What this printer gets right and wrong
- ✓ Under $300 - low-risk way to get into 3D printing without regretting the spend.
- ! 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.
Head-to-head spec + price table against the ELEGOO Mars 4 Resin. Verified printers on this marketplace only.
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.
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.
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 ($185). 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 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 Resin build plate? +
153.36×77.76×175 mm (2.1 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 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 Resin worth $185? +
At $185 the ELEGOO Mars 4 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.
