It’s taken years to perfect them, but desktop 3D printers that uses a conveyor belt instead of a traditional build plate to provide a theoretically infinite build volume are now finally on the market. Unfortunately, they command a considerable premium. Even the offering from Creality, a company known best for their budget printers, costs $1,000 USD.
But if you’re willing to put in the effort, [Adam Fasnacht] thinks he might have the solution. His open source modification for the Ender 3 Pro turns the affordable printer into a angular workhorse. We wouldn’t necessarily call it cheap; in addition to the printer’s base price of $240 you’ll need to source $200 to $300 of components, plus the cost of the plastic to print out the 24 components necessary to complete the conversion. But it’s still pretty competitive with what’s on the market. Continue reading “Infinite Axis Printing On The Ender 3”
Infinite-bed 3D printers have long been an object of desire in our community, but it has taken a long time for the promise to catch up with the reality in terms of relatively affordable models that live up to expectations. They’re still a little expensive compared to their fixed-bed cousins though, so if you hanker for a Creality CR30 but only have the cash for an Ender 3, [Michael Sgroi] may have the project for you. He’s created the EnderLoop, a set of parts to perform the conversion from a stock Ender 3 to a fully-functional belt printer.
It takes the Ender 3 gantry and tilts it sideways on a pair of 3D printed supports, and replaces the stock Y azis with a belt on rollers driven by a larger motor through a timing belt drive. He has a variety of suggestions for sourcing a belt, and in his case he’s chosen one from PowerBelt3D. As well as the GitHub repository already linked, it can also be found on Thingiverse.
It’s clear that hacking apart a reliable printer in this way is not for the faint-hearted, and that a cautious hacker might prefer to wait a while for a cheaper off-the-shelf model. But we can see that the reliability of the Ender 3 will mean that its parts are still of decent quality in the new configuration, and that it looks as though the base printer can be reassembled should a belt-based build be a failure. Infinite bed printers will inevitably have a major presence in our community, and it is designs such as this one which will lead the way as they evolve into reliable machines.
