UPDATE: We’re getting a LulzBot thanks to [Jeff Moe].

ALL DONATIONS ARE BEING REFUNDED. YOU WILL STILL RECEIVE YOUR STICKERS.

We’ve held out for far too long. Hackaday now needs a 3D printer.   We get emails all the time asking why we don’t have a donate button. Well, we’re kind of stubborn and would rather just do with what we have. Unfortunately this hasn’t gotten us very far in the 3d printer department.

We have a few projects in mind that could really utilize a 3d printer, namely building custom game controllers for children with special physical needs.

If you have any interest in helping us get a 3D printer for Hackaday, read on. Otherwise, carry on with your day.

[Prusa]’s Nozzle Prints Polycarbonate, PEEK, & Nylon

November 27, 2012 by 42 Comments

Oh, we’ve been sitting on this one for a while.

[Josef Prusa], brainchild behind what is probably the most popular 3D printer, has just unleashed a new hot end that is capable of printing objects in polycarbonate, PEEK, and nylon.

This new hot end is completely made out of stainless steel – there are no plastic parts made out PTFE or PEEK to keep the heat from transferring up to the extruder. Because the Prusa Nozzle can print these plastics, it’s also now possible to print parts for other hot ends such as the J Head and the Budaschnozzle.

We ran into [Prusa] at NYC Maker Faire a few months ago, and he was kind enough to go over the advancements in his new nozzle and new i3 printer. So far, it looks like the lack of a PEEK insulator isn’t doing the new hot end any harm – [Prusa] has left molten plastic in the nozzle for a few hours and nothing bad has come of it.

You can check out the interview below.

Again, thanks to [Prusa] for granting us an interview and providing some free advertising for Hackaday’s hosts for the NYC Maker Faire. Before you complain about the delay in getting this interview out to you, don’t worry; I slapped a few Makerbot stickers on the back of [Prusa]’s jacket. Everything’s cool.

Octopus Submarine Is Something Out Of [Jules Verne]’s Imagination

October 4, 2012 by 11 Comments

Making an octopus on a Reprap or Makerbot isn’t that terribly hard. There were dozens of these octopuses at nearly every Maker Faire booth with a 3D printer. These octopuses have almost become a right of passage for new owners of 3D printers, and serves as a wonderful reference object on par with the Utah teapot and the Stanford bunny.

[Sean Charlesworth] wasn’t happy with any old octopus; no, he had to build a better octopus, and what better way to do as such then to make a steampunk and [Jules Verne]-inspired model submarine?

[Sean]’s Octopod underwater salvage vehicle was almost entirely printed on a very expensive printer. Save for a few LEDs, electronics, and armature wire, the entire model sub/octopus was printed on an Objet 500 Connex printer.

The Objet is unique among most 3D printers in that it can print objects made of several types of materials. In [Sean]’s show and tell he showed me how the tentacles were made of a hard plastic material and a bendable rubber material. [Sean] put a piece of wire through the length of each tentacle so he could pose the Octopod in just about any way imaginable.

The hull of the Octopod is an amazing amount of work. The cockpit features miniature controls, an illuminated display for a very tiny pilot, and even moving parts that include a mechanical iris in the recovery bay, a winch that works, and even doors that open and close.

[Sean] put a bunch of glamour shots of the Octopod on his web site along with a few videos of the construction process. You can check those videos alongside my interview after the break.

Finally, An ARM-powered Arduino

October 3, 2012 by 70 Comments

Far removed from the legions of 3D printers featured at this year’s Maker Faire in New York was a much smaller, but far more impressive announcement: The ARM-powered Arduino DUE is going to be released later this month.

Instead of the 8-bit AVR microcontrollers usually found in Arduinos, the DUE is powered by an ATSAM3X8E microcontroller, itself based on the ARM Cortex-M3 platform. There are a few very neat features in the DUE, namely a USB On The Go port to allow makers and tinkerers to connect keyboards, mice, smartphones (hey, someone should port IOIO firmware to this thing), and maybe even standard desktop inkjet or laser printers.

The board looks strikingly similar to the already common Arduino Mega. That’s no mistake; the DUE is compatible with existing shields, so connecting a RAMPS board for your 3D printer should be a snap.

Here’s a PDF the Arduino and Atmel guys were handing out at their booth. A few DUE boards have already made it into the hands of important people in the Arduino community, including 3D printer guru [Josef Prusa]. Sadly, the folks at Arduino didn’t think media personalities needed a DUE before its release, so you’ll have to wait until we get our hands on one later this month for a review.

And then Obi-wan said, “you were supposed to be the chosen one!”

