helopticor posted:Thanks Doc Hawkins and techknight for your other suggestions, but OpenSCAD, which Videodrome mentioned, was exactly what I was looking for. I just wrote down coordinates of vertices and calculated which triples of vertices correspond to triangle and then I got my STL file which I can then send to the people with the Makerbot. I just did my own first OpenSCAD project on Saturday - it's so easy! I'm going to write a post on the Ponoko blog about it tomorrow. I was totally intimidated by the source files I'd downloaded from other people on Thingiverse but you really do just start with a simple couple of shapes and build up!

Ugg boots posted:Are the three printing services listed in the OP (ShapeWays, Ponoko, The Game Crafter) still the main 3d printing services to check out? i.materialize is the third main 3D-printing-and-more-on-demand service. They do some serious poo poo. They 3D printed The Thinker to help repair one of the statues that was stolen and hacked to pieces for scrap: http://i.materialise.com/blog/entry/3d-printing-rodins-thinker (The Game Crafter doesn't really count, it's just neat.) I recommend Ponoko by default just because I write for their blog, but I haven't actually printed anything with any on-demand service yet. I just did these replacement analog sticks on my MakerBot (and wrote a post about them) but I was thinking of trying them on Ponoko to make them smoother:

Videodrome posted:I've been eying that model since it was posted. I'm glad to see someone built it. How firmly do the sections hold together? They don't look exactly flush to one another. Yeah, they hold together well but I'm going to need a dremel to shave down the connectors enough to get the pieces flush. Some of the other finished examples look completely flush, but I'm not sure whether that's due to post-processing or whether they had a stepper-based extruder or what.

Same Great Paste posted:Anyone with a printer, talent, and boredom feel like doing a stupid commission? I'd really like a sugar-cookie cutter that's dog-bone shaped and stamps "Scooby Snack" onto the top. To not poo poo up the thread, please PM me. (Willing to pay actual money. I understand that this costs your time, mental energy, materials, machine wear and tear, shipping/handling, etc...). That might be a fun project. I should warn you though, I don't think that you'll get that much text in the cookie cutter. The letters would need to be really thick and widely-spaced to come out legibly, not just because of hobbyist printer quality, but also because you want there to be a legible impression made into some dough. If you're willing to forego the text entirely, there's a Win/Mac/Linux app specifically for making cookie cutters for 3D printing: http://www.local-guru.net/blog/pages/cookiecutter-editor But if the project is unappealing without the text, you'll likely pay simply for the design and then upload the file to Ponoko or Shapeways where the design will be professionally 3D printed (in metal if you like) on-demand.

Big freakin' news: MakerBot is about to release a new dual-head extruder for multiple colours or materials in a single print. Holy poo poo. That means you can use water-soluble support material to print complex stuff with overhangs and then wash it away from the final object.

Ahh, sounds quite a bit more experimental than I was hoping.  Not sad about 3mm going away, people keeping that and 1.75mm filament in stock was never going to last.

Mister Sinewave posted:But for support structure? Isn't that really a software thing? Get "snip-offable" automatic support structures going first, then worry about loving making them water-soluble or whatever the hell with the second extruder. Well, ReplicatorG actually does this if you turn on "exterior support" during skeining, but the problem with same-material support is that it's a pain to remove: (Even when you set it really thin.)  (click for huge)

Hillridge posted:I know this field is rapidly evolving, but if you had to get a printer today that you felt had the best performance/price point, what would your top choice be? I'm completely open to kits that require assembly. I would look at the Thingomatic, Ultimaker, and Mosaic. They have differences, but all are quite capable and offer some amount of official support during and after your build. At the moment it would be a tough choice for me between the dual extruder support on the ToM and experimental extra-tall versions of the Ultimaker or Mosaic. Mister Sinewave posted:I upgraded to the latest ReplicatorG (which I avoid because I have to re-tweak all the customizing I did in the last one and am not determined enough to figure out how to make my settings portable) to try this feature out! Wow, that's.. weird. Maybe try turning on interior support too?

