TangiBot and the perils of Open Source Hardware

TangiBot and the perils of Open Source Hardware:

I’ve commented before on the terrible inefficiency and artificially high expense of the current crop of 3D printers. It simply doesn’t make sense to produce the plastic parts of 3D printer kits on a printer farm when there are literally thousands of Chinese injection molding companies that will make those parts cheaper. It looks like [Matt Strong] heeded my call and now has a Makerbot Replicator clone up on Kickstarter that costs $700 less than the official version. We assume the Makerbot lawyers are having a busy morning.

From the info on the Kickstarter page, [Matt] is used parts from his Makerbot Replicator to design a one-to-one copy. Every part and component on [Matt]‘s TangiBot is 100% compatible – and seemingly 100% identical – with the Makerbot Replicator. Like the Replicator, [Matt] is offering a dual extruder version that allows you to print in two colors.
At the bottom of the Kickstarter page, under a section titled, “How is 3DTangible able to make a Replicator Clone?,” you’ll see [Matt]‘s reasoning for cloning the MakerBot replicator. He says everything is open source, and, “MakerBot used other open source designs when designing and producing their 3D Printers.” We’ll agree that MakerBot used existing extruder designs (and improved upon them), but MakerBot was not this blatant in borrowing from the RepRap project.
For want of editorializing, I’ve complained about the stupid inefficiency of manufacturing 3D printers with 3D printers before. It was only a matter of time before someone realized current manufacturing techniques can be used to make 3D printers cheaper. [Matt] – dude – you were supposed to clone a RepRap. Makerbot has done some really incredible things for the community such as building Thingiverse and generally being an awesome cheerleader for the 3D printing community. Taking the flagship Makerbot printer and making it cheaper will not make [Matt] any friends on the Internet, but at least the laws of economics are coming to the world of 3D printers.
Thanks [Brad] for sending this in.
