If you explicitly choose your model material for Support/raft Base, then it will eliminate the layers of interface material mixed into your supports. Leaving the material for Support/raft Base as "Default" will allow interface material to be used for building your support base, which can cause weakness and may allow supports to break. Just a handy tip.

I've been playing with doing this since ModBot made a similar video on an IDEX printer, and it can be great. BUT, when the geometry gets more curvature, the PETG and PLA bonding issues start to show. The flat surfaces are the best case scenario. More organic models will start to experience failures as the support and interface layers develop inconsistencies. Then there is the clogging. Temperature differences of the nozzle from PETG and PLA will start clogging the nozzle. But I believe your high purge values really help with this. Thanks for that, I will use that in the future. One other thing I prefer, is to remove the purge tower. I had a few failures when the purge tower failed and got dragged over to the model.
@boehserenkel

Curved geometry should be better with tree PETG support then?
@mikejackson9585
8 ай бұрын
@boehserenkel The problem is that the PETG doesn't stick to PLA and vice versa. So, the general rule of thumb would be to minimize the layers of different material, that way, there are fewer chances to fail. So, a flat surface is supported with only 1 material change. But with curvature, that number of different materials goes up a lot, increasing the chance of one of the layers failing to adhere. On suggestion for printing models with lots of curvature would be do the entire support structure and interface layer in one material and the model in another. That way, the support is only sticking to the same material and the same with the model. However, PLA & PETG have significant differences in temperature requirements. You'll have to pick a comprised bed and nozzle temp for both. Constantly changing temperatures will likely lead to issues.

It can be. Since PLA and PETG don’t stick together, that also means that they don’t mix together either. The key is to purge as much as possible when it changes materials, so that you’re minimizing how much cross contamination there is. But depending on the model, some parts may end up being weak. This model I used to be a demonstration because of its flat bottom surfaces. But yes, the legs would be quite weak in this case.

Yes, but I wouldn’t disable the prime tower unless I absolutely had to regain that bed real estate. Having it print to another object before going back to the model is preferable to simply going back to the model right after being over the dump. It helps to regulate pressure in the nozzle. Also, that wiping motion that it makes at the dump is far from flawless. The prime tower can help make sure that any extra material is pulled away from the nozzle before it goes back to printing on the model. If I’m only printing with one material, I’ll absolutely disable the prime tower. But on multiple material prints, I’ll always use it.
