Buy this if
- You already print resin and want to go from 12K to 16K detail without leaving Elegoo's ecosystem
- You want auto-leveling and a heated tank so prints are more consistent in a cold garage or workshop
- You want to monitor prints remotely, since the AI camera flags empty plates and warped models
Skip this if
- You have not printed resin before. The step up from FDM (post-curing, ventilation, PPE) matters more than which resin printer you buy first
- You need a bigger build volume than 211.68 x 118.37 x 220 mm. Elegoo's own Jupiter 2 or the Anycubic Photon Mono M7 Max go larger
- You only print standard resin at default settings, where the jump from 12K to 16K is hard to see
What buyers are actually asking
Elegoo's own product page carries a running Q&A thread with over 55 questions as of September 2026. The recurring topics are logistics and compatibility, not print failures:
327.4 x 329.2 x 548 mm (L x W x H) with the lid closed. Elegoo recommends roughly 300 mm of extra clearance above and behind the machine to open the lid fully.
Yes, a tempered glass LCD protector ships pre-installed.
Yes, per Elegoo's support answers on the product page.
Any standard 405nm UV resin. Elegoo's own resin lines are sized for this printer, but they are not required.
