Bridges are a part of our constructed landscape that we take for granted. And bridges by themselves aren’t especially important. What is important is that bridges let you get from one place to another. Technology is often the same. We get from point A to point B through some bridge technology that, probably, most normal people never even notice.
Years ago, point A was commercial 3D printing. Industry had stereolithography, selective laser sintering, fused deposition modeling, and other rapid-prototyping technologies. These were not toys. They were expensive industrial systems used by companies that needed prototypes badly enough to pay serious money for them.
Fast Forward to Today
Today, you can go to a big box store and buy a 3D printer for well under $1,000, and often far less. Modern machines are almost plug-and-play and tend to do all the hard parts for you. That’s point B. How we got between points is a story of hackers who had a dream, and many Hackaday readers lived through it and even played a part in that bridging.
For a long time, RepRap was synonymous with hobby-level 3D printing. The project, started by [Adrian Bowyer] at the University of Bath in 2005, was built around a powerful idea: a machine that could print many of its own parts, thereby helping make more machines. RepRap Darwin reached its early self-replicating milestones in 2008, and the movement produced a thicket of descendants, variants, and arguments about rods, belts, bearings, extruders, firmware, and what “self-replicating” really meant. Of course, the machine could only print some of the parts you needed, but it was still impressive how much of a printer you could make with one printer.
Without RepRap, the desktop 3D printer boom would have looked very different. It created a common pool of ideas: Cartesian frames, printed brackets, hobbed bolts, heated beds, RAMPS boards, Marlin firmware, and a whole common vocabulary. It also created the expectation that a 3D printer was something you could understand, modify, repair, and improve. That expectation would not survive everywhere, but it defined the early culture.
Kicking Kickstarter
By the early 2010s, 3D printing had the right ingredients for a crowdfunding explosion. The technology was visible enough to be exciting, but not yet mature enough to be boring or attract big players. Hackerspaces were multiplying. Arduino had made embedded tinkering feel approachable. Laser-cut plywood, stepper drivers, and commodity motion hardware were easy to source. There were enough RepRap veterans to know what worked, and enough newcomers to believe the next machine would finally make 3D printing simple.
Kickstarter was a perfect amplifier. A desktop 3D printer looked good in a campaign video. It moved. It made things. It appeared to turn imagination directly into plastic. Printrbot was one of the defining examples. [Brook Drumm’s] original Printrbot campaign launched in 2011 and became one of the notable early 3D p
