Recycled fridges deliver sustainable 3D printing

Plastic recovered from discarded fridges is being re-purposed into a resilient material that can be used in the 3D printing of scale models and similar outputs. The development follows a partnership between two Dutch specialist, Coolrec, a subsidiary of Renewi, and filament manufacturer Refil.

Refil already makes a range of different coloured filaments from recycled car dashboards and PET bottles. Now it is taking the interior of fridges supplied by e-scrap specialist Coolrec to make High Impact PolyStyrene (HIPS) filament that has a neutral off white colour which is easy to paint or glue, making it a perfect material for the 3D printing of scale models. The filament comes in the two standard diameters of 2.85mm and 1.75mm and has successfully been tested on 3D printers.

Modular 3D printer builds sustainable houses using locally-sourced materials

Some companies that make 3D printersstick to desktop-sized units. WASP is not one of them. They do it all, from filament-fed units to giant machines that print whole buildings.

In 2015, WASP introduced the 40-foot tall BigDelta. They used it to print a basically zero-cost adobe home in about three days.

Last week they unveiled the newest addition to their lineup. It’s called the Crane WASP and it can print much larger and more complex structures.

3D printing with recycled plastic to replace soldier’s supplies

US military researchers have developed a way to use recycled bottles and other refuse materials to 3D-print replacement parts for soldiers in the field.

US Military 3D printed bracket

Military personnel stationed around the world often have a long wait when they need a critical replacement part. Now, the US Army Research Lab (ARL) and the US Marine Corps have partnered to develop a way to kill two birds with one stone by recycling the plastic bottles and bags the military uses and 3D-printing needed materials in the field.

Nicole Zander, a researcher at ARL, and US Marine Corps Capt. Anthony Molnar are working on a joint project to break down recycled polyethylene terephthalate (PET) plastic into filament to use as a starting material for 3D printers. The material then can be fabricated into plastic parts for radios, canteens, and other items soldiers can use in the field.

Machine learning “fixes” 3D-printed metal parts—before they’re built

Neural networks and advanced algorithms use real-time video to analyze build quality and advise on how to improve it.

3D defects

For years, engineers at Lawrence Livermore National Laboratory  have used sensors and imaging techniques to analyze the physics and processes behind metal 3D printing in order to build high-quality metal parts the first time, every time. Now, they are leveraging machine learning to process data obtained during 3D builds in real time, detecting within milliseconds whether a build will be high quality. More precisely, they are developing convolutional neural networks (CNNs), a type of algorithm commonly used to process images and videos, to predict whether a part will be good by looking at as little as 10 milliseconds of video.

Interview with Fabian Alefeld of Additive Minds on 3D printing training, consulting and application development

One of the things holding 3D printing back is the lack of Application Development Consultants. Imagine the dawn of the asphalt age, bitumen production increases as maps are filled with squiggly lines where fields once stood. Cars roll off of vastly expanded production lines while workers who built them on cue, queue in lines for new automobiles. Where do we see the constraints of this automotive revolution? We don’t really see them at the time, just like we can’t fathom the effects. Decades on suburbs emerge, nations have changed and the citizens of the first world are all connected by a web of white lines on hardened petroleum, a new future being patrolled by cars propelled of earth’s crust cured dinosaur. We are, I believe, at the forefront of just such a revolution. But, rather than connecting all the points of the known world we will connect all the points of our imaginations with the makable.

10 questions brokers should ask clients about 3D printing

With the rise of additive manufacturing (AM), a wide range of users now have 3D printersat a keystroke, and can produce physical objects without the use of traditional manufacturing tool and die fixtures or injection molding.

Inexpensive parts for everyday goods, for example, are now being produced with affordable 3D printers and then sold to consumers by individuals or small businesses.

On the other end of the 3D printing spectrum, aerospace, automotive and medical device companies are innovating with machines costing upwards of $1 million.

3D printing: how to overcome product liability risks

Germany is developing a distinct competitive edge in this emerging technology. But the realisation phase of this new tech’s life cycle has brought with it many questions concerning product liability and more.

3D printing

From spare parts for the automotive sector to aircraft components and consumer goods, 3D printing technology can be produced quickly and inexpensively, with the added benefit that items can be more easily personalised.

German chemical giant BASF is among those taking significant strides in additive manufacturing and is collaborating with a growing network of organisations in an effort to take the applications of 3D printing beyond the prototype phase.

What lies ahead for 3D printing?

As 3D printing starts to bridge the gap between prototyping and production, some companies are looking at streamlining CAD software, and making it more accessible.

3D design and printing technology has advanced at an alarming rate. We can now print complex objects from different materials, in different colors, in rapid time — even in the comfort of our own homes.

Then there’s the varied commercial applications for 3D printing (3DP). One survey of US manufacturers found that two out of three companies are already adopting 3DP in some way. Some of these companies include General Electric, Nike, Airbus, Amazon, Hasbro, Hershey’s, Boeing, and Ford. And we hear countless stories of 3D-printed houses, cars, aircraft components, musical instruments, shoes, robots, and body parts, just to give a few examples.

Common processes and materials in 3D Printing

3D Hubs’ Q2 report shows what 3D printing processes and materials are being used and where.

3D printing

In our previous coverage of 3D Hubs’ Digital Manufacturing Trends Q2/2018 report, we talked about the top-ranked 3D printers. However, the company kept tabs on more than just printers. By tracking all data on its platform, 3D Hubs has helped shine a light on the state of 3D printing itself. While powder bed technology is poised to grow, currently extruding standard black PLA is dominating this one online platform.
