A revolution in the making — printed out in 3D

Additive manufacturing, robotics, nanotubes ... the new industrial revolution is here. But will it all really transform lives? In a new Crikey series, we begin in the world of 3D printing.

Round the broad display windows in Boston’s Back Bay, a small crowd has gathered. In the window, from the teeth of a machine, a dragon is emerging. Rainbow-coloured, in bright plastic, feet first, tail bucking behind, the figure is classic Dungeons and Dragons, framed by a black and silver machine, with the word “Makerbot” blazoned across the front.

    Love it. I’ve had some exposure to 3d printing due to my studies, and it’s still amazing the sort of details stereolithography can create (internal staircases on non-solid chess pieces – beautiful to see) as well as how far it’s advanced in the 8 years since I last was involved.

    Looking forward to the next in this series.

    I don’t even have an ordinary printer. I used to have one, but I eventually got rid of it, because I’d print a page or two, and then 6 months later, when I wanted to print something else (I rarely need to take hard copies of anything), the ink cartridges had dried out (or the ink had evaporated or something) and I had to replace them.

    There’s something wrong when the cost of replacement cartridges is greater than the price of a new printer.

    Nowadays, I just put a .pdf copy on a thumb drive and take it down to the local newsagent to print in their photocopier. 20 cents a page is a bargain.

    Brilliant stuff Guy and well done Crikey. By far the most important story in today’s edition and you’ve put it first.

    A most interesting topic, I’m looking forward to the elaboration.

    At the moment it appears to be merely an alternative method of producing more [email protected] we don’t need.

    I must admit to being somewhat resistant to the enthusiastic hype that often accompanies new technologies. But I find that a concept from Gartner called “the Hype cycle” is a reminder that sometimes technologies do mature into something that is actually useful, and perhaps even widely used. Given time.

    @zut alors, some may argue that this technology could ensure we produce “less crap we don’t need”, as the demand, supply chain, manufacturing process, is all on-demand on an end user needs basis.

    Imagine for example that you accidentally bust the hinge on the toilet seat. Now you could go to Bunnings and buy a whole new toilet seat set manufactured in China, or else you could just knock up the 3D part from home providing you paid for the rights to use the 3D part definition from the designer.

    Now which is more wasteful?

    It will be an incredible change to the way we procure goods, looking forward to it.

    Yes, a factory can pump out the equivalent part for a lot less, however the markups through the supply chain are enormous. I used to work at a metal turning shop, what we manufactured and sold for a $1 to the client was eventually sold at retail for $25 at Kmart – eek!

    Great stuff – a good mate of mine is a fitter/turner who currently works at a private school teaching kiddies the basics of metal/production/prototyping etc, and is involved with their “Pedal-Prix” vehicle that they compete with. They have aquired a small 3D printer and, to cut a long story short, they have manufactured may small pieces of their racer with this machine.

    Recently we were involved in a 6hr scooter race and one of the fire breathing steeds (eh?) we prepared for this event (you have to try this, it is too much fun) was fettled using parts produced with the 3D printer. As mentioned in GR’s article the texture of the finished product was rough, but with apropriate sanding and finishing each part fitted perfectly and performed flawlessly. And they were designed and produced by people who don’t possess software/hardware engineering backgrounds.

    I am waiting in eager anticipation for the next installment of this series, GR.

    I went onto one of the 3D Printing sites mentioned in this article and spent a good 2 hours browsing. As someone who can use 3D CAD I’m inspired.
    I can’t see people owning individual printers but printshops where people go in and load up something from a USB are a real possibility.
    The real interesting phenomenon will be how individuals use these printers to be creative. I would also start divesting any shares I have in the plastic toy industry as these printers could really make producing children’s toys a much more democratic process. I’m thinking of Girls toys in particular which are pretty nauseating at the moment.

    Much of the manufacturing which has shifted to developing countries could move back again closer to the point of use.
