Laser marking,
material by material.
The substrate decides the process. Stainless steel and titanium are annealed, anodized aluminum is ablated, bare aluminum is etched, and plastics foam or carbonize depending on the grade. Each page below covers the process we run on the JPT M7 MOPA fiber laser, what the mark looks like, Data Matrix readability, post-processing, and how to call the mark out on a drawing.
- 01ANNEAL
Stainless Steel
Black annealed marks with no material removal. Passivation-safe marking for surgical instruments, implants, fasteners, and fluid-handling parts.
303 · 304 · 316/316L · 17-4 PH · 400 series
Process and drawing notes - 02ABLATE · ETCH
Aluminum
White-on-black marks on dyed Type II and Type III hardcoat anodize. Frosted etch, dark MOPA marks, and deep engraving on bare 6061 and 7075.
6061 · 7075 · 2024 · 5052 · Type II · Type III hardcoat
Process and drawing notes - 03ANNEAL
Titanium
Dark annealed marks and interference colors at low heat input. Non-intrusive marking for implants, instrument sets, and fatigue-critical aerospace hardware.
CP Grade 2 · Grade 5 Ti-6Al-4V · Grade 23 ELI
Process and drawing notes - 04FOAM · CARBONIZE
Plastics
Dark or light marks formed in the polymer, with no ink or label. Grade-dependent: resin, colorant, and filler decide contrast, so jobs start with a sample coupon.
PEEK · Ultem/PEI · Nylon · ABS · PC · Delrin · additive grades
Process and drawing notes
Eleven materials in one table.
Carbon and alloy steel, tool steel, brass and copper, technical ceramics, coated and painted parts, and laser-markable label stock are covered in the material marking guide, alongside the four materials above. It lists the primary process, expected contrast, and Data Matrix readability for each substrate.
Marking types and equipment are under capabilities, and verification is described under quality: every serialized code is read back and graded before shipment. When the part itself cannot take a direct mark, a laser-marked asset tag or UID label carries the code instead.
