3D printed cat tongue mimic could have applications for soft robotics industry

Nov 22, 2016 | By Tess

If you’ve ever been licked by a cat, you’ll know that their tiny tongues are actually quite rough, with a texture comparable to that of sandpaper. Unlike sandpaper, however, a cat’s tongue is abrasive because its surface is covered with tiny backwards facing spines called papillae, which have a number of useful functions for the cat, such as efficient grooming, scraping meat from their prey’s bones, and more. Recently, cat owner and mechanical engineering doctoral candidate Alexis Noel decided to explore the physiology of a cat’s tongue with the help of 3D printing to see if its spine composition could be appropriated for other applications such as soft robotics.

Noel’s research, which was largely conducted at the Hu Biolocomotion Lab at Georgia Tech, was presented at the 69th Annual Meeting of the American Physical Society’s Division of Fluid Dynamics (DFD), which is being hosted in Portland, Oregon. Notably, in her investigation of cat tongues and their functions, Noel actually 3D printed an artificial cat tongue at 400% scale for testing purposes.

What initially got Noel interested in recreating and exploring cat tongue functionalities was when she observed her own cat’s tong...

XJet aiming to revolutionize dental industry

Having recently launched a new technique for 3D printing metal with Nano Particle technology, XJet are also addressing ceramic materials. XJet showcased their latest capabilities at the Formnext trade fair in Frankfurt Germany, and the results look impressive. Xjet and their ceramic Nano Particle Jetting were briefly covered in 3DPI’s round-up of Formnext, however, this article will look at some of the implications and significance of this technology on ceramics and the dental industry in particular.

Ceramics are widely used in the dental industry, while patients do opt for metal crowns with gold and silver being an option, most patients seek ceramic solutions as they provide a more convincing look and blend in with other teeth. However, the traditional method of creating a ceramic crown can be quite tedious as it involves a number of different processes.

Once an impression of the patients teeth is made by the dentist using a dental tray which the patient bites into, this is sent to a Dental Laboratory for a technician to then create a plaster mold. Following this, the technician will build up a wax impression of ...

3D printing and scanning in schools gives life to biology

Schools in Victoria, Australia are now using 3D printing to understand biology like never before. This application of additive manufacturing allows young students to visualize the basics of anatomy by via 3D printed replicas of skulls and bones from a wide diversity of species. The Australian schools are using an online library called Diversity to access these models.

Wesley College is one of the first institutions involved in the effort. Principal Helen Drennen said 3D printers and 3D models are inspiring for teachers: “It’s encouraging everyone to be much more trans-disciplinary and connected in the way they learn and teach.”

Melbourne based company Anatomics is behind this project, encouraging the use of additive technology in schools to understand and explain biology. The company was founded in 1996 and specializes in manufacturing medical devices, patient specific implants, prosthetics and software solutions.

Formnext 2016 first look at new 3D printing technology

Formnext 2016 is open, and 3D Printing Industry bring you the first look at the latest additive manufacturing technology.

New machines unveiled

3D Systems have a large booth with a figure 4 modular configuration running, it will be interesting to see how this solution is adopted by industry and will be listening carefully for updates.

Another large area is taken by the UK’s Renishaw with the their path to industrialization showing the AM400 and AM500 machines. Roland DG Benelux are also here and have unveiled a binder jetting ceramic process. To fabricate the intricate ceramic pieces on display requires two machines, one to grow the part and a second to act as a kiln and cure the green part. The 3D ceramic printer will be producing green parts during the show, but the sintering phase will not be demonstrated.

Another company working with 3D printed ceramics, but also metals is XJet. XJet have a large area with the Nano Particle Jetting machine ready to draw a large crowd. The machine is also certainly large and speaking with Chairman of the Board, Yair Shamir this morning he tells me the company also have big plans. The incredibly intricate parts are really quite impressive and sure to generate a similar buzz as when the company appeared early this year at RAPID.

Fellow Israeli company Nano Dimension have a smaller booth in the startup up area, their DragonFly 2020 PCB prototyping machine is in the process of launching and will be available to users beyond the initial partners in 2017. The machine at Formnext will not be producing parts, but samples of the eagerly anticipated multilayer PCBs will be available. Including a 3D printed Arduino PCB.

Another European debut

Moving additive manufacturing to the industrial level looks like a focus for many here. Stratasys are again promoting their infinite build and robotic composite demonstrators but the working displays from IMTS are absent. Instead visitors can don a virtual reality headset and be transported to Chicago where the machines were last shown to the public. For Formnext the company are putting the greatest effort into the recently launched J750. Boasting soluble supports and vivid colors, ...

