Printing Supports to Save Time and Money !

I show how to use 3D multi material printing support structures from a different, normal printing material for the different types from easy PLA and PETG to engineering filaments like PA12-CF, ASA or PPA.

It would be very nice if we could discuss there everything about Stirling engines, 3D printing and more, thank you very much Baptiste.
Support structures are part of many 3D prints, but they are often an annoyance.
The supported surfaces often look bad, they are not dimensionally accurate, and removing the supports leaves ugly marks.
With delicate models and internal supports, removing them without damaging the print is very difficult—and sometimes even impossible.
High-tech engineering filaments can barely be separated and are a waste of expensive printing material.
With the widespread accessibility of multi-nozzle printers, it is now possible to use different materials for the print and the supports.
With the right combination, you can achieve cleaner prints with less post-processing and less waste.
There are filaments made specifically for support structures.
However, these are usually expensive and have to be bought separately.
That is why I only use standard printing filaments that I already own.
This is cheaper and more practical.
I also don't want to submerge my models in water or other liquids, as this can reduce their strength and make post-processing harder.
I would like to thank Flashforge for providing me with their new Creator 5 Pro for extensive testing.

In principle, all of this also works with an AMS.
The most well-known material combination is PLA with PETG.
I have achieved very good results with this and noticed no problems at all.
Using PLA for the model and PETG for the supports, as well as the other way around, produces smooth surfaces and was always easy to remove.
Especially with very fine models, this makes the work much easier and delivers far better results.
For ASA and ASA-CF, I use PETG as the support material.
This works very well, but it bonds a bit more strongly, so you have to be somewhat careful when removing it.
If the bond with the support interface is too weak, standard unreinforced ASA is especially prone to warping.
I also support PA12-CF and other nylon filaments with PETG, although warping occurred on my extreme test part.
With ASA as the support material for nylon, adhesion is slightly better and warping is reduced, depending on the model.
With the fiber-reinforced prints for my thermoacoustic Stirling engine, removing the rock-hard supports was a pain, even on the outside.
PPA also prints very well with PETG support structures.
They are easy to remove, and the contact surfaces look clean.
My first impression of fiber-reinforced PPA is very good, and I am looking forward to the upcoming stress tests.
I hope there was a suitable material combination for you here, and that it works just as well for you as it did for me.
As always, I really look forward to your criticism, suggestions, and opinions in the comments, on Discord, or at ownenergy.org.
