Additive manufacturing (or 3D printing) may finally have its moment. The technology has been around for decades, but only recently has it managed to crawl out from behind the curtains of advanced industrial production and bearded basement hobbyists into the awareness of the general public.
This year saw 3D printing get a nationally-televised shout-out in the State of the Union as well as the launch of the Inside 3D Printing conference and expo in New York City, the first business and consumer conference specifically built around this budding industry.
While some analysts have made predictions that 3D printers may dip below $2000 by 2016, the Inside 3D Printing conference featured models that are currently available for less than $1000, even. (One such model has been around for a year.) 3D printing may be on its way to becoming a desktop staple.
3D Printers: The desktop scanner of the coming decade
One of the conference's keynote speakers, industry consultant Terry Wohlers, used his stage time to explain why he is very bullish on the technology's future, noting that in 2011 (the last year for which reliable data is available), the industry grew by an impressive 29.4 percent.
Wohlers estimates that there are 2.9 million industrial designs for printed parts currently being used by a few high-end manufacturers. But that number pales compared to the 12 million consumer-printable designs available on sites like Thingiverse, which offers a bevy of downloadable designs submitted by the public. Of course, most of these millions of designs are being created and shared by a small population of dedicated hobbyists.
But this may start to change in the very near future.
As you'll see below, the prices of several consumer models of 3D printers are comparable to those of high-end computers. While the average person will have little need for a 3D printer--for now, they are limited in the materials they can employ, and they can take hours to print an object the size of a chess piece--certain specialized professions will find lots of uses for them.
In the very near future, a desktop 3D printer may be greeted in the same way the desktop scanner was in our recent technological past: It's not a piece of technology that all consumers will use, but it is something few would find out of place on someone else's desk.
Here are a number of consumer 3D printers coming your way:
The Form 1 ($3300)
For the high-end designer, artist, or architect, Formlabs' Form 1 stereolithograph printer offers a $3300 desktop unit. This is an impressively high-resolution model that can render details down to 25 microns (or 0.001 inches).
