Anycubic Kobra S1 Combo Review: Fast Multi-Color 3D Printing

The Anycubic Kobra S1 Combo features a substantial design, with owners frequently describing its build quality as 'heavy duty' and 'solid.' The printer's enclosure is often compared to a 'minifridge' for its sturdiness, suggesting a stable printing environment. The ACE PRO filament system, a key component of the combo, is generally regarded as well-integrated and contributes to the printer's overall robust appearance. However, some users report design flaws within the ACE PRO, specifically with plastic tabs in sensors that can cause issues, though updated units reportedly use metal replacements.

Many owners find the Kobra S1 Combo straightforward to set up, reporting readiness for first prints within 30 minutes. The auto-leveling function contributes to its 'almost dummy proof' reputation. For new users, it provides a 'best first time experience.' However, the ACE PRO unit introduces some complexity; loading filaments can be 'tricky if the feed is not straight,' and its sensors occasionally fail to recognize or feed filament, particularly from the third spool slot. Some users experience initial frustration with the slicer software and its inability to communicate with the printer, necessitating USB transfers for files.

When operating correctly, the Kobra S1 Combo delivers 'very smooth clean prints' and 'superior accuracy and detail.' Its advertised 600mm/s print speed is frequently validated, with owners noting print times are significantly reduced compared to other FDM printers. The multi-color capability is a major draw, providing 'stunningly vibrant and vivid prints.' However, performance consistency is a recurring concern. Owners report issues with bed adhesion, requiring adjustments, and frequent clogging, particularly with PETG, which necessitates time for cleaning. While generally capable of handling various filaments, some users struggle with mixed material prints requiring different temperature settings. The ACE unit's filament drying function is effective but contributes significantly to overall noise.

The Anycubic App enables remote control and one-click printing, features that many owners appreciate for convenience. However, the accompanying slicer software receives mixed reviews. While it incorporates 'the best components of all the other slicers,' some users find it less intuitive or challenging to connect directly to the printer. Specific issues include the AI monitor defaulting to 'off,' potentially leading to failed prints unnoticed. Direct PC connectivity is often problematic, forcing reliance on USB drives. While the printer supports Wi-Fi, consistent recognition by a PC or use with mesh networks is not universally reported. Firmware updates are regular, indicating ongoing product development and refinement.

Priced around $500, the Kobra S1 Combo is often seen as a 'good bang for your buck' and a 'great bargain,' especially given its multi-color and high-speed capabilities. Many owners replace more expensive printers with this model, finding it exceeds expectations. Reliability, however, is a point of contention. Several users report receiving 'dud' units or experiencing significant problems early on, such as catastrophic clogs or motor grinding. While Anycubic's customer service receives consistent praise for addressing these issues promptly – often by replacing units or sending parts – the initial inconsistency impacts the product's out-of-box reliability. When functional, units perform well, with some exceeding 'thousands of hours' of printing.
