What’s Included

• RA3 rotary unit

• MagSwap™ chuck, roller, sphere, and ring attachments

• Fast‑swap magnetic mounting system

• Optional Chuck Kit and Roller Extension Kit for batch production

Best Use Cases

• Engraving tumblers, mugs, and bottles

• Full‑wrap engraving on vases and cylindrical objects

• Jewelry engraving (rings, bangles, ornaments)

• Batch production for small business customization

• Complex shapes like spheres and irregular items

Considerations

• Smart automation features (3D preview, auto recognition, LiDAR mapping) are only supported on P Series machines

• F Series machines (galvo lasers) support MagSwap™ and mechanical upgrades but not automated modeling functions

• Requires riser base for use with P2/P2S

The RA3 is ideal if you want maximum flexibility and speed in rotary engraving, especially for businesses handling diverse shapes and batch orders. It’s a major upgrade over the RA2 Pro, with larger capacity, faster setup, and smarter automation.
