This study focuses on the development of a laser engraver with multi-axis clamp, a
specialized machine designed to perform precise and intricate marking on a variety of
materials. Traditional laser engravers typically operate on a two-axis platform, limiting
their ability to efficiently and accurately engrave curved cylindrical, or irregular-shaped
workpieces. To address these limitations, this project integrates a multi-axis clamping
system that securely holds and rotates the material, allowing the laser to engrave on
multiple planes without the need for manual repositioning. The main components of the
system include an infrared laser, a stepper motor-controlled chuck, and a robust mechanical
frame made from galvanized steel. An Arduino microcontroller and specialized control
software manages the movement of the motor and the delivery of the laser, ensuring
precise, automated operations. The prototyped engraver was designed, constructed, and
evaluated in terms of marking depth, rotation time, and engraving time. This study
demonstrates that adding a multi-axis clamping feature to a laser engraver could
significantly enhance its capabilities, allowing for greater flexibility, reduced manual
intervention, and more efficient production of engraved products. The results suggest

potential applications in industries requiring personalized marking, prototyping, and small-
scale production of components.
