Your printer is only "within wired distance anyway" partially because it needs to be babysat but mostly because it has to be. It has to be because most 3D printers are where [paper] printers were 15-20 years ago: dumb devices that need to be connected to a print server to do anything. The cool things that will come when 3D printers become wifi-connected are all the exact same awesome and freeing things that came when [paper] printers no longer needed to be connected to a "print server". Once 3D printers take that same step it's web-based configuration, uploading of jobs, etc. The Cube printer being wifi is a step in that direction, which is what I was blowing my wad about.

I look forward to the onset of poorly secured network-enabled printers, because some days I just NEED to print out 20 dildoes right in somebody's home.

I am really into the idea of dual extruder heads. Has anybody here had any success with that on a Pursa Mendel? If you have what extruders did you use and what hot ends did you use? Would you consider it a worthwhile upgrade for the cost? The reason it is attractive to me is that I print a lot of things where support is needed, printing the support in PLA instead of ABS would probably yield better results than ABS on ABS which never breaks completely cleanly.

On the reprap wiki about some of the things you might want to know about printing chocolate a printable nozzle and pump for pastes a syringe based extruder for many foods At the core of it most of the machine works fine, but there's plenty of room for improving the quality of nonplastic extrusion. Simple things can turn out nice though, if a bit odd. There's also some work being done for molten sugar printing. http://www.thingiverse.com/thing:26343 http://www.youtube.com/watch?v=9VHFlwJQIkE (okay yes, its being demonstrated in the biological context, but sugar is sugar)

Just emphasizing my irritation with the guys at solidoodle. I sent them an inquiry as I said in the first part of June and this was the response I got: "Our orders ship in about 6-8 weeks. We manufacture on demand, and we are working hard to get the orders out the door. Since your ordered in April, it shouldn't ship until late June." This was followed up by them me asking about the delay and them replying with the a shortage of parts they had ordered from a manufacturer, while the couldn't say if my order had been delayed because of that they assured me my printer was otherwise being assembled. So as bit of an update they posted in their blog (which I now check regularly) on July 10th to say that the FIRST Solidoodle has shipped. Dont think I'm going to get that late June ship date. I'm going to email them again today saying basically all of the above and see what they tell me this time.

Thats a bit disheartening. Sound like they really expect people to F5 their blog for real updates. Still thinking of getting one once they have a decent process going but I am holding off for now. The price is just so tempting Blackchamber posted:Just emphasizing my irritation with the guys at solidoodle.

Ok so like I said, I emailed Solidoodle asking why when I asked them why they thought I'd get a shipping notification at the of June when they knew that as of mid June they hadnt even completed or shipped even the FIRST order yet, much less an order numbered above 250. As if somehow even with the initial parts delay they would still be able to crank out, test, and ship a couple hundred of them in just two weeks. They emailed me back and said they were sorry if it 'appeared deceptive' to tell me June when they really meant they had no clue.

Solidoodle order 143 here, and the lack of communication has been surprising. Tossed $630 their way 11 weeks ago to the day, and not a single email saying they wouldn't meet their originally scheduled 6-8 week ship time -- or really, any email communication since the receipt. Seriously considering cancelling my order now and ordering a Cube 3D printer instead -- especially since there are suggestions that the serial number that Solidoodle did ship out was just a prototype, and they aren't actually shipping customer orders yet.

Internet claims its a Visa/Mastercard policy, though that probably is about as effective as the rules that were against no minimums purchase amount for a card. Interestingly federal law says that a merchant must inform you by mail, phone or email if they cannot meet a shipping date. http://www.ftc.gov/bcp/edu/pubs/consumer/credit/cre28.shtm

The reason for the policy is that you can't dispute the charge 30 days after it has been processed and get it automatically rolled back.

What photopolymer dlp printers are out right now? I recently saw a bank of them in a manufacturing context that was very, very unexpected and it looked slightly like the veloso's. I want to purchase one, I remember veloso was on indiegogo but these, while looking like something built by an engineer from a kit, didn't look like the velosos that I've seen photos of online. I know there are more out there than veloso being used. Anyways the resolution was loving stunning and I basically need one. Followup question, related.. small 3D scanners? Does anyone know about them? What kinds of small 3D scanners are there, are they all laser based or are there different types?

What are you trying to do? Most of the systems on the market right now are laser based, other than the Kinect I believe the cheapest on the market is NextEngine. Its rather slow like all laser based scanners. Other than laser line scanners 3d scanning can be done using structured light or stereo vision. I'm not aware of any inexpensive versions of either of these types on the market right now. If you want to experiment makerbot had someone working on it a while ago, take a look at this instructables. I also work for a company that is developing a 3d structured light scanner for consumer applications though thats a little ways off.

