I've recently gotten into 3D printing but I'm not sure where to start. What are the differences between FDM, SLA, and other methods? What types of printing do people usually prefer? What do you base your choice on?
How does 3D printing start and what methods are there?

As a beginner in 3D printing, should I go for FDM or SLA in your opinion? I heard FDM prints are cheaper and more durable, while SLA offers more detailed results but the material is expensive.
Start with a budget-friendly FDM (Fused Deposition Modeling) printer like the Ender 3 or Prusa Mini—you’ll get the basics down without blowing your budget. I switched from ABS to PLA first (way easier to handle, smells better too), but if you need durability for functional parts, PETG is your best friend. Watched a ton of YouTube tutorials on bed leveling and slicing (Cura’s free and works fine), messed up my first ten prints before dialing in the settings. Calibration is key—start small, test cubes, then tweak layer height and temperature.
SLA (Stereolithography) is next-level for detail, like miniatures or precision prototypes, but those resin tanks and post-processing steps? Brutal for beginners. People rave about the Anycubic Photon for SLA, but man, the smell and clean-up feel like a science project. If you’re doing prototyping or small-batch production, SLS (Selective Laser Sintering) is cool, but those printers cost more than my first car—skip unless you’ve got cash to burn. My rule? FDM’s your workhorse, SLA’s for fancy, SLS is ‘maybe later.’ Also, join a local 3D printing group—trust me, you’ll learn way more from others’ fails than solo nights of tweaking settings.
Alright, so you're diving into 3D printing—welcome to the rabbit hole. First off, don’t get paralyzed by the options. FDM (Fused Deposition Modeling) is still the gateway drug for most people because it’s cheap, beginner-friendly, and the machines are everywhere. You’ll see Ender 3’s, Prusa i3’s, and all the clones dominating the entry-level space. The trade-off? Layer lines can be noticeable, and the prints aren’t always production-grade.
Now, if you’re thinking about precision or smooth finishes, SLA (Stereolithography) starts creeping into the conversation. Those UV-cured resin printers like Formlabs or Elegoo Saturn produce insane detail—think miniatures, dental models, or even jewelry prototypes. But holy smokes, the setup is messier, the resin’s toxic if you breathe it in, and post-processing (washing, curing) adds another step. Most hobbyists dabble in resin but stick with FDM for daily use.
And then there’s SLS (Selective Laser Sintering), MJF, and others—mostly enterprise territory unless you’re hacking a used industrial machine or paying absurd prices. If you’re asking what the *real* pros use? Most production teams in prototyping or low-volume manufacturing default to SLA or SLS for quality, but for raw versatility and cost per part, FDM wins in the wild.
Personally? If someone asked me for a recommendation today, I’d say start with a modern FDM printer (like a Prusa Mini+ or Bambu Lab A1) for the learning curve, then branch out to resin or even a desktop SLS (like the Nexa3D QLS) if your project demands it. Just don’t skip the basics—calibration, bed leveling, and material tuning matter way more than the machine’s brand. Oh, and budget for better filament too. Cheap PLA warps like a bad temper.
