How each alternative compares
ACMER S2 20W Diode Laser Engraver
The ACMER S2 20W Diode Laser Engraver trades the iCube Ultra’s enclosed safety and metal marking for raw cutting power. It features a 20W diode module, which is stronger than the iCube’s 12W diode, making it better for thicker wood and acrylic. You get air assist for cleaner cuts, but you lose the Class 1 housing and the IR module for metal. This unit is open-frame, so you must wear protective goggles. It fits hobbyists who prioritize speed and budget over safety enclosures and metal engraving capabilities.
xTool F2 15W Diode & 5W IR Laser Engraver
The xTool F2 15W Diode & 5W IR Laser Engraver offers significantly more metal marking power than the iCube Ultra. It pairs a 15W diode with a 5W IR module, compared to the iCube’s 1.2W IR. This allows for faster, deeper metal engraving. It includes a camera for precise alignment and maintains a portable, enclosed form factor. However, it lacks the iCube’s auto-focus and built-in exhaust fan. You get a lighter, more mobile unit ideal for professionals who need quick metal work and batch processing on the go.
xTool F2 Ultra 60W MOPA and 40W Diode Laser
The xTool F2 Ultra 60W MOPA and 40W Diode Laser is a professional-grade dual-laser system that far exceeds the iCube Ultra’s power. It combines a 40W diode for fast wood cutting with a 60W MOPA laser for precise color metal engraving. This is a desktop unit with a larger footprint, not a compact portable box. You gain immense cutting speed and color marking capability, but you lose the beginner-friendly, plug-and-play simplicity and the small form factor. It suits users who need high-volume production and advanced material control.
LaserPecker LP2 Plus Portable 10W
The LaserPecker LP2 Plus Portable 10W focuses on portability and speed rather than enclosed safety. It features a 10W diode laser, which is less powerful than the iCube’s 12W diode for cutting, but offers high engraving speeds. It is a handheld-style device, making it much lighter and easier to move around than the iCube’s desktop unit. You give up the Class 1 enclosure, auto-focus, and air assist. This option fits users who prioritize weight and mobility for small batch work and prototyping over large bed size and safety features.
Creality Falcon2 Pro S 40W Enclosed Laser Cutter
The Creality Falcon2 Pro S 40W Enclosed Laser Cutter provides substantial cutting power with a 40W diode laser, significantly higher than the iCube’s 12W. It includes auto-focus, air assist, and a camera, offering more advanced features than the iCube’s basic auto-focus. The unit is a large desktop machine, much bigger and heavier than the iCube’s compact design. You gain the ability to cut thicker materials safely in an enclosed space, but you lose portability and the IR module for metal marking. It suits makers who prioritize cutting thickness and safety.
ACMER S2 Pro 36W Diode Laser Engraver
The ACMER S2 Pro 36W Diode Laser Engraver offers a larger working area and higher power than the iCube Ultra. It features a 36W diode module, which is nearly three times the power of the iCube’s 12W diode, allowing for faster cutting of thicker materials. It includes air assist for better cut quality. However, it is an open-frame machine, requiring protective goggles, and lacks the IR module for metal marking. You trade the iCube’s enclosed safety and metal capabilities for raw power and a larger bed for detailed diode engraving tasks.
