For cutting, the file must contain machine-readable vector paths. A picture inside a PDF is not enough.

Guide summary
What this helps you decide.
How acrylic behaves when laser cut, which finishes work best, and how to design parts for clean edges and reliable fit.
The aim is practical: better quoting files, fewer production surprises and clearer decisions about when to use instant pricing versus reviewed quoting.
Quote fasterClean DXF, DWG or vector PDF files with real cut lines reduce back-and-forth before production.
Choose process firstMaterial, thickness, finish and tolerance decide whether fiber laser, CO2 laser, CNC router or digital knife is the right workflow.
Review complex workIf the job includes finishing, fabrication, supplied material, photos, unclear scale or mixed services, send it for reviewed quoting.
Practical checks
Before you send the job.
1:1 size
Set drawings at real-world scale and remove duplicate lines, open paths and hidden construction geometry.
Thickness and finish
Confirm material, thickness, side finish, coating and whether you are supplying sheets or need material included.
Review if unsure
Engraving, folds, paint, welding, 3D printing, assembly or unclear files should go through reviewed quoting.
Buyer notes
Acrylic laser cutting depends on grade, thickness and visible edge expectations.
Acrylic is one of the strongest CO2 laser materials, but the job still needs correct grade, clean vector files, realistic thickness expectations and clear finish notes. Perspex is commonly used as a trade name for acrylic, but unknown clear plastic should not be assumed to behave like acrylic.
Confirm acrylic grade
Cast acrylic, extruded acrylic, coloured acrylic, frosted acrylic and mirror acrylic can behave differently. Supplied acrylic should be reviewed before relying on a quote.
Confirm thickness
Thickness changes edge appearance, heat behaviour, detail limits, handling and whether CO2 laser or CNC router is the better process.
Protect visible faces
If one side is visible, say so. Protective film, masking, handling marks and face orientation should be discussed before production.
Check holes and slots
Small holes, slots near edges and tight mating parts may need review because acrylic can crack during installation if design expectations are unrealistic.
Avoid unknown plastics
Do not send unknown clear plastic as acrylic. Unknown plastic, polycarbonate, PVC and mixed plastics need review or exclusion.
Plan finishing
Flame polish, sanding, bonding, bending and paint are separate decisions and should not be assumed inside a cutting-only quote.
Avoid these mistakes
Small setup mistakes create quote delays.
Check 1
Do not call every clear sheet Perspex without confirming material.
Check 2
Do not put screw holes too close to acrylic edges without review.
Check 3
Do not assume routed and laser edges look the same.
Check 4
Do not hide face-side expectations until after production.
What to send
Good quoting starts before the file upload.
The best quote request combines a clean file with the commercial details that production needs: material, thickness, quantity, finish expectation, deadline and whether the part is a sample, one-off, repeat batch or component in a larger job.
If any of those details are unknown, reviewed quoting is the better path. It gives the team a chance to check the file, ask the right questions and prevent a fast estimate from being mistaken for a production-ready decision.
Quote readiness
Use the guide as a pre-flight check, not a replacement for production review.
Good guidance reduces wasted quoting time, but it does not remove the need to check files, materials and finish expectations. If the work has supplied material, mixed processes, visible presentation faces, tight fit-up, customer-specified hardware or unclear scale, the safest quote path is still a reviewed quote before production acceptance.

Common questions
Answers before production starts.
Can I upload a PDF for cutting?
Yes, but only if it is a vector PDF with real cut lines at the correct scale. A JPG, screenshot or photo saved as a PDF is still an image.
Which files are best for instant pricing?
DXF and DWG files are preferred. Vector PDF can work when it contains real vector cut paths.
When should I ask for review instead of instant pricing?
Ask for review when the job has unclear geometry, supplied material, finishing, fabrication, engraving, folds, assembly or tight production requirements.
