Printing the included shapes with PETG – no go?

Hello there,

 

Today, my Mini arrived. Mounting and calibrating went just fine and the PLA printed stuff I tested just came out awesome.

My question: I can see in th filenames the filament to be used to print the included shapes. Does this mean that, for example, if the filename states PLA that I can not print them with a different filament? 

I loaded PETG, but when I tried to print the boat, I immediately realized that the heating that happened was still at 215 C which I think is not enough for PETG. And I saw that the filament was not sticking properly.

So: I must not use a different filament then the one indicated in the filename?

Any advice would be highly appreciated.

Best

 

Armin

It's better to re slice the models...

Slice for different filament

If you refering to default isb files yes. They sliced with valuea for pla, so for petg you need to download file, alicer and make your own gcode with petg profile.

You can start a print and increase/decrease temps as needed, but there other settings that you cant chnage, so better use slicer and create new files to print

Welcome to the forum

Go with the filament that is in the filename!
Different filament has different print temperature, other settings are also different. So, it won´t work.

And, as Joan said, as soon as you got your printer going, start slicing the models yourself

Good Luck and Have Fun 😊

To be precise, the filament type in the filename has no meaning by itself. What's key is, at what temperature the model was sliced.

If you slice with a PLA profile, it will by default use PLA temperatures and insert PLA into the filename, a PETG profile will use PETG temperatures and insert PETG into the filename, etc. Yet, nothing keeps me from selecting a PETG profile but then change the temperature to 200 degrees. The filename will still say PETG but now PLA will print fine because of the lower temperature. 

Of course, in the real world, I don't see any reason why anyone would do that so it's safe to assume that anything with PLA in the filename will require PLA to print properly, PETG required PETG, etc.
