Chris sez, "The oft-touted promise of 3D printing is of personalisation and customisation. There is an alternative use though which is that of mini and micro-manufacture, where production runs of things numbering hundreds and thousands are suddenly made possible and in some cases commercially viable.
"We're investigating this space as a new way of manufacturing model kits, using laser scanning to get the data for the prototypes to make the kits very accurate. The financial advantage of 3D printing in producing kits at whatever scale people want to model in, often from the same file, is huge and makes the creation of very niche items viable. We're experimenting with crowd sourcing what potential kits to explore and using crowd funding to decide what to focus on and make."
Chris and co are scanning full-sized railroad engines at insane resolution.
We realised though that some things that you want to model were too complex even for incredibly talented CAD model makers like Vijay to create perfectly just from photographs, or at least that the time taken to produce the model would be too long and the process of checking the model’s fidelity would be too involved and too risky. We looked into 3D scanning and found a firm, Digital Surveys, who normally scan petrochemical plants and oil rigs and who specialise in “as built” surveys.
They worked with us to scan Winifred, a steam locomotive that had just returned from the USA in an almost identical condition to that she left the quarry in Wales in 1965. The survey, 3D model and 3D printed model that ensued showed us that we were on the right track...
...p.s. this data is too precious to lock it up, so we’re working on opening up the original data and the CAD files of individual parts with other manufacturers (of wheels and parts) and railway societies who are keeping the real things going!
How did we get here?
Thinkgeek’s $150 Bluetooth Communicators are based on 3D scans of a prop communicator; pair it with your phone and clip it to your belt: when you get a ring, the psychedelic hypno-disc in the middle will spin prettily, flick it open and start talking.
Harrison Young devised a miraculously cool “fiber-reinforced actuator” — a gripping robot-hand that can get traction on irregularly shaped, heavy objects, without any 3D printed parts and without any power-supply!
I first read George RR Martin’s 1982 vampire novel Fevre Dream as a young teenager, around the time I was also discovering Anne Rice and a host of other “contemporary” vampire novels who were reinventing the genre; now, decades later, I’ve been transported anew to the slavery-haunted riverboat where Joshua York and Abner Marsh tried to tame the ancient vampire before it was too late.
The realm of web development is constantly evolving. New platforms, languages, and processes materialize all the time, so staying on top of all that innovation is a tall order.Whether you’re brushing up on new tricks, starting from scratch, or just looking to make your own website a little jazzier, Rob Percival’s new Complete Web Developer Course 2.0 (now […]
Folks used to rely on alarms to protect their home – and before that, the family dog. Now, anyone looking to guard their homes can choose from some high-tech options, including the Amaryllo iCamPRO FHD Home Security Camera (now just $219 in the Boing Boing Store).In fact, this 2015 CES “Best of Innovation” award-winner boasts so many features, it’s […]
If you want a quality vaping experience, it’s usually going to cost you. Vaporizers that deliver a fast, controlled burn will set you back up to $300, which is why the FEZ Vaporizer (now just $99) is an absolute steal.The FEZ dry herb pen does everything that more expensive models handle at a reduced price. It heats up […]
