For a fast, open-frame large format

Documentary analysis · Not personally tested
Specification sources reviewed 2026-09-12. These are manufacturer claims, not measurements by Find My 3D Printer.
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.
The specifications that matter
- Process
- FDM
- Nominal build volume
- 300 × 300 × 400 mm
- Enclosure
- Open frame
- Multicolor
- No stock multicolor system; a single extruder with dual-gear direct drive.
- Materials

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.
