Summary

A large-format open-frame FDM printer with a 420 × 420 × 500 mm build volume and the ACE Pro four-color filament system, expandable to eight colors. Buy it for big cosplay and functional parts, but weigh the unit-to-unit quality variance and the thin spare-parts supply before you commit.

Strengths

  • The 420 mm bed handles full-size helmets, props and large functional parts without splitting them.
  • Automatic bed leveling works reliably across the whole plate.
  • Print quality at speed is good in PLA and PETG.
  • The ACE Pro dries filament while printing, something the Bambu AMS does not do.
  • The quick-release nozzle and removable toolhead cutter make clogs easier to clear.
  • Quiet for its size, around 60 dB in standard mode.

Weaknesses

  • Bed adhesion gets dicey on prints longer than 12 hours, especially near drafts.
  • Multicolor purge waste is heavy: one 220 g eight-color model used 357 g of purged filament.
  • Quality varies unit to unit; some units need multiple part replacements within months.
  • Spare parts are thin and support quality is inconsistent.
  • The open frame limits warp-prone materials like ABS and ASA without an enclosure.
  • The advertised 600 mm/s is a ceiling; expect closer to 200 mm/s in practice.

Speed and print quality

Anycubic markets 600 mm/s, but that is a ceiling. Tom’s Hardware measured real-world cruising closer to 200 mm/s, and Anycubic’s own FAQ puts a Benchy at 18 minutes on a tuned profile and 48 minutes at the recommended 300 mm/s. Print quality at speed holds up in PLA and PETG, and the dual Y-axis motors help keep heavy parts steady on the big bed.

Multicolor and the ACE Pro

The ACE Pro feeds four spools through one nozzle and dries filament at up to 55°C while printing, which the Bambu AMS does not. A second ACE Pro and the printed eight-color hub take it to eight colors, but neither the hub nor the extra tubes are in the standard box. Color changes are slow and wasteful: 3D Printer Stuff timed each swap at 18 to 25 seconds, against 12 to 15 seconds for the Bambu AMS, and a 220 g eight-color print in Tom’s Hardware’s test used 357 g of purged filament. TPU will not run through the ACE Pro, so feed it from a single spool instead.

Bed adhesion and the open frame

The big bed can lose heat near drafts, and testers and owners report adhesion problems on prints longer than 12 hours; a glue stick or a plate upgrade helps. The open frame also means ABS and ASA are not recommended without an enclosure, and the bed needs just under a meter of clearance on the bench for travel.

Reliability, repairs and running costs

Quality varies unit to unit. 3DnMe tested four units and found loose belts, alignment problems and defective components, while some owners report 700 to 800 hours before a first significant repair. The quick-release nozzle swaps without disconnecting heater wiring, and the removable toolhead cutter opens the extruder for clogs. Spare parts are thin: the official store lists few items, though the Anycubic wiki carries replacement guides for the print head, nozzle, hotbed, motherboard and ACE Pro mainboard. Recurring costs are filament (including purge waste), replacement nozzles, glue stick, an optional camera, a hardened nozzle for abrasive filament, and grease. One 5-month owner update reported a bed that stopped heating from a harness short; Anycubic offered a full parts replacement or a new printer.

Is it worth it?

At $449 to $499 the Combo is strong value for large-format multicolor printing. 3D Printer World listed the base printer at $349, the Combo at $499 and the eight-color Combo at $698 (3D Printer World, September 2026), and an anniversary sale listed the Combo at $449 (TipRanks, September 2026). Anycubic’s US store ran the Combo at $569 from $899 (Anycubic US store, May 2026). The Kobra 3 Max V2 Combo with the ACE 2 Pro and full-metal hotend is $569 (3D Printer World, September 2026), and the ACE 2 Pro upgrade bundle is $339, down from $469 (Anycubic Canada, 2026). Above the Combo’s sale prices, weigh the unit-to-unit variance, thin parts supply and inconsistent support against the V2.

Which model this is

This page covers the Kobra 3 Max Combo with the first-generation ACE Pro (55°C drying, brushed feed motors). The base Kobra 3 Max is the same printer without the ACE Pro and prints one color. The newer Kobra 3 Max V2 is a different machine, not a firmware update: it adds a full-metal hotend, a hardened steel nozzle rated to 350°C and the ACE 2 Pro with 65°C drying and brushless motors. The two ACE generations are not interchangeable, and the nozzle is proprietary to this machine. The listing for this bundle is ASIN B0F1Y299NN.
