This Open-Source Robot Can Crack A Safe in 30 Minutes

This Open-Source Robot Can Crack A Safe in 30 Minutes
By Matthew Mensley

Def Con safe cracker

Using cheap open-source hardware, 3D printed parts and some engineering know how, a group of hobbyist hackers have brute-forced their way into a safe, live on stage at the DEF CON cybersecurity conference.

For Nathan Seidle, Bob Reynolds and Joel Bartlett, nuts and bolts are their daily business. Together, they all work at SparkFun, a Colorado, US, based hardware store serving the needs of open-source builders.

By night (figuratively) however, they hack. But cast aside any visions of darkened rooms and lone figures hunched over a computer, furiously tapping lines of code into a keyboard. These hackers are of the hardware variety, focusing on finding and exploiting vulnerabilities in everyday objects that ought not have them.

Entirely for the fun of it, rather than desire for financial gain, the group recently turned their attention to a cheap and fairly common SentrySafe safe.

The group built a machine from parts costing approximately $200. This machine is designed to brute-force it’s way into the safe. Despite the aggressive sound of it,  this simply means that the robot will attempt every plausible combination to unlock the safe.

This safe-cracking robot is the subject of a lengthy piece on Wired. The magazine picked the story up just before the group took to the DEF CON cybersecurity conference.  There, live on stage, they put it to the test in front of a large crowd.

Building a Safe-Cracking Robot

Seidle and co’s break-in bot is comprised of an aluminum frame, Arduino, motor, magnets, sensors and a 3D printed coupler. Thanks to the flexibility of 3D printing, this last part is customizable to fit any safe that uses a rotating dial combination lock.

The way the robot goes about its task is very simple. Attaching it to the front of the safe with magnets engages the ‘bot to the dial.

It then follows a routine to try every possible combination of the three number code. Each number could be as high as 100, meaning from the outset the robot needs to attempt 1,000,000 (100 x 100 x 100) combinations.

To simplify its job however, Seidle and his hacking compatriots have divined some vulnerabilities in the safe that allows them to drastically reduce this number of possibilities.

From the get-go, the robot can determine the final number in the sequence by measuring notches inside the mechanism. A difference of a mere fraction of an inch — undetectable by human hand — is easily found by the machine, which betrays the final number in the combination.

Add to this the discovery that adjacent numbers to the correct code work. This means that the robot tries every third number in its search. In all, through its own actions and the group’s knowledge, the number of possible combinations drop to approximately 1,000.

A far more achievable task. And one that the group’s robot managed to do onstage at DEF CON in approximately 30 minutes.

Is My Safe Safe?

Seidle gives the assurance that this doesn’t herald the dawn of machine-enabled kleptomania. Speaking to Wired, he said: “You’re going to have an army of geeks like myself poking and prodding and trying to do things like this… . The nature of the toolset is getting cheaper, so more nerds are getting brave with their puzzling.”

SentrySafe said in a statement regarding the matter:

“In this case, there was a tremendous effort, uninterrupted time in a controlled environment, the right tools and significant technical knowledge needed to eventually manipulate the safe… . In this environment, the product accomplished what it was designed to do and would be realistically very difficult, if not impossible, for the average person to replicate in the field.”

It’s easy to draw the conclusion of this being a safe-cracking machine for anyone to build and get-a-robbin’. But it’s probably not the best method for breaking open such safes. Seidle adds, “There are so many cheaper and better ways to open up a safe than building one of these.”

US Navy 3D Prints First Submersible Hull in Just Four Weeks

US Navy 3D Prints First Submersible Hull in Just Four Weeks
By Bulent Yusuf

US Navy

The US Navy has 3D printed their first submersible hull, developed by the US Departments of Energy and Defense with support from academia and industry.

Don’t Miss: World’s 33 Biggest & Most Expensive Large Format 3D Printers

Is that ceremonial bottle of champagne ready for smashing? The US Navy has 3D printed the hull of a submersible vehicle, their largest object yet made using additive manufacturing technologies. The proof of concept is made from 6 carbon-fiber composite sections, and was constructed in just four weeks.

The Optionally Manned Technology Demonstrator is based on the submersible SEAL Delivery Vehicle (SDV). SDVs are typically used to transport US Navy SEALs and their equipment on special operations missions. The use case is that such vehicles could be manufactured faster and incorporate new designs for custom support on each Navy mission.

The hull is the result of a collaboration between Oak Ridge National Laboratory’s Manufacturing Demonstration Facility (ORNL MDF) in Tennesse, United States and the US Navy’s Disruptive Technology Lab.

