Choosing the best small resin 3D printer for miniatures starts with two different sizes: the chassis that fits your desk and the build volume that fits your models. The five picks below compare published specifications, with four compact machines and the larger Saturn as a batch-printing option. Compare XY pixel size alongside footprint: the 9K, 10K and 16K labels describe pixel counts, not the space a printer occupies or the detail a finished miniature will retain.

Figures are from each vendor’s page or the 3DJake listing linked below. Prices are historical snapshots, including the Mars 5 Ultra list price quoted by 3DWithUs; check the seller before ordering. Chassis dimensions come from the official product pages, with Phrozen’s centimetres converted to millimetres. Footprint is width x depth; the third dimension is closed-cover height, not operating clearance.
Small resin 3D printers: footprint and desk fit
Among these five picks, the Photon Mono 4 has the smallest published base at 230 x 235 mm and the lowest closed height at 391 mm. The Mono 4 Ultra occupies almost the same base but is 430 mm tall. Both list a 153.4 x 87 x 165 mm build volume, so choosing the smaller chassis does not sacrifice model capacity between those two.
The Mars 5 Ultra needs 260 x 268 mm of desk, while the Sonic Mini 8K S needs 290 x 290 mm despite its Mini name. The Saturn 4 Ultra 16K is the larger-capacity alternative at 327.4 x 329.2 x 548 mm. Choose it when its extra build area serves your batches, rather than assuming every miniature job needs that much printer.
Before buying a small printer, mark its base on the work surface and check the manual for cover movement and access. Plan separate space for the plate, wash containers, drying and curing equipment; the resin starter kit covers that workflow. A chassis fitting under a shelf does not establish that you can remove its cover or handle a dripping plate there.
Why pixel size matters more than the K number
An MSLA printer masks a 405 nm backlight through an LCD, so the smallest feature it can draw in XY is one pixel. Elegoo’s 9K panel is 8520 x 4320 at 18 µm; Anycubic’s 10K panel is 9024 x 5120 at 17 µm. One micron is not visible on a 32 mm figure. The 16K Saturn is 14 x 19 µm, finer on one axis and coarser on the other, and the larger axis limits the finest edge.
Layer height is the other half. AmeraLabs printed the same dragon at 100, 80, 50, 20 and 10 µm on a Mars 4 DLP and found 50 µm gave crisp edges with faint lines that vanished under primer; 20 to 10 µm was “very subtle, invisible post-paint”. Their times: 58 min at 100 µm, 2 h 18 min at 50 µm, 3 h 52 min at 20 µm and 7 h 27 min at 10 µm. Buy the pixel size first, then print at 0.05 mm.
Elegoo Mars 5 Ultra: the default pick for 28 to 75 mm figures
For single characters, squads of five or six, or 75 mm display pieces, buy the Mars 5 Ultra. The 3DJake spec sheet lists an 18 µm panel over 153.36 x 77.76 x 165 mm, a 25-LED COB source at 405 nm and 150 mm/h.
The screen is not why. Instead of lifting the plate to peel each layer, the Mars 5 Ultra tilts the vat, which lowers peel force on spear shafts and banner poles, the parts most likely to tear off a support on a conventional lift. It also self-tests and levels the platform before every print, so no leveling paper and no Z-offset guesswork. 3DWithUs printed 32 mm and 75 mm figures on the default 0.05 mm, 2.5 s profile, reported sharp detail and intact lattice work, rated it 4.8 out of 5, and quoted $338 list with $269 to $299 street. Their complaints: a plate that is awkward to clean between the stand-offs, and a stale demo file. Skip it for terrain or 10-figure batches; the 77.76 mm Y axis fills fast.
