In the world of precision manufacturing, laser cutting has become the gold standard for clean, accurate, and efficient sheet metal fabrication. But even the most advanced laser machines can’t fix a flawed design.

A great sheet metal laser cutting design ensures:

  • Accurate results

  • Lower production cost

  • Smoother post-processing

  • Minimal material waste

In this practical guide, Nhat Nam’s engineering team shares key principles for designing laser-ready sheet metal parts that are production-ready from the start.

1. Simplify the Geometry

While lasers can cut intricate details, overly complex shapes:

  • Slow down production
  • Increase the chance of error
  • Add unnecessary cost

Pro Tip: Favor clean lines, rounded internal corners, and avoid ultra-small details unless truly necessary.

2. Design Based on the Material

Not all metals behave the same. For example:

  • Aluminum dissipates heat quickly
  • Stainless steel holds its shape but may require slower speeds
  • Thin mild steel may warp without proper spacing

At Nhat Nam, we help you select the right material and thickness for laser cutting efficiency and final use.

3. Account for the Laser’s Kerf

The kerf (laser cut width) can affect how your parts fit together. It’s usually between 0.1 mm – 0.5 mm depending on the laser and material.

Always adjust your design for kerf, especially in slot-tab assemblies, interlocking parts, or high-tolerance applications.

4. Optimize Cutting Paths

Efficient cut paths = faster jobs and lower costs.
Smart design includes:

  • Nesting multiple parts together
  • Using shared edges where possible
  • Avoiding redundant paths

Our engineers use advanced nesting software to maximize material yield and minimize waste.

5. Manage Heat-Affected Zones (HAZ)

Laser cutting generates heat. Poor designs may suffer:

Warping or distortion

Burn marks on edges

Dimensional inaccuracies

Keep adequate spacing between close cuts, avoid dense hole patterns, and let us simulate HAZ before production.

6. Think Ahead to Bending & Assembly

Laser cutting is often followed by:

Good laser design supports these steps, with appropriate bend reliefs, joint gaps, and finishing clearance built into the model.
