I just feel like I see too many trying to make the printer be the end-all, be-all thing maker, when that’s a sub-par use of the technology. I’ve seen assemblies with the friggin’ WASHERS 3D printed. There IS something of an actual issue with a lot of these channels trying to print every single piece of something, and it’s obvious that, a lot of the time, it’s not for the challenge of doing so. It was a jab at the OP implying that 3D printing is somehow comparable in expense and difficulty to machine work because you “need” to know CAD, as if modern machining and design work in general doesn’t benefit heavily from the same.Īnd, no, I’m not ego stroking by criticizing something. That part wasn’t a jab at the guy making the pump. Posted in 3d Printer hacks Tagged PLA, pump, water pump Post navigation We’ve seen 3D printed pumps put to real work before, too, like this fertilizer dispenser. Instead, all the hard work is done on the CAD side of things. It’s a great example of how 3D printing can allow the creation of machines with complex geometry without the need for advanced machining skills. The design is on Onshape, for the curious. Turned with a drill at 1800 rpm, the pump is able to achieve a flow rate of 13 litres per minute, or a maximum head of 1.2 meters.

Notably, no shaft seal is included, so the pump does leak a bit, but it’s not a major concern assuming you’re just pumping water and don’t mind spilling a bit of excess. There are a few ball bearings inside to allow the impeller to spin nicely, too, with hex head fasteners used to hold everything together and a long bolt used as the main impeller shaft. Gaskets are printed in pliable TPU to help seal the housings. The pump’s housings and impeller are all 3D printed in PLA, as well as the inlet which is designed for a 2L soda bottle to screw into. A great example is this centrifugal water pump that can really deliver the juice, courtesy of. Once upon a time, 3D printing was about churning out tiny Yodas and Pikachus, but these days, useful things are regularly 3D printed too.
