The IP Of The Infinite Build Volume 3D Printer

Last week, the Blackbelt 3D printer launched on Kickstarter. What makes the Blackbelt 3D printer different than any other 3D printer on Kickstarter? This printer has an infinite build volume. It’s built for continuous production. As long as you have a large enough spool of filament, this printer will keep producing plastic parts with no downtime in between. The Blackbelt is a truly remarkable and innovative machine. Yes, it’s a bit expensive, but it’s designed for production and manufacturing, not some guy tinkering in his garage.

However, the Blackbelt 3D website includes two words that have sent the 3D printer community into an uproar. ‘Patent Pending’ is something no one in the community wants to see given the history of the industry and a few poor decisions from the first movers during the great 3D printer awakening of 2010. The idea of an infinite build volume printer that allows for continuous production is not new; we saw one last March at the Midwest RepRap Festival. The question, therefore, is what is covered by the upcoming Blackbelt patents, what is the prior art, and is it still possible to build an Open Source printer that uses these innovative techniques?

Another Printer With An Infinite Build Volume

Very rarely do we see a 3D printer that is more than just a refinement of what’s currently standard practice. [Prusa]’s single-hotend, four-color printer makes the list, but that came out a while ago. The novel 32-bit controller board found in last year’s $200 Monoprice printer has the potential to change a cottage industry. Save those two exceptions, innovation in 3D printing really isn’t seeing the same gains we saw in 2010 or 2011.

A company out of the Netherlands, Blackbelt 3D, is bringing out the most innovative 3D printer we’ve seen since last March. It’s an infinite volume 3D printer that’s built for autonomous production. This printer can produce row after row of 3D printed parts, or it can print an object longer than the build plate. If you have enough time, filament, and electricity, there’s no reason you couldn’t print a plastic beam hundreds of meters long.

The specs on this printer are about what you would expect from a large machine meant for industry or prototyping, as opposed to a machine designed to print out tugboats and fidget spinners. The Blackbelt uses interchangeable print heads for the hotend with 0.4, 0.6 or 0.8 mm nozzles. The filament feed is a Bowden with the extruder hidden under the control panel. The frame is explicitly Bosch extrusion, and the machine’s build volume is 340 mm by 340 mm by whatever. Retail price (on Kickstarter) comes in at €9,500, but for an extra €3,000 you can also get a neat stand with casters on the bottom. Of course, with an infinite build volume, you could also print a stand. Continue reading “Another Printer With An Infinite Build Volume”
