What it gets right

✓ Under £300 - low-risk way to get into 3D printing without regretting the spend.

Where it falls short

! Open frame - PLA and PETG only, realistically. Forget ABS or nylon done properly.
! Resin workflow - IPA baths, UV post-cure, nitrile gloves. Not a set-and-forget process.

Who this is for

Buying your first printer

Resin isn't a beginner's hobby. The chemicals, the IPA baths, the post-cure stations - it's a workflow. Start with FDM unless miniatures are specifically your reason for getting in.

Upgrading from an Ender or old Prusa

A resin printer is a sideways move, not an upgrade - different workflow, different outputs. Worth it if you want minis or detailed parts, pointless if you want faster PLA prints.

Workshop or small business

Not a workshop machine. Small build area, messy workflow, mid-range output quality. If you need resin for business, you want something above it in the range.

Verdicts are rule-driven from the spec sheet and current price (£189). They don't capture firmware polish, support quality, or reliability - so treat them as a sanity check, not a final answer.

Frequently asked

How sharp are prints on the ELEGOO Mars 4 Ultra 9K Resin? +

18 µm XY resolution. Fine enough for 28 mm tabletop minis, jewellery prototypes, and dental work. You will not see pixel artefacts on typical hobby prints.

What fits on the ELEGOO Mars 4 Ultra 9K Resin build plate? +

153.36×77.76×165 mm (2.0 L). Large enough for busts, multi-figure army trays and medium props sliced from a single file.

What else do I need to buy besides the ELEGOO Mars 4 Ultra 9K Resin? +

At minimum: a wash-and-cure station (£80-130), nitrile gloves, a bottle of IPA for washing, a funnel with filter, and somewhere ventilated to print. The printer is typically two-thirds of the total starting cost on a resin setup.

Is the ELEGOO Mars 4 Ultra 9K Resin worth £189? +

At £189 the ELEGOO Mars 4 Ultra 9K Resin is in hobby-entry territory - low-risk way to try the hobby. Expect older motion systems and basic feature sets, but print quality will surprise people coming from five-year-old reviews.
