Supported Filament Types on the MMU3 - Where is ABS in PrusaSlicer?  

RE: Supported Filament Types on the MMU3 - Where is ABS in PrusaSlicer?

MMU3 has been tested with PETG and PLA,  
ABS Should work, but has not been tested enough to create a profile for distribution.

Hi Joan, hope you are having a great day.

Do you happen to know why the MMU3 may not work with filament types other than PETG and PLA? The reason I ask is because I am looking at my MMU3 and all it does is push filaments in and out the extruder (its just a plain filament push / puller). Why does it matter if the filament is ABS, PTU or anything else. It seems to me they are all pushed and pull the same way so why would it matter?

Just curious.

Thank you.

Hi Rene. 

You are correct that the MMU just pushes the filaments towards the extruder and retracts the filaments from the extruder. the difficulty is between filament on the purge block
Using the PLA Settings with PETG Temperatures PETG is not reliable on the purge block. 

I anticipate if you play with the settings and temperatures you can get ABS or ASA to play nicely with the MMU3 setup. 
TPU Is similar, but the soft filament doesn't push to the extruder filament sensor,, too reliably 
Once it's in the extruder and the inter filament purge is complete printing should be ok. 
to the best of my knowledge Prusa have not said ABS ASA TPU Etc, will not work...   

So have a play, see how it goes for you...

regards Joan

Hey Joan,

My use-case for the MMU2/3 was always along the lines of being able to make prints with supports of dissimilar material, including solubles.  The reason being this would make the supports easier to remove without damage to the model.  The supports can be made closer to the model (less gap) and thus better to help keep thre shape oof the model.

The holy grail would be TPU with HIPS supports, but this looks to be beyond hope.

But today's challenge for me is to make some small objects ideally from ASA, but possibly using HIPS supports.
The objects are PINS for purpose of window furnishings (shutters).
Do you think this is within or without the realms of possibility ?

to be absolutely honest I have not tried ASA on the MMU3, or for that matter hips... 

I have used PLA as support for PETG, and that worked well

Good luck and report back please

Joan
