There is no reliable universal laser-cutting price per part. PartFab calculates the price from the selected material and thickness, sheet utilisation, setup, cutting and piercing time, quantity and delivery. For an exact UK price, upload a clean 1:1 DXF, DWG or SVG and select the material, thickness and quantity.
In brief: the part's overall size is only one input. Two parts with the same footprint can have very different prices when one uses thicker material, contains more holes, wastes more sheet or is ordered as a one-off.

How laser cutting cost is calculated
A laser-cutting quote is normally built from five cost blocks:
- Material: the sheet consumed by the nested parts, including spacing and unusable offcut.
- Machine time: cutting, piercing and movement between contours.
- Setup: drawing checks, CAM programming, nesting and machine preparation.
- Process costs: assist gas, consumables, power, handling and inspection.
- Commercial costs: overhead, margin, delivery and any minimum order charge.
A useful simplified model is:
Estimated job price = material + setup + (machine rate × production time) + handling + margin
This explains the main inputs, but it is not the PartFab quoting formula. The live quote uses the current material, process and commercial settings for the uploaded part.
Material is usually charged from the sheet area allocated to the job rather than the net weight of the finished part. Efficient nesting can therefore reduce cost, while an awkward profile may leave offcut that cannot be used elsewhere.
How much does laser cutting cost per hour or minute?
PartFab does not quote a customer-facing flat price per laser hour or minute. Machine time is only one input: the final price also depends on material, sheet utilisation, setup, piercing, quantity, handling and delivery.
A generic hourly rate cannot answer what a specific part will cost. Uploading the drawing lets the quote use the actual cut paths, pierces, material and thickness instead of a broad time allowance.
How to estimate laser cutting time
A basic time estimate starts with geometry:
- Add the length of the outside profile and every internal hole, slot and cutout.
- Divide that cut length by the expected cutting speed for the selected material and thickness.
- Count closed contours and add the relevant pierce time for each one.
- Add travel between contours, lead-ins, lead-outs and machine movements.
- Add loading, unloading or handling where the supplier's model includes them.
The simplified relationship is:
Production time ≈ cut length ÷ cut speed + pierce time + movement allowance
Cutting speed and pierce time vary with the selected material and thickness. A CAD perimeter alone is therefore not enough for a precise estimate; the quote also needs nesting, contour order, lead-ins and the applicable process settings.
What affects the price of laser cutting?
| Price driver | Why it changes cost | What the buyer can control |
|---|---|---|
| Material | Different grades have different sheet and processing costs | Specify the least costly grade that still meets the requirement |
| Thickness | Thicker sheet generally cuts and pierces more slowly | Avoid excess thickness unsupported by the design load |
| Cut length | Longer profiles keep the machine cutting for longer | Remove non-functional detail |
| Pierce count | Each closed hole or cutout needs a start cycle | Reduce unnecessary holes and decorative cutouts |
| Nesting | Poor utilisation increases material allocated to each part | Permit rotation or combine compatible parts where appropriate |
| Quantity | Setup is divided across more parts | Compare practical batch quantities |
| Tolerance and finish | Demanding requirements can slow production or add inspection | State only functionally necessary requirements |
| Lead time | Urgent work can disrupt planned production | Use a flexible delivery date when possible |
Material and thickness
Mild steel is commonly economical for general fabrication. Stainless steel and aluminium may cost more as raw material and can require different gas or process settings. Grade matters as well as the generic material name, so state the exact specification required.
Thickness affects both material mass and production speed. Moving from thin sheet to thick plate can increase cost more than its area suggests because the laser cuts more slowly and each pierce takes longer. Do not reduce thickness without checking strength, stiffness, deflection, wear and joining requirements.
PartFab's laser cutting service supports selected mild steel, stainless steel and aluminium from 1–15 mm, subject to material and drawing geometry. The online quote shows the supported combinations available for the uploaded part.
Geometry, cut length and pierces
The machine follows every cut contour. A plain profile with few holes is usually faster to process than a similarly sized panel with many cutouts. Small features can also be impractical when their size approaches the material thickness or when heat concentration threatens cut quality.
