CONCLUSION

    The QIDI MAX 4 COMBO lands as a genuinely capable high‑speed, high‑volume machine that delivers on its core promises. Its strengths are easy to appreciate, fast and smooth motion, consistently clean print surface quality, a large 390x390x340mm build area, and the practical benefits of the Polar Cooler, which keeps extrusion stable during long or high‑temperature jobs. Add the multi‑color capability via the QIDI box (although filament waste when printing multi-color models is still a thing) and the actively heated enclosure, and the Max 4 Combo becomes a flexible platform that handles everything from PLA to engineering‑grade materials with confidence. Still, it isn’t without friction points. Software bugs in relation to the slicer and firmware may occasionally interrupt an otherwise polished workflow (also the reason as to why I couldn’t use a timelapse for this review), the bottom handles aren’t the most ergonomic for moving a machine of this size and weight, and the need for separate power connections for both the box unit and the Polar Cooler adds a bit of cable clutter. Taken together, the Max 4 Combo stands out as a fast, spacious, and well‑engineered printer whose minor quirks are outweighed by its performance and versatility.

    Right now, the Max 4 Combo by QIDI retails for USD1199 inside the USA (us.qidi3d.com – plus a 5% discount when you subscribe to their newsletter) and for 1199Euros inside the EU (eu.qidi3d.com – 5% discount also available) and so it’s priced more or less the same as its direct competition (keep in mind that the Polar Cooler is sold extra for USD179.10/179.10Euros). Cost aside whether it’s speed, print quality, print size, enclosure features and multi-color prints the QIDI Max 4 Combo delivers as advertised and for that it gets the Golden Award.
