Metal Wars! MarkForged and Desktop Metal Go Head to Head

Posted by Editor On March - 27 - 2018

An explanation of the processes in 3D printing in metal by Desktop Metal, who has sued MarkForged for patent infringement.

With allegations of corporate espionage already bandied about in an ongoing legal battle between the 3D printing industry’s two largest metal printer providers, this metal war bears nothing but gloom for an eager market. MarkForged CEO Greg Mark has issued a statement rebutting the accusations of spying made by Desktop Metal as “far-fetched.” MarkForged also announced a forthcoming countersuit.

The legal battle is over proprietary processes being invented to bring 3D printing in metal to an affordable range as moderately sized machines. The patents in question are U.S. Patent number 9833839 and U.S. Patent number 9815118. The court filing made by Desktop Metal is a preliminary injunction against MarkForged to prevent them from continued infringement of the patents. The request for a jury-based civil trial is also asking for compensation from MarkForged for twice the amount of their damages to the sum of nearly $1 billion.

The main point of contention is due to a sacrificial support layer added in the printing process that facilitates post production. For Desktop Metal, that separation layer is referred to as an “interface layer” while MarkForged uses the term “release layer.”

Both MarkForged and Desktop Metal began limited production roll-out of 3D metal printers late in 2017, with Desktop Metal planning a release of their production studio sintering oven manufacturing suite in 2019.

Enthusiasm for these devices is already frothing the surface of the 3D printer market and the prospect of desktop printing in metal is bringing many new buyers into the fold. Such an economic driver is bound to make people do dramatic things. According to Beau Jackson, a seasoned reporter for 3DPrintingIndustry.com, “With several 3D printing systems seeking to compete in this market it is not unwarranted to speculate that the current legal challenge may be part of an aggressive marketing strategy. Indeed, 3D Printing Industry first heard about the case in mid-2017.”

While such speculations are not without merit, there are factors in the case which beg some investigation. Former Desktop Metal technician Matiu Parangi is the brother of Abraham Parangi, director of technology & creative at MarkForged. The filing of the lawsuit by Desktop Metal alleges Matiu Parangi “downloaded documents unrelated to his work on the print farm, including documents containing Proprietary Information such as a document titled “Engineer Status and Goals -160912.” The matter is further complicated by Desktop Metal’s CEO Ric Fulop being an early investor and board member at Markforged who is quoted as saying, “We believe Markforged products clearly utilize technology patented by Desktop Metal and we will do what is necessary to protect our IP and our company.”

Stay tuned. This metal war could get loud.

The Daily 3D Detail: Advances in Solar Greenhouses

Posted by Editor On November - 5 - 2017

While not yet in the immediate purview of 3D printing, solar technology advances are an item of immense importance to nearly all industries. This story is no exception.

Researchers at the University of California Santa Cruz have published their findings on solar greenhouses wherein plants do well in energy-producing buildings.

According to the report, “Electricity-generating solar greenhouses are outfitted with transparent roof panels embedded with magenta luminescent dye that absorbs light and transfers energy to narrow photovoltaic strips, where electricity is produced. A new study shows that this novel technology, which has the potential to take greenhouses offline, didn’t interfere with plant growth or production.”

The Daily 3D Detail: New Algorithm Speeds Up FDM 3D Printing

Posted by Editor On October - 24 - 2017

University of Michigan’s Smart and Sustainable Automation Research Laboratory (S2A Lab) reports they written a new algorithm capable that can speed up an FDM 3D printer to operate up to ten times the speed.

Researchers 3D-printed a 37.23mm-wide scale-model of the U.S. Capitol Building in three hours and six minutes, achieving an acceleration rate of 10 m/s2.

An ordinary 3D printer accelerated to this point without the new algorithm would result in a failed print because of shifting layers from vibrations of the stepper motors.

Molong Duan and Deokkyun Yoon, researchers of the Michigan study, under the direction of Professor Chinedum Okwudire, said, “The motion of the printer’s build platform is along the x -axis, while its print head moves along the y – and z- axes.

“All three axes of the printer are controlled by stepper motors, but the focus of this study is on controlling its x – and y- axis motions which generate significant vibration, due to the printer’s flexible structure, as its print head and build platform move.”

In an industry raft with acronyms, there’s one more to add to the list: LPFBS (limited-preview filtered B-spline). This is the method devised by Duan, Yoon, and Okwudire addressed by the algorithm. By using an online feedback loop, a realtime check system is conducted that constantly rights the printer head for an accurate position.

The value of the algorithm could be considerable for 3D printing, as it can be easily implemented in spooler software, applicable to all levels of desktop 3D printers, and much less costly than sensors and hardware options.

The report was published in the scientific journal Mechatronics and available at ScienceDirect.com. For more on the story, visit 3DPrintingIndustry.com.

