Five services, one shop
Each service below lists what it includes and its key limits. Click any one for full details, or send a drawing and we’ll tell you which service fits.

Laser Welding
Our core service. Pulse-shaped LASAG lasers make deep, clean welds with very little heat, so thin, crack-prone and heat-sensitive parts stay intact.
- Hermetic seam & seal welds
- Spot and tack welds
- Dissimilar-metal joints
- 360° circumferential welds
- Handheld welding for large parts
- Tooling & mold repair
Laser Marking
Permanent marks for traceability and identification, applied with a MOPA laser that can also make color marks on stainless steel.
- Part & serial numbers
- 2D Data Matrix & barcodes
- Aerospace part marking
- Medical UDI marking
- Color marking on stainless
- Logos & panel graphics

Laser Cutting & Drilling
Precision cutting and fine-hole drilling, from micro holes in thin stainless to profiles on large sheets.
- Profile cutting
- Micro & fine-hole drilling
- Trimming & slotting
- Mesh and thin-foil work
CNC Machining
High-precision 4th-axis milling and CNC turning, coordinated with our laser work so parts don’t bounce between vendors.
- Weld fixtures & tooling
- Weld-joint preparation
- Prototype parts
- Production components
3D Printing
Three printers for three kinds of jobs: detailed functional parts, high-temperature PEEK-class polymers, and large one-piece parts.
- Functional prototypes
- Carbon-fiber composite parts
- PEEK, PEKK, PEI, PPSU, PPS
- Large-format parts
- Jigs, fixtures & brackets
