Variants & sibling models — and how to tell them apart (spec-contamination risk)Larger sibling of the Guider 3 (300x250x340) and distinct from the Guider 3 Ultra, which is dual-extruder, 330x330x600 and 350 °C.

Specifications quoted for one head do not apply to the other. Not to be confused with QIDI's i-Mate or the X-CF Pro[3][2]

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.
