Laser vs. traditional engraving.

The short version: for durable marking on metal, laser is faster, finer, and more permanent. For very deep relief in soft metal, rotary still has a place.

Traditional engraving is mechanical: a spinning carbide or diamond bit cuts material as it traces the design. The bit has to press into the workpiece, which limits fine detail, how hard a metal it can work, and how delicate a part it can hold without deforming.

Laser engraving is thermal: a focused beam either ablates material (a cut-in engrave) or grows a thin surface oxide (a flush anneal or color mark). Nothing touches the part, nothing wears out mid-job, and the beam turns corners far tighter than any bit.

How they compare.

	Laser	Rotary / traditional
Contact	None — beam only	Physical bit presses into the part
Fine detail	Excellent — photos, tiny fonts, QR codes	Limited by bit width
Hard metals	Titanium, hardened & tool steel — no problem	Hard on bits; slow or impractical
Delicate / irregular parts	Safe — no force applied	Risk of slipping or deforming the piece
Deep relief in soft metal	Possible, multi-pass, slower	Strong — a genuine advantage
Surface-flush marking	Yes — annealing, corrosion-safe	No — always removes material
Color on metal	Yes — MOPA oxide color marking	No (paint-fill only)
