How to Minimize the Cost of Laser Cutting Services (Updated for 2026)

Last updated on September 2nd, 2026 at 01:28 pm

Laser cutting is a fast and flexible way to produce custom sheet metal parts, but the cost can vary significantly from one design to another.

Laser cutting cost is influenced by material, thickness, total cut length, pierce count, part geometry, material utilization, quantity, and any secondary operations required after cutting.

The good news is that engineers can often reduce part cost without changing how the finished component functions. The key is understanding which design decisions actually affect manufacturing time and material usage.

It also helps to work with a full-service sheet metal fabrication shop with multiple cutting and forming capabilities. A part designed with laser cutting in mind may sometimes be produced more economically using CNC punching, or with a combination of both processes.

What Determines the Cost of Laser Cutting?

For custom sheet metal parts, laser cutting cost is not determined by part size alone. Two parts with the same outside dimensions can require very different amounts of machine time and material.

Important cost drivers include:

• Material type and thickness
• Total length of the cutting path
• Number of individual pierces
• Number and size of holes, slots, and cutouts
• Part size and sheet utilization
• Order quantity
• Small or fragile features
• Edge-quality requirements
• Tolerances and inspection requirements
• Deburring and other secondary operations

Because these factors interact with one another, reducing laser-cutting cost is usually about optimizing the complete design rather than changing one feature in isolation.

Laser Cutting vs. CNC Punching

We frequently review designs that contain features that could be produced using our CNC punch press instead of, or in addition to, laser cutting.

Laser cutting is highly flexible because the cutting path is programmed digitally. This makes it well suited to prototypes, low-volume production, complex profiles, and designs that may change between revisions.

CNC punching uses physical punch-and-die tooling. When the required tooling is already available, punching can be an efficient way to produce repeated holes or other features. It can also create formed features that a laser cannot produce, such as certain louvers, embossments, knockouts, and other punched forms.

If custom punch tooling is required, the tooling cost and lead time may not make sense for a small quantity. At higher quantities, however, the economics can change because that tooling cost is distributed across more parts.

The decision also does not have to be laser cutting or punching. Some parts benefit from both processes. For example, the laser may cut the main profile and complex geometry while the punch press creates louvers or other formed features.

How to Reduce Laser Cutting Costs

When laser cutting is the right manufacturing process, several design decisions can affect both cutting cost and the total cost of the finished sheet metal part.

Choose the Thinnest Material That Meets the Design Requirements

Material thickness affects raw material cost, weight, cutting conditions, forming requirements, and other downstream operations.

Thinner material can sometimes reduce cost, but material thickness should always be driven by the functional requirements of the part first. Strength, stiffness, durability, thread engagement, forming, welding, and the operating environment may all determine the minimum practical thickness.

If the design does not require a particular thickness, discussing the application with your fabricator can help identify whether another readily available thickness would satisfy the requirements more economically.

Choose a Commonly Stocked Material

Material specification can affect both price and lead time before the laser ever begins cutting.

Specifying an unusual alloy, temper, thickness, or sheet size may require a special material purchase and could introduce supplier minimums or additional lead time.

When the application allows it, choosing a material and thickness that is already in stock can simplify sourcing and help avoid unnecessary material purchasing costs.

Reduce Unnecessary Cut Length

The laser has to travel along every cut edge in the design. As total cut length increases, so does the amount of machine time required to produce the part.

Review decorative cutouts, complex internal profiles, long vent patterns, and other nonfunctional geometry to determine whether they provide enough value to justify the additional cutting.

This does not mean every irregular profile is expensive. A visually complex outside profile may require less machine time than a simple rectangular panel containing hundreds of internal features.

Reduce Unnecessary Pierces

Cut length is only part of the equation. The number of individual cutting features also matters.

Each separate hole, slot, or internal cutout typically requires the laser to begin another cut. A panel containing hundreds of small holes or ventilation slots can therefore require considerably more machine time than a similarly sized panel containing only a few openings.

Common examples include:

• Large perforation patterns
• Rows of ventilation slots
• Decorative cutouts
• Large quantities of small holes
• Repeated internal profiles

If a design requires a high number of repeated features, ask whether CNC punching or another manufacturing approach could be more economical.

Design With Material Utilization in Mind

Material can represent a significant portion of the finished part cost, so efficient sheet utilization matters.

Fabricators use nesting software to arrange parts on sheet stock, but the geometry of the part still determines how efficiently those parts can be nested.

Factors that can reduce material utilization include:

• Large or unusually shaped blanks
• Long, narrow parts
• Dimensions that barely exceed a common sheet size
• Required grain direction
• Cosmetic surface requirements
• Low quantities that leave significant unused material

Engineers generally do not need to create their own production nests. Instead, consider whether noncritical overall dimensions or orientation requirements are unnecessarily restricting how the fabricator can arrange parts on the sheet.

