3DP'g of TPU/PLA on the U1

[Kurt The 3D Printer GUY!!]

Dang - I know my printer is Quite new - but, Ouch - I had no idea I would have such a difficult time trying to find info/tutorial/video on how to assign 2 head to 2 parts - where I built my own Supports (for PLA) - and have the Model (to print in TPU). 

CoPilot was giving me GARBAGE Links to videos that were no longer available. One was by 3DP Nerd - and I really wanted to see that one. Also other deadlinks.

Went to Google for a similar search - it gave me directed info. - semi-step by step - but, some of the options it suggested - I could not find them in the slicer. 

It's interesting to see HOW Close the SnapMaker Slicer is to the Elegoo Slicer - although - I know they are BOTH Forks of Orca!

I ended up Winging it - I got it Sliced - am printing it NOW - I thought FOR SURE I would have MORE PRoblems - as PLA should NOT Stick to TPU. But, It's doing the PRime tower - AND it's printing the part - and essentially NO Problems so far...

So far it has NOT Failed - and I am about 45 min into the print - it's a total of 1H 24m. 

I honestly Expected a FAIL by now - either of Prime tower - or of the Part! But, it's STILL PRinting! 

Of course - it's a SMALL Test...

Sorry for the Typos & wrong caps - am doing this fast - as it's getting late - and I gotta get my Act together (dinner/lunch/Bfast prep) - yada yada yada...

Anyway - I am attaching the project file - for THOSE Folks that have the U1 - and want to Peek at it!!!

Uhhhh… I’ve had PLA stick to tpu! Who told you they don’t stick?

[3D Printing Tips and Tricks]

Here’s a sample… the hinges and the top surface that nozzles fit into are all tpu…

This was a Prior thread on here - maybe TWO of them!

The one was about a guy who did this kind of accordion or bellows type print w/TPU & PLA. I gotta go find that and then repost it here.

I found it!!!!!

His initial posting:
    This one is cool as it has many applications.
    Functional Print Fridays on youtube has explored using PLA as support material for TPU. Yesterdays video showed how he created a bellows structure out of tpu. Pretty         cool and definitely need a tool changer or a dual hotend machine.

Cool video, definitely want to try this. 

I have an idea for a lantern style bellows With PLA top and bottom caps, and the TPU embedded in those with a flange.

Also want to do a better PTFE stop for my AMS HT than what he came up with.

Yeah Bryan - I found that to be a Fascinating Video that guy did. I wonder if there is a way to get directly in touch with that Dude from the video. 

Definitely keep us posted on your Lantern Style thing...

My valentines day card used a mix of filaments.  I also designed it (completely in Prusaslicer) so that the PLA and TPU interlocked

Also screen shot shows where in orcaslicer you can play with generated supports I think

Bryan - FYI - I TRIED to do what that guy did - but, it was a FAIL! 

I really, REALLY NEED to find out WHY!!!!!