Mister Sinewave posted:Also, sadly despite blowing hot air into the build area and insulating it with foam (so it remained nice and toasty - but not HOT - inside) my last tests STILL show signs of lifting and curling (and therefore distortion and added stress on the print nozzle) during tall prints. I'm out of ideas so I guess I'll just shrug my shoulders on that one for now. Have you played with the height of the nozzle at start? You can set it low and really mash that bottom layer into the surface to get some good stick.

SynthOrange posted:Would be nice if eventually down the line you get a home plastic recycler to chuck in all the scraps, bits, misprints, unused prints and packaging into, then have it squeeze out a new spool of plastic, ready to go. From what I understand, the conditions necessary to recycle and re-extrude ABS at an accurate 1.75mm is not practical/safe outside of industrial settings. I could see having a bin for commercial composting of PLA, though.

Lyric Proof Vest posted:I really like the idea of a 3d printer and will prob be getting one in the not too distant future (qualifing as a doctor in ~6months). In the mean time what would people suggest as the best way of getting parts i want for small projects printed. Join a hackerspace? there's one in London with a makerbot or are there websites where people print stuff for you? Yep, Ponoko and Shapeways like SynthOrange says, but you should definitely still check out your local hackerspace. Some advice: I'm not assuming that you would do this, but don't just walk in demanding that someone print your stuff. Check out an open house night, bring some beer, hang out, get to know people, etc. We've had that happen at our space before, where a new person insists on using the laser cutter ASAP without wanting to be part of the community, and that's not really our thing. For the on-demand stuff, I just got my first order from Ponoko yesterday. I make Space Invader plugs for stretched earlobes on my MakerBot but now I'd like to sell some original designs that don't violate copyright:  On the left is done in two pieces in red ABS (one for the invader, one for the plug, then fastened together). On the right is a single multi-colour piece in ZCorp's proprietary ceramic powder.

Videodrome posted:Also, it looks like the Automated Build Platform was a pretty big failure. Makerbot isn't even including it in the ToM kit anymore, though you can still buy it separately, but the price has been cut in half. I think that the normal kit still comes with it but that the custom pre-assembled one only has the non-automated one. The ABP belt never worked right for me, so mine is just a plain HBP now.

Spent all morning dicking around with this bastard, resets and reboots and re-priming extruder all to no avail. What's wrong? Who knows? Idler wheel not tight enough against the filament? (Not sure which extruder you have.) Loose wire losing contact during movement?

YardGlass posted:That looks awesome. Roughly how long did it take to print that, and do you really have to watch it the whole time? I would print trophies for *everything* if I had one I think. It actually was only about an hour an forty mins, I just watched a recent Wednesday Night Fights while it printed. In general you don't have to sit and stare while something prints, assuming you have a spool of filament that doesn't need tending to, but I think of it way: do I want to go on a long walk while a balsa wood box is melting plastic at 220 degrees in my living room? So.. Trips across the street to the convenience store, no biggie. But I'm not going to leave for the day while something is printing. I've had a 7+ hour print (one of the human torso statues, wide and tall the whole way up) die 30 mins from completion because a stray cable caught on something while I wasn't paying attention.

You basically just get to know the sound of your printer. The snag was due to a bit of wood broken when I installed a power supply where the switch didn't line up with the holes, and the extra long cables I added when installing the z-axis extender.

Z the IVth posted:In any case, I thought it would probably be feasible for me to make a physical master, scan this into a 3D model, and then proceed to add the fine details there. The main question at this point is whether I would be better off sending my stuff to a company for scanning, or attempting to construct my own scanning rig. There's only so much that you're going to get out of a hobbyist solution, so if you need fine detail and accuracy you might want to send your stuff out. Other hobbyist scanning projects: Fabscan - http://blog.ponoko.com/2011/12/19/fabscan-open-source-3d-scanner/ Spinscan - http://blog.ponoko.com/2011/08/18/spinscan-the-3d-printed-3d-scanner/ Have you considered modeling from scratch on the computer?
