Design notes

PETG 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. Vector engraving is favored over raster engraving and intricate details are not recommended.

Typical uses

Point of Purchase Displays - Flat wall components - Product Dispensers - Food container - Bicycle Helmets - Prosthetic devices

Environmental info

PET can be recycled in some areas.

Adhesives, joints & fastenings

PETG can be bonded using WELD-On #3 or WELD-ON #4.

Does anyone have recommendations for cleaning spray paint off of a PETG stencil?

You could try alcohol blending solution, but I'd recommending trying on a scrap of PETG first.

Does anyone have experience creating crease or fold lines on PETG? Can a sheet of 0.5mm stock take a fairly clean 90* bend? Does a vector engraving line make a reasonable score mark for folding, as it does woth cardstock?

Hi Jonathan,
We've had one customer find heavy vector (Red stroke) engraving was a little too deep to create a live hinge in the 0.5mm. Then they found medium vector (Green stroke) engraving on 0.5mm was a more suitable depth. We'd suggest to start there.

Dayma,

Thank you for your suggestion. As per your recommendation, I made a prototype using medium vector engraving on 0.5mm PETG. The line folds easily away from the cut side of the surface. Unfortunately, if the line is folded toward the cut side, the material snaps right in half.

I found that a scrap of the PETG material could handle hundreds of back-and-forth fold cycles without breaking. Unfortunately, medium engraving does not allow for a back-and-forth fold, and becomes fragile with repeated folding. Would light engraving likely be any better? Or should I be looking for other ways to create folded lines in your PETG material.

Hi Jonathan,
Yes when you vector engrave a line, it only works to bend it one way. I'm not sure if a light engraving line will give you a better result to bend both ways. You could try dashed engraving or cutting lines, that help the fold occur but still keep the strength for it not to snap?

Is it possible to fuse/adhere clear silicone rubber to PETG and laser cut?

Hi Thomas,

Do you mean joining them before we laser cut them? Unfortunately we aren't able to join any materials together before we laser cut them. If you'd like to join them together after they're laser cut, you could possibly do that. We'd recommend asking your local hardware store about which fasteners/glues would be the most appropriate.

Thanks.
