· PET-G Thermoforming and Heat Treatment Safety
Is PETG safe to thermoform and heat treat?
I don't know, sorry. Just had some other comments. It is a higher temp material but still well below boiling and you can definitely mold it and unlike many materials is very similar to PLA in that you can thermoform it just fine. I'm 80% sure that will work just fine as I've heated PETG and formed it before. However it's "softening temp" is 20 or 30C hotter than PLA (I forget which) and PLA already just about burns you when thermoforming against skin - PETG will definitely cause serious burns. So you'll need to wear some kind of fabric covering the surface to thermoform to and where gloves for the person doing the forming.
It seems to me if you can heat it to 230C (or whatever the temp is) to melt it then any gasses created at 90C should be fine!
I know nothing about heat treating PETG. I dont' think that will be necessary since PETG has such a higher melt temp. You don't have to worry about it melting in a car in direct sunlight on a 40C (105F) day. Not an issue. Cars can get to 60C but not the temps necessary to soften PETG (or nGen or CPE).

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
