Longer Orange 4K V2 vs QIDI X-CF Pro
Head-to-head 3D printer comparison, 2026
Comparing FDM to resin? The Longer Orange 4K V2 ($199, RESIN) and QIDI X-CF Pro ($599, FDM) use fundamentally different technologies. FDM melts filament layer by layer; resin cures liquid with UV light. Here's how they stack up.
Our Verdict
The QIDI X-CF Pro takes the crown with 6.8/10 vs 6/10. It pulls ahead in Print Quality, Reliability. That said, the Longer Orange 4K V2 saves you $400 and wins on Value.

Pros & Cons
Longer Orange 4K V2
+Better light uniformity than the V1 means fewer dark patches at plate edges
+WiFi at $199 is a feature the original didn't have
+Compact enough to store in a drawer when not printing
−4K resolution is dated: the Elegoo Mars 4 offers 7K for $149 with better community support
−120x68mm plate is small even by entry-level standards
−Longer's support community is thin: problems are harder to solve than on Elegoo hardware
QIDI X-CF Pro
+One of the few sub-$600 printers with a genuine 60°C heated enclosure for PA-CF and PPS-CF
+Hardened steel nozzle ships standard — no upgrade needed for carbon fiber out of the box
+HEPA + active carbon filtration — safe for indoor use with engineering filaments
+Linear rails on all axes mean less positional drift on long industrial prints
+Proven track record in light manufacturing since 2021
−60-100mm/s print speed is 6x slower than modern CoreXY machines — long print times
−2021 vintage hardware; newer QIDI models (X-Plus 4, Tech Max) offer more for similar money
−Dual extruder adds mechanical complexity without multi-color usefulness for most users
−21.5kg — not portable, bench-only
−Slicer integration (Simplify3D profiles) trails modern Bambu/Creality ecosystems
