Our Verdict
I recently spent time putting the DAJA S4 through its paces to see if this compact fiber laser could actually handle professional-grade engraving tasks. After testing it across various surfaces including stainless steel, gold, and leather, the machine consistently delivered crisp, precise results that honestly surprised me for its size.
Performance & Build Quality
The build quality of the DAJA S4 feels robust and intentional, weighing in at 17kg with a solid chassis that minimizes vibrations during high-speed marking. Its fiber laser technology is remarkably efficient, allowing for deep, clean etching at speeds up to 10,000 mm/s without compromising the 0.01mm accuracy requirement.
Day-to-Day Experience
Setting up the software was straightforward, as it integrates well with standard industry tools like LightBurn on Windows systems. Once calibrated, the workflow becomes incredibly smooth, making it easy to swap between materials and power settings for repetitive tasks.
This is an excellent tool for custom jewelry makers, product designers, and small-batch manufacturers who need reliable, portable metal marking capabilities.
Final Thoughts
The DAJA S4 earns a perfect 5/5 rating for its reliability and the sheer professional quality it brings to a workspace. While the $3,999 to $4,999 price tag is a significant investment, it is an essential piece of hardware for any business serious about scaling their engraving production in 2026.