See it in action in the video below, released by the US Department of Energy:

US Navy Plumbing New Depths with 3D Printing

The team at the ORNL was asked to build a 30-ft proof-of-concept hull out of carbon fiber composite material. Given only four weeks to complete the job, they used ORNL MDF’s Big Area Additive Manufacturing (BAAM) machine. This is an industrial 3D printer that lays down a thermoplastic resin reinforced with chopped carbon fibers.

The most remarkable result from this project is not just the size, but the savings in cost and time. The price of a conventional SDV hull hovers in the region of $600,000-$800,000 dollars. Moreover, they’re typically manufactured in 3-5 months. Using BAAM reduced hull production costs by an astonishing 90%, and reduced production time to a matter of weeks.

For the next phase of the project, the US Navy wants to create a second, water-tight version of the hull. The new hull will be tested in the wave pool at the NAVSEA Carderock Division in Maryland, United States. This is a facility that replicates the most challenging conditions that ships and submarines might encounter in the open sea.

If the waters for research and development are not too choppy, fleet-capable prototypes could be introduced as early as 2019.

Danit Peleg Launches 3D Printed Jacket Costing $1,500

Danit Peleg Launches 3D Printed Jacket Costing $1,500
By Hanna Watkin

danit peleg

Danit Peleg is back with a second collection of 3D printed clothing; the centrepiece is a limited edition jacket, an absolute snip at $1,500.

Could it be that the revolution in 3D printed fashion is finally happening? A customizable 3D printed jacket has just hit the market, and it’s an absolute bargain for only $1,500…

Danit Peleg is a fashion designer from Tel-Aviv, Israel. Instead of using conventional fabrics, she deploys a 3D printer to create stunning designs.

You may remember Peleg as the creator of the 3D printed dress Amy Purdy wore at the Paralympics in September 2016. She’s been busy since then, with a 3D printed collection that has graced catwalks worldwide. Her latest work is a second 3D printed collection inspired by Botticelli’s painting, the Birth of Venus.

The centrepiece of the collection is a limited edition 3D printed jacket, which is pitched as the first 3D printed garment for sale online. Because this jacket takes 100 hours to make and print, Peleg is only releasing a limited number of 100.

Surprisingly, the 3D printed jacket doesn’t need to be a futuristic tech show piece; it also looks great paired with a simple pair of jeans. Check out the jacket and other ready-to-wear options in the video below:

Danit Peleg Stakes Unique Place in Fashion World

If you have $1,500 to spend on what could be a unique item in the history of fashion, you can head to the customizer on Peleg’s website. Here, you can choose your jacket’s color, lining and even wording for the back.

The $1,500 pays for the time it takes to make and material costs. And even if you don’t have one a half thousand bucks to drop on a limited edition jacket, you can still enjoy playing with the customizer.

To make these jackets, Peleg is collaborating with AccuMark 3D and YuniquePLM. In order to create a comfortable and functional jacket, she uses a rubbery, flexible material and then lines the design with fabric.

Peleg explains: “My vision of the future is that you will buy your 3D print file and print your clothes at home or at a designated store.” You can visit Peleg’s store here to buy your own jacket or check out her other designs.

Revolutionizing Facial Reconstructive Surgery with 3D Printing

Revolutionizing Facial Reconstructive Surgery with 3D Printing
By Hanna Watkin

3d printing plastic surgery

3D printing brings major improvements to facial reconstructive surgery, helping to better recreate a patient’s face after serious trauma.

Doctor Laurent Lantieri is a facial reconstructive surgeon working at Georges Pompidou Hospital in Paris, treating only patients with the most serious of injuries. His work revolves around making his patients look as close to their original selves as possible. In 2010, he led the world’s first full face transplant.

More recently, Lantieri has been working with Materialise to produce implants which are identical to a patient’s original facial bones. First, Lantieri 3D scans a patient’s face using a 3D CAT scanner. Next, clinical engineers at Materialise use the scan to create a 3D model and then 3D print the implants to replace the damaged bone.

Prior to 3D scanning and 3D printing, this was an extremely laborious task. Lantieri would spend hours searching for the right implant for patients. “Before we were just guessing, trying to do it with the CT scan and using standard material,” he explains. “It was complicated, we never had the correct, perfect shape.”

Today, this long process is transformed into one which provides titanium plates and patient-specific implants which are a superior match.

3D Printing for Facial Reconstructive Surgergy with Concept Laser Printers

A major benefit of using additive manufacturing is that no matter what shape Lantieri needs to work with, it’s possible to print. Even the most spiky edges are possible to create using industrial 3D printing machines from Concept Laser.

