Anycubic Kobra S1 Max: Large build volume, more materials – an overview of the new high-speed CoreXY.

Anycubic is upping the ante and presenting the Kobra S1 Max, the largest and most powerful model in its flagship series. The manufacturer combines an exceptionally large build volume with high printing speed and remarkably broad material compatibility – clearly targeting ambitious makers, professional users, and workshops that want to process more than standard PLA.

The S1 Max is expected to be delivered before the end of the year and is already available for pre-order with a deposit.

Large build volume meets fast CoreXY performance

As the name suggests, the Kobra S1 Max is a significantly larger sibling of the S1.

The device uses a build volume of 350 × 350 × 350 mm – larger than many devices in its class, including the Prusa CoreOne L (300 × 300 × 330 mm) or the Bambu Lab H2S (340 × 320 × 340 mm).

This makes the printer ideal for users who want to print large models without cutting: props, helmets, functional assemblies and individual technical components benefit enormously from this space.

Despite its large size, the S1 Max does not stop at a classic installation space upgrade:

It also brings CoreXY performance, including:

• Maximum print speed 600 mm/s
• Standard speed 300 mm/s (realistic and practical)
• 20,000 mm/s² acceleration

This brings it up to the current performance generation of other high-speed devices.

Compatible with technical and abrasive materials

Anycubic clearly focuses the S1 Max on high-performance materials.

The printer supports, among other things:

• PC (Polycarbonate)
• nylon
• Carbon fiber reinforced filaments
• ASA / ABS
• PLA, PETG and standard materials

This is made possible by a strong material unit:

• 350 °C hotend temperature
• 120°C heated print bed
• 65 °C heated construction chamber
• Hardened steel nozzle (for abrasive filaments)

Especially with PA-CF, PC and heat-resistant plastics, a heated chamber is a crucial advantage.

The S1 Max thus meets requirements that were previously mostly reserved for industrial systems.

New ACE 2 Pro system & up to 16 material spools

A large part of the update concerns material management.

Anycubic introduces the new ACE 2 Pro multicolor/multimaterial system with this device.

Not all the details are available yet, but:

• Up to 16 coils can be processed.
• Presumably via four ACE-2 Pro modules
• Newly designed operating logic & automatic material handling

In addition, there is an improved 720p camera solution in the enclosed build chamber (a significant improvement compared to the 480p of the S1).

Prices, pre-sale & availability

The Kobra S1 Max Combo is already available for pre-order.

Anycubic is offering an attractive introductory promotion:

• €50 deposit = €100 discount
• Full payment due from November 25th.
• Shipping shortly afterwards in order of receipt of payment.
• Introductory price from €799
• Regular price from February 2026: €999

Whether the subsequent price increase will remain in place is currently unclear.

Conclusion: A printer for big ideas and demanding materials

With the Kobra S1 Max, Anycubic is launching a printer that is not only large – but has also been consistently designed to use modern high-speed and high-performance materials.

For creators, makers, workshops and semi-professional businesses, the device could represent an exciting alternative to significantly more expensive systems.
