Aurora Tech is Aurora’s and Helios Lung’s sister team. The two go into 3D printing and take their time to lay out all of the nuances. Aurora will usually be in front of the camera, while Helios will be behind the scenes planning, testing, and editing.
In this case, they pitted the Creality Ender 3 S1 Pro vs Prusa MK3S, two industry titans. These two are among the most well-known, and rightfully so. I understand how difficult it is to pick between them because they offer tremendous value. This has to be one of the most often asked questions I see on the internet.
I’ll throw in a personal tale here. Still, full disclosure: Prusa hosts a Maker Faire and has previously sponsored events here: I own both systems. I use both regularly. I got more consistent results with the Prusa out of the box for print-in-place items and exact objects that need to fit together. It has lasted longer than the others. However, because the Ender is less expensive, I’ve recommended it to several folks who want to get their feet wet in the pastime.
