Editorial Review

Assembling the Kossel XL Delta 3D printer is not an exercise for the faint-hearted. Born of the Reprap project, this beast of a kit can be a struggle to get up and running. But — assuming it’s put together correctly and calibrated accurately — it’s one of the best value-for-money options available for under $400. Capable of print resolution as fine as 50 microns, the Kossel XL’s oft-cited print speed of 320 millimeters-per-second far outstrips most Cartesian printers.

Delta 3D printers, as opposed to their Cartesian cousins, are a polarizing subject in the desktop manufacturing universe. While Deltas print with a certain grace and fluidity, they are known to be quite sensitive to any disturbance, and require frequent calibration — calibration which, due to the connected nature of all 3 axes, can be quite difficult. They are also extremely accurate printers when constructed correctly, and the Kossel build is certainly up to that standard.

The Kossel design was conceived in 2012 by Reprap member Johann. It’s named after Ludwig Karl Martin Leonhard Albrecht Kossel, a German biochemist who first identified the nucleobases that make up DNA — a lofty standard to live up to. Thanks largely to the Reprap community, the Kossel makes one hell of an effort to live up to its namesake.

The speed boost and print quality of the Kossel XL and other delta printers make these outliers of the 3D printing world well worth a look. Less advanced tinkerers who choose to take the leap, though, might want to study up on the sometimes fickle speed demons first.

I've bought this Kossel XL from AliExpress. Took me a while to assemble the kit and configure. But everything is working perfectly fine.

Best printer I had now. Before was Prusa 3 and Mendel. The Kossel XL is faster, better, cheaper and much bigger.

Unfortunately, there were several major issues... Once they have some of these quality issues worked out, I would be able to recommend their product, but not until they do.
