Vector Space Systems is a privately-held commercial company providing satellite deployment for the space exploration industry. Funded in part by capital investiture in June of this year by a $21M Series A funding campaign led by Sequoia Capital, and with participation from Shasta Ventures and Lightspeed, Venture seeks to be a major player in the micro-satellite business. Their successful test launch of a 3D-printed engine injector this week has made a name for the company in both the space and 3D printing industries, paving the way to broader space exploration and use of 3D printing in space.

The key development in this launch test had to do with the entire engine injector being 3D-printed in one piece, as opposed to being previously assembled from multiple parts. The development of the 3D-printed engine injector was made possible through a grant from NASA’s Science, Technology and Mission Directorate (STMD) Flight Opportunities program.

According to Jim Cantrell, CEO and co-Founder of Vector Space Systems, “Our historic launch today is a testament to the hard work of the Vector team, as well as support from NASA and Spaceport Camden. Together, we’re on the fast-track to get to an orbital capability in 2018 and look forward to continuing momentum and unprecedented growth through the course of this year.”

The Daily 3D Detail: 3D scanner water tank

Posted by Taila Rodrigues On August - 3 - 2017

The traditional 3D scanner methods are based on optical devices, laser and cameras.

Researchers have discovered an unusual scanner method, a 3D scanner immersed in water tank. The object is immersed in a water bath by a mechanical arm, in order to obtain a better reconstruction the object needs to be immersed many times, in this way the water and able to penetrate in all the areas of the object, are also submerged from different angles through of which measures the elevation of water.

This method accurately reconstructs even hidden parts of an object that typical 3D laser scanners are not able to capture.

The team based their method on the ancient principle of Archimedes‘ displacement – the volume of displaced fluid is equivalent to the volume of a submerged object.

The team approach is safe and economical, it is a low cost alternative using an innovative method.

The Daily 3D Detail: Have you heard about Metamaterial?

Posted by Taila Rodrigues On July - 28 - 2017

Metamaterials are small four-sided plastic cells, arranged in repetitive patterns that expand when air is pumped inward, fold into themselves, and easily return to their original shape. These properties can reap benefits beyond what is possible with conventional construction methods. Despite what the name implies, the ingenuity of metamaterials is not in their chemical composition, but in the engineering of their design.

With metamaterials one can easily build cubes at varying rigidity, adding unique mechanical functionality to the item being produced.

Have You Heard about Metamaterial?

The example shown here is a mechanism that can fit a curve using a very precise placement called cut cells. The cutting cell is capable of folding in a controlled, multidirectional movement without requiring any assembly.

As 3D printing becomes more common, thinking in 3D design also becomes less and less limited. Designers world-wide have started working with this kind of versatile, adjustable, and self-actuated material.

The Daily 3D Detail: Meet the 3D Printing Nerd…

Posted by Franka Schoening On July - 12 - 2017

YouTube’s 3D Printing Nerd

… and subscribe to his channel while you are at it. Joel uses YouTube videos to discuss and review 3D printers, analyze polymers and generally advocate for the industry. Check out his video about the Kodama Obsidian Prototype or watch him interview fellow 3D printers like Ben Heck or Josef Prusa. Some of his videos are applicable to practical printing, as he fixes his Subaru’s gas cap and prints and reviews his own feetz. But he also enthusiastically responds to fan mail. If you are lucky, he might respond to your question, showcase items you send him, or take your suggestion on videos you would like to see next. And if you are REALLY lucky, he will send you some stickers, as that seems to be the going currency in the 3D Printing Nerd’s universe.

His passion and curiosity make his videos informative and engaging. While nerd used to be an insult, it certainly is rather a certificate of knowledge when it comes to the 3D Printing Nerd.

 

curve ups free-form objects

A team of Austrian computer scientists has advanced the way of creating 3D objects on a 2D printer, calling it CurveUps. By inserting small tiles between stretched layers of latex, this technique allows for free-form objects featuring curves and round shapes. Formerly, similar objects were limited to sharp edges.

Hydrofill Makes Printing the Impossible Happen

Posted by Editor On February - 3 - 2017

Airwolf3D launches a game-changing support material solution

Hydrofill Makes Printing the Impossible Happen

It’s only one month into the year and Hydrofill has already won a spot on the list of Top Ten Innovations of 2017.

