What if a surgeon in an isolated northern Canadian town could manufacture custom-made surgical implants, right in the clinic, to allow reconstructive surgery to be done locally, rather than sending her patient hundreds of kilometres to a larger city? What if the owner of an electric bike in a rural African community could have replacement parts made, cheaply and quickly, in the nearest town with electricity? What if everyone with a great idea, and some basic computer skills, could click “Print” and have those ideas turned into physical realities? What if you didn’t have to drive anywhere to replace the plastic bolt that was missing when you opened the box for that Ikea desk, but instead just printed out out, yourself?
All of those things — life-improving things, big and small — are part of the promise of 3D printing.
If you somehow haven’t yet heard of 3D printing, now is the time. 3D printing is exactly what it sounds like — printing 3-dimensional objects much the way current desktop printers print 2-dimensional text and images. Although technologies vary, the most common method of 3D printing uses “molten polymer deposition,” basically laying down micro-thin layer after micro-thin layer of melted plastic to build things. Such printers operate much like standard desktop inkjet printers, but with an extra axis of motion and a “print” head that squirts molten plastic rather than ink.
To learn more about this technology, I paid a visit to Toronto’s own Panda Robotics, a startup in the final phases of finishing its prototype PandaBot printer. Unlike many existing 3D printers, which are aimed at industrial applications, the PandaBot is intended as a consumer gadget, priced at about $1000 and expected to ship in spring of 2013. The PandaBot plugs into a computer via standard USB cable.
I asked Pandabot co-founder Kelly John Rose why he thinks 3D printing is so exciting. “It opens up a whole new economy,” said Rose, “in customization for clients, in how designers can interact with their customers directly by creating designs and sending them cheaply over the internet to be printed out, and in how companies can provide better customer service by providing replacement parts at no cost to themselves.” In other words, to provide a replacement part, all a company needs to do is create a printable CAD file for the replacement part and make it accessible on its website. All the consumer has to do is download the file and hit “Print.”
It’s clear that the technology has significant implications for supply chains, and indeed for the way manufacturing is carried out. “As 3D printing continues to evolve at an incredibly rapid rate, it won’t be long before we will simply purchase designs and print them out as needed at home rather than go to a store every time we need a new part, new mug, or new tool,” Rose enthuses. “It essentially democratizes manufacturing.”
Entry-level 3D printers like the Pandabot are just the thin edge of the wedge, in terms of understanding the significance of this technology. Industrial-quality 3D printers are now being used for rapid prototyping and for architectural modelling. There are also reports that the US military has deployed one or more 3D printers to the front lines in Afghanistan, where engineers can use them to make replacement parts for vehicles and weapons right on the spot. Advanced 3D printers can print objects out of metals, too, so the possibilities are endless.
But cheaper, smaller-scale printers like the Pandabot are going to play a crucial role in weaving 3D printers into our lives, and into the way we think about manufacturing. According to Pandabot’s Rose, “the more 3D printers are out in people’s homes, the more companies will want to provide [printable] goods for them. The more companies provide goods for them, the more people will want these printers in their homes. It’s a positive feedback cycle that, once it starts, will change how we all purchase goods.”
Ethics isn’t just about rules. It’s about creating value, and seeking out better distributions of value. A focus on business ethics should include a focus on the ways in which markets and businesses create value, and the rules, principles, and innovations that help them do that.
