Pebble Watch Leading the Way for DIY Economy

This interesting piece by 3d printing.com.  Like the internet in the early days 3D printing has been relegated to geeks and DIY enthusiasts with limited usage. But as the industry has matured it has slowly infiltrated the mainstream.  The story of Pebble watch shows how far 3D printing has come and the potential of where we can go.  How many other Startups and small businesses will spawn from the blades and lasers of a 3D printer?

p2When we decided to launch 3DPrint.com just over 13 months ago, we looked at it as a hobby, but the pace at which things have progressed, both for us and for the industry in general, has taken even us by surprise. Additive manufacturing is changing the world as we know it, and although there are still plenty of skeptics out there, I now truly believe that we are in the midst of the third industrial revolution.

“Why would anyone want a 3D printer? Who wants to pay $1000 to $2000 to be able to print out plastic little trinkets?”

Those are common questions I receive on a weekly basis from family and friends who don’t regularly read our site. The fact is, however, that they are asking legitimate questions. Why would someone pay so much money for a machine to print out plastic trinkets? What these doubters fail to realize when asking these questions is that plastic trinkets are not the driving force of this technology, and prices are rapidly declining. What is driving adoption rates of 3D printers within homes and offices are useful applications which put complete control in the consumer’s hands. As each month passes literally dozens on new applicable uses for desktop 3D printers emerge from companies small and large.

Take for instance what one Palo Alto, California-based company, Pebble, is doing with their smartwatch. Pebble exploded onto the scene during the Spring of 2012. They raised a staggering$10,266,845 via Kickstarter for their E-Paper smartwatch. Soon after, buzz began to emerge that Apple would be launching their very own smartwatch as well, which they later unveiled. How does a tiny startup with several million crowdfunded dollars compete with the most valuable company on the planet? Most don’t. Even I, myself, envisioned Pebble folding soon after the announcement of the Apple Watch. I was wrong, like I am quite often, and instead of rolling over to die, the company did the same thing which initially brought them success: think outside the box.

Last month Pebble launched another Kickstarter campaign, this time for the Pebble Time smartwatch. With weeks still remaining, this campaign has already brought in well over $15.5 million. So, who’s buying a Pebble, and why are they buying it when Apple’s smartwatch is ready to be released within weeks? People who desire the ability to personalize their own accessories.

Pebble has decided that in order to succeed in a market with Apple they must differentiate themselves. How are they doing this? Via 3D printing. Late last month we did a story on Pebble, which had announced that they will be offering free downloadable 3D printing files to whomever wishes to print out their own custom watch bands. Yesterday the company released mechanical and electrical designs so that hobbyists and designers can begin customizing their very own 3D printable smartstraps. In doing so, Pebble is attracting individuals to their brand who want to be a part of their watch design, people who take pride in the fact that they are different, and that they made an impact on the watch that they are wearing.

Now envision a time in the not-too-distant future when almost anything you buy will be able to be customized for no more than the cost of some plastic filament. Now do you see where desktop 3D printers may fit into our lives?

With reliable 3D printers already on the market for less than you’d pay for an average smartphone, such a future seems like it may be closer than even I had imagined. As printers continue to expand in their capabilities, prices drop further, and the sheer number of applicable uses for these machines grows exponentially, there is little doubt in my mind that 3D printing will eventually rule our global economy. The question won’t be “Why would anyone want a 3D printer?” it will be “Why wouldn’t anyone want a 3D printer?” Pebble’s adoption of the technology into its ecosystem is only the beginning.

Let’s hear your thoughts on Pebble and its possible implications on the 3D printing space. Discuss in the 3D Printing Economy forum thread on 3DPB.com.

3D Printing Organs: Tracheal Cartilage and Kidneys.

This video explains the major shortage our society has with the availability of organs, in the last 10 years the number of patients that require organs has doubled, while at the same time the actual number of transplants has barely gone up, creating a public health crisis. This video discusses the field of regenerative medicine and how it plans to solve this problem.  There are specific materials doctors can implant into the body such as stem cells that can regenerate or… actually 3D printing the organs.

One method described here is a patient presented with a diseased organ, the organs are then printed out of special materials based on this organ.

The biggest challenge described in the video is creating whole solid organs in their entirety such as a kidneys. The strategy is to take an xray, and to use 3D reconstruction and 3D imaging to view the patients kidney. The researchers then take this information and scan it into a 3D printer.  Developing more precise 3D printing technology is critical, to furthering this field.

Above is an example of Maker Bot 3D printers being used to create tracheal cartilage

Researchers at the Feinstein Institute for Medical Research have successfully created cartilage using a MakerBot 3D printer. The team made use of the technology to quickly and affordably prototype and refine the bioprosthesis, and even used it to create a low-cost bioreactor to facilitate the growth of the cells.

CNC Simple G-Code Generator

Found some interesting software today they have a great wordpress blog that has an interesting tutorial for generating G-Code using it.

https://cncsimple.wordpress.com/

You can download the software here

Overview CncSimple 2.0

Cncsimple 2.0 is a software for easy generation of G-Code.

Briefly, I show you an example of use.

If we want to create an external turning  we selected the work from toolbar.

Overview_AddWork

Next the operation is added to the treeview below, when the treeview item is selected , in the space below you can insert the parameter.

WORK_SELECTION

Now we want to define the turning profile .
We have 2 choice , one for the simpler profile , and one for the complex profile.

