Design NotesPETG has high Impact strength and is reasonably flexible. It can be formed with and without heat although tight bend radii could result in splitting and stress marks on along the folded edge. It has a low melting point so intricate cutting detail is not recommended.
The manufacturers tolerance for the thickness of the materials is as follows:
|Material thickness||Possible Range|
|0.020” / 0.5mm||0.018" - 0.022”||0.4 - 0.6mm|
|0.040” / 1.0mm||0.035" - 0.043”||0.9 - 1.1mm|
Engraving PETGDue to its low melting point PETG does not engrave very well. Line engraving is favored over area engraving and intricate details are not recommended. There are 3 types of engraving possible with laser cutting. Area engraving, line engraving and a combination of both.
Line engraving is like a really shallow cut. To achieve this effect the stroke color to red with RGB values of 255, 0, 0 and set the stroke style to a width of 0.01 mm. The laser beam follows along the red lines that you have in your design and marks the surface of the material. The result is crisp but it can be a time consuming technique if you have a lot of small details like text.
Area engraving is great it you need to mark a large area on the surface of the material. To specify area engraving set your shapes to have a fill color of black with RGB values of 0, 0, 0. The way this engraving is performed is like an old dot matrix printer except instead of dots of ink it uses pulses of the laser beam. This is a surface finish not deep enough to be used for pocketing or inlays. The depth of the engraving ranges between 0.1-0.5mm.
Using a combination of both engraving types typically gets the best result. Set your shapes to have a fill color of black with RGB values of 0, 0, 0, the stroke color to red with RGB values of 255, 0, 0, and set the stroke style to a width of 0.01 mm. The line engraving causes the laser beam to trace around the edges of the engraved areas making them more crisp and bringing the details to life.
To achieve a 3D form PETG is typically folded or layered. It can be folded without heat although tight bend radii could result in splitting and stress marks on along the folded edge. The best way to dictate a fold area is to use a dashed cut line. Typically a etched line will disrupt the surface tension of the material and cause it to snap rather than to fold.
