I’m pretty sure I can stand on it without issues, if I add some corner plates it would be even stronger.
But when it doubt you can always go for 3030 or 4040 which would be really strong, you can probably park a motorcycle on those

How stable is this rack. Would that be a good frame for building a 3d printer table?

My old FDM printer frame and I think most are made of extruded aluminium exactly like this. Extremely sturdy and can be adjusted very finely with machine screws

I have an FDM printer (Ender 3 clone) that is mostly 2020 aluminum extrusion as the frame. A few years ago I found some 2020 on sale and built a set of shelves for my wife’s plants out of it. (Now - I know. It’s not the most economical use of materials, but it was the middle of winter, and I didn’t want to go work in the garage. Plus the 2020 was on sale.) It’ll support a slew of plants over a 4-foot span (~3.2m) without any sagging or other concerns. It can be wobbly side to side, but that’s a matter of bracing and connectors.

1.2m.

I know. I was just seeing if you would notice. awkward laughter
(But thanks, I was trying to wing the conversion and started off with 3.3ft =1m and then did the numbers meme while my fingers typed gibberish.)

Extruded aluminum of that type is insanely stable and easy enough to build for a reasonably handy person.
You only need a cheap cutoff saw and a drill, or you can order pre-cut and ore-drilled pieces to order.
There are a number of makers of extruded aluminum building systems, basically tinkertoys for adults. I have personal experience using 80/20 and the Tslots brands. They are functionally identical.
I have used it to build stands for heavy equipment like ultra-cold freezers for labs. It is more than sufficient for any server racking.