A welcome creation by the team at Airwolf3D, Hydrofill fulfill’s the company’s slogan of being able to print the impossible by being the only water-soluable printable support material available to be used alongside all other FDM printing process materials.

Airwolf3D is the brainchild of husband-and-wife-team Erick and Eva Wolf. They formed the company in 2011. It began with Erick’s necessity in crafting a personal 3D printer to resolve his passion of custom-car design. It was only when Wolf sold his first hand-built 3D printer within minutes of posting it on Craiglist that he and Eva realized they may be on to things. With her savvy in business operations, they have produced a world-renown reputation in the industry with a broad open-source attitude. One of the points to their credit is their use of a 3mm filament size. Combined with a .5mm nozzle on their devices, the filament size makes for dazzling print speeds. Located in Costa Mesa currently where they manufacturer both printers and filament materials, they have made plans to expand to Las Vegas to house the amount of business they are handling. No wonder really, given the release of Hydrofill.

Hydrofill is truly water-soluable. They proved it to people at CES this year and, having personally seen an ocarina (downloadable of Thingiverse.com) give up the entire inner core of it’s Hydrofill support material in 45-minutes of a room-temperature-water soak, we can attest to its magical powers. The mystery behind all this magic is due to Airwolf 3D’s collaboration with Miodrag ‘Mickey’ Micic, a professor in chemistry at Cerritos College in Norwalk, CA. Part of a team of other brilliant people, Airwolf3D has been able to provide this wonderful product that is safe to use and does not hurt the environment. Now everyone can print the impossible.

Everyone with a two-head 3D printer, that is. Although the ingredients in Hydrofill are patented and proprietary, Airwolf3D makes Hydrofill in both 3mm and 1.75mm filament sizes. Once all the clean-up of the print is reduced down to a 45-minute bath soak, the design results will be unlimited. Even the craziest of prints will not be a challenge ever again over whether it can even be done.

Markforged Goes Metal

Markforged announced at CES their breakthrough technology in desktop metal 3D printers

You want stainless steel in a per item basis? You got it. You can also have it in titanium or even more exotic metals. At a price that will change how you think about manufacturing.

Markforged revealed their newest creation the Metal X, which is an ingenious solution to desktop metal 3D printing. By creating filament spools of metals wrapped in plastic, Markforged has devised a 3D printer that is able to FDM print objects which, upon release of the lining in post processing, creates fully metal objects. Not just any metal, mind you. Hard, shiny, rustproof metals.

How the world is changing

One of the key faculties of additive manufacturing is in new material creation. Not only are we able to 3D print objects that could have never before be created, we are also fusing new materials in the processes of 3D layer-by-layer sinterings. Markforged’s team of material experts have been working in this direction with considerable results. Check out the video and visit the Markforged web site to find out more about how affordable it has become to print metal on a small business budget.

3D-Printed Weapons in the News Again

Military.com has reported on U.S. Marines now using 3D printing to produce bullets

The Military.com has announced new developments in the use of 3D printing to produce bullets. According to the report, the U.S. Marine Corps was successful in conducting field experiments in the process of creating on-the-spot munitions for individual missions.

“One of the benefits of being able to precisely control the way that a munition or warhead is ‘grown’ through [additive manufacturing] is that we think we’ll be able to tailor the blast and associated fragmentation to achieve specific effects for particular targets, heights, collateral damage, or even environmental considerations,” said Capt. Chris Wood, the co-lead for 3-D printing for Deputy Commandant of Installations. “Some of this can be done currently with very expensive, hand-made munitions, but [additive manufacturing] allows us to do it better, faster, and likely cheaper.”

The article by Military.com goes on to explain the varieties of ways 3D printing will be providing cost savings and better preparedness for the defense departments in the years to come.

New 3D-printed gun design uses office supplies to function

Also making the news are the reports of a new 3d-printed gun design called “Songbird.” The gun was exposed on Youtube featuring its new design approach, which allows for durability to withstand multiple rounds. The gun is a single shot pistol with a front loading barrel and printed in nylon and ABS. The office supplies include rubber bands and a roofing nail for a hammer pin.

