Real vector geometry
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.
A plain-English guide to materials that suit laser cutting, materials that need CNC routing or knife cutting, and materials to avoid.
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
Material choice starts with the laser process.
Laser cutting is not one universal process for every sheet material. Fiber laser is the metal path. CO2 laser is the acrylic-led non-metal path. Some plastics, foams, rubber, vinyl and composite sheets belong on CNC router or digital knife workflows instead of laser.
Fiber laser materials
Mild steel, stainless steel and aluminium are the main fiber laser materials, with brass, copper, Corten, galvanised and coated metals reviewed by grade, thickness and finish expectation.
CO2 laser materials
Acrylic and Perspex are the main CO2 laser materials. Selected paper, card and light sheet materials can be reviewed, but unknown plastics must be treated carefully.
Do not laser PVC or vinyl
PVC and vinyl materials are not laser cutting candidates. They should be routed, knife cut or excluded depending on the product and safety requirements.
CNC router alternatives
ACM, PVC foamboard, MDF, plywood, HDPE and thicker acrylic can often belong on CNC router pages instead of laser pages.
Digital knife alternatives
Foam, rubber sheet, gasket material, vinyl, cardboard and flexible materials can often be better handled by digital knife workflows.
Supplied material
Customer-supplied material should be reviewed because grade, film, condition and unknown additives can change the correct process.
Avoid these mistakes
Small setup mistakes create quote delays.
Check 1
Do not assume clear plastic is acrylic. Unknown clear plastic must be reviewed.
Check 2
Do not ask for CO2 laser cutting on metal parts.
Check 3
Do not ask for fiber laser cutting on acrylic letters or Perspex panels.
Check 4
Do not choose by thickness only; material chemistry and finish matter.
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.
