Laser Cutting vs Laser Engraving
Compare cutting through material and decorating its surface by process, artwork, depth, materials and suitable applications.
Quick answer
Laser cutting moves the beam along vector paths and passes through the material to create separate shapes, holes and outlines. Laser engraving removes or changes only part of the surface to create text, logos, patterns or images. A single product can combine both processes, such as an engraved acrylic sign that is also laser cut to its final shape.
Key differences
- Laser cutting passes completely through the material.
- Laser engraving changes only the surface or a controlled depth.
- Cutting normally uses vector lines.
- Engraving may use raster images, filled vector shapes or lines.
- Cutting creates separate shapes and internal holes.
- Engraving creates visible details without separating the material.
- Many products use cutting and engraving in the same production job.
What is laser cutting?
Laser cutting uses a focused beam to follow an outline and penetrate through the material. The process separates a finished shape from a larger sheet.
It can create external outlines, internal holes, slots, tabs, decorative patterns and interlocking parts.
What is laser engraving?
Laser engraving removes, melts, darkens or alters the upper surface of a material without cutting through it completely.
It is commonly used for names, logos, photographs, serial numbers, decorative patterns and product information.
Laser cutting and engraving compared
Laser Cutting
The laser follows a thin vector path and passes through the full material thickness.
- Creates external shapes
- Produces holes and internal cut-outs
- Useful for signs, boxes and components
- Requires clean closed vector paths
- Material thickness affects edge quality
Laser Engraving
The laser creates visible surface detail without separating the whole material.
- Adds names, logos and patterns
- Can reproduce selected photographs
- Creates recessed or colour-changed areas
- Suitable for serial numbers and QR codes
- Appearance depends on the material

Which process suits different products?
Acrylic Sign
Engrave the wording or logo, then cut the acrylic to its final custom shape.
Wooden Name
Use cutting to create the name outline and engraving to add patterns or smaller details.
Gift Box Insert
Cutting produces slots and shapes, while engraving adds instructions, branding or product identification.
Metal Nameplate
Engraving or marking creates the information. Metal cutting usually requires different industrial equipment.
Personalised Tumbler
Surface engraving removes or changes the coating without cutting through the tumbler.
Architectural Model
Cutting creates walls and components, while engraving adds lines, textures and assembly references.
Vector cutting vs raster engraving
How the laser reads the artwork
Vector cutting
The laser follows a mathematical line from point to point, similar to drawing with a pen. This is efficient for outlines, holes and detailed cutting paths.
Raster engraving
The laser moves back and forth across an area in horizontal rows, similar to an inkjet printer. It turns on and off to reproduce filled graphics, text and photographs.
Vector engraving
A vector line may also be engraved at lower power instead of being cut completely through. This is useful for score lines, fold guides and fine outlines.
What is laser scoring?
Laser scoring creates a shallow line without cutting through the material. It is useful for fold guides, assembly marks, layout references and decorative linework.
Scoring is normally faster than engraving a filled area because the laser follows only the vector path.
Understanding laser kerf
Kerf is the narrow amount of material removed by the laser beam during cutting. Although the beam is focused, it still has a measurable width.
Kerf affects pieces that must fit together. Slots, tabs and interlocking components may need dimensional compensation.
Loose fit
A slot may become too large when kerf is not considered.
Tight fit
Artwork can be adjusted so components press together more firmly.
Material variation
Actual sheet thickness can vary from the advertised measurement.
Test fitting
A small test piece is recommended before producing a complete interlocking design.
Suitable materials
Acrylic
Can be cut into smooth shapes and engraved to create a frosted appearance.
Wood
Can be cut and engraved, although grain, resin and glue content affect the final result.
Paper and card
Suitable for detailed cutting, scoring and decorative patterns when heat marks are controlled.
Leather
Can be engraved and cut when the material composition is safe and suitable.
Coated metal
Surface coating may be engraved or removed, but cutting normally requires specialised metal-cutting equipment.
Selected plastics
Only identified, laser-safe plastics should be processed.
Material thickness and cutting quality
Thicker materials generally require slower speed, more laser power or multiple passes. This may increase edge darkening, melting, taper and production time.
Cutting quality also depends on focus, airflow, protective film, material consistency and machine capability.