Yesterday, a little bird told us Makerbot will be moving to a closed source model for their newest printer. This was confirmed, and now [Zach Smith] a.k.a. [Hoeken] – creator of the RepRap Research Foundation and co-founder of Makerboth Industries is weighing in with his take on the situation.

Hey! Free stuff!

Remember that DIP28 ARM chip with BASIC? Remember how I told you Coridium will be giving a few hundred away as samples? Yeah, that’s happening now.

Replacing a scroll wheel with titanium

[Rhett] has been using a Logitech mouse for a few years now. Recently the scroll wheel became corroded, so [Rhett] replaced it with a titanium version. The perfect match for the trusty battle axe, theIBM Model M keyboard.

Web-based IDE for the Raspi

[Phil Torrone] sent in a video of something he and [ladyada] are working on. It’s a web-based IDE for the Raspberry Pi. We’ll do a full review of this when it’s released.

Intro to software defined radio

So you have one of those TV tuner dongles and want to get in to software defined radio. Where do you start? [Al Williams] over at Dr. Dobbs has a great introduction to SDR, and gives a few pointers that should help you get that cool looking waterfall plot very quickly. Thanks for sending this in, [Chris].

Makerbot, Occupy Thingiverse, And The Reality Of Selling Open Hardware

September 20, 2012 by 150 Comments

Yesterday, Makerbot Industries introduced the Replicator 2, a very good-looking 3D printer that will is probably the closest thing we’ll see to a proper ‘consumer’ 3D printer for a year or so. There’s only one problem. The new Replicator 2 is rumored to be closed source. If that’s not enough, [Bre Pettis], co-founder and CEO of Makerbot Industries will be speaking at the Open Source Hardware Association conference next week with the suitably titled talk, “Challenges of Open Source Consumer Products.”

Of course, the Replicator 2 being closed source is hearesay, and we can’t blame them for closing up parts their product; they have investors to worry about and people are blatantly copying their work. There was another change in Makerbot’s operation at the press conference yesterday: Makerbot now owns everything you’ve put up on Thingiverse.

This news comes from [Josef Prusa], creator of what is probably the most widely used 3D printer in the world.

[Prusa] begins his rant with the history of the RepRap. The project began with a team of core developers headed by [Adrian Bowyer], and supported by [Zach Smith], [Adam Mayer], and [Bre Pettis]. [Boyer] gave the guys a bit of money to start Makerbot, and it’s something the guys at Makerbot have never been ashamed of. Makerbot went on to create Thingiverse, became the darlings of the Open Hardware movement, and acquired $10 million from investors.

All things change, of course, and Makerbot is no exception. Along with the (again, rumored) closed-source Replicator 2, [Prusa] pointed out the Terms of Use for Thingiverse say that Thingiverse – and thus Makerbot Industries – owns everything submitted by Thingiverse users. [Prusa] started an Occupy Thingiverse movement in response to this discovery.

Honestly, we hope [Josef Prusa] is wrong on this one. We hope the specific clauses in Thingiverse’s Terms of Use granting itself a license to do whatever it wants with uploaded Things is just a bunch of legal mumbo jumbo added in by lawyers to protect Thingiverse from being sued by crazy people. Still, if rumors are true, it may be a portent of things to come.

In any event, [Prusa] will be taking his Thingiverse things down. He plans on posting his stuff on GitHub, probably the most Open Source-friendly community in existence. You can do the same with this GitHub template for 3D printed objects.

So, learned reader of Hackaday, what do you make of this? Is Makerbot right to close up their projects? Are we finally becoming disillusioned with Open Hardware? What say you?

Making Plastic Filament At Home

September 14, 2012 by 44 Comments

There’s one problem with the popularity of plastic-extruding 3D printers such as the RepRap and Makerbot; since they’ve become so popular, the price of plastic filament has skyrocketed over the past few years. Without a way to produce filament at a hackerspace or home lab, the price of 3D printed objects will remain fairly high. Project Spaghetti hopes to rectify that by building a machine to make plastic filament for 3D printers.

The folks behind Project Spaghetti – a loose amalgamation of makers going under the title of Open Source Printing, LLC – have successfully built a machine that is able to produce short lengths of plastic filament.

Early machines used a plunger to press small pellets of ABS plastic through a heated steel pipe to produce filament. There are a few problems with this approach, especially when the temperature is set to 480F, but the team was able to make a bit of filament with this design.

Although the team is using a piston to force melted plastic out of a nozzle, they do have a screw-drive ‘plan B’ in the works. This design should allow for continuous extrusion for theoretically endless reels of plastic filament, every RepRappers dream and a neat way to win 40 grand.