Rolls-Royce drive taste with bespoke 3D printing

In a conversation with Forbes Torsten Müller-Ötvös, Vice President and Director of Rolls-Royce, explains how he managed to save the company from its downward spiral in 2009. The success is due in part to the departure from determined taste-maker to bespoke manufacturer, and with that, embracing new technologies such as 3D printing.

As explored in last week’s article about the autonomous car/drone combo put together by 3D printed car makers Local Motors, the future of the automotive industry is in self-driven cars. Müller-Ötvös adds ‘Autonomous mobility means crashes won’t happen. That brings more freedom in how you design bodywork. We think better 3D printing devices will allow us to 3D print big body panels’.

Integrating carbon-fiber into the process is certainly on their minds too, as recently demonstrated by the Rolls-Royce i3 electric car. This subject was recently tou...

Amherst researchers use 3D printed teeth to study evolution of earliest mammals

Nov 14, 2016 | By Alec

Tooth-like structures can be found in vertebrates throughout the history of the world, and the ancestors of sharks and related fish species might even be the first to develop them from rough shapes on the jaw that could grind down food. Exactly because they are so common in so many species, teeth and jaws are a very important target for evolutionary biologists – as they can aid researchers in tracking the evolutionary process of various animals.

The only problem is that fossil evidence is almost never suitable for testing biological functions, and testing the effectiveness of various teeth structures (and effectiveness is always a driver of evolution) can therefore be quite difficult. But 3D printing is coming to the rescue. Researchers from the University of Massachusetts Amherst have developed a set of 3D printed teeth that were used to test the damaging ability jaws of the earliest mammals. Through this approach, they found evidence for the theory that the ability for teeth to damage prey is a much more significant reason for evolutionary success than bite force or the animal's energy expenditure.

In a nutshell, this 3D printing approach thus created a new analysis for evolutionary biomechanics studies. The 3D printed teeth themselves were based on the teeth of 200-million-year-old insect eating mammals, and could change the way natural selection is studied through dental morphology. Tooth shape is, after all, linked to diet and feeding and a lot of knowledge of early mammal evolution is already derived from dental studies. The Amherst findings are published in the latest edition of the British Royal Society journal.

This breakthrough was realized by evolutionary biology doctoral student Andrew John Conith and his su...

Lightest: the levitating lamp you can customize with 3D printing

Nov 12, 2016 | By Tess

A nice light fixture or lamp has the uncanny ability to tie a room together, giving it warmth, a fun vibe, or whatever ambience you are seeking. “Lightest”, a new 3D printed lamp being featured through a Kickstarter campaign is not only all of these things, but offers a whole lot more. Developed by Barcelona-based startup Base Forge, the impressive lamp is not only a stately piece to feature in your home, but is customizable and most excitingly of all, is actually capable of levitating.

Lightest, which in its standard form looks like a magical glowing crystal ball, is a wireless lamp that with the help of magnets can levitate just above its base. The lamp itself is powered by induction, a process through which a small electric current from the base is transferred to the light.

The innovative new light, aside from being a great conversation starter, is also practical as it can be controlled by remote control and ...

Robot Factory combines 3D printing with 3D FORMING thermoformer for desktop mass production

Nov 10, 2016 | By Alec

When placed alongside each other, the different benefits of both 3D printing and molding are obvious: 3D printers fit on your desktop and allow for unique and intricate creations, while molding is much quicker but only cost-effective for very large batches because the molds are so expensive to make. Why not combine the best of both worlds? That is, in a nutshell, what Italian making experts Robot Factory are now advocating. They are now launching the 3D FORMING thermoforming machine, which allows you to quickly make (food-friendly) molds from any 3D printed object. Perfect for transforming your desktop into a mini-factory.

It’s exactly the type of making innovation that can be expected of Robot Factory, who have previously successfully launched several desktop machines that add a whole new dimension to making. Back in 2015, they did the same with Copperface kit for coating plastic or resin 3D printed parts in metal. They also manufacture several 3D printers, including the 3D One FDM 3D printer and a series of 3DLPrinter SLA models.

This newest machine is especially interesting because it brings a very commonly used industrial technology to your desktop. In a nutshell, thermoforming is a proces...

