financially worth it?

Probably not.

Did it give me brief respites of light against the clawing, ever encroaching abyssal darkness of life and misery?

Yes.

Buying a 3d printer and learning CAD is unlocking a super power. You can put something from your brain into the real world. It’s great for hyper specific parts.

The trick is to justify buying one for your business, and then using it yourself after hours.

As a business asset, it has paid for itself fivefold in less than a year. As an employee of said business, i have unlimited access to a machine that I could never personally justify the expense of.

Yes, I just finished printing a rudder core for my sailboat.

For all the headache its caused, its also saved me from several trips to the store to find cable ties, chip clips, a hair dryer holder, pencil cups, spice racks, etc.

Define “worth it”??

For many, it’s a hobby. For many more, it’s an adjunct to whatever hobby they do have. Hobby’s don’t have to save you money; and I’m militantly opposed to monetizing hobbies as a way to “justify” them.

Personally, I’m mostly 3d printing custom components (that I’ve designed), for R/C aircraft of various sorts. (Like, my cyclogyros, or the flying saucer powered by a 3d printed ducted fan; which is, more or less, a scaled model of the saucer from the OG Day The Earth Stood Still. or the thermal airship using toaster wire that has taken on a lot of different forms, ranging from 20’ star destroyers to whale sharks to a robot named Buoyant Bob that hands out candy on Halloween.)

I also enjoy 3d printing as a hobby, in of itself, too. (and spend waaayyyyy too much tinkering on the printer. its fun.) But it doesn’t have to save me money, and I feel no need to compare it to other forms of hobbies. It’s what I enjoy.

edit: lets put this in perspective. This would be like asking a golfer if they found golf worth it. the only real questions are “Do I enjoy it” and “can I afford it”. not “can it save me a buck”.

100%. I’ve printed some cool stuff and some stupid stuff, as well as a bunch of functional parts that have improved my life around my house. More importantly it’s given me a huge creative outlet to get more and more outlandish with my CAD designs and push my experience limits, which is great because that helps me be a lot more efficient at work.

Financially it was a total waste of money but that doesn’t matter when it’s a hobby. A hobby with practical marketable skills, and also the ability to let me prototype some independent ideas I’ve been brewing for a while to maybe sell for some side cash…

My first 3d printer was a xmas gift from my partner and its been a blast to tinker with, I have found it useful for printing parts, toys, parts, all sorts of stuff. I purchased a much larger one so I can do larger and faster prints, and while I think the build has been worth it, I would NOT recommend buying the FYSETC kit I did.
