Resin or FDM Printer? How to Choose in 2026

By the Daniel Bohannon team · 2026-07-17

Resin and FDM printers cost about the same these days — both picks below land in the $200–300 range — but they're completely different machines that happen to share a hobby. FDM melts plastic filament and draws your part one layer at a time; it's the workhorse for brackets, enclosures, toys, and anything that needs to survive being used. Resin (MSLA) cures liquid photopolymer with UV light, and it resolves detail FDM simply can't touch: crisp faces on a tabletop miniature, clean raised text, jewelry-grade surfaces. The price of that detail is a chemical workflow — gloves, ventilation, washing, curing — that never fully goes away.

So the question isn't which technology is better. It's which output you actually want, and how much mess you're willing to live with.

The picks

The A1 Mini is the FDM pick because it removes the part of FDM that used to scare beginners off: calibration and constant fiddling. Auto-everything setup, excellent quality on stock settings, and a slicer that behaves. It's quiet enough to share a room with, and the optional AMS lite adds four-color printing — with the honest caveat that color changes burn filament on purge waste. The trade-offs are the small 180mm build volume and an ecosystem that's more closed than Creality's. Judging by its 4.7 rating, most buyers decide they don't care.

The Mars 5 Ultra is the detail machine. Fast exposure times off a mono LCD, easy leveling, and built-in AI camera monitoring that watches for failures — genuinely useful on a printer you don't want to hover over. If you print tabletop minis, chess pieces, jewelry masters, or display models, this class of printer is the correct answer and FDM is not. Budget for a wash-and-cure station too; it's effectively part of the purchase, not an accessory.

How to actually decide

Answer two questions. First: what will most of your prints be? Functional parts, replacement bits, props, larger objects — FDM. Miniatures, detailed display pieces, small precise models — resin. There's no clever middle answer; the technologies really are that different.

Second: where will the printer live? An FDM machine can sit on a desk in a bedroom. A resin printer shouldn't. Uncured resin is a skin irritant, the fumes want real ventilation, and every single print ends with a wash in alcohol and a UV cure. In a garage or a ventilated workroom, that's a ten-minute routine you'll stop noticing. In a small apartment with no airflow, it's a dealbreaker — better to admit that now than after the machine arrives.

Who should skip which

Skip the Mars 5 Ultra if you have no dedicated, ventilated spot for it, if small kids or pets can reach the workspace, or if post-processing sounds like a chore rather than part of the craft. Resin printers bought on impulse end up in closets.

Skip the A1 Mini if miniatures are your entire reason for buying — FDM layer lines at tabletop scale will disappoint you no matter how well tuned the machine is — or if you regularly need parts bigger than its small plate allows.

Bottom line

First printer, not sure what you'll make: get the A1 Mini. It's the one you'll actually use every week. Buying specifically for minis or fine detail, with a ventilated place to put it: get the Mars 5 Ultra and order the wash station at the same time. Plenty of people eventually own both — but usually only after the first machine taught them which kind of maker they are.