Why engraved colour varies
Laser engraving does not normally add printed colour. The visible result comes from the material itself.
- Clear acrylic often becomes frosted or white
- Wood may become darker or lighter
- Coated metal may reveal the base metal
- Anodised aluminium may produce a pale or contrasting mark
- Selected plastics may darken, lighten or change texture
Product samples should be tested when the final shade is critical.
How to prepare laser-cutting artwork
Use vector paths
Supply cutting lines as editable vector artwork rather than low-resolution images.
Close all shapes
Open paths may leave incomplete outlines or unwanted connections.
Remove duplicate lines
Duplicate paths may cause the laser to cut the same line more than once.
Use thin strokes
Hairline or clearly identified vector strokes are preferred for cutting paths.
Outline fonts
Convert fonts to curves to prevent substitution or missing-font problems.
Check small parts
Tiny internal pieces may fall through the machine bed or become too fragile.
How to prepare engraving artwork
Use solid black artwork
Solid black is commonly used to indicate fully engraved areas.
Prepare photographs carefully
Images may require grayscale conversion, contrast adjustment and dithering.
Avoid tiny text
Very small text may fill in or become unreadable on textured materials.
Increase contrast
Subtle grey differences may not reproduce clearly on every material.
Separate process layers
Keep cutting, scoring and engraving elements on clearly labelled layers.
Confirm engraving direction
Reverse engraving may be used on the rear of transparent acrylic for a smooth front surface.
Recommended artwork colour coding
Colour coding can help separate production operations, although the final colours should always be confirmed with the production team.
- Red hairline: cutting path
- Blue hairline: scoring or line engraving
- Solid black: raster engraving
- Separate named layers: alternative professional workflow
These colours are production instructions and do not necessarily represent the final product colour.
Minimum detail and safe margins
Small details near a cut edge may weaken the finished piece or become difficult to reproduce.
Text, logos and engraving should remain a safe distance from cut edges, holes, corners and narrow bridges.
The appropriate distance depends on the material, thickness, product size and artwork complexity.
Common artwork mistakes
Low-resolution cutting file
A JPEG outline cannot provide the same clean tool path as editable vector artwork.
Duplicate paths
Overlapping lines may cause repeated cutting and excessive heat.
Open corners
Small gaps may prevent the cut piece from separating cleanly.
Text not outlined
Missing fonts can change the design or cause production delays.
Very thin bridges
Narrow connections may break during cutting, cleaning or use.
No process separation
Unclear artwork may cause engraving lines to be cut or cutting paths to be engraved.
Common production issues
Burn marks
Heat, smoke and resin can darken the surface near cut or engraved areas.
Melted edges
Some plastics may soften, distort or form a raised edge.
Uneven engraving
Warped materials or inconsistent focus can create variations in engraving depth.
Material movement
Lightweight sheets may move when small parts are released.
Smoke staining
Smoke may settle on the material surface without suitable protection and extraction.
Incomplete cutting
Material variation, thickness, focus or insufficient power may leave uncut areas.
Material safety
Unknown materials should not be laser processed until their composition has been confirmed.
Some plastics and composites can produce toxic or corrosive gases. Suitable extraction, filtration and fire monitoring are essential during production.
How to choose the correct process
Choose cutting when
The material must be shaped, separated, slotted or produced with internal openings.
Choose engraving when
The product needs names, logos, photographs, serial numbers or decorative surface details.
Combine both when
A custom-shaped product also requires branding, instructions or decorative features.
Request testing when
The material, thickness, coating, fit tolerance or engraving colour is uncertain.

Frequently asked questions
Can a laser cut and engrave in the same job?
Yes. Engraving is normally completed first, followed by cutting the final outline and internal openings.
What file type is best for laser cutting?
Editable vector files such as AI, PDF, EPS or SVG are generally preferred, subject to the production workflow.
Can a photograph be laser engraved?
Yes, on suitable materials. The image normally requires grayscale adjustment, contrast improvement and dithering.
Does laser cutting leave a gap?
Yes. The beam removes a narrow amount of material known as kerf.
Why are my laser-cut edges dark?
Heat, smoke, resin, material composition and cutting speed can darken the edge, especially on wood and paper products.
Can every plastic be laser cut?
No. The exact plastic must be identified because some materials are unsafe or produce poor cutting results.
