This past year I began printing with a Creality Ender 3 and a few months later I purchased the Anycubic Photon. Both have been amazing. I can so very much relate to working intensively on a project, only to find out later I've made such an obvious mistake or a miscalculation. So far, the printers have been used on an S scale project for a local lighthouse heritage organization. I printed the lighthouse and many other features for this diorama. But now I have the opportunity to use them for the layout! I'm modeling circa 1950-55 SP Tillamook Branch here in Oregon in HO. I will need the F-70-7's to haul lumber. I'm also hot on the track for something to use to haul wood chips. I've seen the Red Caboose sugar beet gons but understand they weren't used for wood chips on the SP (?). SPH&TS is sold out on the F-70-7's. I am drawing using FreeCAD, which is quite painful, but with remarkable options. I've managed to work through some of the hard parts. Anybody out there using FreeCAD...let me know, it would be good to collaborate! Thanks.

That resin is much less viscous, it might help build this car flat and without supports. If you can put small "bleeder gaps" in the outer ends of the ribs in the under side, it might relieve the pressure so it doesn't distort the sides. The lower edge of those ribs could still connect to maintain rigidity. I think it's worth a try, if it works, it could cuts down material use and build time by half or more, with minimally perceptible changes to the built part.<br /><br />I'm willing to use my material for this kind of experiment if you're interested making a test alteration to the model, and I can send you macro photos of built parts to show how it turns out.JDM929https://www.blogger.com/profile/04564871886719684186noreply@blogger.comtag:blogger.com,1999:blog-3912308714924865824.post-81824164780153263002014-12-02T17:02:25.220-08:002014-12-02T17:02:25.220-08:00BTW, note that different versions of the PreForm s...BTW, note that different versions of the PreForm software will generate lighter or more robust support structures. The photo above shows something printed with version1.4 or so; version 1.6 would try to support the whole width of the model.Robert Bowdidgehttps://www.blogger.com/profile/14155962656525181088noreply@blogger.comtag:blogger.com,1999:blog-3912308714924865824.post-75389553294534114472014-12-02T17:01:19.989-08:002014-12-02T17:01:19.989-08:00I tried both 30 degree angles and 45 degree angles...I tried both 30 degree angles and 45 degree angles with the CS-35A with good luck (60 - 0 - 45 for x, y, z). The support nubs always attached to the pockets because they were the first elements to be printed. I sometimes broke the stake pockets when cutting the support structure off. I had less problems when I cut off the support structure right after printing (while the resin was still a bit flexible). I also found my PBL despruing nippers (which look more like tweezers with inside knife edges) could do a gentler job than side cutters.<br /><br />I really prefer printing models flat on the build platform if possible, both to cut printing time and to get a clean surface. However, I can only do solid objects that way. When I printed the flat cars flat, I'd get blowouts - hollow gaps or bits where the pressure of the liquid resin would break an enclosing wall. This usually messed up the side frame of the flat car.<br /><br />If you try printing the 36 foot flat car on Shapeways, let me know how it comes out on your printer!Robert Bowdidgehttps://www.blogger.com/profile/14155962656525181088noreply@blogger.comtag:blogger.com,1999:blog-3912308714924865824.post-73390901035778474042014-12-02T16:29:56.184-08:002014-12-02T16:29:56.184-08:00I happened to find your model just looking for thi...I happened to find your model just looking for things to resin print. I happen to have a Form 1 as well, and I'm curious what orientation worked well, what angle from horizontal to avoid the support nubs from giving you a hard time with the stake pockets and other details.<br /><br />Thanks.JDM929https://www.blogger.com/profile/04564871886719684186noreply@blogger.comtag:blogger.com,1999:blog-3912308714924865824.post-8302147084440811012014-09-27T17:47:55.104-07:002014-09-27T17:47:55.104-07:00Hi, Karol,
