I started a thread on hackerspaces yesterday, and thought it deserved a mention here. We have a half finished rep-rap at our space that we hope to get up and running as soon as we're done moving and actually have time to work on it.

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.

techknight posted: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. Thanks for the advice. I just found out tonight that one of the members at my hackerspace who built his own CNC milling machine is also almost done with an extruder head for it. I'm going to help finish that and with some luck we'll have our own custom, super precise and badass looking printer.

We have a Replicator 2 showing up at the space Friday!  Can't wait to start messing around with it.

I've been absent from this thread for the last 2000+ replies, and only tangentially involved in 3D printers at my hackerspace. However, this week we picked up two donated Zcorp 450 machines complete with 200lbs of consumables, and I have been experimenting a lot with full color prints and 3D scans (I have a 3DSense). I've been printing creepy miniatures of members and friends, but am also looking for pre-made models. Other than the native *.zbd files it prints, the best import format I have found is *.ply. Is there a good source of free models in this format, or an easy way to convert 3ds or whatever files into *.ply?

The printer's software can convert STL to ZBD no problem, but STL don't carry color data, so they are a bit boring to print. Most full color models I've found are in something other than PLY though.

techknight posted:Whoa, nice! Photoshop CC is decent for texturing 3D models nowadays if you want a reasonably familiar interface. Thingiverse has a limited amount of colour stuff, but the photogrammetry tag will show some decent stuff with textures. Thanks for the tips, I've gotten decent with the 3Dsense software, but it is kind of lovely. I'll give Skanect and Recap 360 a try too. The machine has a built in depowdering station on the right with a downdraft table that helps to keep the dust well contained. We have a fume hood I plan to use when infiltrating the parts. So far we've just tried tubes of generic superglue and the results are ok but not stellar. I'm looking forward to trying the CA you linked if I can find it for sale.

techknight posted:Are you infiltrating right after depowdering? If you use rough sandpaper or a dremel you can get much better colour if you go over the parts with that (but don't sand/dremel inside of the depowdering booth of course, that's what i suggest a separate downdraft table for). That looks really good! What dremel heads are you using? I'm ordering a bottle of the infiltrant you recommended, and we're already on the hunt for a crockpot to do wax dips. How much of the final quality is dependent on that sweet scanning setup you have?

Is that a full custom rig? I've only been experimenting with the sense and its software, and the colors are kind of meh. I need to try something like recap 360

techknight posted:The one at work is, yeah - ~150 DSLRs with custom electronics/hubs to deal with all that data every time a shot is taken. (it turns out that plugging in a hundred and fifty USB anythings is a non-trivial setup We're working on a plan to do something similar with a bunch of old android phones. When you're sanding the models, do you just hit the large, flatter areas? I haven't tried yet, but I imagine it's tough to get in all the nooks without destroying things.

Anyone have a vibrant color model similar to this: https://www.shapeways.com/blog/archives/1896-awesome-3d-color-prints-from-nervous-system.html preferably in *.ply format, that I can use for a test print?
