For a fast, fixed-bed CoreXY printer
Phrozen Arco
A CoreXY FDM printer with a fixed bed, a 300 × 300 × 300 mm nominal build volume, and a speed advertised up to 1,000 mm/s per Phrozen.
In short The Phrozen Arco is an open-frame filament (FDM) 3D printer with a 300 × 300 × 300 mm (11.8 × 11.8 × 11.8 in) build volume. Phrozen claims a 1,000 mm/s top speed, a 300 °C (572 °F) nozzle and a 110 °C (230 °F) bed; the printer measures 492 × 475 × 620 mm (19.4 × 18.7 × 24.4 in) and weighs 22 kg (48.5 lb).

FDM · Open frameWhy 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.

How much space does it need?
The Phrozen Arco measures 492 × 475 × 620 mm (19.4 × 18.7 × 24.4 in) for a 300 × 300 × 300 mm (11.8 × 11.8 × 11.8 in) build volume: the dashed box is the printer, the solid cube the largest theoretical part, about 19% of the machine’s volume. Add room for the spool or multicolor unit, cables and ventilation.

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.