Anycubic Photon Mono 4 Ultra and Mono 4: same 17 µm screen, two budgets
Anycubic sells the same 10K panel in two chassis. The Photon Mono 4 Ultra is $344, pairs a COB source with a Fresnel lens, adds failed-print, resin-residue, resin-level and film-lifespan monitoring, and reaches 120 mm/h at 0.1 mm with High Speed Resin 2.0 (80 mm/h on standard resin). The 3DJake listing adds 153.4 x 87 x 165 mm, a 0.02 to 0.15 mm layer range, at least 3500 µW/cm² and USB, Wi-Fi and LAN. No tilt mechanism is listed, so the speed rides on the resin, not the peel. Pick it over the Mars for Ethernet, the extra 9 mm of Y, or a printer that pauses itself when a part detaches.
The plain Photon Mono 4 is the budget answer: the same 17 µm panel and volume for $252 ($240 on sale at the time of writing), with 4-point manual leveling, USB only and 50 mm/h on standard resin. Detail per pixel is identical. You give up speed and convenience, not the miniature.
Phrozen Sonic Mini 8K S: 22 µm and USB only
The Sonic Mini 8K S is listed at $270 on Phrozen’s store: 7.1-inch 8K panel, 22 µm, 165 x 72 x 170 mm, 0.01 to 0.30 mm layers, 80 mm/h, manual leveling, USB only. Check availability before choosing it. It may suit an existing collection of Phrozen resin profiles; compare the Mono 4 if footprint and pixel size are the priority.
Elegoo Saturn 4 Ultra 16K: for squads, terrain and busts
For ten figures a plate or a 200 mm bust, the Saturn 4 Ultra 16K is the pick: 10-inch 16K panel, 14 x 19 µm, 211.68 x 118.37 x 220 mm, 0.02 mm Z accuracy, 150 mm/h, USB and Wi-Fi. Elegoo launched it in January 2025 at $519.99 with the Mars-style tilt release, a tank heater that holds resin at 30 °C and a camera for failure detection. The heater matters: cold resin is the usual reason a winter print lets go of the plate.
Creality’s HALOT-MAGE S is the non-Elegoo option, 10.1-inch 14K at 223 x 126 x 230 mm with USB, Ethernet and Wi-Fi, but its pixels are 16.8 x 24.8 µm. That 24.8 µm axis is coarser than every 7-inch machine here: a volume buy, not a detail buy.
Settings to start with, and how to check them
Start at 0.05 mm layers with the vendor profile for your resin, then run the test in our exposure calibration guide before trusting it. Siraya Tech, whose Fast resin is a common miniature choice, publishes per-printer profiles for Elegoo, Anycubic and Phrozen, recommends the Medium support preset for small prints and Heavy for large ones, wants resin above 20 °C, and specifies a 1 to 2 minute post-cure at 395 to 405 nm. Our wash and cure guide covers the solvent and timing.
To verify, print one figure at 0.05 mm and inspect the face, the weapon edge and the thinnest strap. Blurred eye sockets or bloated straps can indicate over-exposure; a strap that snapped at the support can indicate under-exposure or a peel problem. If you also run FDM, the layer height guide for FDM miniatures covers that process, and our resin vs FDM decision guide helps decide which process suits a part.
Frequently asked questions
What is the smallest resin 3D printer worth buying?
Of the five models compared here, the Anycubic Photon Mono 4 has the smallest published footprint: 230 x 235 mm, with a 391 mm closed height. Its 17 µm XY pixels and 153.4 x 87 x 165 mm build volume make it a compact option for miniature work based on specifications. This is a comparison within this shortlist, not a claim that it is the smallest printer on the whole market. Allow additional workspace for washing and curing.
Who should buy which
- Single figures and small squads, minimum fuss: Elegoo Mars 5 Ultra, tilt vat and auto-leveling at 18 µm.
- Same size with Ethernet and self-pausing failure detection: Anycubic Photon Mono 4 Ultra at 17 µm.
- Tightest budget without giving up resolution: Anycubic Photon Mono 4, $252, manual leveling.
- Already invested in Phrozen resins and profiles: Sonic Mini 8K S, if the September restock holds.
- Batches, terrain, busts: Elegoo Saturn 4 Ultra 16K. Skip the HALOT-MAGE S for detail work because of its 24.8 µm axis.
- Skip the professional tier for miniatures; a 50 µm pixel is the wrong tool for a 28 mm face.
