Why consider it?

A flying gantry on XY linear rails with a fixed bed to reduce wobble, DEP extrusion with an industrial heat pipe, and acceleration advertised up to 40,000 mm/s² per Phrozen.

What to verify

The PentaShield enclosure is sold as an option, not included by default; the 1,000 mm/s speed is measured with a CHT nozzle and a specific PLA per Phrozen.

Which projects is it for?

The Arco is an open-frame CoreXY FDM printer with a fixed bed and a flying gantry, for a 300 × 300 × 300 mm nominal build volume per Phrozen. This fixed bed, rather than a moving bed as on some other CoreXY printers, aims to reduce model wobble and keep a stable center of gravity on tall parts.

Phrozen positions the Arco for cosplay props, bulky single-piece prints, and rapid prototyping, with a speed advertised up to 1,000 mm/s under specific conditions and acceleration up to 40,000 mm/s².

Materials and setup

The nozzle heats up to 300°C, and Phrozen advertises compatibility with PLA, PETG, ABS, ASA, TPU, and nylon, with carbon-fiber or glass-fiber composites possible through dedicated nozzles sold separately. DEP (Direct Extrusion Path) extrusion uses a 10 mm industrial heat pipe to limit clogging.

The four-zone heated bed reaches 100°C in two minutes with over 90% heat uniformity per Phrozen, which helps limit warping on parts that cover a large part of the plate.

What the bundle includes or not

Klipper firmware is advertised as pre-installed, with a flexible PEI plate and automatic leveling per Phrozen. The PentaShield enclosure, presented as cutting noise by 15% and filtering odors, remains an optional accessory not included in the base configuration.

The Chroma Kit multicolor module, for printing up to four colors, is also sold separately from the base machine; the exact box contents should be checked on the retailer's listing.

Alternatives to compare

For a factory-enclosed chassis on a comparable volume, the Creality K1 Max is a direct comparison from a different brand segment. For built-in multicolor without a separate module, Elegoo's Centauri Carbon 2 follows a different approach.

The functional parts guide and the multicolor buying guide help place the Arco against these alternatives before buying.

Frequently asked questions

Does the Arco really reach 1,000 mm/s in everyday use?

That speed is advertised by Phrozen under specific conditions: a high-flow CHT nozzle, Phrozen High-Speed PLA, and a 0.2 mm layer height. Real-world results depend on the filament and the model being printed.

Is the enclosure needed to print ABS?

Phrozen recommends the PentaShield enclosure for ABS and nylon to limit odors and stabilize temperature, but it remains an accessory sold separately, not stock equipment.

How does multicolor printing work on the Arco?

It runs through the separately sold Chroma Kit module, with dedicated feed tubes for faster color changes per Phrozen, on a model that does not offer this feature by default.
