IIHTM: The Digital Workshop

If I had the money, what would the dream workshop look like?

I'm a computer tech teacher by day, and the 3d printer revolution is astonishing to behold.  The dream workshop would have the usual suspects (awesome tools etc), but it would also have some truly alien looking tech.

Ever seen a resin based 3d printer?  It's like something out of Terminator:



3d printing is about to get even wilder, with larger scale prints becoming an option.  Imagine a 3d printer that could handle motorcycle fairings... except you could do anything you want.  Want a fairing made out of dragon scales?  No problem!  Want customized etching across the entire fairing?  No problem!  Want to design a radical fairing using the stock mounting points?

Some time in Blender and you'll be ready to print radically customized fairings and other parts.



The BigRep1 goes for almost $40,000, but imagine what you could print in over a cubic meter of build space - motorcycle fairings would be not problem.  I think I'd rent one first to see what I could get away with before buying.

Using resin based printing instead of additive 3d printing means you can produce parts that have the same structural nature as cast pieces (they aren't made of bonded parts).  These pieces would be incredibly strong - they could also be made much more quickly.  Instead of hours long build times, we'd be looking at minutes...



If you're looking for futuristic workshop inspiration the Big Hero 6 garage would be a good place to start - in there he's 3d printing carbon fibre!  The holographic display is pretty dope too...



Iron Man is another film that gives you a good idea of what a 21st Century garage might look like.  Tony Stark's workshop is a holographic wonderland with built-in fabrication capabilities.



It was once thought that with fuel injection, onboard computers and digitization we would be losing the ability to modify and customize our motorbikes.  It turns out that digitization is actually handing the ability to manufacture back to individuals from the factories that took it from them.  Industrialization meant standardization and centralization in the 19th and 20th Centuries.  In the 21st Century manufacturing will return to the craftsmen it started with; localized micro-manufacturing is going to be the way of things to come.

If you're making shop space for yourself, having a computer in it gives you access to a world of information (I frequently use my to watch how-to videos and view schematics), but that workshop based computer is soon going to be providing a lot more than just information.  Do yourself a favour, get a handle on 3d modelling, it'll come in handy in the near future.

Ways to get started:
  • Get handy with Blender - it's free, and it's powerful!  There are also a lot of tutorials available for it online
  • Structure Sensor: a 3d scanner that snaps onto your ipad.  It makes making 3d copies a breeze!
  • Basic 3d printers start at about $1000.
  • If you want to give printing a try, many people in the maker movement offer 3d print services. It's a nice way to see what a 3d printer can do for you without the overhead... 3D Hubs is one such option, and they'll introduce you to makerspaces in your area.
  • Sketchfab is handy for sharing and doing light editing on 3d models.







Update:  Just saw this.  It'll print 18 x 18 x 24 inch pieces and is made by a Canadian company!  That'd do the business...

Are you ready for your fitting? Tailored Motorbikes & Micro-manufacturing...


I just read a good article in Motorcycle Mojo called, "Building The Perfect Bike."  In the article the author supposed that since no 'off the rack' bike fits properly, he would give himself a new bike budget, buy a lightly used machine and create a custom-fit.  His exercise made for an interesting process, and he got closer to a custom fit, but it's still far from a tailored motorbike.
Cycle-Ergo lets you quickly
assess a bike's fit, and allows
for modifications to control
locations.

I've used Cycle Ergo to great effect when considering off-the-rack bikes for fit, but you have to wonder how long it will be before we migrate from mass-produced, generic machines to personalized/tailored ones.  In that future Cycle Ergo two point oh will 3d scan you and get your performance needs and produce a custom machine specifically for you.

My day job is as head of technology at our local high school.  My focus there is in information technology and electronics.  I work closely with our technology design teacher who has a background in robotics.  We've both watched the rise of specialized manufacturing with great interest.  Our labs have taken on 3d printers, digital routers and five axis digital CnC machines in response to this evolution in manufacturing.  The prices on these devices have dropped dramatically over the past few years.  It won't be far off when you'll be able to custom build parts from scratch for a fraction of what it used to cost.

Computer controlled, small scale manufacturing will radically change our understanding of what have always been industrial scale production processes.  I suspect that in the future most of the manufacturing process will decentralize from factories and into regional shops that can produce customization on a scale unimaginable to 20th Century industrialists.

Some of the very high end motorcycle manufacturers are already embracing the idea of tailoring a machine to the rider.  Even a tiny volume manufacturer like Brough Superior can now consider machining all its own pieces in response to individual customer demand.  As the costs of personalized machining come down, the idea of a tailored motorbike will become the standard rather than the exception.

When you can cut your own pieces,
you can build your imagination.
One of the unseen hands that is encouraging the latest surge in the customized motorcycle scene is access to machining and manufacturing processes that used to only make sense in thousand plus unit runs.  You can build an astonishingly well built customized machine nowadays because you can build the bits you need for it to your own specifications.  Custom builders are a step toward truly individualized production.

Rather than plugging my dimensions into a database of bikes, one day soon I'll be plugging my dimensions and performance needs into a blank template and watching the perfect bike form around me.  The seat would be designed for my backside, the handlebar grips built to fit my hands.  The system would then CAD/CAM out all the parts and custom produce everything from the frame to engine components, all to my specific needs.  The distinction between OEM and aftermarket will disappear, there will only be builders.

Now *that* would be a perfectly tailored bike!
