Should I buy a resin or a filament printer?
Short answer
Resin for small detailed things — miniatures, jewellery, dental models. Filament for anything functional, large or that needs to be tough. Resin's detail advantage is real; so is its handling burden.
The resolution difference is not subtle
A filament printer draws with a nozzle typically 0.4 mm across. A resin printer cures a pixel measured in microns — the machines here range from about 14 to 46 µm. That is an order of magnitude, and it shows: faces, fabric folds and fine surface texture that a filament printer approximates, a resin printer simply reproduces. If detail at small scale is the reason you are buying, the decision is already made.
The workflow difference is not subtle either
A finished filament print comes off the plate ready to use. A finished resin print is covered in uncured photopolymer, which is a skin sensitiser. It has to be washed in isopropyl alcohol, then cured under UV, then have supports removed, and the contaminated alcohol has to be dealt with. Gloves and ventilation are baseline requirements, not precautions for the cautious. Budget for a wash station, a cure station, alcohol, gloves and a disposal plan on top of the printer.
Material properties differ too
Standard resin parts are harder and more brittle than filament parts, and most degrade under sunlight. Tough and engineering resins exist and narrow the gap, at a price. If the part is a bracket that will be under load, or will live outdoors, or needs to survive being dropped, filament is generally the right process — and filament also reaches far larger sizes, since resin build volumes here top out well below the large filament machines.
Reading resin specifications
The one number that gets misread constantly is the panel resolution. '12K' or '16K' describes the LCD, not the print. What decides visible detail is the plate width divided by the pixels across it, in microns — and a 16K panel stretched over a wide plate can be coarser than a 9K panel over a narrow one. Every resin printer on this site lists that computed pitch, because it is the comparable number and the marketing badge is not.
