Carverall Z12 $1299.00 Desktop fiber laser engravers have finally become affordable enough for small workshops and serious hobbyists — but choosing the right one is still tricky. The Carverall Z12 enters this crowded space with a broad configuration range spanning 20W to 60W MOPA, industrial-grade components, and pricing that significantly undercuts most competitors in the fiber laser category.
What sets the Z12 apart is its modular approach: you’re not locked into a single power level or laser type. Whether you need basic serial-number marking for a small parts business or advanced MOPA color engraving for jewelry and premium customization, the Z12 platform has a configuration for you. Prices start at around $1,280 for the 20W standard fiber version and scale up to $2,850 for the top-tier 60W MOPA, making it one of the most accessible entry points into professional fiber laser technology.
This review breaks down the Z12’s specs, real-world performance, pros and cons, and how it stacks up against two major competitors — the Sculpfun G20 and the ACMER PM.

The Carverall Z12 is a galvo-fiber laser engraving system designed primarily for metal and selected plastics. It uses an industrial-grade fiber laser source combined with a high-speed galvo scanner and optimized field lens system, delivering rapid beam movement, precise positioning, and consistent energy delivery.
A standout feature across all models is the electric Z-axis lifting system, which ensures fast, precise height adjustment and stable focusing for different materials and thicknesses. The machine also supports dual lenses, 360° rotary engraving with the MD18 rotary chuck, and external foot pedal control.
