Why is PETG opted out on UM printers?

[X-Type 2]

Hi 

 

Why have Ultimaker decided not to support PETG?

 

It is a very commonly used material and Ultimaker supports a lot of materials, but not PETG. So I am curious as to what the reasoning is behind opting PETG out.

 

Thanks

Because there are no profiles for it. Making a set of profiles for an Ultimaker printer is a lot of work, requiring a lot of test prints for all combinations of printers, nozzles/printcores, "intents" and qualities. Until very recently there was no Ultimaker-branded PETG, so no single "PETG" to test with (and no incentive to spend money on the profiles, because it would not result in sales of Ultimaker-branded materials, I guess).

 

The UM S5 and S3 support PETG now, and I think I saw on github that the UM 3 will receive profiles for it too in the next version of Cura. I am not sure about the UM2 family.

That's not a reasoning behind opting PETG out, it's the effect of having opted PETG out.

 

I have the S5 with latest firmware and it does not offer PETG. I checked it before posting my question.

That is perhaps a misunderstanding.  An up-to-date Cura is required to use PETG.

PETG support has been available since Cura 4.8, currently 4.9.1. If you select PETG in a current Cura, its profile is transmitted to the printer with the print job.

The printer firmware itself supports everything and nothing, so to speak.
