Opening up the settings in MakerWare

ProfTweak

[Rich Olson] really likes MakerWare and the Makerbot slicer – the software package that comes with every Makerbot – but sometimes he needs to change a few settings. Makerware doesn’t allow the user access to 90% of the setting for slicing and printing, so [Rich] did something about that. He came up with ProfTweak, a tool to change all the MakerWare slicing and printing parameters, giving him precise control over every print.

ProfTweak handles common settings changes such as turning the fan on or off, adjusting the filament diameter, changing feed rate options, and turning your infills into cats. It’s a handy GUI app that should work under Windows, OS X, and Linux, so if you’re running MakerWare right now, you can get up and running with this easily.

One thing [Rich] has been using his new software for is experimenting with alternative filaments. With his Makerbot, he’s able to print in nylon, the wood and stone PLAs, flex PLA, and PET. That’s a lot more material than what the Makerbot natively supports, so we have to give [Rich] some credit for that.

Students build a 3D printed plane

3d printed plane

A student team has successfully designed, built, and flown a 3D printed RC plane using only $16 of plastic with a consumer-grade 3D printer (Makerbot), plus the necessary electronics and motor.

The folks over at the Wright Brothers Institute (WBI) have a great program called the AFRL Discovery Lab which brings teams of students, businesses, researchers, and government together to work on a specific challenge or opportunity.

One of the programs this year was the Disposable Miniature Air Vehicle, or DMAV for short. The student interns [Nathan, Ben, and Brian] spent the first 5 weeks at Tec^Edge designing the plane. The team went through 5 revisions before they settled on a design they believed could fly. The final plane weighed 1.5 pounds, and on its first flight… plummeted into the ground. Good thing they printed a second copy! After some more practice [Stephen] got the hang of it and was able to fly and land the plane successfully.

According to the WBI, this is the first functional aircraft that has been fully 3D printed (sans electronics) using FDM technology, and the first low wing 3D printed plane to be flown. Hate to burst their bubble, but 3D printed quadcopters have been around for quite a while!

Test flight video is after the break.

Makerbot shows off 3D scanner

scan

We’ve said our piece over Makerbot and their interpretation of what Open Source means, but the fact remains if you’re sourcing a 3D printer for a high school shop class or a hackerspace, you really can’t do much better than a Makerbot Replicator. Apparently Makerbot is looking to expand their 3D design and fabrication portfolio; they just announced an upcoming 3D scanner at SXSW. It’s called the Makerbot Digitizer, and it takes real, 3D objects and turns them into CAD files.

Since Makerbot and [Bre Pettis] didn’t give out much information about the 3D scanner they’re working on, the best information comes from Techcrunch. The Makerbot Digitizer uses two lasers to scan real objects and turns them into 3D CAD files. The hardware isn’t finalized, and the prototype is made of a few pieces of laser cut plywood. No details are available on how much the Digitizer will cost, when it will be available, or what its resolution is.

Of course 3D scanning of real objects to translate them into CAD files is nothing new for Hackaday readers. We’ve seen our fair share of desktop 3D scanners, including one that was built in a day out of junk. Even the Kickstarter crew has gotten into the action with a few desktop 3D scanners, some of which scan in full color.

Custom 3D printed designs with Makerbot’s Customizer

custom

Although having a 3D printer means you can create custom object of your own design, that doesn’t change the fact that most object printed on Makerbots and RepRaps are copies, or slight derivations, of already existing object. If you need a gear, just go grab an OpenSCAD file for a gear, and a custom smart phone case can be easily made by modifying an already existing one. The problem with this approach, though, is you’ll need to learn OpenSCAD or another 3D design tool. Enter the Makerbot Customizer, a web app that allows you to create custom versions of other people’s work right in your browser.

The idea behind Customizer is simple: someone creates an OpenSCAD file with a few variables like the number of teeth on a gear or the number of turns on a screw. Customizer takes this OpenSCAD file, puts sliders and radio buttons on a web page, and allows you to create custom objects based on user-created templates.

Already we’ve seen a lot of Hackaday readers send in some pretty cool customizable things, like [Bryan]‘s coil form for DIY inductors and [Greg]‘s customizable PVC pipe couplers. If you already know OpenSCAD, it’s easy to create your own objects that are customizable by anyone on the Internet.

Hackaday Links: September 21, 2012

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

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?

Introducing the Makerbot Replicator 2

A few short hours ago at press conference, Makerbot announced the release of their Replicator 2 3D printer.

The original Makerbot Replicator was released earlier this year at CES and regaled by the press as a quantum leap in home manufacturing (a quanta is actually very small, guys) with and option for dual extruders and a rather large build volume. The Replicator 2 takes the same formula and adds a powder coated steel frame, larger build volume (11.2″ x 6.0″ x 6.1″ or 28.5 x 15.3 x 15.5 cm) and a resolution so fine as to approach the realm of uber expensive 3D printers (100 microns or 0.004 inches).

Base price is $2200 USD for the single extruder model with no Makercare service plan. A dual-extruder Replicator 2X is slated to be released after the beginning of next year. This model will also handle ABS filament, although we can’t find anything that says the single-extruder Replicator 2 is only able to use PLA.

Even though the new Replicator 2 is rumored to be closed source, we’d really struggle to come up with a better 3D printer for a high school shop class, college CS and/or engineering department, or even a hackerspace.
