3D Printer FYIStart with one part and one room. “Which is better, FDM or resin?” hides both.
This page is a process decision. It is not a printer ranking and it does not include a chooser. The FDM buying guide and the resin workflow guide stay the longer references.
Write the job in ordinary units
Record the largest dimension that must print in one piece, the smallest feature that has to remain readable, whether the part will be handled or painted, and whether the room has a sink, ventilation, and a place to keep uncured resin closed.
A 180 mm indoor cable bracket and a 28 mm tabletop miniature are different jobs. They can share a workshop. They should not share a default process.
What each process is answering
Fused-filament machines stack a thermoplastic bead. Family guides such as Prusa’s PLA note describe easy printing and limited thermal or mechanical demand; they do not certify every brand. PLA
Masked resin machines harden a photopolymer layer against a film. Handling, washing, curing, and disposal are part of the process. Formlabs documents disposal as a first-class step, not an afterthought. Disposing of resin
Neither summary is a strength contest. One process asks more of the slicer and the nozzle. The other asks more of the room after the print finishes.
Two worked decisions
Desk cable bracket. The bracket sits indoors, away from warm equipment, and only has to hold a measured cable. Filament is the process to investigate first: the geometry is large relative to a miniature, the finish can be coarse, and you can iterate without wash and cure. Open the printer catalog if you still need a machine, or the material guide if you already own one.
Painted 28 mm miniature. The faces, shields, and undercuts are the product. Resin is the process to investigate first, provided the room can isolate liquid resin, isopropanol or a wash station, and a cure light. The resin guide is the workflow, not a shopping list.
If both jobs matter this month, you are buying two processes or you are splitting the work. A filament printer will not become a resin printer because a listing used the word “detail.”
What this page will not do
It will not convert a resin convenience feature into an FDM recommendation. It will not invent a universal cost per millilitre or per gram. It will not tell you that one process is cleaner; resin handling is a workspace control problem, and filament still produces particles and heat.
When the process is chosen, use the selector only for machines that match that process.
