Best resin 3D printers under $400

Updated 26 September 2026 路 Live prices updated daily

Ranked off live Amazon.com prices plus the specs that actually matter on a resin machine: XY pixel size (finer is better), build volume, and light-source technology. Bigger numbers don't always mean better prints - but they do mean more headroom for miniatures, dental work and jewellery casting. Resin is messier than FDM; expect to spend time on wash, cure and nitrile gloves.

Matt's take on this budget

$400 is where 8K resin becomes standard and build areas start creeping towards Mars / Photon D2 size. If you're printing minis at 28 mm scale for tabletop, this is the tier where pixel size stops being a limitation. It's still not a workshop machine - the small bed makes big single prints awkward, and the lack of heating means winter print failures. A fantastic dedicated miniatures machine.

Frequently asked

What is the best resin 3D printer under $400? +

The shortlist above is live from Amazon. At this tier expect Elegoo Saturn 3/4, Anycubic Photon Mono M5s Pro and Phrozen Sonic Mini 8K to trade top slots as prices move. All are 8K-class machines with similar capability.

Is 8K resolution worth the upgrade over 4K? +

Yes for minis and jewellery, marginal for hand-sized props. Pixel size drops from ~35 碌m (4K) to ~22 碌m (8K) on typical screens - a visible step change on fine detail, less obvious on larger volumes.

How big are the prints at this budget? +

Typical build volumes at $400 are 218 x 123 x 230 mm or similar. Big enough for a handful of army minis or one medium bust. Larger-bed machines (Saturn 4 Ultra class) usually need closer to the $650 tier.

Ranking is driven by the spec sheet plus live price. Print quality on resin also depends heavily on the slicer, the resin itself, exposure tuning and post-processing - none of which are on the spec sheet. Treat this as a shortlist, read owner reports, then buy.
