Why consider it?

Two CNC-machined linear rails on the Y axis and a swappable high-flow 0.6/0.8 mm nozzle, for large parts without multiplying prints.

What to verify

Open frame by default: a separate 'Enclosure Plus' accessory is offered for anyone who wants to stabilize ABS on a volume this large.

The specifications that matter

Process: FDM
Nominal build volume: 450 × 450 × 470 mm
Enclosure: Open frame
Multicolor: No multicolor system on this machine, per Creality's listing.
Materials: PLA, PA (nylon), heat-resistant ABS, PLA-wood, PLA-CF, flexible TPU, and PETG per Creality.

Allow room for supports and the chosen orientation. Confirm the exact nozzle, feeder, included accessories and installation clearance against the manual and seller’s listing.

Which projects is it for?

The CR-M4 is an open-frame FDM printer with a 450 × 450 × 470 mm nominal build volume per Creality, a footprint built for bulky models printed as a single piece or for batch runs on one plate, with little post-processing.

Two CNC-machined hardened-steel linear rails on the Y axis aim for stable transmission despite the weight and inertia of a bed this size, with 25-point automatic CR Touch leveling and Z-offset advertised at 0.05 mm precision.

Materials and configuration

Creality advertises compatibility with PLA, PA (nylon), heat-resistant ABS, PLA-wood, PLA-CF, flexible TPU, and PETG, with a nozzle heating up to 300°C thanks to a 50 W heating cartridge.

The swappable high-flow 0.6/0.8 mm nozzle increases extrusion flow for large parts, a useful factor for cutting print time on a volume this size.

What the bundle includes or not

The 470 × 470 mm heated bed reaches 60°C in an advertised 160 seconds per Creality, an important factor for the first layer on a surface this large. The CR-M4 still stays open-frame by default.

An 'Enclosure Plus' (1000 × 800 × 1000 mm) is offered as a separate accessory, with insulation and flame-retardant materials, for anyone who wants to stabilize printing of ABS or other cooling-sensitive materials. Check the retailer's listing precisely to see whether your offer includes it.

Alternatives to compare

For a slightly more compact, more accessible open frame, the Ender-5 Max reaches 400 × 400 × 400 mm. For an enclosed chassis at a more modest volume, the K2 Plus adds a heated chamber on 350 × 350 × 350 mm.

The large-format buying guide covers the criteria for choosing a printer this size, and the Creality page covers the rest of the manufacturer's lineup.

Frequently asked questions

Do you need the Enclosure Plus to print ABS?

It's not included by default: the CR-M4 is open-frame out of the box, and the enclosure remains a separate accessory. Without it, ABS stays more prone to warping on a bed this size.

Does the bed heat up fast enough for regular use?

Creality advertises 60°C in 160 seconds for the 470 × 470 mm bed, which is fast given the surface being heated, though the real time depends on ambient conditions.

What's the difference with the Ender-5 Max?

The CR-M4 offers a slightly larger volume (450 × 450 × 470 mm versus 400 × 400 × 400 mm) and a swappable high-flow nozzle, while the Ender-5 Max stays a more accessible option for large format.