The Daily 3D Detail: New DLP Method Promises Speedy Results

Posted by Editor On October - 19 - 2017

Sprybuild, a company in Ukraine, has offered the world a new look at photopolymer printing. The technology maybe the fastest means of digital light processing discovered yet. Called Continuous Production with Wavefront Converting (CPWC) this new method allows for printing speeds of 10 mm per minute in the z-axis. The development may have an impact in bioprinting, if not directly, than at least indirectly on the quick iteration of optical fibers and stents.

To find out more on this DLP discovery and the method by which CPWC is able to achieve such rapid print times, please see Rawal Ahmed’s story at 3DPrinting.com

Altair’s award presentation and gallery celebrates the nexus of technology + design

By Gregory van Zuyen

Converge 2017 Event Report

Christine Outram of Veritas Prep speaking at Converge 2017 on five trends to watch

We will start with the name of the guy you want to know most. His name is Chad Zamler. Why? Becaue he’s the guy that will give you a pass to Converge 2018. If you are lucky, he may still get you passes to Converge 2017 in other cities.

Converge? What’s that? you ask. Why, it’s the only thing in the world more brain-blowing, more creativeley inspiring, more idea-intoxicating than TED talks on steroids. It all happened here at the Skirball Center in Los Angeles on Sept. 13. If you were anywhere close to Southern California that day, it was the place to be.

Converge 2017 Event Report

The accomplishments and innovations of the people that spoke at Converge is astounding. Through the Converge award program — presented by Altair‘s entertaining CMO Jeff Brennan — we are introduced to the thinkers and artists that give us license to think more imaginatively and more expansively than we thought possible. These are the brilliant and inspired genii of our generation, worthy of world respect.

Converge 2017 awarded nine people for their contributions to the nexus of design and technology. The awards do not go lightly. The value of thought that the award winners provide our planet are so worthy of contribution, the very small 3D-printed statuette they receive is all that more precious a symbol of meaning. How ever much the cinematic world considers the Oscar, that’s how much more the techno-design world will consider the award of the Converge Chair of Accomplishment.

Converge 2017 Event Report

Tim Prestero’s Firefly incubators for third-world countries has saved babies’ lives already

The Converge 2017 presentation began with Tim Prestero of Design That Matters. It’s hard to condense the feels of his talk into a paragrpah, because he dealt with the construction of infant incubators for third-world countries. He went blow-by-blow through the process he had to go to through to design and create a device that would drastically reduce the greatest cause of infant mortality; lack of warmth combined with the common onset of jaundice.

Prestero explained his search for a solution that solved all the issues coming from doctors, nurses, patients, hospital administrators and repair personnel. His years-long odyssey resulted in the Firefly, a portable basinet that provided life-saving UV rays from both above and below the baby. It’s not an exaggeration to say that this man is personnally responsible for the preservation of thousands of lives.

It gets better from there. Christina Outram of Veritas Prep brought unimaginable insight into the future with her analysis of trends to watch; the tracking of recycled electronics, the death of websites through speech-driven apps, customizing the user experience for keener levels of market share, and more. Again, you wish you were there.

When it comes to industrial design, few hold the authority of Tim Morton. The contribution he and Newell Brands have done for Rubbermaid alone earns him a lifetime achievement award. In his talk he introduced concepts like “plaid,” a mixing of the verticals and horizontals of an industry for conceptualizing better product design.

Architect Doris Sung of DOSU Studio Architecture was next, speaking about her development of smart materials for an application to architecture. A professor at University of Southern California, Sung turned an academic investigaton into bimetal composition into a solution into autonomously heating and cooling buildings through the natural process of turning otherwise flat, combined pieces of metal into a curled, ventilating, basketweaved surface by the action of solar heat.

Columbia University Professor of Engineering and Data Science Hod Lipson came on stage next and blew our minds with self-learning robots that seek the rewards of self-duplicating. Like humans, only with robots. He even tore the arm off one of the robots to see how it would adapt. Stunning.

The playlist gets better. Bill Washabaugh is sculptor leading a troupe of phenomenal people at Hypersonic. The NYC-based organization develops industrial installations of themed robotics, the result is a three-dimensional spectacle of awe and wonder.

Converge 2017 Event Report

Breaking Wave by Hypersonic is an example of Bill Washabaugh’s contribution to using technology in design

Greg Lynn of Greg Lynn FORM led us into a journey into the future that cannot be forgotten once seen, especially as it is already here. His design of valet robots trained to follow owners is expected to provide pedestrians greater functionality in populated areas. His vision is epic in scope and magnitude by the virtual simplicity of robots that follow you and carry your stuff for you. This development is soon to be literally at your heels in a short time to come.

Converge 2017 Event Report

Guests examining products made possible through the use of Altair’s numerous enterprise solutions

Michael Peng was next. In architectural circles, Peng is the master. Peng was the force behind Gensler’s construction of the 2,073 ft. Shanghai Tower. One of the many notable features of the tower is that its exterior skin twists 120 degrees around the building to shield it from typhoons. Peng took less than thirty minutes to explain how he did it.

