| Class | RESIN | COREXY |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Phrozen Sonic Mini 8K S 7.1" LCD 3D Printer. Manufacturer number 51010040501102[1][2][3] | QIDI Max4, sold as "Max4 High-Temp 3D Printer"[4][5] |
| Release date (announcement and actual shipping) | Not documented | Not published on QIDI's product page; the machine is listed as the current replacement for the discontinued X-Max 3 (checked Aug 2026)[4][6] |
| Street price (USD; dated snapshot per entry) | $270.00 on us.phrozen3d.com, backordered with an end-of-September ETA, checked Aug 2026. The collection page rendered it as unavailable on the same day[3][2] | $1,099.00 standard on us.qidi3d.com against a $1,149.00 compare-at price, checked Aug 2026. Variants: Polar Cooler bundle $1,249.00 (was $1,348.00), Max4 Combo $1,249.00 (was $1,299.00), Combo + Polar Cooler $1,399.00[4] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Phrozen's 7.1-inch line is easy to confuse: the Sonic Mini 8K S ($270) sits beside the older Sonic Mini 8K ($340, sold out) and the 5.5-inch Sonic Mini ($129.99). The 10.1-inch Sonic Mighty family is a different size class entirely. The 8K S is the only one of the group with a single linear rail and a lead screw rather than a ball screw[2][1][3][7] | Four variants at the US store: Standard, Polar Cooler bundle, Combo (adds QIDI Box), Combo + Polar Cooler. Direct replacement for the X-Max 3, which it differs from on every headline figure: 390x390x340 vs 325x325x315, 800 vs 600 mm/s, 370 vs 350 °C. Do not carry X-Max 3 specs across[4][6] |

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
