Hello. I'm trying to get into the 3D printing world recently, but I can't decide which technique is more suitable for beginners. Can you make a general comparison between options like FDM, SLA, and SLS? For example, which one makes more sense in terms of cost, complexity, print quality, and material availability? How would you approach this?
Which 3D printing technique is recommended for beginners?

FDM is absolutely the most logical choice for beginners. Why? First, the equipment and filament costs are much lower compared to other techniques — an entry-level printer can be had for around $200-$300, whereas a resin printer for SLA or powder systems for SLS can run over $1,000. As for raw materials, filaments like ABS and PLA are easy to find anywhere, while resins and powders require specialized suppliers.
The second part of the equation is complexity: FDM printers are simple to calibrate and maintain, and slicer settings (like Cura) are already optimized for newcomers. I’ve been modding phones since my Galaxy S3, and even on my first 3D printer, I had to deal with cables when changing filament — now it’s almost like playing with a tin toy. With SLA, on the other hand, resin spills, curing times under UV light, and post-processing (washing, curing) can be confusing at first. As for quality, with FDM you can reduce the "layer lines" effect by adjusting print speed, while resin gives you smoother surfaces but forces you to manually clean support material — which can be a hassle. In short, if you want to start without burning a hole in your wallet or your hands, go with FDM first, then move on to other techniques later.
