Material freedom without heat.
Best when one precise, non-contact process must handle advanced alloys, ceramics, glass, composites or mixed materials.
Start with material integrity and geometry.Process comparison
The best process
depends on the part.
Laser, wire EDM, CNC milling and waterjet are all valuable production technologies. The useful question is not which process wins overall—but which one protects the material, reaches the geometry and delivers the required economics for this component.

Side-by-side overview
Six processes.
Different strengths.
This is an application-level guide—not a substitute for trials. Machine type, material, thickness, geometry, settings and required quality can change the result substantially.
| Criterion | Finecut micro abrasive waterjet | Ultrafast / short-pulse laser | Conventional laser | Wire EDM | CNC milling | Conventional waterjet |
|---|---|---|---|---|---|---|
| Core mechanism | Fine particle erosion | Pulsed material ablation | Thermal melting or vaporisation | Electrical spark erosion | Mechanical cutting tool | Water and abrasive erosion |
| Material range | Virtually any material, including mixed stacks | Broad, but source and material specific | Strong in selected metals; material dependent | Electrically conductive materials only | Broad, limited by tooling and machinability | Virtually any material |
| Thermal influence | None from the cutting process | Low and highly localised, process dependent | Heat-affected zone is inherent | Local thermal layer and possible recast | No thermal cutting zone; cutting heat still managed | None from the cutting process |
| Tool contact / force | No solid tool contact; low process force | No contact | No contact | No contact | Direct tool contact and cutting forces | No solid tool contact; higher jet forces |
| Typical geometry | Fine 2D contours, bevels and synchronized 5-axis access | Micro-features, thin sections and specialised patterns | Fast 2D profiles and some 3D systems | Ultra-precise through contours and tapers | Full 3D features where the tool can reach | 2D profiles and production bevel cutting |
| Finepart reference capability | ≈0.2 mm kerf; typical ±10 µm in 3X and ±25 µm in 5X | System and application specific | System and application specific | Often selected for tolerances tighter than ±10 µm | Machine, tool, feature and material specific | Designed for larger kerfs and looser tolerances |
| Preparation | CAD/CAM path and application parameters; limited hard tooling | Optics, focus and process development can be specialised | Programming, gas and material-specific parameters | Conductive setup, wire path and submerged process | Programming, tools, fixtures and tool changes | CAD/CAM path, abrasive parameters and fixturing |
| Strongest fit | Advanced materials, material integrity, high mix and complex precision profiles | Very small features, thin material and specialised high-value parts | High-speed sheet-metal production | Ultra-tight precision in conductive materials | 3D pockets, surfaces, threads and prismatic features | Large-format cutting and thicker stock |
The figures and descriptions are indicative. Finecut tolerance depends on material, thickness, geometry, axis configuration and quality target. Final feasibility, edge quality and cycle time are established on the actual application.
Where each process earns its place
Choose for the
dominant requirement.
Strong process selection is usually a portfolio decision. Finecut often complements existing CNC milling, laser and EDM capacity rather than replacing every operation.
Extremely localised energy.
Strong for very fine features, thin material and specialised microprocessing where the laser–material interaction is well developed.
Start with feature size and material absorption.Fast sheet-metal throughput.
Strong for production cutting in compatible sheet materials where speed matters more than eliminating thermal influence.
Start with volume, sheet thickness and edge condition.Ultra-tight conductive precision.
Strong for very tight tolerances, smooth through-cuts and thick conductive stock where recast can be accepted or removed.
Start with conductivity and tolerance.True 3D material removal.
Strong for pockets, threads, surfaces and features that require a defined cutting tool—provided access and cutting forces are acceptable.
Start with feature access and fixturing.Large parts and thicker stock.
Strong for flexible, non-thermal cutting at larger scale where a wider kerf and conventional production tolerance are appropriate.
Start with envelope and thickness.Choose Finecut when
The part must stay unchanged.
- Heat-affected zones or recast layers are unacceptable
- The material is non-conductive, brittle, hard or layered
- Cutting forces or tool wear compromise the part or economics
- One platform must handle changing materials and high-mix work
- Fine contours, bevels or synchronized five-axis access are required
Choose another process when
A different strength dominates.
- You need tolerances substantially tighter than Finecut can verify
- You need pockets, threads or machined surfaces rather than a cut contour
- Very high-volume sheet cutting makes conventional laser the economic choice
- Large-format or very thick stock favours conventional waterjet
- The feature is smaller than the practical Finecut kerf
A complementary production route
Combine processes.
Remove the constraint.
Finecut can create the net shape or protect critical material zones; CNC or EDM can then finish only the features that need their specific strengths. This can reduce hard tooling, contact forces, thermal exposure and total setup effort.
Finecut + CNC
Cut the near-net profile without heat or high force, then machine pockets, threads or datum surfaces.
Test the net shape ↗Finecut + W‑EDM
Use Finecut for mixed materials, cold contours or five-axis access; reserve EDM for the tightest conductive features.
Read Finecut vs W‑EDM ↗Finecut + laser
Separate applications by thermal sensitivity, material mix, feature scale and production volume instead of forcing one process to do everything.
Explore materials ↗Proof before product
Compare on the
actual component.
The most credible comparison uses your drawing, material and quality target. Finepart will identify the uncertainties and establish measurable evidence through a test cut.