Ulticast – 3D printing for soft robotics

A team of students at Delft University of Technology have successfully modified an Ultimaker 2 machine in order to cast silicone inside a 3D printed mold. The technique was unveiled by the students at the dutch university’s Science Fair. They’ve coined the technique ‘Ulticast’ and it has positive ramifications for the soft robotics industry. The concept involves creating a mold and 3D printing inside it simultaneously. The casting mold is created using water soluble Poly Vinyl Alcohol (PVA) requiring the final 3D printed form to be submerged in water following its print in order to remove the cast.

This patient defied doctors and 3D printed his own heart

Nov 9, 2016 | By Benedict

After being diagnosed with Marfan syndrome, a disorder which affects the body's connective tissues, engineer Tal Golesworthy refused to undergo invasive and risky preemptive surgery. Instead, he recruited two doctors to 3D print a replica of his heart and make a special corrective device.

British engineer Tal Golesworthy

For over 30 years, British engineer Tal Golesworthy lived with Marfan syndrome, a life-threatening condition affecting his aorta. For most healthy people, the aorta stretches to accommodate blood flow before relaxing back to its previous size; for Golesworthy, doctors warned that his aorta would struggle to shrink back to size and would continue to enlarge over time—one day, they said, it might burst. In 2000, doctors told Golesworthy that the time had come to perform preemptive surgery.

Doctors told Golesworthy that the stretched section of his aorta would need replacing with an artificial graft, with metal valves possibly required. After the operation, Golesworthy would have to take blood-thinning drugs which could put him at a high risk of bleeding. Faced with this daunting proposition, Golesworthy simply declined, and went home to think about other solutions. The engineer, with no medical experience, decide...

3D printed vertebrae surgical guide helps Indian doctors treat ten year old scoliosis patient

Nov 7, 2016 | By Tess

As the technology continually develops, 3D printing is quickly making inroads within the field of healthcare, being used for various medical applications. While its uses for manufacturing implants and prosthetics are still relatively experimental (though significantly on the rise globally), additive manufacturing has proved exceptionally useful for the production of custom surgical guides and bespoke models. Recently, a hospital in the Indian city of Mumbai demonstrated how critical 3D printed surgical guides can be.

In September 2016, a young ten-year-old girl suffering from severe scoliosis was brought into the Lilavati Hospital in Mumbai for a revision scoliosis surgery. Scoliosis, a condition which causes curvature of the spine, affects many people around the world. Many can live with it, though severe cases can be impeding and even affect one’s breathing and mobility. Treating severe cases can be very complicated as well, as the process often requires doctors to implant screws and wires into the spine to straig...

3D Systems to get aggressive, Q3 earnings update

When 3D Systems Corporation (NYSE:DDD) CEO Vyomesh “VJ” Joshi  met earlier today with analysts and investors he was, as usual upbeat about the future of 3D printing and his company. However, investors hoping to get rich overnight might not share the same time horizons. Since taking the helm at 3D Systems, VJ has brought in a new level of senior management and began to target cost-savings across the business. A key word in his strategy is focus.

As always VJ  took time to answer a long list of questions from analysts keen to understand the business and the call lasted over an hour. VJ says that 3D Systems are at inflection point in AM, and believe the company has the infrastructure to “make 3D printing real.” While recent share price performance has been decidedly average, as often pointed out on 3DPI this is rarely a useful metric to appraise a company.

For VJ “A key priority is reducing cost of sales,” however making changes in the cost structure are actions that will not become evident until 2017. During today’s call significant growth was promised, but this will be a long term journey.

Highlights from the Q3 results show an increase in revenue to $156.4 million, from $151.6 million for the same period in 2015. Operating expenses have reduced to $91.0 million and operations generated a loss of $22 million versus $34.6 million for Q3’15.

 

Key Verticals

In one one of the most actively watched areas of 3D printing, metal the company did not provide the level of granular detail some analysts wanted. 3D systems do not break down revenue to the level of material type, but VJ said that GE’s entry into the metal space, “validates” the technology. One analyst suggested that metals might constitute less than 10% of revenue at 3D Systems, however the CEO would not be drawn on providing a number.

The two key verticals in metals are medical and healthcare. For the healthcare vertical VJ is keen to replicate this model, and its success in the other sectors 3D Systems operate in.

CFO John McMullen characterized the recent quarter as a “careful” approach. Information about cost reduction efforts will be forthcoming in 2017, also investments in IT will be announced. These efforts around cost structure are just getting started according to the company.