After the design process ends, Lantieri measures and approves a prototype before final printing. He says:

“In the past, I was just guessing… We never had the correct shape. But using 3D printed skulls — to have them in my own hands — to determine what are the difficulties, where are the impediments in advance, it makes a huge difference.”

Although the planning process is a lot more time-consuming than previously, it has major benefits such as speeding up facial reconstructive surgery. As well as this, Lantieri is completely prepared when he walks into the operating room with the titanium implants, no matter how complicated the part.

After printing, it’s possible to quickly match the parts with screws which come in specialized kits, Lantieri adds:

“The OR nurses love them… They just have to open the box and we have all the different elements in order of use. No more boxes. We save time because we know exactly what we have and where it goes. Everything is exactly what I want and what I need for each step.”

By Hanna Watkin

Cascade Lacrosse

Cascade Lacrosse uses Lulzbot 3D printers to test new ideas and bring comfortable, safe helmets to the market in a shorter amount of time. 

Don’t Miss: LulzBot Mini Review: This Mighty 3D Printer Does the Job

The sport of Lacrosse is rapidly growing in popularity in the United States. For sportswear manufacturers, staying ahead of the competition and providing the best equipment is a challenging task.

Cascade Lacrosse is a company which is using modern technologies to improve lacrosse helmets and equipment. The company is using LulzBot 3D printers to generate ideas quickly and cost-effectively.

So far, the technology is greatly benefiting the design process. This is shown in the introduction of a new range of women’s lacrosse equipment called Cascade LX. There are many innovative aspects to the new designs, such as an integrated goggle system which relieves the facial pressure of wearing separate goggles.

The company hopes to use 3D printing to further explore and improve this category. By using 3D printing, they can create reliable prototypes and ultimately produce high-quality products.

Chris Laurita, product developer at Cascade Lacrosse, explains the process of choosing a 3D printer. “The ability to print flexible material using its Flexystruder Tool Head,” he says, “made choosing the LulzBot TAZ 3D Printer an easy decision for us.”

Cascade Lacrosse is a Industry Leader

The company uses two LulzBot TAZ 3D Printers and prints with NinjaTek filaments. Laurita continues:

“Any part on our helmet that is flexed or needs some squish to it gets printed on one of our LulzBot TAZ 3D Printers with a Flexystruder Tool Head.”

Amazingly, the company points out that their 3D printers have been in use almost continuously for the last year. By doing this, they’re able to push ideas further and develop prototypes while saving money.

Laurita has nothing but praise for the technology. He adds:

“Payback-wise, printing functional flexible parts on our LulzBot TAZ 3D Printers has given us the confidence to skip prototype tooling on multiple occasions; this saves us thousands in tooling costs and months on our timelines… Design-wise, we cannot put a price on being able to test out concepts that we would need tooling for in the past.”

After great success with 3D printing and the new Cascade LX range, the company is now collaborating with sister companies Easton Baseball, BAUER Hockey, and Maverik Lacrosse. The Cascade Lacrosse team is sharing their knowledge and benefiting the entire organization.

The company strives to redefine headwear and create safe, comfortable designs for players. If you would like your own Cascade Lacrosse helmet, be sure to visit their website.

SparkMaker Introduces $249 Desktop SLA Printer on Kickstarter

SparkMaker Introduces $249 Desktop SLA Printer on Kickstarter
By Tyler Koslow

SparkMaker is introducing their new product, the SparkMaker desktop SLA 3D printer, for a shockingly low retail price of $249. 

When it comes to the desktop 3D printing market, most machines are confined to FDM technology. However, the number of consumer-grade stereolithography (SLA) printers continues to rise.

Previously, this niche sector was completely dominated by Formlabs and their Form 2 desktop printer. But just as cheaper FDM models have recently flooded the market, so have affordable desktop SLA 3D printers.

Don’t Miss: Formlabs Form 2 Review: The SLA 3D Printer Benchmark

The latest SLA printer to capture our attention is the SparkMaker, an extremely affordable desktop machine that recently launched on Kickstarter. With a low retail price point of just $249, this compact printer could spark a shift towards more affordable SLA 3D printing.

SparkMaker SLA 3D Printer: Specs and Features

According to the Kickstarter campaign, the SparkMaker will offer 100 micrometer XY resolution and up to 20 micrometer Z layer thickness. The printer is also equipped with a print volume of 102 x 56 x 125 mm.

On top of that, the SparkMaker team is boasting an incredibly simple three-step printing process. With an SD card, the user will simply upload their desired 3D model, fill the printer with resin and press the giant button on the front of the printer.

