3Doodler: The World's First 3D Printing Pen by WobbleWorks LLC. Eventorbot Open Source 3D Printer. Watch and Learn: There's More Than One Way to Additively Manufacture a Metal. Posted by Ray | 22 Aug 2012 | Comments (5) Earlier this week, when I posted a video about 3D-printed bike parts, I was simply too excited about the prospect of digitally fabricating dropouts to concern myself with the technology behind the collaboration between Charge Bikes and EADS. Commenter Modul called me out on my lack of due diligence, piquing my interest in a process known as DMLS, short for Direct Metal Laser Sintering.

Had I done my research, I might have dug up commenter Lori Hobson's mention of "DMLS, a process for METAL, even titanium!!! "... in response to a 2008 (!) Post on rapid prototyping. It turns out that Hobson, at the time, was at product development consultancy MindTribe, and she'd recently learned about the process herself. Which brings us to 3T RPD, who provided the images in Hobson's post (reproduced here). As 3T RPD notes, the EOS M270/280 is more or less the industry standard for DMLS machines... at least to the extent that they've made their way stateside.

MakerBot. Your 3D design turns into reality with the 3D printing. NEWS FROM THE FUTURE: Reconstruction Sphere Makes Digital Copy of Anything. Reconstruction sphere makes a flawless digital copy of anything… @ DVICE - The OrcaM Orbital Camera System will take any object placed into its maw and create a submillimeter accurate 3D model, complete with color, texture, and reflectivity maps.

Seven individual cameras orbit around the sphere with the object inside it, taking simultaneous high resolution pictures while different combinations of projected light and shadow are used to help define object geometry. It’s completely automatic, and when OrcaM is done taking pictures, you can pull the original out unharmed along with a perfectly rendered digital copy. I think there’s a DIY-style way to make one of these with a few hacked Kinects, maybe not this round of hardware but certainly the next.

Twin Rail Mobius can-take-a-ball - Pendant by stop4stuff on Shapeways. Inspired by the well known mobius strip (discovered by August Ferdinand Möbius in 1858), an interest in the unusual, and 3D modelling, I created the Twin Rail mobius pendant. A half shell and 3 rails form a bearing-like structure to encapsulate a train of 6mm balls in a mind-warping cage with a twisting, fascinating movement bringing to life the only pendent of its kind in the world. Includes a 4mm loop for attaching to a necklace or leather cord.

See the photographs with retro-fitted 31 6mm chrome steel ball bearings... in the bottom photo, the balls have been heated until they 'blue'... check out the video to see how they move by clicking on the little icon below the camera above. Also available smaller and in silver, Twin Rail Mobius Pendant - small Note: this item is the shell alone, you will need to aquire and fit the balls (31 x 6mm or 29 x 1/4 in) as well as a suitable necklace to hang it from, a 3mm leather cord works well. 3D printing gets more flexible with Nylon extrusion.
