Week in Review: September 19th to 26th – AM Materials’ Expansion

Hello, welcome to another week in review brought to you by Authentise.

This week got a lot of buzz going for breakthroughs and materials bringing excitement to the world of AM: we got 3D printed cemented carbide tools courtesy of Fraunhofer Institute for Ceramic Technologies’ (IKTS) new binderjetting technique, bioengineered plastic spitting bacteria to supply future space missions and a whopping AM breakthrough in flexible thermoelectric devices which promises plummeting prices for coming IoT clothing and more.

Let us begin.

 

Fraunhofer IKTS develops 3D printed carbide tools with adjustable mechanical properties

Fraunhofer IKTS will present 3D printed cemented carbide (hard metal) tools at the World PM2016 Congress & Exhibition… IKTS scientists used a binder jetting 3D printing method to produce the tools. According to the researchers, these 3D printed tools are of comparable quality to those produced using conventional methods, and can be made into more complex shapes.

Week in Review: September 12th to 18th – IMTS and 3Diax

Hi everyone, here we go again with a new edition of our weekly news review.

In the aftermath of last week’s GE annoucement the industry has a bit of a jump in its step. That was helped with news and announcements coming from IMTS 2016: loads of companies were showing off new and improved 3D printers and more. Predictably, much of it was on the Metal side, although Ingersoll and Oak Ridge also announced a very large composite machine. In other news, yours truly at Authentise had something to announce of our very own: the 3Diax Machine Analytics component of the 3Diax platform.

Let’s dig in.

 

Optomec Launches Line of Low-Cost, High-Value 3D Printed Metal Machine Tools

Authentise Releases 3Diax Machine Analytics – Real-time Status Monitoring for Additive Manufacturing

First tool to automatically monitor active prints and identify Key Performance Indicators is a key step to moving the technology from lab to production.

Mountain View, CA, September 12, 2016 – Building on the success of 3Diax (www.3diax.com), the modular process automation platform helping corporations industrialise additive manufacturing, Authentise has released 3Diax Machine Analytics.

Screenshot of Scheduling Page

3Diax Machine Analytics is the first off-the-shelf component of the 3Diax platform. It enables companies to monitor the status of all their additive manufacturing devices simultaneously, regardless of manufacturer. It also displays key statistics such as machine utilization and material usage on a convenient dashboard or Application Programming Interface (API). This gives companies the edge they need to acquire or maintain their lead. Using the system, customers will be able to increase throughput by quickly identifying available devices no matter where they are based, or reduce material waste by detecting inefficient printers or forgotten half-used material caches.

“You can’t improve what you can’t measure”,  says Andre Wegner, CEO of Authentise and Digital Manufacturing faculty at Singularity University. “Manufacturers and service providers who want to drive additive manufacturing to production scale know that they need operational transparency in real-time. 3Diax Machine Analytics provides it, but it’s just a start – using 3Diax’s other modules to build on the data enables measurable efficiency gain.”

A key element of 3Diax Machine Analytics is its extensibility with corporate IT systems, atop Authentise’s open API’s, or other elements of the 3Diax platform. Utilizing production data intelligently can yield more accurate quotes, automatic distribution of prints, or more efficient material inventory management, among other benefits.

“As the industry overcomes hardware, design and material challenges to identify more and more disruptive use cases for additive, the volumes rise exponentially,” continues Andre Wegner. “Current processes and software solutions are just not ready for that. 3Diax provides a modular solution that integrates and augments existing processes to address discrete automation challenges one-by-one rather than ripping and replacing the whole system.”

3Diax Machine Analytics, currently in beta, is available in the cloud or as locally installable solution. Many 3Diax modules (https://3diax.com/modules.html) have already been released publicly.

Week in Review: Aug 29th to Sept 4th – Going Big!

Here we go, another news roundup ready for you.

