Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)QIDI X-Smart 3, listed in QIDI navigation as X-Smart3[1][2]UltiMaker S7[3]
Release date (announcement and actual shipping)Not published by QIDI on the pages checked (Aug 2026)[1][2]Not documented
Street price (USD; dated snapshot per entry)$399 on QIDI's official US page, which routes purchases to its AliExpress and Amazon stores; checked Aug 2026[2]$5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[3]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Entry model of the 3-series. Unlike the X-Plus 3 and X-Max 3 it has no heated chamber, a 300 °C rather than 350 °C hotend, a brass rather than copper-alloy/hardened-steel nozzle head, and no Ethernet. It shares the Cortex-A53 board with them, so control-board specs must not be read as shared print specs[1][4][5]Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[3][6][7]
Market position: superseded? successor announced?Not documentedSuperseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[7][8]

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.
