  1. Work picked up and I had to take a break from this, but I had a little time this weekend to start adding some of the 3D details. Pretty reasonable improvement over the laser cut styrene details.
  2. Second round of printing went pretty well. No build plate separations but I did have one strangely formed part. Probably could have used an extra support there or something. So we now have a set of hold-downs and aft umbilicals for both Saturn Vs. Neat-o.
  3. First Print with the AnyCubic Photon Finally got the first print under my belt and it was a little bit of a success and a little bit of a failure. After leveling the build plate I set up 4 identical APS units and a set of aft skirt umbilicals for the S-IC and set off to printing. A couple of hours later the print finished and I was greeted with 2 APS units and the umbilicals. Two of the APS units were not there. After cleaning off the other parts I pulled the vat and poured the remaining resin back in the bottle. Found that the other two APSs had separated from the build plate pretty early in the printing process as there was only the beginning of their platforms. They were on the outer edge of the plate so I don't know if I didn't clean the plate thoroughly enough, or I didn't get it exactly level and the stuck to the vat early on. Not sure. After cleanup and curing I had these ... They came out better than I expected, especially the umbilicals. They're very thin and I actually think I could add more detail to them if I wanted. As you can see on the I did crack one pulling it from the supports. The APS units came out really well too. Here's the curing bucket I made from a Home Depot paint bucket and a strip of UV leds I got off Amazon. Worked like a charm.
  4. Keep needing to remind myself that this is 144th scale. Amazing work Manfred.
  5. It's like magic! Very well done.
  6. Finally found some isopropyl alcohol last night, so I might just get started with my initial prints this weekend. Still waiting on some parts for a UV curing station, but I guess I can use the Sun for curing the first few prints as they'll likely not be usable anyway. It will be nice to actually learn by doing rather than by theory. I won't be printing this engine bell but it is nice to know that a flat placement and larger supports will work. I was thinking cleaning supports from the inside of the bell would be far more difficult than the outside especially since I went bonkers on the interior with the regenerative cooling tubes.
  7. That might actually be the better way. I think the reason most print at angles is to mitigate some of the vacuum created when the build plate is moving up and down in the resin. This article, though about wargaming, seems to be a pretty good reference to some of the ins and outs. I keep referring to it ... and this thread here in our very own form.
  8. A bottle of isopropyl alcohol! My kingdom for a bottle of isopropyl alcohol! I'm still collecting some of the sundry items needed to start printing and I've found that a simple bottle of alcohol is a very hard item to procure. That and extra gloves. Seems there may be a pandemic ongoing. Meanwhile I've been digging into the ChiTuBox slicing software. It seems to be a little more robust than the supplied AnyCubic software. I've just be messing around adding stl files and running through all the options. I'm sure when I actual start printing it will be somewhat of a trial and error sort of ordeal. Messing around with a 1/48 J-2 engine bell. Hey look, SUPPORTS!
  9. Congrats on the Elegoo. I had the very same issue with the Treasury when I brought mine home too. Funny how universal that seems to be.
  10. This is precisely the reason I decided to just go ahead and bite the bullet and buy a printer. Relying on Shapeways' ever-changing production policies and pricing has always put me off. I know they're a business but it seems that if you make it increasingly more difficult for your customers to afford and utilize your product, you might be doing something incorrectly. Now that I can produce my own stuff all that stands in the way is consumable costs and time. It's very liberating.
  11. The Photon arrived yesterday. Really only had time to pull it out of the box and check out the contents. For the price, the build quality is amazing. For whatever reason I thought these came with a 500ml bottle of resin – this one didn't. Just ordered a bottle of grey from Amazon, so maybe by this weekend I can start messing around with this thing.
  12. I've been digging through every resource possible, taking copious notes. Hadn't heard of the FB group, I'll definitely check that out. I figure I'll start out with something rather simple and build on that. Probably these guys. S-IVB APS units
  13. The printer should be arriving this week, needless to say I'm starting to get very excited. The term "game changer" keeps popping into my head. Let's hope it's just that. Got the fins and the new tie down parts modeled. That just leaves the aft heat shield that I need to re-work for the new F-1 engines. There's a lot of stuff yet to do.
  14. I think I have these about where they’re going to be. A little simplified here and there for printing ease but I think they're looking ok. I'm sure there will be some fine tuning when it comes to printing. Working on fins next.