This week is all about bigger printers and printing BIG! As the race to faster, larger 3D printers gets more and more exciting, EOS is improving its products with more lasers, upgraded print volume and speeds that could rival Carbon3D; in metal this is kind of a big deal. It’s a Guinness World Record week for Oak Ridge and their massive 5m plane wing trim-and-drill tool. Talking big in AM one cannot avoid talking about the MX3D bridge over an Amsterdam’s canal, and now many other companies (and startups!) are bringing their robotic arm printers out to play, first Stratasys, now Branch Technologies with impressive lattice structures for concrete walls.

Without further ado, let’s dig into this week’s huge (pun intended) news.

Week in Review: August 22nd to 28th

Here’s our new weekly news roundup, this time we’ve got a bit of everything: big names announcing new 3D printers and partnerships, 4D printing developments and automotive customization on the horizon.

Let’s dig into it.

Stratasys launches two new 3D printers, partners with Boeing and Ford on applications

3d-printing-strat.jpg

Two new 3D printers from Stratasys could revolutionize aerospace and automobile manufacturing, the company announced Wednesday. The machines represent the next step in large-scale 3D printing for manufacturing, which experts say will completely change the field in the next decade. The Stratasys Infinite-Build literally flips FDM on its side, allowing you to 3D print on a vertical plane instead of horizontally, without size limits. It also operates at a speed 10 times faster than previously possible, Sevcik said. It can change in and out different types of material, with process control embedded in the system. Meanwhile, the Robotic Composite 3D Demonstrator enables automation of high-value composite parts for the aerospace and automotive industries, but also for industries such as sporting goods. The machine includes an 8-axis motion system, which uses precise, directional material placement to build strength while reducing or eliminating support strategies—rare for this type of manufacturing, Sevcik said. Stratasys also partnered with Boeing to define the requirements and specifications for the Infinite-Build to meet their needs for customized flight parts. Ford Motor Company is also exploring the machine’s abilities for car manufacturing, Stratasys announced.

Giving 3D Printing a New Dimension

A team of Lawrence Livermore National Laboratory researchers has demonstrated the 3D printing of shape-shifting structures that can fold or unfold to reshape themselves when exposed to heat or electricity. The micro-architected structures were fabricated from a conductive, environmentally responsive polymer ink developed at the Lab. While the approach of using responsive materials in 3D printing, often known as “4D printing,” is not new, LLNL researchers are the first to combine the process of 3D printing and subsequent folding (via origami methods) with conductive smart materials to build complex structures. In the paper, the researchers describe creating primary shapes from an ink made from soybean oil, additional co-polymers and carbon nanofibers, and “programming” them into a temporary shape at an engineered temperature, determined by chemical composition. Then the shape-morphing effect was induced by ambient heat or by heating the material with an electrical current, which reverts the part’s temporary shape back to its original shape.

Japanese 3D printed Copens could be customizable from 2017

Japanese automobile company Daihastu and 3D printer manufacturer Stratasys said last year that clients of Copen would be able to design and assemble customized 3D printed exterior panels. Recently they announced that the large-scale customization system is fully prepared and is waiting to be tested. At the moment, the Effect Skins have several different patterns and colors. All drivers could assemble and disassemble the panel according to their changing taste. It is said that there are totally 15 geometric and compound patterns to choose from. They are designed by the designers cooperating with this project. Besides, there are also 10 colors available. It takes about two weeks to change the color of their cars. Traditionally, this whole process could have taken as long as two to three months. What’s more, clients could even redesign their exterior panels, which means drivers of Copen could create unique “skins” of their own!

Russian researchers are building a drone powered by a 3D printed engine

VIAM, in collaboration with the Russian defense industry Foundation for Advanced Research (FPI) has announced it will be developing a drone that can be powered by a 3D printed engine that has also been developed by VIAM and which was unveiled last month. The small-scale engine is reportedly made entirely from 3D printed parts, weighs only 900 grams, and has a thrust of 75 kilograms. According to VIAM, the 3D printed engine’s thrust could also be increased by another 75kg with only a minimal increase in mass. VIAM, which began working with additive manufacturing technologies in 2015 for the construction of a combustion chamber swirler for an upcoming PD-14 turbofan, has found that 3D printing offers them a more precise and efficient way of manufacturing parts. For instance, using laser sintering technology and metal powder materials, VIAM has been able to produce parts 30 times faster than with traditional manufacturing methods and with a high level of precision. In terms of structure as well, 3D printing has opened to doors for what can actually be produced.

