3D printed titanium parts

[Dr. Steve Brule]

I'm dubious but if it works well it's pretty amazing. I'd rather have a version that has a lamp already fitted so your phone battery doesn't get rinsed by having it on full brightness for hours.

Like you wouldn't just send secret dicks to everyone.

I kind of struggle to see how a phone screen can fling out enough light to cure resin quickly and accurately enough, when our little sla machine uses some sort of death laser and still takes a while... Cool if it does work though.

I'm very sceptical. Any resin that is sensitive enough to harden reasonably quickly on the light from a phone will be a pain in the arse to keep out of daylight. Their video shows it in clear bottles in full daylight which seems mad unless you mix it up with some sort of catalyst just before use. I think the reality would have to be dark rooms etc.

I haven't seen it/that video until now.

Paused at ~12 seconds in to log in/post this.

the music, the voiceover, the actors... seems fake, like an snl sketch


just finished it.  I can get deep into conspiracy/surveillance stuff about how it might definitely eventually be possible for phones to do this -  apple patents for camera lenses/sensors between pixels, laser stuff, iris/retina/finger tracking stuff, etc - but I'm pretty sure this is just another 'microwave your phone to charge the battery instantly' type of thing, getting people to cover their phones in resin.  I also don't believe that those guys are italian...

I'd be psyched if it's real, especially for the potential metal casting stuff, but it feels like a setup for a shitty old joke...

The metal casting really isnt a big deal, you can do that with pretty much any plastic 3d print.

point being that A LOT more people have smartphones than 3d printers.  It'd be more accessible, more people would be doing stuff with it/making advancements.  Easier for more people to get artsy/experimental...  progression/expansion.  Not creating anything new, just making it more accessible/cheaper for others to do it.

I'm cheap as fuck and I want this to be as easy as possible...

Airbus APWorks unveils 35kg 3D printed electric motorcycle

APWorks, a subsidiary of Airbus Group, has built a fully functional 3D printed motorcycle. The vehicle, which has been dubbed the ‘Light Rider’, is made from APWorks’ Scalmalloy material and weighs just 35kg.



Ever since APWorks first announced the creation of Scalmalloy, a high-strength aluminum-magnesium-scandium alloy, the Airbus subsidiary has been keen to show off exactly what the material can do. First came this super-lightweight, 3D printed airplane partition, and now an entire vehicle has been made from the stuff. The Light Rider is, admittedly, smaller than your typical Airbus vehicle, but before the aerospace giant 3D prints half its future airplane fleet, this 3D printed motorcycle, unveiled today in Ottobrunn, Germany, demonstrates just why Airbus and APWorks have so much faith in the potential of Scalmalloy. “With the Light Rider we at APWorks demonstrate our vision of future urban mobility,” said engineer Stefanus Stahl.

Weighing in at just 35kg, the 3D printed Light Rider is around 30% lighter than conventionally manufactured e-bikes, can zoom from zero to 45km/h in just three seconds, and has a top speed of 80km/h. The secret to the impressive bike is its 3D printed frame, which weighs just 6kg, part of the reason for the vehicle’s 60km battery life. Although its appearance might take some getting used to, the topologically optimized structure of the frame is designed to eliminate mass where it is not required. APWorks actually developed a special algorithm, inspired by bionic structures and natural growth processes, to work out where material could be eliminated and where it needed reinforcing. The result is a skeletal, almost organic-looking structure, with not a gram of surplus material in sight.

According to APWorks, the lightweight, optimized, 3D printed frame could not have been produced using any other manufacturing technique: “The complex and branched hollow structure couldn’t have been produced using conventional production technologies such as milling or welding,” explained Joachim Zettler, CEO of APWorks. “Advances in additive layer manufacturing have allowed us to realize the bionic design we envisioned for the motorcycle without having to make any major changes. With these technologies, the limitations facing conventional manufacturing disappear.”

APWorks has worked at the forefront of additive layer manufacturing (ALM) and advanced materials since its launch in 2013. "3D-printing technologies have revolutionized the design and manufacturing process – not only in terms of structure and aesthetics, but also in impressive weight savings on parts and equipment," says the company.

To create the incredible 3D printed frame, APWorks used a selective 3D laser printing system to distribute the Scalmalloy powder in layers just 60 microns thick. By 3D printing these parts, APWorks was able to create unusual shapes and reduce mass, while also reaping the other rewards of a bottom-up manufacturing approach: many of the Light Rider’s 3D printed frame parts are hollow, which allowed the designers to integrate cables, pipes, and screw-on points directly into the motorcycle body.

Scalmalloy, the aluminum-magnesium-scandium alloy used by APWorks to create the Light Rider’s frame, is a corrosion-resistant material which purportedly exhibits titanium-like strength. Designed specifically for additive manufacturing purposes, the material combines strength with a high level of ductility, making it ideal for robotics, aerospace, and automotive 3D printing projects.

APWorks plans to build 50 more Light Riders, available to buy for €50,000 each. A €2,000 deposit is required to join the waiting list.

Lugged titanium creation showcases 3D printed tech
http://www.bikeradar.com/road/gear/article/mirada-pros-3d-printed-titanium-frame-47160/

June 01, 2016

Here we have what is undoubtedly one of the most advanced bicycle frames ever created – and yet you’ve probably never seen or even heard about it.

Produced as a joint collaboration between UK firm Mirada Pro, tubing specialist Reynolds and framebuilder Ted James Cycles, the frame is currently a one off that demonstrates a new direction for the people behind Mirada Pro.

Taken from design to manufacture in just eight weeks, the frame uses multiple 3D-printed titanium lugs that are welded to custom titanium tubing from Reynolds.

The frame has yet to be ridden and is currently awaiting EN testing

Look closer and you’ll see 3D printed titanium lugs make up the head tube, bottom bracket, dropouts and top tube/seat tube intersection. These lugs have been welded to custom drawn titanium tubes from Reynolds in a 53cm frame that emulates the geometry of a traditional alloy road bike. The result is a sub-1kg (999g) frame that Mirada Pro claims offers improved torsional stiffness over a comparable alloy item.

The design also allows for welds to be moved away from high stress areas, and for the surfaces destined for welding to be simplified. Less parts and reduced machining times mean that manufacturability should be improved while costly tooling can also be done away with.

The potential of 3D printing in bicycles is yet to be fully realised but below is a decent example of how the technology has made a big impact among other industries – this one's from the world of aerospace.

(L) CNC part is 50% heavier and wastes 68% more material than the 3D printed component (R)


The metal component to the left was traditionally CNC milled from a large titanium billet. On the right is the redesigned version of the same component, and one that’s optimised for 3D printing. Compared with the original design, the 3D-printed part offers the same strength and stiffness but is 50% lighter. Better yet, the economy of the process is on another level: the CNC process producing a remarkable 70% of waste material compared to just 2% from the 3D printed part.

...

In the case of this frame, Mirada Pro used the load figures a frame needs to achieve in order to pass EN safety tests, which engineers then input into their CAD program. The program then interpreted how much titanium powder needed to be where in a formation that would provide the correct strength but with minimal material. Just take a glance at the CAD drawing below and you’ll notice large vein-like structures that pass through the design. These structures have largely been depicted by the software used to design the frame, and you can see directly how they translate to the finished components..

...

Titanium actually works out to be the cheapest material that Mirada Pro works with, even though the machines are capable of producing identical parts from alloy or stainless steel, both would be considerably more time consuming in the printer, remember - time = money. In fact, printing with aluminium takes twice as long as it does with titanium...
