Anycubic Kobra S1

Buy/Wait:Caution

First-generation product — no release history to base predictions on

Best for: Makers who want an enclosed CoreXY at a prosumer price for PLA, PETG, ABS, and ASA — and prefer the Anycubic ecosystem. For reliable PA or PC printing, consider the Kobra S1 Max or Qidi Q2 which offer active chamber heating.

Both

PLAEasy to print, no enclosure needed — everyday parts

PETGTougher, slightly flexible, moisture-resistant

PA-CFCarbon-fibre nylon — very stiff, abrasive to standard nozzles

PCPolycarbonate — extremely tough, challenging to print

Why buy each?

Anycubic Kobra S1

Enclosed CoreXY at 600 mm/s

The Kobra S1 combines an enclosed build chamber with 600 mm/s CoreXY motion — offering improved heat retention over open-frame printers for ABS and ASA.

Anycubic ecosystem at prosumer price

Brings Anycubic's value-focused approach to the enclosed CoreXY segment — competing with Qidi Q2C and Bambu P2S at a lower price point.

250×250×250 mm build volume

A practical cubic build volume well-suited for functional mechanical parts, enclosures, and prototypes.

Prusa Research XL

Tool-changer multicolor — no purge waste

Unlike filament-switching AMS/MMU systems, the XL physically swaps print heads. Each material has its own nozzle, eliminating purge towers entirely and enabling true multi-material prints.

360×360×360 mm build volume

One of the largest build volumes available in a CoreXY printer at this price point — suited for large props, architectural models, and batch production.

Fully open source and serviceable

Every component is documented, parts are stocked for years, and the community has developed hundreds of modifications and improvements.