This single-button design certainly seems inspired by the Form 2, widely recognized as the benchmark desktop SLA printer. In fact, one could say that this printer looks like a cheaper offspring of the Formlabs flagship product. Nonetheless, the advertised price of $249 is a bargain if the SparkMaker can deliver.

The company will also offer five different types of resin, as well as five color pastes to provide a more colorful printing experience.

Kickstarter Success Story Or Another Crowdfunding Let Down?

As most of us know, the 3D printing community has been let down by crowdfunding campaigns in the past, be it an inefficient product or straight up scam. We’ve covered a few Kickstarter dilemmas in the past for SLA printers, including the ongoing ONO smartphone printer saga and the infamous Peachy Printer debacle.

So, how do we know whether the SparkMaker will be the real deal or not? Well, the truth is, it’s impossible to say with almost any crowdfunding campaign. However, a little investigative browsing can go a long way for those trying to decipher fact from fiction.

On the Kickstarter page, the SparkMaker team showcases a wide range of blueprint plans, and even a video of the printer in action.

Impressively, the company is aiming to deliver the product to early backers by December 2017. While we always urge our readers to invest with caution, this SLA machine is definitely worth a look-see for those on the hunt for affordable desktop SLA printing.

The Kickstarter campaign has already gained a ton of traction. At the time this article was written, the SparkMaker raised $147,760 from 758 backers, and it still has 44 days to go. The team originally offered an early bird price of $99, but that special offer has since been filled. Still, potential backers can obtain a SparkMaker printer and 100g of resin by pledging $159. Otherwise, the printer is expected to retail at $249.

Could the SparkMaker be the next big thing in desktop 3D printing? Check out the campaign here and let us know what you think!

Snow Business: 3D Printing Fake Snow Nozzles using Ultimaker

Snow Business: 3D Printing Fake Snow Nozzles using Ultimaker
By Hanna Watkin

A world leader in supplying fake snow, Snow Business use Ultimaker 3D printers to save cost and time in prototyping and testing final parts.

Don’t Miss: Ultimaker 3 Review: Revolutionary Dual Extrusion 3D Printer

Have you ever wondered who supplies the snow for movies which weren’t filmed during winter months? For example, titles like Spectre, Kingsmen, or Bridget Jones’s Diary?

The answer is Snow Business. The company supplies fairs, productions and live events with snow machines which help set the perfect ambience. What Christmas fair would be complete without some festive fake snow?

However, making a snow machine’s complicated final design requires a lot of iteration. To make things better, the company is using an Ultimaker 3D printer.

By doing this, they can prototype, test and even create final parts for the machines. A major benefit of the technology, of course, is that the company can speed up their iterative design process and save money by having a 3D printer in-house.

The company began by outsourcing parts; however, they found this took too much time. Paul Denney, Head of Research at Snow Business, explains:

“What I really needed was a technology that I could use myself, on-site, that would be able to do what I needed it to do. That’s when we bought our first Ultimaker.”

That’s Snow Business: 3D Printing the Perfect Fake Snow Nozzle

Thanks to 3D printing, creating the machine’s nozzle is a much simpler process than before. If you’re wondering, the nozzle is where air mixes with fluid to create a beautiful snowfall effect.

However, the reason they’re so difficult to manufacture is that their shape is extremely complex. In fact, the air and fluid flow geometry makes the part impossible to cast by conventional injection moulding. 3D printing is undeniably the better option but even so, the process requires extensive trial and error.

Additive manufacturing saves the company a lot of money in the long term, even with extensive iterations. Denney estimates the first printer paid for itself within just two weeks of purchase.

The company prints the nozzles in ABS on the Ultimaker 2+. Using this method, Denney would split the model up into two parts. After printing he’d glue them together. By doing this, he would avoid support structure marks on the ABS print.

However, the company is now investing in a second 3D printer — the Ultimaker 3. The benefits of buying this printer are already clear. Denney can save both time and money by printing the nozzles in one piece.

To do this, he now uses Nylon and water-soluble PVA support. As a result, the final prints don’t require any post-printing assembly and have no marks.

Perfected3D is a New Service to Streamline 3D Printing Services

Perfected3D is a New Service to Streamline 3D Printing Services
By Hanna Watkin


Whispering Gibbon is offering a free beta trial use of its Perfected3D software, which converts designs into models for easy 3D printing.

Imagine being able to simply 3D print a model of your favorite video game creation with just the press of a button. Currently, it takes a little more effort than that; the process of turning a design into a 3D print requires time and skill.

Whispering Gibbon is a UK-based tech firm hoping to change that. Their technology could help users create 3D models which they can then quickly and easily print.