Consider Part Size Relative to Available Sheet Sizes

A small dimensional change can sometimes have a large effect on material utilization.

For example, a part dimension that slightly exceeds the usable area of a common sheet size may require a larger sheet or prevent multiple parts from nesting efficiently together.

This does not mean designs should be forced into arbitrary dimensions. But when an overall dimension is flexible, discussing material utilization with the fabricator before finalizing the design can reveal opportunities to reduce scrap and cost.

Avoid Extremely Small or Fragile Features When They Are Not Functional

Small holes, narrow webs, closely spaced cutouts, and thin projecting features can require additional consideration during laser cutting.

Depending on the material and thickness, these features can create concentrated heat, unstable geometry, part tip-up, or additional programming and handling requirements.

If a small feature is essential to the design, keep it. If it serves no functional purpose, simplifying it may improve manufacturability and reduce risk.

Tolerance Considerations for Laser-Cut Parts

Laser cutting can produce precise features, but tighter drawing tolerances do not automatically cause the laser to cut more slowly.

The cost impact comes from the additional manufacturing and inspection controls that may be required to reliably satisfy a restrictive tolerance.

Depending on the requirement, tighter tolerances may involve:

• Additional process control or setup
• More detailed inspection
• Additional measurement time
• Secondary machining or other operations
• Increased risk of rework or rejected parts

Apply Tight Tolerances Where They Affect Function

Tolerances should reflect how the finished part fits and functions.

A mounting feature that establishes the position of another component may require more dimensional control than a ventilation opening or noncritical outside edge.

It is also important to distinguish between dimensions established during flat laser cutting and dimensions that depend on later operations such as forming, welding, hardware insertion, or finishing.

When a dimension is functionally critical, identify it clearly on the drawing so the fabricator can evaluate the best manufacturing and inspection approach.

Specify Edge Quality Where It Matters

Laser-cut edge condition depends on material, thickness, cutting parameters, assist gas, feature geometry, and other process conditions.

Most fabricated parts also receive an appropriate deburring operation, but some applications may have additional edge requirements.

Identify those requirements when an edge:

• Mates closely with another component
• Remains exposed as a cosmetic surface
• Will be welded
• Receives adhesive or a seal
• Serves as an electrical contact surface
• Has another function that depends on its condition

Avoid adding special edge-finish requirements to every cut surface when they are not necessary for the finished product.

Heat and Part Stability During Laser Cutting

Laser cutting introduces localized heat into the material. On thin sheet or parts with concentrated cut geometry, that heat can sometimes affect part stability.

Long narrow features, closely spaced cuts, large perforated areas, and repeated cuts concentrated in a small area may require additional attention.

The fabricator can account for these conditions through cutting strategy, sequence, nesting, and part-retention methods where appropriate.

Rather than adding tabs or microjoints directly to the customer CAD model, provide the finished geometry and allow the fabricator to determine whether temporary retention features are needed for production.

Consider Quantity When Choosing a Cutting Process

The most economical manufacturing method can change with quantity.

For prototypes and small quantities, laser cutting often provides significant flexibility because new part geometry can be programmed without dedicated cutting dies.

As quantities increase, other approaches may become more attractive. Repeated features may be candidates for CNC punching, and the cost of dedicated tooling may become easier to justify when distributed across a larger production run.

Providing realistic prototype and expected production quantities during quoting helps the fabricator evaluate the process based on the complete project rather than a single order.

Look at Total Fabrication Cost, Not Just Laser Time

Laser cutting is often only the first manufacturing operation.

A laser-cut blank may still require:

• Deburring
• Countersinking
• Tapping
• Press brake forming
• Hardware insertion
• Welding
• Grinding or cosmetic finishing
• Powder coating, plating, anodizing, or another finish
• Inspection
• Assembly

Because of this, the design change that saves the most laser time is not necessarily the change that produces the lowest-cost finished part.

For example, splitting a part into multiple simpler laser-cut pieces could reduce cutting complexity but add forming, welding, grinding, inspection, and assembly labor.

A good DFM review considers the entire manufacturing route.

Choose ASM for Laser Cutting, CNC Punching, and Complete Sheet Metal Fabrication

Approved Sheet Metal combines laser cutting with CNC punching, forming, hardware insertion, welding, finishing, and assembly capabilities, allowing us to evaluate the complete manufacturing process when quoting a custom part.

Our proprietary louver tooling, for example, provides an efficient way to incorporate specific formed louver features into compatible sheet metal designs without requiring new custom tooling for every project.

If you are trying to reduce the cost of a part, send us the complete 3D model and dimensioned drawing rather than optimizing only for laser cutting. We can review the material, geometry, cutting process, forming, hardware, welding, finishing, and other requirements to identify potential DFM opportunities.
