Material properties

PETG sheet co-polyester is a lightweight thermo-plastic with a high impact strength and high gloss finish.

Typical applications

Art & sculpture, display, glazing, model making, printing applications, protective screens, products prototypes, sign making.


PETG sheet is supplied with protective plastics film on both sides. This is to prevent from scratch marks.

Laser cutting

As a standard, we leave the protective backing on both sides when just laser cutting is required to minimize heat marks on both sides. You will need to peel this off when you receive your job.

Cut widths & Kerf

As a benchmark, we recommend that minimum cut widths be no smaller than the corresponding thickness of the material. For example, if cutting from 2mm PETG, its best not to allow anything less than 2mm in width. We can go smaller (see cut width image above) but this can make your components quite fragile which might not be suitable for the application. See more on cut widths and Kerf (how much the laser takes away.)

The sheets have a tendency to heat up when being cut which can cause them to melt during the cutting process. Make sure you leave lots of space between each component. 5mm is a safe distance.

Cut edge

PETG laser cuts with a highly polished edge. We achieve this using a high laser frequency (ppi. pulses per inch ) that melts the edge as it cuts. If you look closely at the edge it is not entirely smooth and is made up of lots of tiny vertical lines. This is caused by the pulses of the laser.

The priority cutting bed for PETG are aluminium lamella slats. In some cases (artwork dependent) we will need to use the honeycomb laser bed which can cause minor flashback.

Raster & Vector engraving

PETG is not manufactured for ‘appearance’ engraving specifically but it can be achieved. Our standard setting is a light surface scratching. A small level of contrast will occur – engraved areas will turn slightly glossy. This is not advised on thicknesses below 2mm due to the heat causing the material to warp.

Vector engraving

If you just require vector engraving / scoring and cutting, we leave the protective film on the top surface and engrave though the film into the PETG surface. This helps to protect the top and bottom surface from heat and scratch marks when cutting also. Vector engraving is usually advised over raster engraving for component labelling and identification purposes.

Raster engraving

As a standard we remove the top layer of protective backing when any raster engraving is required. We always leave the paper backing on to prevent any reverse markings when cutting is also required.

When raster engraving is required alongside cutting we need to remove the protective film to to engrave the surface. The downside of this is that the surface is more exposed when cutting. Very slight white heat marks can occur around the edge of the cuts. This is fairly minimal but can be cleaned off with a mild soap detergent and sponge if required.

Deeper engraving

Deeper engraving effects are not advised on PETG. The heat buildup can cause the material to warp making the engraving less consistent.
