I've been considering a 3D printer for quite some time. Do you recommend FDM or SLA?
What kind of things do you print? How often do you use it? Does it just collect dust? What kind of hobbies do you have and does a 3D printer support/enhance it?
After having both if you don't mind mess; SLA
I second SLA. Especially if you just want to print small things that look really good.
I went back and forth and have both, but ultimately I’ve ended up enjoying FDM a lot more. It really depends on both what you want to accomplish, and how much you’re willing to spend.
I started off with a cheap Ender 3 V2, used it for a little while, then stopped using it as it was a nightmare having to level it and calibrate it constantly. After that I got an Elegoo Mars 2 Pro as I wanted to be able to make prints without all the mechanical complexity of a FDM printer. It was nice for a while, but I ended up not using it as much because I realized that I enjoyed making functional parts a lot more than art/display pieces like miniatures.
I ended up biting the bullet and getting the best printer I knew of at the time: the Prusa i3 MK3S+. I got the kit version so that I could save some money. While I wouldn’t get another kit, I do think that everyone should get a printer that they need to build from scratch at least once. I learned about every single piece of the machine in detail as I went along, and I now clearly understand what people mean when they use terms like “gantry”, “idler”, “heat break”, etc.
After assembly, the MK3S+ was effortless to use in comparison to the Ender 3. It completely changed my mind in regards to what FDM printers could be. I was even able to get some incredibly detailed sculptures out of it (though, of course, not at the level of a resin printer, but still). This printer has been my main workhorse ever since, and I’ve been using it basically nonstop for all kinds of different projects. It’s even paid for itself with a side business I’ve been running by selling parts to people on FB Marketplace.
Overall, I’d personally advocate for FDM. It is far more versatile than resin in terms of print durability, functionality, cleanliness, and size. It’s even cooler if you get into some light CAD design for making your own parts. Even if you want to make detailed models with it, you can always just swap to a smaller 0.2mm nozzle, print at a lower layer height, and get very detailed prints.
I am into woodworking, custom keyboards, gaming, and a whole host of other hobbies (including 3d printing, haha) FDM is definitely the most useful for my personal hobbies, though I have been interested in Warhammer 40K lately, so maybe a new resin printer is on the horizon for me, who knows.
Ultimately, it’s up to you to decide, but if I had to suggest a good start, I’d go with FDM unless you really want to make minis.
