3D printing cuts replacement time and cost at Daimler buses. From full-size buildings to fashion items, 3D printing is breaking down the barriers usually associated with manufacturing fiddly low-volume products.

3D printing cuts replacement time and cost at Daimler buses

Now, Daimler has turned to the process for replacement parts in buses. The move allows complex interior components to be economically made in small batches, with shorter turnaround times than possible using conventional production methods. This isn't the first time Daimler has turned to 3D printing for replacement parts – last year, the company announced it would be using Selective Laser Sintering to produce 30 plastic truck components. Before that, the process was also used to develop more than 100,000 prototype components. When a bus operator needs a specific replacement part, they simply need to order the part based on its specific order code.

It isn't just simple, single-piece components that Daimler is printing. Novel 3D printer puts continuous printing on the table. At the heart of many of today's 3D printers is a stationary print bed, which means that if you want to print a really, really long object like a company logo for above the office door or hollow tubing, it would likely take several print runs and some glue.

The BlackBelt from Stephan Schürmann replaces the print bed of old with a conveyor belt, which allows for continuous printing. Currently the subject of a Kickstarter funding campaign, the BlackBelt has been 3 years in development – going for CAD-modeled concept to prototype to production ready. Its carbon fiber composite conveyor belt allows for continuous printing of long objects, with the option of going really, really long by placing a roller module unit in front of the conveyor belt, or continuous batch production of smaller single build parts, which can be collected in a bin at the end. 3D Printing with plants is cheaper, stronger and more environmentally friendly. Engineers at MIT have developed a way to use plant cellulose as a feedstock for 3D printers, providing another renewable, biodegradable alternative to popular petroleum-based polymers like ABS currently being used.

The researchers also believe printing with cellulose could be cheaper and stronger than other materials and even offer potential antimicrobial properties to boot. "Cellulose is the most abundant organic polymer in the world," says MIT postdoc Sebastian Pattinson, lead author of a paper describing the new technique. "Cellulose and its derivatives are used in pharmaceuticals, medical devices, as food additives, building materials, clothing – all sorts of different areas. MIT applies soft touch to robots with programmable 3D-printed skins.

Spectators of the DARPA Robotics Challenge finals in 2015 would have noticed that many of the competing robots were padded up for protection in case they took a tumble.

MIT applies soft touch to robots with programmable 3D-printed skins

MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) is looking to build customizable shock-absorbing protection into robots by using 3D printing to produce soft materials that not only dampen the impact of falls, but also allows them to carry out safer, more precise movements. Robotics engineers have long had a keen interest in soft materials. At their simplest, such materials can protect robots against falls and collisions, but can also protect people in environments were robots and humans are increasingly working together.

This is the first object 3D-printed from alien metal. But today Planetary Resources is showing that it can do the last item on that list: building with metals not from Earth.

This is the first object 3D-printed from alien metal

At its booth at CES this year, the company is showing off a 3D-printed part that was made from a material not of this planet. Specifically, the company took material from a meteorite that landed in Argentina in prehistoric times, processed it and fed it through the new 3D Systems ProX DMP 320 direct metal printer. Ultimaker 2 3D printer pushes the limits of speed and accuracy. Ultimaker, which was born in 2011 as an outgrowth of the RepRap project, and which quickly grew to become an important player in the home consumer 3D printing market, has announced its second generation 3D printer.

Boasting improved reliability, user-friendliness, and an increased print volume. "We are an independent company, we don't have outside investors," explained Erik de Bruijn, Ultimaker co-founder, at the Ultimaker 2's public unveiling. "I think if we can all start to see the world not as a fixed thing, but as an environment that we can actually shape together [...], building on top of each other's work, then it would be a very big irony if the devices that we used to do that [...] would be a closed environment. Wacky tape gun produces life-size CAD-assisted wireframe models.

