PLA vs Resin
This is really a choice between two technologies. PLA is an FDM filament — cheap, easy, strong enough for most uses, good for larger parts, and clean to handle. Resin (SLA/MSLA) produces dramatically finer detail and glass-smooth surfaces, making it the choice for miniatures and jewelry — but cured resin is brittle, the workflow is messy, and uncured resin is toxic and needs gloves and ventilation. Choose by the job: functional or large or beginner-friendly means PLA; tiny, highly detailed display pieces mean resin.

Which should you choose?
Choose PLA for functional parts, larger models, prototypes, and a clean, low-hassle workflow — PLA is cheaper per part, far easier, non-toxic, and strong enough for most real uses.
Choose Standard Resin for miniatures, tabletop figures, jewelry masters, and detailed display models where surface quality is everything — and you're set up to handle resin safely with gloves, ventilation, and proper disposal.