Update on Figure 4

During the most recent reporting period 3D Systems have continued to rationalize their product portfolio and, as illustrated by the Figure 4 modular system, are looking at ways to recombine their wealth of IP in new ways.

Troy Jensen at Piper Jaffray asked about Figure 4, and was keen to learn when will it be available. On today’s call there were, “No specifics on the release, but since IMTS we have seen signifi...

3D Hubs CEO speaks to 3DPI about acquisition of Printivate and the future of 3D printing

We asked 3D Hubs CEO & co-founder, Bram de Zwart, for his thoughts about today’s news that 3D Hubs has bought 3D optimization company Printivate and what the next steps for the company might be.
“So the 3D printing ordering process has always been a very cumbersome process. I’ve tried the old fashioned way, through email, and it typically took me 2 days and about 10 emails to get to the production step. So being an online platform is about making the process a simpler and a lot easier,” de Zwart tells me.
While some companies are making steps in this direction de Zwart says, “it was always very hard for a customer to check if a file was printable. That’s why we made the acquisition because we are in a unique position to lead”
I asked the CEO how the two businesses will be integrated, and whether Printivate will be rebranded as 3D Hubs.
“Printivate with become part of 3D Hubs and that means all the intellectual property they have developed and their founder and CEO (Adrian Muresan) will all become part of our team.” The intention is to integrate the Printivate and simplify the online ordering process by optimizing files for 3D printing.
De Zwart confirmed that 3D Hubs have spent a while looking at the market for a company that would make sense as a strategic acquisition.
We’ve looked at different options there, and we found that Adrian is a really smart guy and has built amazing technology. So we felt Printivate were the best candidate to become a part of 3D Hubs.

Printability features

The integration of Printivate into 3D Hubs will take place over, “multiple months and once what [Adrian] has built over the past couple of years is integrated he will continue to work as our R&D lead and continue ...

ORNL 3D printed incredibly power permanent magnets outperform conventional magnets

Nov 2, 2016 | By Andre
The first thing many of us think of when we hear the word magnet is that horseshoe N-S bar from elementary school science class. The truth is that the world we live in relies heavily on the power of these opposing forces in motors, generators, speakers, trains, TVs, cranes and compasses for navigation.
They are in no uncertain terms paramount in driving the technological systems that surround us so when Oak Ridge National Laboratory announced their 3D printed permanent magnets outperform the conventional variety well, I’ll take that as another victory for additive manufacturing.


A permanent magnet is one that creates its own persistent magnetic field and therefore keep going without the need for any recharge. A good example of one is found in your refrigerator door for example. Pull open as often as you want and it will always snap back shut with ease.
The Department of Energy’s Oak Ridge National Laboratory study created their 3D printed magnets by blending magnetic powders with a polymer as a binder and then by depositing the material into its preferred shape using several commercial processing methods including extrusion.
And while the idea of 3D printing a powerful magnet might be new to many, it is further evidence that the technology is being adopted by more and more faculties around the world is growing steadfast.

Composite pellets are melted, compounded, and extruded layer-by-layer into desired forms. 

Liang Li, ORNL research and study co-author suggests that “manufacturing is changing rapidly, and a customer may need 50 different designs for the magnets they want to use. Traditional injection moldi...

UPENN students 3D print Piccolissimo, worlds smallest self-powered flying robot

Nov 1, 2016 | By Andre


There are extremes in just about every topic one can think of. From the smallest atom to the vast universe that surrounds it or the 3D printing of houses versus an emerging trend of tiny 3D printed robots; important discoveries can be witnessed at every scale.
A team of researchers at the University of Pennsylvania’s School of Engineering and Applied Science have recently focused their efforts on one of these ends and 3D printing was essential in accomplishing their goal of making the smallest self-powered controllable flying robot (named Piccolissimo after the Italian word for “tiniest.”).


The robot itself comes in two sizes. The lighter of the two weighs in at 2.5 grams and is about the diameter of a quarter. Its larger sibling, about 2 grams heavier and a centimetre wider has the important advantage of being remote controllable. And considering Piccolissimo only has two moving parts (a propeller and the body itself) that’s rather impressive.
Matt Piccoli, the team’s lead notes that “the body spins around 40 times per second, while the propeller spins about 800 times per second. Since the propeller is mounted off-center on the vehicle body, the propeller’s center, and therefore the location of its thrust, also spins around 40 times per second.”

This process of control doesn’t sou...