Using a handheld packing tape dispenser gun that has been modified to fold, extrude, and cut tape into tubes, a team of researchers from the Hasso-Plattner-Insitut (HPI) at the University of Potsdam has created a method of transferring computer-generated wire-frames to the real world.

Dubbed the "Protopiper" by its creators, the device is not only capable of producing full-size outline objects, it is also able to produce hinges, bearings, and axles to give them opening doors, drawers, and movement just like the real things. Thinking outside the square, the team from HPI sought a better, cheaper, quicker way to produce real-world wireframe models than the usual plastic tubes.

Standard plastic packing tape was the team's solution. New 3D-printing tech set to enable patient-specific medical devices. Most medical devices come in standard sizes, but people – as you've probably noticed – vary widely in their shape and size.

Sick or premature babies especially can run afoul of this system, as their tiny bodies leave much less room for error in inserting or attaching devices at the correct spot. But in the near future all biomedical equipment may be 3D printed at precise dimensions to suit each patient. Researchers at Northeastern University are developing a 3D printing technology for exactly this purpose. Their method uses ultralow magnetic fields to precisely align ceramic fibers with liquid plastic in a similar way to how the human body orientates calcium phosphate fibers in bone around blood vessel holes – in the process reinforcing the bone's strength.

If the fibers are not aligned parallel to the direction of stress/geometry, the structure is left weak and may not withstand the force of oxygen, fluid, or nutrients flowing through it.

The technology itself has also evolved and is now being implemented in a vast range of industries from food to automotive, aerospace, construction, health and many others. MultiFab mixes and matches 10 different materials in a single 3D print. 3D printers may have come on in leaps and bounds in recent years, but most are one trick ponies in that their computer-controlled syringes extrude only one material at a time to build up an object. It's a process that's slow, imprecise, and often requires items to be printed in separate pieces and then assembled. Watch: This new type of 3D printing was inspired by Terminator 2. This new 3D printing technology looks like science fiction. But it's entirely real — the scientists who created it took inspiration from the futuristic liquid metal in the movie Terminator 2.

Joseph DeSimone and the other University of North Carolina scientists who describe the technology in a new paper published today in Science call it "continuous liquid interface production. " (They've also founded a new company called Carbon3D to sell the printer.) 3D Printing an Earbud Holder with Dremel's 3D Idea Builder.

3D printing has always been heralded as a world-changing technology. But until recently, gaining exposure to this cutting-edge space required a level of know-how beyond the average DIY tinkerer’s grasp. The Dremel 3D Idea Builder is designed specifically to make this powerful technology accessible to casual consumers. Wonder-ink could soon let you 3D print objects out of stretchy graphene. A new 3D-printing ink being developed at Northwestern University could soon make it possible to build objects which are made of graphene for 60 percent of their volume and 75 percent of their weight. This unprecedentedly high graphene composition means that the oft-praised electric and mechanical properties of graphene might soon find their way into all kinds of macroscopic 3D-printed creations, with important consequences for the electronics and biomedical fields (among many others).

While we've already seen 3D printers that can create objects out of carbon fiber, the ability to print objects made mainly out of graphene could raise the bar even higher for material scientists and hobbyists alike. Previous graphene-based inks could only print objects in two dimensions and, with a graphene content below 20 percent, were unable to preserve the useful properties of the material. The stretchiness of the material can be controlled by the percentage of binder used. History, Travel, Arts, Science, People, Places. L'Oreal to start 3D-printing skin - BBC News. French cosmetics firm L'Oreal is teaming up with bio-engineering start-up Organovo to 3D-print human skin.

It said the printed skin would be used in product tests. Organovo has already made headlines with claims that it can 3D-print a human liver but this is its first tie-up with the cosmetics industry. Experts said the science might be legitimate but questioned why a beauty firm would want to print skin. L'Oreal currently grows skin samples from tissues donated by plastic surgery patients. It produces more than 100,000, 0.5 sq cm skin samples per year and grows nine varieties across all ages and ethnicities. 3D-printed spine cage enables customized spinal fusion surgery.
