| Our verdict | The standalone P1S provides the essential enclosed CoreXY chassis for $399 without the cost and complexity of the AMS unit. The passive thermal enclosure retains sufficient heat to print warp-prone polymers such as ABS and ASA reliably. It is a workhorse option for makers prioritizing functional structural parts over multi-material capability. | The Mars 5 Ultra brings automated tilt-release mechanics and improved connectivity to Elegoo's compact resin lineup. While it reduces print failures and simplifies workflow, toxic photopolymer resins still mandate a dedicated exhaust extraction setup. It suits detail-focused makers who want a streamlined resin printing experience in an appropriately ventilated workshop. |

Sources and limits
This page summarizes our research reviews of Amazon listings, listed specifications and captured buyer ratings. It is not a hands-on test. Scores are editorial assessments, not measured performance; prices are recorded snapshots and may change. A category can include both main products and accessories, so its overall price range is not the cost of a complete setup.
Most recent product record update: September 14, 2026. Individual records may be older; this is not a verification date for every claim. Prices on this page were read from the listings Nov 8, 2026.