Jason Lopes was the show finale. Lopes works for Carbon and he regaled the audience with stories of his days with Stan Winston and Legacy Effects studios. As their lead systems engineer, Lopes oversaw many notable products, and one of them was the construction of a 14-foot animatronic beast for San Diego’s Comic-Con. Operated by four men inside, this one-of-a-kind creation came to life in a record 30 days thanks to Lopes’ use of 3D-printing. The beast went on to wow the crowds for Jimmy Kimmel Live! show — and wowed us as well.

The event concluded with dinner and entertainment by Nick Waterhouse. For the fortunate creatives that were able to attend this uplifting affair, it will never be forgotten. For those that yearn for the keen gleanings of design’s Mt. Olympus, this is the place to be next year.

The Daily 3D Detail: 3D-printing giant LEGO blocks

Posted by Editor On August - 27 - 2017

3D-printing giant LEGO blocks

As many parents of young children understand, the commodities markets (gold, silver, pork bellies) shamefully neglect to catalog the ongoing rate of one of the world’s most collectible items: LEGO blocks.

As LEGO blocks continue to hold their dollar value over time, the prospect of 3D-printing them grows. LEGO blocks are originally made of ABS (acrylonitrile butadiene styrene) and can be easily duplicated by most 3D printers. STL (stereolithography) files for LEGO block downloads have been around for years.

As the “world’s most powerful brand” LEGO has a strong tradition based on a singly mindful element of their product. It’s virtually impossible to replicate precisely. Even asian knock-off brands of LEGO blocks fail miserably across the board in terms of ease of use and reliability. And forget about having them work together with true LEGOs.

In terms of legal precedent in the LEGO trademark, a number of companies have been sued for infringing upon the LEGO design of their interlocking blocks. LEGO patented their definitive shape of the bricks with their inner tubes in 1958, but the latest European Court of Justice ruling in 2010, stated the eight-peg design of the original Lego brick “merely performs a technical function [and] cannot be registered as a trademark.”

Knock-off companies like Wise Hawk are shameless in their marketing and produce inferior products

So printing one’s own blocks are likely to run into the same quality control issues that plague all other attempts at replicating LEGOs accurately. But printing them at five times the size? That’s a different animal altogether.

Mantis, a two-ton hexapod built by Matt Denton

Meet Matt Denton. Denton’s claim to fame is being the creator of the six-legged two-ton human-scale hexapod called Mantis. His latest contribution to the world is his giant-sized LEGO block creation, a five-times scale model of a LEGO go-cart, model no. 1972. Designed as a LEGO kit in 1985, this buggy cart with dual wheels and working rack-and-pinion steering took 168 hours to make — approximately seven days of printing. The end result weighed 5.1 kilos and cost a little over £100.

In his video series in two parts on the 3D printing of the blocks, Denton explains his tricks of the trade to replicate the LEGO creation in its massive size off a Lulzbot Taz 5 printer. Using extensive brimming to minimize warping at the edges, and foregoing support material in key spots were some of the techniques Denton employed. The video is extensive in construction detail, explaining which parts should be built in sections. No doubt this will not be the first of these mega-size LEGO creations, as anyone with a 3D printer can follow Denton’s lead through his step-by-step instructions.

It’s only a matter of time now until giant LEGO blocks becomes its own sub-Reddit thread. In the meantime, investing in LEGOs still proves to be a viable retirement plan for most parents.

The Daily 3D Detail: 3D-printed robot uses sign language

NewAtlas.com is reporting on the development of Project Aslan (ASL is the acronym for American Sign Language; ASLAN itself is the acronym of “Antwerp’s Sign Language Actuating Node”), a robotic device capable of interpreting spoken language into sign language for the benefit of deaf people.

Created by a team at the University of Antwerp in The Netherlands, in conjunction with 3D Hubs, Project Antwerp at this stage is a robotic hand that is able to sign letters and words spoken to it. Developers are attempting to create a full-body model to use both hands and an expressive face for its translation functions.

3D-printed robot hand uses sign language

This is not the first robot created to address sign language needs in society. Toshiba developed a signing robot in 2014 to help the elderly. Project Aslan is notable as much of the physical components are 3d-printed.

According to the story, the robot hand is made up of 25 plastic parts 3D-printed from an entry-level desktop printer, plus 16 servo motors, three motor controllers, an Arduino Due microcomputer and a few other electronic components. The plastic parts reportedly takes about 139 hours to print, while final assembly of the robot takes another 10.

Guy Fierens, Stijn Huys and Jasper Slaets are the three master’s degree students who began Project Aslan in 2014. Huys commented on the undertaking by saying, “I was talking to friends about the shortage of sign language interpreters in Belgium, especially in Flanders for the Flemish sign language. We wanted to do something about it. I also wanted to work on robotics for my masters, so we combined the two.”

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.
