Buying Guide
Laser Power and Material Compatibility
Laser power determines what materials you can cut and how fast you can engrave. The S1 2500mW model handles thin wood, leather, and acrylic for light craft work. The S1 3500mW offers more headroom for thicker cuts and faster passes. The S2 12W laser module with 72W total system power cuts up to 15mm paulownia wood and 12mm black acrylic with multiple passes, making it ideal for deeper projects.
If you mostly engrave on coated metal, ceramics, or dense acrylic, the higher power S2 is worth the investment. For occasional cutting of thin plywood and MDF, either S1 model will serve you well.

Precision and Spot Size
Fine detail work demands a small laser spot and high positioning accuracy. The S1 models offer 0.01mm repeatable positioning accuracy, which is excellent for reproducing intricate patterns and small text. The S2 goes further with a refined 0.08×0.08mm laser spot and up to 0.01mm positioning accuracy, ensuring clean edges on photos and detailed artwork.
If your projects involve high-resolution images or micro-text, the S2 delivers noticeably crisper results. For basic signs and crafts, the S1 still provides reliable precision. The XTOOL D8W Wireless Bidirectional Scan Review offers another perspective on precision-oriented engravers.
Software and Ease of Use
ACMER Studio software is free and beginner-friendly, featuring AI tools that turn text prompts or photos into engraving designs. All three models also support LightBurn and LaserGRBL, giving you flexibility as your skills grow. The S1 machines arrive 99% preassembled with just a 1-minute laser head installation, while the S2 requires slightly more assembly but remains straightforward.
For those new to laser engraving, the S1 models are the easiest to set up and start using immediately. The S2 offers more advanced settings for experienced users. Both platforms are compatible with Windows, macOS, and Linux. For a deeper look at software options, check our creality 10W engraving machine review.
Workspace and Expandability
The S1 models feature a compact 130×130mm working area, ideal for small crafts and tight desks. The S2 offers a spacious 300×300mm workspace, letting you handle larger signs, layered art, and multi-piece layouts. The S2 also supports optional rotary modules, risers, and air assist, expanding its capabilities to cylindrical objects and taller workpieces.
If you plan to grow your engraving business, the S2 provides room to scale. For home hobbyists with limited space, the S1’s small footprint is a major advantage. For more on expandable systems, see the creality falcon A1 10W review.
