— Use cases
When the Elegoo Mars 4 is the right call.
Best for
- Tabletop miniatures (D&D, Warhammer) at 25–50μm detail
- Jewellery masters and castable prototypes
- Dental and anatomical models with biocompatible resin
- Anyone wanting SLA detail on a small budget
Avoid for
- Large or bulky parts — the 153×77mm vat is small
- Functional load-bearing parts (standard resin is brittle)
- Print-and-go workflows — every print needs wash + UV cure
- Workspaces without ventilation or gloves
— Honest assessment

Cons
- Manual leveling — a paper-and-screws ritual before each session
- Small build volume limits batch size
- Mandatory IPA wash + UV cure post-processing
- Uncured resin is toxic — gloves and ventilation required

— Owner tips
What we'd tell someone unboxing one.
- 1Tilt models 30–45° and hollow them to cut resin use and suction
- 2Add drain holes to any hollowed model to avoid the vacuum-cup effect
- 3Wash 5–10 min in fresh IPA, then UV cure 5–15 min
- 4Re-level if the first layers stop sticking to the plate