For the simpler i can select [Diameter List] and inputing the diameter and the depth.
DiameterDefineProfile

With more complex profile you can select [Profile Editor] , then click on [Open Profile Editor ]

profileEditor

overview_2

At this point theoretically we can alredy create the G-Code but we want to check the cutting parameter.

Once the profile is defined ,  we want to add rest material to remove with finish tool.

Next we move to next tab to check the generated operation.

If we have setted the rest material now we have 2 operation , roughing and finish ,otherwise we have only roughing operation.

When we selected an operation from the treeview we can alredy see the toolpath on the screen.  The tool parameter are alredy stored in a database , of course  we can update them.

operation

In the next tab we can see the operation grouped by the used tool.

This view make sense when you use the same tool for multiple operation and you want to change the cutting data only once for all operation.

If we want to change the stock material we can change the material from field showed below .  All the parameter will be update to the new material.toolList

Finally we can see the back plotting of toolpath .

Selected the operation you want to simulate, next select the tab [Simulation] from the Menu and press Start.

Toolpath BackPlotting

Now for the machine time summary press the [Analyze Machining Time] on the toolbar.

menuGenerate

timeAnalysis

And to obtain the code press [Generate Code] button.

Defense Distributed 3D Prints a Gun in Front of Capital Building in Texas: or Who Needs a Gun that Big?

Drawing from the very constitution itself activists are calling for a right to bear arms. When Jefferson and Franklin were talking about this they didn’t have Uzis AR-15s or even AKs they had crappy black powder guns that today a kid could buy without a license. What gun laws are talking about today is taking away these weapons of mass killings and mass murder.  In other news some guys print a gun in a form of protest  the Texas State Capitol in Austin yesterday set on pushing lawmakers to ease up on open-carry gun laws, and the main attraction was a 3D printing CNC machine, the Ghost Gunner.  With this device the activists proceeded to ‘3D print’ a gun right in front of the Capitol building.

photo by come and take it texasThe gathering was organized by Come And Take It Texas, or CATI, and the group says it’s “been the front line for gun rights since their inception two years ago.” The bill was filed by state Rep. Jonathan Stickland, R-Bedford, and he says BH 195 is aimed at eliminating the state’s handgun licensing requirements.

tumblr_inline_nf1oyfC7CQ1rwpoc4Though you can legally buy all sorts of guns in Texas often without a license in unregulated gun shows, Texas is one of only six US states where citizens are not allowed to openly carry handguns.

The rally, held in support of a bill filed by state Rep. Jonathan Stickland, R-Bedford, is part of a push to scrap the state’s handgun licensing requirements during the upcoming legislative session. Stickland did not immediately return a request for comment.AThe Ghost Gunner, it’s made by Defense Distributed, famous crowdfunded company first to enter the 3D weaponry printing arena. 

DD’s first project was printing the Liberator as part of its crowdfunding effort, and the desktop CNC Ghost Gunner is the next generation for DD.

“Anybody can purchase one of these to print firearms in their own homes,” Murdoch Pizgatti, president of CATI, told NBC News.

kids-with-guns

Pizgatti said that Come and Take It intended to start a public conversation about laws limiting the use of tools like the Ghost Gunner and the 3-D printing of firearms.

“This is the frontline,” he said. “The 3-D printing … [is] going to be cheaper, more accessible to the average person so people with less technical skills will be able to start doing this for themselves.”

He rejected any suggestion that manufacturing firearms at the Capitol rally might hurt overall support for gun rights.

“Obviously it’s not confrontational, it’s just drilling a couple holes in a piece of metal,” he said. “We heard the same thing when we started open carrying our rifles … and here we are two years later with the open carry laws sponsored, ready to go to the House and Senate and a new governor that has told the media he would sign an open carry law as soon as it reaches his desk.”

The Ghost Gunner uses an aluminum block that’s referred to as “80 percent lower” – a piece which can be purchased for less than $100 – as you can see in the video below you can purchase this piece without a license from any gun store and it is the only piece you need to purchase to make your automatic, you can then begin to mill your receiver in around 15 minutes. Defense Distributed calls the Ghost Gunner project “a non-profit, open source hardware effort.” They add that the Ghost Gunner schematics and design files will be published into the public domain. Based on “crypto-anarchic” principles, this has nothing to do with bitcoin this has nothing to do with crypto this has to do with 3D printing and it has to do without people who feel they need large guns. Do what you want just keep them at home in your closet. There is absolutely 0 reason any one should have one of these on the streets, it should be grounds for life in prison. While they are at it they can free all the nonviolent drug offenders to make space, as drugs will be easier to get then ordering a movie off of Netflix soon.

The device uses 3D printable jigs to hold the receiver part in place as CNC milling steps are completed. When milling an 80% AR-15 lower receiver, the company says two jig pieces are required to secure the lower in place as the ‘trigger pocket’ is milled, and two more jig pieces are used to drill the trigger pin holes.

Defense Distributed says that, in general, using their device to manufacture semi-automatic firearms like the AR-15 lower receivers is legal for private individuals. They add that some states and municipalities restrict either the manufacture of certain firearms, or more recently, the personal manufacture of a firearm with a 3D printer or CNC machine.

As for federal laws, they prohibit the manufacture of firearms for future sale without a Federal Firearms License. According to the ATF, allowing others the use personal CNC equipment may constitute manufacturing, so Defense Distributed tells Ghost Gunner owners to avoid printing firearms for other individuals.