The service, called Perfected3D, is now being offered for free to UK-based companies as part of a beta trial. Joining the trial is simple and the beta service is free to use online — companies only need access to a 3D printer and they’re good to go.

The aim of the trial is to show that 3D printing technology can be more accessible and efficient. This is because Perfected3D automates the whole printing process. Joe Stevens is founder and CEO of Whispering Gibbon. He explains:

“Traditionally 3D data has been manipulated to be viewed on screens. It has been created to be viewed and now people are starting to print them, but the object that is viewed is not printable. There might be small holes in the product or it might be too thin. Most 3D models are manually ‘hand-fixed’ to make them print ready, which is costly and time consuming. By fully automating the process our platform keeps costs down and enables scale.”

Whispering GibbonPerfected3D Makes 3D Printing More Accessible?

This year, Creative England invested in Whispering Gibbon to help the company focus on the launch of their software. After a rebrand, and a name change from RenderFab to Perfected3D, the trial is underway.

So far, the technology is proving particularly useful for companies working with architectural models or video games. By using Perfected3D, companies can convert scenes or architectural designs into 3D models which are ready to print.

“This makes 3D printing much more accessible for smaller companies and cost effective for bigger companies,” continues Stevens, “allowing them to create personalised content and easily scale up.”

Lockwood Publishing is a company which is already using the service. You may know them from their online video game Avakin Life. Joel Kemp is director at Lockwood Publishing and he explains:

“This tech allows the users of our app, Avakin Life to turn their unique video game creations into 3D print ready models and we have been really impressed with the results.”

Currently, only those in the UK are able to test the technology. But, don’t worry as after the trial, Whispering Gibbon plans to release the tech to a much larger audience of three million users worldwide. Head to the official website to find out more.

Robot BADGER Can Drill Underground and 3D Print Tunnels

Robot BADGER Can Drill Underground and 3D Print Tunnels
By Bulent Yusuf


Not a hoax, not an imaginary story. The EU is funding an underground robot called BADGER which can drill and 3D print curving tunnels.

The European Union is sponsoring an underground robotics project that can drill underground and 3D print tunnels in its wake.

In full, it’s described as a “robotic system that will be able to drill, maneuver, localize, map and navigate in the underground space, and which will be equipped with tools for constructing horizontal and vertical networks of stable bores and pipelines.”

But the best part is the name. The robot goes by the name BADGER, a selective acronym for roBot for Autonomous nDerGround trenchless opERations, mapping and navigation.

So what are the problems that BADGER is trying to solve? Currently, construction companies already use digging machinery to excavate underground, and install pipes and cables. But this equipment has limitations; it’s not able to detect and navigate around rocks, pipes, roots, and other obstacles on its own. It depends on humans to determine exactly where to dig.

Another problem is that these machines are designed to travel in mostly straight lines. They can’t build a winding network of tunnels. And they’re expensive to operate. It’s actually easier (but massively disruptive) for construction companies to dig a trench, install the pipes into the hole, and then cover it all up again.

By comparison, BADGER will be able to autonomously burrow under the ground to create channels for the pipes, and navigate around existing infrastructure. It’s even able to 3D print walls for the path it creates as it goes.


Is BADGER the Future of Underground Engineering?

BADGER is designed initially for small diameter tunnels, digging conduits for cables and pipes. The initial plan, according to project co-ordinator Carlos Balaguer of Carlos III University (no relation) in Madrid, is for the machine to burrow at depths of up to four metres at speeds of around two metres an hour. If successful, it should be possible to increase in speed and scale.

The “face” of BADGER combines a conventional rotary cutting head with an ultrasonic drill; this will pulverise rock with high-frequency sound waves. Just like existing machines, the spoil will be sent to the surface. Unlike existing machines, however, BADGER will move forward like an undulating worm.

The rear section will clamp itself to the wall of the newly cut tunnel and push the front section forward. The forward section will then clamp itself and pull up the rear. As it progresses, BADGER will line the conduit it has created with a 3D printer. One possibility is to print the wall with plastic, so the finished tunnel functions like a conventional pipe.

BADGER will navigate using various sensors including, crucially, ground-penetrating radar. This will enable it to operate autonomously and detect potential obstacles before it reaches them, so that it can steer around them. The great benefit of BADGER is being able to excavate tunnels below busy cities without closing roads to dig trenches.

The project began in January this year, and is funded for €3.7 million over the next three years. Prototype hardware is not yet available, but with the prospect of loopy 3D printed tunnels beneath our streets, the future looks anything but boring.
