If you’re using the space for other things and paying dues already, then it may be worth it, but if its a long drive you’re either gonna have to drive it a lot or spend time waiting at the space to make sure your prints are doing good. In the end its up to you, some people like classes cause they give you all the information you need to get started in a nice and condensed format, and others like to spend some time figuring it out themselves through youtube/reddit.
When I was a student at UT I opted for just getting my own Ender 3 for $~200 because I got annoyed waiting for the ones at our makerspace and constantly going there and back (well, it was even less convenient there because we were supposed to be present in the space constantly while our print was going). It’s still going strong 4 years later, and I’ve learned a lot by troubleshooting it and upgrading slowly.