Week in Review: Aug 15th to 21st

Here we go again with the best news from this week’s AM world.

This week was all about the metal. I had 2 visits from startups perporting to be doing something radically new in the space to make it super fast or super cheap or both. In fact, come to think of it, we’ve been saying for a while that all the major investment in AM is going into metal:

Metal Dominates
Metal Dominates AM (c) Authentise

Another call I had with one of the major metal studios swore by Arcam “because they can put more power into their lasers”. Plus, all the top news we saw was about cheaper printers, expansion of metal print service providers (Norsk) and grants to solve some of the clear remaining challenges.  Clearly, there are exciting times ahead.

$50K 3D Metal Printer on the Horizon

Aurora a leading light in fast, efficient printing

The company, based in the aptly named Ambitious Link in Bibra Lake, is creating two types of metal 3-D printers which, it claims, consist of world-first technology that could change industry for ever. After 3 1/2 years, Aurora is turning its attention to life as a public company and is set to list on Tuesday after raising $2.8 million in an initial public offering. The company is completing the beta testing of its two small-format printer models with a view to moving into production by the end of this year. The small-format printers retail for under $US50,000. According to Mr Budge, a self-described robotics fanatic, the difference between its technology and the plethora of competing metal 3-D printers is it is cheaper and, for medium and large-format printers that are being developed, faster.

Norsk Titanium’s New Strategy for Metal AM, Brings Business to US

The NTi Technical Center in Oslo, Norway. (Image courtesy of NTi.)

While Norsk Titanium (NTi) was founded 2007, it wasn’t until the last few years that the Norwegian metal 3D printing company began attracting a lot of attention and investment dollars in the United States. That’s because, not only has NTi begun to expand its focus from 3D printing for the oil and gas industry to aerospace, but it has also started to work with a lot of big names, including Alcoa, Boeing, Airbus and, even, the State of New York. Chip Yates, vice president of Marketing at NTi, explained that NTi began with a lucrative career in the oil and gas space, working with the leading supplier of oil in Norway, but made the shift to aerospace when oil prices began to drop dramatically.

Yates pointed out that, unlike other metal 3D printing companies, NTi is not in the business of selling machines. Instead, the firm is a parts producer that leverages its RPD expertise to fill orders for its clients. According to Yates, this client list is actually quite a long one, and NTi is aggressively expanding the capacity to fulfill demand. For that reason, NTi has just opened a second MERKE IV manufacturing plant in Norway and will open an industrial-scale metal 3D printing facility in Plattsburgh, N.Y.

$350K to PITT Researchers to Optimize Designs for Metal AM

A team of researchers from the University of Pittsburgh’s Swanson School of Engineering and from Pittsburgh-based motion-control manufacturer Aerotech has recently been awarded a grant of $350,000 by the NSF to pursue their research and development of fast computational modeling systems for metal 3D printing. Metal AM is hard to design for because of the issues of distortions and stresses which can oftentimes arise when 3D printing complex geometries. In response to these 3D printing hurdles, the PITT research team led by Dr. Albert To is working on developing a both simple and accurate thermomechanics model which will help to predict residual stress and distortion in 3D printed metal parts. Once that phase of the research is complete, the engineers will then work on devising a topology optimization system that will be capable of generating 3D designs with both free-form and machining-friendly surfaces,

Week in Review: Aug 8th to 14th

Here’s our latest news roundup: we have a lot of tech related news as well as juicy reports and the latest statistics.

KPMG reports provide interesting insights in metal AM market

Screen-Shot-2016-08-10-at-14.04.29-906x767@2x

Two reports issued by KPMG provide useful insights into the manufacturing industry and how 3D printing companies may benefit from opportunities in this area. The latest report reveals that more than 50% of business executives either plan to invest, or have already invested in 3D printing. “Metals executives should have no concerns about their ability to source raw materials — for the time being, at historically low prices,” says Richard Sharman, KPMG’s global head of commodity trading. However, the processing of these raw materials into feedstock for use in 3D printing is an area where activity during 2016 is beginning to heat up.

