Anyone else here have a  DaVinci Duo 2.0 that XYZPrinting is refusing to replace the old style print head so that it can print 
PLA, like they advertised it could?

I'm making a site that people can share 3D models and work together on a single project (using git so you can fork, cone, commit, etc...)

I've noticed that a big issue with "thingiverse" and "youmagine" are that they have a lot of pointless thing and when you try to find a thing for a real application its not there. So alone side sharing I want to add a service where you can pay someone to model things for you and if you want (get a discount) that file becomes pubic so that other people have quick access to real helpful things in the future.

what does everyone think? give me feedback on ideas, I'm doing this for #startupweekend  and plan on continuing it after as well. so give ideas if you have any!

Where does the discount come from? The site waves its fee for the transaction? It would be unfair to ask the modelers to be paid less for OS work; their workload doesn't change.

So im looking to build a large printer... Over 300mm... What printer would be good? What can i do that is cheaper?

Hey all, I've outgrown 123d design and I'm in the market for a new design program (I love my slicer, Simplify3d so I'm good there). Most of my modeling is mechanical stuff and goes straight to the 3d printer. Right now I'm looking at the free versions of Fusion 360 and Designspark Mechanical  and the $99 version of  3d Coat .    Anything else I should evaluate ? I did try blender at one point and ended up kicking my dog afterwards (jk)

Thanks guys,   based on feedback I'm going to prioritize testing out fusion and onshape, then give design spark and freecad a shot.

Decided to download the Thingiverse mobile app. Man, not only is the site crap but the app is even worse. THERE IS NO DOWNLOAD BUTTON FOR OBJECTS. That's right, they only have a "send to makerbot" button, making all objects technically proprietary out of sure bitchiness.

To be expected I guess.

+Brook Drumm I might actually consider paying for simplify 3d if it had some decent auto-support generation.

Curious to learn what strategies maker spaces are using to manage and oversee ten to twenty 3D printers. Are networked 3D printing solutions available? What is the current state of the art hardware/software?

Tell me if it's just me:

You get so fed up with some aspect of your printer, that you embark on the process of upgrading the part that's causing problems, only for the printer to turn around and start working perfectly while printing the replacement parts, causing you to wonder if you really need the upgrade in the first place....but heck, you've already bought the vitamins, and you're 90% of the way there, but gosh, I hope I'm not trading one set of problems for another. 

I need a beer.

Both my Printrbot+'s are essentially frankenbots, and I'm getting close tearing the first one apart to use its parts to build a more serviceable RepRap design (read: easily accessible zip-tied bearings for easy replacement). I really want to build an Ultimaker-inspired Eustathios, but that may come later. For the rebuild I will probably just use the Misumi 20mm aluminum extrusions I already have and, unfortunately, keep the horizontal moving bed design. I say unfortunately, because I feel horizontal bed motion is fundamentally flawed compared to vertical, but I want to keep the changeover simple. </mildrant>

Scaling down models is so useful in the early days of designs. 
Those Minecraft (tm) tools I printed were really a big hit (with the kids) but they were quite big - The shovel came out at about 96mm (3.75 inches) - so you can imagine the charms were a bit too big for a keychain - about do...

This is result of the same scaling law that explains why elephants don't look like big mice. Linear size increase or decrease changes the surface area by the square, and the volume by the cube.

If this ever happens to you... Give your printer a break until you get a new one! I don't know how much aggravation I went through trying to get it to print!

I changed to the rigid Z coupler today and it's back to printing like it always does!! Amazing!!!

Now I leave for vacation for a week! I don't know whether to be sad that I can't print or be happy I'm going to Puerto Vallarta for a week!!!!!

For those who can't physically make it to TechShop San Jose, we'll be live on Google Hangouts as well. The first 2 hours will be an introduction to SLA 3D printing with a live printing demonstration and Q&A intended for those new to the field. The next 2 hours will then be dedicated to discussion, technique sharing, and troubleshooting among existing Titan 1 users.
 
Live hangout for remote attendees to participate in the Kudo3D Titan 1 DLP SLA 3D Printer Meetup.

Details and agenda are available at:

http://www.meetup.com/Kudo3D-Titan-1-DLP-SLA-3D-Printer/events/221717589/
This Hangout On Air is hosted by ct. The live video broadcast will begin soon.

MJP is adding to the possibilities in additive manufacturing by mixing up to 14 material properties in one print.
To many, the 3D Systems’ ProJet 5500X looks like any other professional 3D printer, a large gray box with who knows what going on inside. But take a closer look and you will find a unique process that can do something no other 3D printers can do. Based on 3D Systems’ latest MultiJet Printing (MJP) technology, this printer can deliver accurate, high quality multi-material composites by fusing flexible and rigid materials layer by layer at the pixe...

So glad that my interests in 3D printing lead me to find Hugh Herr of MIT Media Labs. The work he is doing in lower limb prosthetics is incredible. Take 18 minutes to watch this video and be amazed.

So, I've been playing around with silly things with +Electra Flarefire, Mostly working on a "monster 3d printer" idea that sorta just, evolved from various sillyness that we've considered since Electra got their first printer...

The limitations of the Prusa i3, is mostly in size and speed, So me being the size queen that I am ahem I mostly decided to go for a Delta Printer that was large enough to print a 20 gallon bucket in under 1 hour, but small enough to be portable enough for transport in a moderate sized vehicle. 

Dimensions are, approximately 580mm a side, 1300mm tall. with 480mm long delta-arms. (actually, not  sure exactly what size arms I'll end up with, but something along that length is about right)

Given the Delta planform and the 400 step Steppers, it's only a natural that we'd end up using a Smoothieboard to run the printer, or at least, a higher end 32 bit processor microcontroller (Smoothieboard is the one we went with, because of, well, Cost vs Simplicity). The hot end will be an E3d "lite6" with a Volcano mod. Not sure exactly which nozzle size I'd go with, but thinking ahead, I Got the 4-pack nozzle set anyway. compared to the usual 0.25mm to 0.6m nozzles that come with most printers, the 0.8mm to 1.2mm set are positively cavernous, and necessitate the requirement that we run a direct drive style extruder.

It will be a bowden setup to keep the weight down, but I fear that when this thing is up to speed, there's gonna be a lot of inertia with it flailing about at high speed... Oh well. This'll be an interesting experiment for sure

+Jeff DeMaagd pretty much exactly that, if I was to do a cartesian machine of similar requirements I'd definitely look at a coreXY type. However, I feel that a delta is a somewhat lighter system in comparison.

Printrbot Simple Metal - I would like to put the wiring to the left of the stepper motor in a printable cable chain. The wiring only has to move in one direction. Has anyone does this before?

With a bit of thinking, you probably can design it so carriage and extruder are separate parts. That will give you the freedom to tinker with it later. But for a start, I think direct is better.

I've completed my review of all of the Inland brand filaments that are for sale at microcenter. 


TL;DR is that these are all very nice filaments that print consistently and cleanly with the notable exception of flexible.  I have a table of print settings on my blog to help get you started. I run all metal hotends and tend to run everything a little warmer than you might otherwise, so adjust accordingly. 
A few updates: as I've continued to tune my printer I've been able to speed up printing with these materials significantly. I've added ranges to reflect that. Microcenter has some amazingly good pr...