Delete duplicate lines and overlapping contours before quoting. They create ambiguity and can require manual drawing repair. Use closed profiles and remove title blocks, dimensions and construction geometry from the cutting file.
Quantity and setup
Drawing checks, CAM programming and machine preparation happen even for one part. One-off work therefore carries a larger setup cost per part. At higher quantities, that fixed work is spread across the batch, although total material and production time still rise.
Compare only the quantities you could genuinely order. A lower unit price is not a saving if excess stock becomes obsolete.
Why can laser cutting seem expensive?
The invoice covers a controlled manufacturing process, not just electricity for the laser source. Industrial equipment, extraction, maintenance, software, assist gas, trained operators, material handling, inspection and scrap risk all have to be recovered.
A small one-off bracket may spend little time under the beam but still needs its drawing checked, nested and programmed. Minimum charges prevent that preparation and administration from being sold at a loss. Laser cutting can nevertheless be economical for flat profiles because it avoids dedicated hard tooling and lets multiple designs share a sheet.
How to reduce the cost of laser-cut parts
Start with the changes that preserve function:
- Use a standard material and thickness. Unusual grades may require special purchasing or leave costly remnants.
- Remove non-functional detail. Decorative slots, dense perforations and intricate edges increase cut length and pierces.
- Use sensible feature sizes. Avoid tiny holes or narrow webs unless the function requires them.
- Order practical batches. Compare quantity breaks so setup is spread without creating unwanted stock.
- Allow efficient nesting. If grain direction or cosmetic orientation does not matter, say so.
- Specify realistic tolerances. A general laser-cut profile should not inherit machining tolerances by default.
- Submit clean files. A 1:1 DXF, DWG or SVG with closed contours reduces drawing-repair work.
- Plan the whole fabrication. Include bending, tapping, welding, finishing and delivery; the cheapest flat blank may not create the cheapest finished part.
Do not merge holes into slots or change thickness simply to shorten cutting time unless the revised geometry still meets the engineering requirement.
How to budget for a laser-cutting project
Build the budget from known project requirements:
- Fix the material grade, thickness and finish requirement.
- Prepare the final cut geometry and remove duplicate or open contours.
- Choose the quantity you actually need.
- Include any secondary operations and delivery requirements.
- Upload the drawing and use the returned price for the project budget.
Avoid budgeting from machine time alone. Material, nesting, setup and other production costs can be more important than beam-on time.
What to send for an accurate quote
Prepare these inputs before starting a quote:
- a 1:1 DXF, DWG or SVG in millimetres;
- one part design per file;
- closed, non-duplicated cut contours;
- material grade and thickness;
- quantity for each part;
- any required tolerances, grain direction or visible-face requirement;
- delivery postcode and target date;
- notes for secondary operations not represented by the flat profile.
The fastest route to an exact price is to upload your drawing for an instant quote. The system can cost the actual geometry rather than relying on a generic rate per minute or metre.
Frequently asked questions
What is the price of laser cutting?
The price is the sum of material, setup, production time, process costs, handling and the supplier's margin. A simple job may be covered by a minimum charge; complex geometry, thick material or low quantity can cost much more. Only a drawing-based quote can price the actual part accurately.
How is laser cutting cost calculated?
Suppliers calculate material from nested sheet usage and production from cut length, cutting speed, pierces, movement and setup. They then include assist gas, consumables, labour, overhead and margin. The exact formula and machine rate vary by supplier, so generic calculators provide estimates rather than binding prices.
How much does laser cutting cost per minute?
PartFab does not publish a flat customer price per laser minute because it would not describe the final part price. The quote accounts for the drawing geometry, material, thickness, setup, piercing, quantity and delivery rather than multiplying one generic minute rate.
Why does quantity reduce the unit price?
Programming, drawing checks, nesting and machine setup are largely fixed for a batch. Ordering more parts spreads those fixed costs across more units. Material and cutting time still increase with quantity, so the unit price falls by different amounts depending on the job.
Do I need a DXF, DWG or SVG for a quote?
For an accurate automated quote, provide a clean 1:1 DXF, DWG or SVG in millimetres with closed cut contours. A sketch, PDF or overall dimensions cannot reliably describe every cut length, hole and nesting constraint needed to calculate production time and material use.