3D gun docs are not free speech

In September of this year, Cory Wilson, creator of the first 3d-printed gun, lost a 5th Circuit appellate court ruling against the U.S. State Department regarding the rights to distribute 3D-printed gun designs under the protections of the 1st Amendment regarding free speech. Wilson originally took his case public when the State Department ordered Wilson, a licensed gunsmith, to cease public access to the files of his gun, the “Liberator.”

The fallout of the ruling has to do with the implications of file ownership being neither protected by constitutional rights of either the 1st or 2nd Amendment.

Severe penalties exist for owners of 3D gun docs

Following the capture of Yoshitomo Imura in Japan, Australia went to great lengths to penalize the ownership of digital plans for the manufacture of 3D-printed guns. In November of last year, they passed legislation to enforce a 14-year incarceration for anyone even possessing such plans on computer devices outside of Australian territory. In Imura’s case, he is serving a two-year sentence in Japan for the possession of five 3D-printed guns he had created through the help of university laboratory printers. What had become noteworthy in the exposure of Imura’s work was the design of 3D-printed revolvers able of firing more than one round without reloading.

Specific wording on the legislation can be found at: http://www.legislation.nsw.gov.au/bills/5bb4f02b-1f1e-48b2-aa93-955574e699f6.

Designers, many of which find solidarity in the FOSSCAD community, have taken Imura’s work and credited him with the success. A later version of what Imura called the “Zig-Zag” gun was introduced and called the “Imura” revolver. Later revolver adaptations have appeared on Youtube since then, with unique design innovations including the placement of the revolver drum at the fore of the weapon, as in James R. Patrick’s “PM522 Washbear.” Alternative approaches to pistol design have included creating an open-chamber ejection method as in Michael Crowley’s “.314 Atlas.”

TSA seizes loaded 3D-printed revolver

While state and federal penalties exist for the ownership of unregistered weapons, the main penalties existing for 3D-printed guns are being enforced by the Undetectable Firearms Modernization Act, whereas weapons must contain a certain amount of metal to be able to be read by magnetic security scanners. Even without this protection written into law, the bullets used in these weapons give themselves away. A loaded 3D-printed revolver was seized by the TSA in August of this year thanks to the bullets in it. While authorities said that a firing pin was missing from the confiscated weapon, photos of the captured firearm appear to indicate the walls of the cartridge drum are too thin to handle the ballistic stresses, and the TSA records the find as a replica.

Fears of 3D-printed guns trafficking in society do exist among the populace due in some small part to exposure in popular entertainment. A trailer for a recent video game launch featured a 3D-printed gun in the game’s trailer, and some of the TV shows on major channels have used the existence of 3D-printed gun as a plot device, but these examples do little for informing the public on the engineering challenges that exist for creating 3D-printed weapons. Also, the rarity of 3D-printed firearms in relationship to the number of legally manufactured weapons in public should always be kept in mind during debates on the right to weapon ownership in general. A recent study, the most exhaustive to date, estimates the number of guns in the U.S. to be 2,650,000, or one weapon per adult. Actual ownership indicates that nearly half of these weapons are owned by 3 percent of the population.

The Autonomous Farting Octopus Robot

Posted by Editor On August - 28 - 2016

Studies conducted at Harvard John A. Paulson School of Engineering and Applied Sciences 3D-printed a soft robot operating through microfluid technology

Here Come the Soft Robots

Jennifer A. Lewis, the Hansjorg Wyss Professor of Biologically Inspired Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences, commented on the project led by Robert Wood, the Charles River Professor of Engineering and Applied Sciences: “Through our hybrid assembly approach, we were able to 3D print each of the functional components required within the soft robot body, including the fuel storage, power, and actuation, in a rapid manner. The ‘octobot’ is a simple embodiment designed to demonstrate our integrated design and additive fabrication strategy for embedding autonomous functionality.”

The octobot’s farting, or gas emission, is a result of the microfluid technology involving hydrogen peroxide that went into the robot’s design to operate its limbs. Scientists are most excited however in embodying chip operation without requiring rigid circuitry.
