Prusa or somebody should produce an in depth MMU video for support materials.
I purchased the MMU 3 for the single purpose to used with support materials. I really believe if an in depth video was produced for this, along with multi-color users, with regard to purge volumes would be very very well received. This should include filaments, settings, examples, and in depth explanations. It would also be very cool to cover printing structurally strong parts with support materials using the MMU.
The current published information by Prusa is not clear, nor direct. I understand the MMU 3 is not ideal for supports after purchasing the unit. Even though Prusa markets is for this purpose. I feel a bit scammed by Prusa. I’ve done a bit of digging regarding this topic, and found a good number of people are frustrated by this topic.
How about it Prusa, show us how’s it done.
Thank You
The MMUs are generally OK for toys and trinkets but no single extruder printer is very good with structural/practical parts. With some support filaments, eg., solubles, although they *can* be used to produce a reasonable cosmetic surface finish the trade-off is that for strength you will need to multiply the purge volumes by 5 - 10 times resulting in excessively expensive parts.
Luckily the multi-head XL does handle this sort of thing well so there is an upgrade path 'though at a higher price.
