What owners say

  • 14K detail on a Saturn-size plate. The M5s punches well above its price.

  • Anti-warping release is a real feature, not marketing. My failure rate dropped significantly.

  • Printed a half-scale bust in a single run. The Mega 8K S2 is in a class of its own.

Pros & Cons

Photon Mono M5s

  • +14K resolution on a Saturn-size plate is the highest resolution in this build volume class
  • +Anti-warping release mechanism measurably reduces failed prints on larger models
  • +218x123mm plate handles busts, terrain, and multi-model runs
  • −Pricier than the Elegoo Saturn 3 Ultra at comparable specs
  • −Discontinued: Anycubic support and firmware updates are ending

Sonic Mega 8K S2

  • +330x185mm plate is the largest resin build area in the consumer market at this price
  • +8K detail across the full plate without the hot spot degradation that plagues cheaper large-format LCDs
  • +Dual tilt release on a plate this size prevents the vacuum seal failures that ruin large prints
  • −$749 for a resin printer is a serious investment, plus $80-120 for a wash station to match
  • −High resin consumption: a full plate run uses 400-500ml, which adds up weekly
