I can confirm HIPS works as interface support for ABS, but I'm not sure yet my HIPS profile is perfect...



It is still a better result than without a different material as interface support... For the small story, the profile I used for HIPS is ASA, as there is no profile for HIPS yet in BambuStudio nor in the X1C firmware... I may try the same with ABS profile later on...

Tires test print resumed today, following some mail exchanges and advisory provided by the resin manufacturer.
I launched a modified versions of both front and rear tires, to ease the printing.

Few hours later...


The rear is a clear fail and I still do not understand why. I'm going to increase the supports to see if it changes something...

The front however is looking good :-). And until now, all my attemps to pull a front tire turn in a fail...


I've modified the rear slicing, and change somethin on the tire model. Let's see in a few hours...

The front tyre looks nice.

Some progress...

The front tire is nice. And better, I can reproduce it :-)




That being said, I did not succeed to pull a rear tire yet...
Launched another different test. We'll see later...

Another test, another fail...


This is so frustrating... I decided to give up for today... It seems at some point the print splits or is not raised enough or too quickly...

The good news in this is that the filter funnel i ordered is perfect to empty the VAT... I still need to find the way to put the VAT tank in place without making any mess around, but this is so much easier than before, that it is almost comfy to do...


Maybe I won't bother too much to change resin anymore...

You could make your rear tires in 2 parts like for the big bear?

There is no reason to do this: it printed once, and my problem is that I can't reproduce this...
Further I'm not even sure it would work to glue the two parts... This is already highly experimental, no need to add more experimentation on top of this...

It was a suggestion.  And I 'm sure you'll find a solution.

Time to get back to some tire topics!

I received today two rolls of filaments for some tests I intend to do:
- Colorfabb Varioshore Foaming TPU
- Recreus Ninjaflex TPE 60A

I decided to launch a test right away with some tires printed in foaming TPU. The profile was supploed by Colorfabb on Printables, and the only few things I need to understand is what infill to use to get a proper foam tire.


I set the first attempt to 25% infill, and we will see the result tomorrow... Depending on the result, I'll increase or decrease the infill. The tire itself is super simple, and overhang should not be an issue in anyway with a foam tire. The original profile provided doesn't have any retractation, I will need to find out about that as well... First indications will be tomorrow...
