Pros & Cons
Elegoo Saturn 4 Ultra
+218x123mm plate fits a full Warhammer squad in one run, not two
+12K resolution holds up just as well as the Mars at 14K for most print sizes
+Tilt release is worth it at this plate size: peel forces on large prints are brutal without it
+Terrain and base tiles look genuinely stunning at this resolution
−Resin consumption goes up fast when you're filling a plate this size
−Post-processing for a full plate run takes 45-60 minutes minimum
−The purifier helps but a plate this big curing kicks up more fumes
Prusa Mini+
+Prusa's reputation for reliability is earned — this is their most-owned printer globally
+PrusaSlicer profiles are the gold standard; third-party slicers treat Prusa as the reference
+Open-source means every component is documented, replaceable, and community-supported
+SuperPINDA gives consistently excellent first layers without manual tramming
+4kg makes it genuinely portable — fits in a carry-on with room
−180×180×180mm is small — limits to desk accessories, figurines, and small functional parts
−180mm/s is slow compared to Bambu or Creality CoreXY machines
−Semi-enclosed means ABS warping is still a risk without an aftermarket enclosure
−Prusa charges a premium; the hardware isn't exceptional by 2025 standards
