3D Laser Marking and Engraving Explained
Last updated: May 2026
Short answer: “3D marking” means marking that follows depth, not just a flat plane. There are three levels: (1) the motorized Z axis included on every JPT galvo, which sets focus on parts of different heights; (2) an optional EZCad 3 upgrade that varies focus during the job for ramped and relief work; and (3) a true 3D dynamic-focus head for marking curved and contoured surfaces. Most shops only ever need the first two.
The three levels of 3D marking
1. Motorized Z (included). Every JPT galvo machine ships with a motorized Z axis, which many competitors charge extra for. It sets the focal height precisely, so you can mark parts of different thicknesses and step focus between heights. For flat parts at one focus height, this is all you need.
2. 2.5D dynamic focus (optional upgrade, USD 750). An EZCad 3 software and head upgrade lets the machine vary focus during the job. That unlocks ramped engraving, relief depth on otherwise flat stock, and multi-pass deep engraving.
3. True 3D head (optional upgrade). A Feeltek FR10-F dynamic-focus head (an optional upgrade, around USD 5,500) maps a curved surface so the laser stays in focus across spheres, cones, and contoured parts, true 3D marking. The FR10-F comes in 100 x 100 and 200 x 200 mm field sizes and steers focus in software (LenMark), so it uses no swappable field lens — the focus is moved electronically across the surface instead of by changing lenses.
What each level lets you do
- Motorized Z: stepped parts, correct focus per height, consistent marks across thicknesses.
- 2.5D: depth-varying engraving, relief logos, deep engraving on flat metal.
- True 3D: marking on curved cases, rings, tumblers, and contoured surfaces.
Which machine do you need?
For deep and relief work, more power removes material faster, so a 100W MOPA M7 or higher is the practical starting point. Browse the full fiber laser range. For curved heat-sensitive parts (glass, plastics), see our guide to 3D UV laser engraving on curved objects, and our work on 3D coins and challenge coins.
Frequently asked questions
Is 3D capability included or an upgrade?
The motorized Z axis is included on every JPT galvo machine. The 2.5D software upgrade and the true 3D head are optional add-ons.
What is the difference between 2.5D and true 3D?
2.5D varies focus during the job to create relief on mostly flat parts. True 3D maps a genuinely curved surface so the beam stays focused across it.
Do I need the 3D head?
Only for genuinely curved or contoured surfaces. Flat, stepped, and relief work is covered by the included motorized Z plus the 2.5D upgrade.
What power is best for deep relief?
Higher power removes material faster, so 100W and up is the practical choice for deep or relief engraving.
