It burns money and can be fun or frustrating. I see it as a university course. You could spend the same amount on a book for that course. Your “return on investment” is not immediate.
You'll learn A LOT, and who knows? It might be useful to get a job one day. I have a somewhat controversial opinion. Now this only concerns the national impression. If you are not going to design your own things, if you are not a creator, then no, a 3D printer is not a good buy.
Printing dice is a great idea if you want to print loaded dice, anything with less than 80% fill, or something like that, and the dice aren't random. Having your own printer also gives you more flexibility to play with the settings. If you're using someone else's printer, simply give them the STL file and tell them to print this, with perhaps the option of giving them some instructions on how you want it to print. However, you're not going to be able to observe the process and actually adjust the settings for the best results.
You are the only one who knows what your piece is supposed to do and you know the best approach to printing it. There are certain people who ask me questions like: can you print something for me for this part of my car and I say no because I can't just print it?. I have to map it, draft it, design it, modify it, THEN print it, then verify its success through quality control or adjustment. If you're not ready to do those things for your project, then 3D printing isn't for you, unless you want to print knickknacks and knickknacks with thingiverse.
Within 2 weeks of spending $17.50 on a printer, I got a job that cost me $1700 and I've already done a lot of things that have saved me hundreds of dollars in my wood shop. Obviously, not everyone's experience will match mine, but it may be worth it. Considering that I have a list of 300+ monsters and dozens of accessories to choose from, I'll quickly pass up the cost of buying them for themselves. However, if I weren't a DM, a printer wouldn't be worth it for me.
Right now, for me, it's about exploring technology and doing the things I want or things that I've always wanted but that were never available for one reason or another. Our advice? If you want to dedicate yourself to 3D printing as a hobby, then don't go into it expecting that you will eventually make money with it. Like other hobbies, 3D printing can turn into a black hole for your time and expenses. Still, it's worth it if 3D printing gives you the satisfaction of exercising your creative muscles and learning something new.
Before you decide to buy a 3D printer, consider whether the person you're buying it for has enough space for them. This is the only way to produce jewelry, tools, tripods, gifts and novelty items, as well as toys with 3D printers. As with other hobbies that are eventually forgotten, there are probably millions of desktop 3D printers around the world that have barely been used. For more entrepreneurial users, 3D printing can be offered as a service or used to create customized commercial products.
You'll start adding and updating your printer quickly, so be prepared to spend a good amount of money and time. Since 3D printing has many learning curves, DIY kits will help you develop a solid understanding of technology. Printing dice is a great idea if you want to print loaded dice, anything with less than 80% fill or something like that, and the dice aren't random. Even if you can't fully devote yourself to 3D printing or modeling as a hobby, you can make good use of your 3D printer to support your other hobbies.
In terms of creative freedom, there's probably no commercial technology that can compete with 3D printing. Between having a stock of filament spools and making sure the 3D printer has enough ventilation, you will almost certainly need a large space for this simple hobby. Buying other people's parts may be a good option, but having your own 3D printer gives you more flexibility. One of the biggest advantages of 3D printing versatility is that it can be perfectly adapted to other hobbies.
