Problem with MMU prints
Hi, I am having problems with multi material prints where parts of a model that are of a different colour that butt up to another part break away when printed. Adding a modifier and giving them a different infill to cover the join is a bit slow when you have lots of bits butted up and beam interlocking only works with internal parts and not external.
When I have a model of something that has arms, legs, feet and other bits that are of a different colour even though I am using the same filament they sometimes break off at the place where the colour changes. Are there any settings that I am missing , or am I just asking too much of the slicer. Any help or ideas would be appreciated.
That looks like a basic 2D print - how much thickness is there for adhesion between the adjacent perimeters? You may need to print thicker and key internal layers.
For specific help save your project as a .3mf file
Files > Save Project as
Zip the .3mf and post it here. It will contain both your part and your settings for us to diagnose.
Cheerio,
RE: Problem with MMU prints
Hi, thanks for replying. Yes it is 2d, it's a keyring and it is 5mm thick, I don't really want to print any thicker as it would up the printing time but I suppose I could. It would be good if you could explain about keying internal layers as the mmu printing puts the stated number of perimeters around all the different coloured parts which means that they are not keyed together where they join. I have attached the model, hope this helps.
