For a fast, open-frame large format

Artillery Sidewinder X4 Plus

An open-frame FDM printer with a 300 × 300 × 400 mm nominal build volume, a Klipper board, and a top speed advertised at 500 mm/s per Artillery.

In short The Artillery Sidewinder X4 Plus is an open-frame filament (FDM) 3D printer with a 300 × 300 × 400 mm (11.8 × 11.8 × 15.7 in) build volume. Artillery claims a 500 mm/s top speed and a 300 °C (572 °F) nozzle.

Why consider it?

A 64-bit Klipper board, a top speed advertised up to 500 mm/s with 250 mm/s recommended, 36-point auto bed leveling, and metal linear rails on the XY axes per Artillery.

What to verify

The frame stays open with no enclosure, so ABS and nylon benefit from a warm, draft-free room. Exact box contents (95% pre-assembled) should be checked on the retailer's listing.

Which projects is it for?

The Sidewinder X4 Plus targets makers who want a large 300 × 300 × 400 mm plate per Artillery without moving to a fully enclosed machine, for tall parts (stands, props, long mechanical pieces) or several objects on one plate.

The advertised top speed of 500 mm/s, driven by the Klipper board and 12,000 mm/s² acceleration per Artillery, aims to cut print times on parts this size, while 250 mm/s stays the recommended everyday setting.

Materials and setup

The all-metal nozzle heats up to 300°C per Artillery, covering the advertised PLA, TPU, PETG, ABS, and nylon. The dual-gear direct drive extruder targets more consistent extrusion, useful on flexible filaments like TPU.

The open frame with a rear tie bar and triangular structure keeps rigidity on a plate this size, but without an enclosure: ABS and nylon benefit from a heated room to limit warping.

What the bundle includes or not

Artillery advertises a machine shipped 95% pre-assembled, with a magnetic flexible PEI sheet, 36-point auto bed leveling, and a 4.3-inch color touchscreen. The exact accessories included (spare nozzles, tools) should be checked on the retailer's listing.

WiFi connectivity enables remote printing and slice preview per Artillery, useful for starting a job without staying at the machine.

Alternatives to compare

For a more compact footprint with the same Klipper architecture, the Sidewinder X4 Pro covers a 240 × 240 × 260 mm plate in a smaller machine. For an enclosed chassis instead of an open one, the Creality K1 Max is worth comparing at a similar volume.

The beginner's buying guide helps judge whether a large open-frame plate fits your projects better than a smaller, enclosed machine.

Frequently asked questions

What is the build volume of the Artillery Sidewinder X4 Plus?

Artillery lists a 300 × 300 × 400 mm (11.8 × 11.8 × 15.7 in) build volume (width × depth × height). That is the largest theoretical part size; supports, brim and orientation reduce the usable space.

How fast is the Artillery Sidewinder X4 Plus?

Artillery claims a top toolhead speed of 500 mm/s and 12,000 mm/s² acceleration. Real print times depend on the material, the profile and the part; this is a manufacturer figure, not our measurement.

Is the Artillery Sidewinder X4 Plus enclosed?

No, it is an open-frame printer. It suits PLA and PETG; ABS and ASA are better handled by an enclosed machine. Its nozzle reaches 300 °C (572 °F).

Can the Sidewinder X4 Plus print ABS without an enclosure?

The frame stays open per Artillery; ABS is still possible but benefits from a heated, draft-free room to limit warping on a plate this large.

What's the difference from the Sidewinder X4 Pro?

The X4 Plus offers a 300 × 300 × 400 mm plate versus 240 × 240 × 260 mm for the X4 Pro per Artillery, for larger parts, with a similar Klipper-based architecture.

Does the printer arrive ready to print?

Artillery advertises 95% factory pre-assembly; final assembly steps and calibration are still left to the user before the first print.