For prototyping/product design and other use, don't want a hobby/kit and my employer would be purchasing it. I've seen a few in fab labs and I don't know much about them so I'm trying to learn. The machines I've seen are the size of a projector themselves, but they're scanning mostly small handheld objects. Would those be laser? I'd like to mess around with structured light scanners as we have some nice cameras and projectors here.

Are you talking about the B9 creator? http://www.b9creator.com Go to the kickstarter for more info, this is pretty much veloso's except you can switch between 100 and 50 micron resolution and the resin used in the B9 is CHEAP. If you see the little Eiffel tower he made it apparently cost 10 cents in resin. He's filling out kickstarter orders now, or early august and then will have a webstore up to accept orders for more kits. Can't wait! Also if your production prototyping ever needs metal pieces, they did full burnout tests and the resin can be cast pretty much just like wax.

Creaform, artec and konica minolta all make laser based 3d scanners in the 5 figure range for industrial applications. For redesign you'll probably need a package like Rapidform (Nextengine has a slightly cheaper licensed version for use only with their scanner) to merge scans together, clean them up and create a model that can be used reasonably with a 3d printer (or a NURBS model for solidworks). 4ddyanamics has systems that consist of a DLP projector, machine vision camera and a dSLR bolted together on a tripod. And for shameless self promotion, my company does DLP based pattern projection and is faster than anything previously mentioned.

Didn't see this posted, but it looks pretty interesting: http://www.extremetech.com/extreme/133514-the-worlds-first-3d-printed-gun It's only the receiver at this point, but what are the chances that as 3d printing improves you will eventually be able to print the whole gun?

Lowers have already been done in plastic, even commercially (magpul?), although they break over time. You can't print "the whole gun." You can through various means additively print metal parts but trusting that with pressures of modern ammunition is a whole different ball game. BTW 3D printed gun parts is one of the big 3 "this may bring down 3D printing" things besides copying patented work.

Cavalry Arms makes polymer AR lowers, they are beefed up (as in thicker) at one particular stress point and they don't break over time. The lower receiver, as mentioned, is not a shooty/'splody part. Lowers have even been made from wood just to show it can be done. (Edit: In all cases we're talking about "stripped" lowers - it's just the "frame". The hammer, pins, spring, etc -- in other words, all the worky parts -- are all then installed into it.) It's still pretty cool; it's by no means printing a firearm, though.  don't tell the news people!

Without a soft rubber hopup bucking you wouldn't get a good airseal or backspin on your BBs. A metal barrel is pretty important for accuracy and velocity. Durability would be an issue too, even metal gearbox housings can be prone to cracking in high FPS setups.

I'm finally in the market for purchasing a 3D Printer, but I've been following them since the first one was pieced together years ago. The main printer I've been considering is an Ultimaker and I spoke to a (machinist) friend of mine about my interest in buying one. They're big purchases, as I'm sure any of you can relate, and it'd be nice to sort-of try before you buy. Anyways, he suggested I make a post towards the community to see if anyone would be willing to show me one, explain what they like and don't like, see the quality in person, hear how loud they are. I'm here to do that and try my luck. I'm up for seeing any of them in action, though. He was really avid about the helpfulness of the people who own them and after reading thousands of posts about the printers I couldn't agree more. There don't seem to be any active hackerspaces locally (around Tampa, FL at least, one kinda-sorta in Orlando). I have investigated the ones on campus (I'm a Senior Mechanical Engineering student at the University of South Florida), but a lot of them seem to be old, abused, and out of commission. I can drive a bit of a ways and I'd be totally up for compensating in lunch, beer, or both. fartingfool fucked around with this message at 06:04 on Aug 1, 2012 |

Saw a pretty cool video today on how one type of metal 3D printer works: https://www.youtube.com/watch?v=i6Px6RSL9Ac I don't think I've ever seen the bronze-infusing method from the video described before. I don't think that the small metal stuff you'd print at an on-demand service like Ponoko or Shapeways is quite so hollow.

Not sure what you mean by hollow, after the bronze infusion, the object is solid metal but it's a mixture of stainless and bronze. When Shapeways first offered the stainless material there were issues with consistency in the color. Some objects would come out very silver looking while others would look almost pure bronze and everything in between. I have a print I got done in the stainless material and it definitely has a bronze tone to it.
