Dire Printing quality on Test Parts

[B0M0A0K]

Yes, I do. Infact, this prototyping work is being done in PLA to get the print right before making the final print in PETG.

Secondly, do you have an AMS on your P1? Saw you have the Combo. That’s good.

If you can share that model, I can setup a print profile for you that will guaranty the quality you’re looking for. Since you are going to print the final model in PETG right?

@B0M0A0K

Yes, that’s right (the PETG final). How would I get the model to you?

I just PMed you. I’ll provide you the details later in the day once I got your file, I need to head out pickup my family member.

So, here you set your PETG and PLA. The 3MF file in the same place where you uploaded. PLA and PETG don’t stick to each other after cooled down, so you can increase the density of the interface support.

I use the PLA as interface for the PETG - the red one for you to see.

How it was done?

The trick here is that you select any of these 3 filaments even you don’t have it.

Then at the Support area (Advanced turned on), pick that as interface. The software will automatically adjust the setting.

Then go back to your filament selection pick back your PLA.

This is to trick the software thinks that you are using Support filaments.

You can do this vice versa opposite as well.

Astonishing detail and assistance. Thank you so much for taking the time to look at this, it’s hugely appreciated. Will try and look at this again tomorrow but about to head out on a road trip for a week, so will comment once I have had a chance to look at it.

I have learnt so much just from posting this one topic and reading the responses. Just amazing!

Hi Folks. OK, so there’s a word I use every now again, but it’s not common.

The word is “Flabbergasted”.

I got some time to look at the file and instruction set sent by @kip yesterday. To be honest, I don’t completely understand what’s going on here, but I put my best “parrot” face on and just copied the instructions as they were supplied.

I used the same eSun PLA+ as the support and my Generic PETG as the main material. Then I tried to print the model.

This is where the word “flabbergasted” comes in.

This is the print as it came off the textured plate, with the supports in place.

These supports came off easier than any support I have ever used. A little finder pressure and “pop”, off they came.

This is the resultant print.

… so, Flabbergasted.

I need to go over this again and fully understand what happened and why a support acts so differently. There was a half support spool in the box with the P1S-Combo, but not having used it before I put it aside for a rainy day.

As I mentioned, I am off on a week long road trip Monday, so may not get a chance to do a deep dive into this process, but it’s a generational difference that I will definitely be using again. It has helped me move forward with this project in a meaningful way.

Again, and especially @kip I can’t thank you guys enough for your help and knowledge transfer on this subject.

Yea- his advice was very slick, I had read about using mis-match materials as support to take advantage of the lack of bonding between them, but had never tried it- and definitely didn’t think of using it in your application.

Was a clever suggestion for sure!

Sometimes, support settings can be tricky. Have you tried adjusting the support density or using a different support pattern? Reducing the support contact Z distance might help make the supports easier to remove without affecting the print surface as much. Also, ensure your supports only touch areas that really need it. If those changes don’t help, it might be worth experimenting with different filament brands or tweaking your retraction settings.

I wanted to ask a question that’s directly related to the solution @kip provided.

Firstly, this method of printing dissimilar filament has been a complete game changer for my rapid prototyping work. I have now used it on several other prints, all with significantly improved results.

I want to be able to move on and print with ABS, for stronger parts. It’s my first experience with printing ABS and I have just had a delivery of Bambu Basic ABS (Black) to play with. I tried to re-run the print job above only to get a warning from Bambustudio about not being able to print with filaments that require large variations in their ideal print temperature.

This doesn’t seem unreasonable, but I am trying to decide how to address it.

If I am unable to mix PLA+ with ABS then should I just default to “support filament”, or will this also result in the error message.

Any suggestions please?

ABS and ASA uses HIPS filament for support.
