inches wide, maybe 5 inches tall - for maybe half a bottle, and done a whole ton of Battlemechs
that are 5 or 6 ounces each, but I've never printed Ork Boyz, and don't know what their volume is. So, I did an experiment.
I got a tumbler and filled it half full of water, and marked the fill line with tape. Then I chucked in 10 Ork Boyz: legs, a choppa arm, a shoota arm, and a head, times ten. I marked that line, too.
Then I poured off this displaced water to see how much volume the 10 boyz parts displaced. I poured it into a 2 ounce cup. I didn't measure this, but I'd guess it's about an ounce.
So, I have to say - I am stumped. Like I said, I've been printing for a few years now, both in resin and in FDM. I am very well versed in how much support material you need and how supports work. There is literally no way I can think of that you needed one and a half of these bottles of the left to fill the volume of the cup on the right:
I mean, I'm not saying you just made it up
, but it's the only explanation that makes sense to me. Maybe there is something I didn't consider: Did you make the supports solid bars an inch thick and elevate the boys to the top of the Z for your printer? Did you put the boyz on top of a solid block of resin 7 inches thick? Is there a crack in your screen, where the printer works, but it leaked out 45 ounces to print 5 ounces? Truly, I wish to know.
