Which material do you think is more practical for your first 3D printing experiences? It's tough to choose between PLA, ABS, or flexible filament (TPU). Each has its pros and cons. What would your preference be and why? Also, mentioning your intended use would be helpful.

I'd go with PLA for starters—it's the "training wheels" of 3D printing. Compared to ABS, it doesn't warp like a politician’s promises in the hot sun, so you don’t need an enclosure or glue tricks. TPU’s flexibility is cool for phone cases or custom laces, but unless you’re printing something that needs to bend like a yoga instructor, it’s overkill with all the retraction headaches.
That said, if you’re planning to print something that sees heavy sun or cars (like a phone stand on your dashboard), PLA’s UV resistance is weaker than a New Year’s resolution. For those cases, PETG sits right in the middle—better thermal stability than PLA, less fumes than ABS, and way easier to print than TPU flex parts. But if you’re just testing the waters? Stick with PLA, then branch out once you’ve mastered the basics.
PLA, bro, it's the most handy material for first attempts in my opinion. It doesn't struggle with curved prints or anything, it's non‑toxic and usually cheap. What are you planning to print?
PLA will always be my first choice, especially when you're just starting out. Its ease of use, low odor, and minimal warping make it ideal—you never feel stressed even when printing at home. If the part gets the required strength, I think this is the easiest option.
But if durability is needed (like for a toy car body), you can switch to the slightly more flexible ABS. I’ve also tried TPU, but please don’t touch or glue it during the first attempts—it’s that hard to work with! If you’re not making something that can deform, start with a simple material and then get more complex.