Nanoscale 3D printing breakthrough in EBM technology

nanotube-1-906x906@2x

Researchers at the Department of Energy’s Oak Ridge National Laboratory have produced a process that could finally master Focused Electron Beam Induced Deposition and drive nanoscale 3D printing forward. Their findings were published in the journal ACS Nano in a paper entitled: “Simulation-guided 3-D nanomanufacturing via focused electron beam induced deposition.” FEBID has frustrated the best minds in the business and outside of a lab it has just proved impossible for anything larger than a few nanometers. But the researchers, together with a team from the Graz University of Technology, have developed a simulation to truly harness the process and open up a world of possibilities. One of the best examples that could benefit from this procedure is manufacturing of graphene sheets: a wonder material that could transform the technological world overnight but has yet to be produced reliably on a large, industrial scale.

BMW talks implementing in-house 3D printing

image003_agtb1v

Throughout its history, the BMW Group has been an early adopter of 3D printing systems, first leveraging early 3D printers for prototyping purposes and, more recently, for serial production. In fact, the Rolls-Royce Phantom features 10,000 additively manufactured parts, demonstrating BMW’s overall confidence in the technology and the ability to wield it. Jens Ertel, head of the BMW Group’s Additive Manufacturing Center, elaborated on the transition from 3D printing as a prototyping process to an actual additive manufacturing technology: “Due to our product portfolio, it was obvious for us to use 3D printing or, better, additive manufacturing for more than just prototyping. Subsequently, we started doing our own research on the materials and technologies. Based on these activities, we are continuously screening possible parts and try to find projects where a positive business case is given and where additive manufacturing fits to the specifications. Due to improvements in machine technologies and materials, we had the chance to do those further steps.”

Week in Review: Aug 1st to 7th

We’re back. The Week in Review took an Hiatus but we’re back for more. Send us any news you have.

Loads of funding news this time. 3D Hubs landed $7m from Europeans, Formlabs closed on $35m mostly from Foundry (congrats to both teams, so well deserved. Amazing mgt and product!). Siemens Oil and Gas bought what it didn’t already own of a print bureau in the UK (see below).

Formlabs was called out for moving towards the industrial, but there’s a world between Formlabs’ definition of industrial and Siemens’s. 3D Hubs also called out more professional focus in a sign of the times but as Authentise learned the hard way its tough to swing from consumer completely the other way in this industry. They are ostensibly different markets. What do you think the secret ingredients to an industrial transition are?

Vibration Absorption Through Lattice Structures.

3D-printed-lattice-structure-absorbs-vibrations-and-provides-support_popup-906x456@2x

Vibration absorption materials can offer good properties at the cost of stiffness and strength: now 3D printing can help solve this issue. Rigid vibration absorption lattice structures, created through 3D printing lattice of 3.5mm spacing and embedding steel cubes as resonators, provide efficient traps for vibration as well as high structural strength and optimal weight. Plastic and lightweight metals can be used, as long as the lattice structure and the resonators mass density ratio is preserved.

Raytheon Scaling up AM Deployments with $523m Missile Contract

rtn_250217

Arizona based Raytheon Missile Systems Co. got a $523 million contract from the Department of Defense for the manufacturing, test and delivery of 47 SM-3 Block IB missiles by the end of fiscal 2016. The contract could be replicated for a total of three option years and a yield of 52 missiles per option year. The contract is all based upon the company’s missile designs which incorporated 3D printing in many if not all aspects of manufacturing, including rocket engines, guidance and control systems and fins. Looking ahead, engineers at Raytheon are looking for effective ways to print electronic circuits and microwave components. “You could potentially have these in the field,” said Jeremy Danforth, a Raytheon engineer who has printed working rocket motors. “Machines making machines. The user could [print on demand]. That’s the vision.”
