Many years ago someone told me they were combing PLA and PETG on their dual extrusion 3d printer and having really good success with it. Since then I have wanted to try it out but either forgot or didnt have a machine capable. Today we will take a look at how well this does or doesnt work.

Try using the support for just the 1 interface layer so the head doesn't have to change too often. I create three parts in Simplify3d, the part, the support with the same material, and the interface layer, to minimize how much of the print would need changing the print head. I have the support part as an independent part so I can use 1 wall with no bottom and a low infill.

One trick that can save you a lot of time is to use the support material only in the top interface.

At least in Bambu Studio laminating software, I don't know about the other laminating programs. Let me explain.

You print a part in PLA and you are going to use PETG as support material. In the laminating program you just activate the PETG support material in the top interface. This causes PLA to be used as support material except for the part that touches the part.

This avoids having to make unnecessary filament changes. It only makes such a change when it reaches the top support interface.

Greetings to all.

if you want to separate support easily but don't have IDEX printer, you can try pausing the printer during the print and add a layer of glue stick right at the interfacing layer. I do this by adding a post processing g-code in CURA to stop and beep when the support roof is printed. However this is only suitable for design with simple geometry, but still useful in a pinch.

Fantastic episode Daniel. Always enjoy watching or better put learning.

This is really cool, the results were absolutely amazing!

This is really cool! Multi colored prints are awesome but showing how an idex can be used like this is awesome, my supports never come out this nice

THIS opens up a new world to me!!!
This is the first real reason to wanting a dual material 3D printer!!!
Absolutely awesome!
All my new printers will have dual material ability

I discovered this by mistake and now it's my go-to. The Bambulab AMS makes life easy

Mate, this is a game changer for those who use ultimakers and struggle to keep their PVA supports dry. I’m going to try this out straight away!

Was JUST researching this earlier. Thanks for this!

Really interesting
Combination of PLA with ABS supports and vice-versa would be amazing to see next.

We have one IDEX printer in our farm and that never occurred to me. I will try it out. Thank you, as always.

That is very cool. Being able to use a less expensive filament (like a basic or recycled) PLA or PETG for supports would be much less expensive than specialty filaments. I also like the idea of using an idex machine to stitch together different filaments to make something combined, such as something stiff with a flexible joint. 😃
