Look at my awesome MMU prints!
Here's some of what I've been printing lately:
Rosie the Multimaterial Skunk ( https://www.thingiverse.com/thing:2640493 ). Printed for a friend. 0.15mm layers, it came out beautifully.
These are trophies for an upcoming event. I printed the base and top parts separately, and the tops were printed flat and assembled. Bases are ABS, and tops are PLA. With the MMU I could have printed the whole thing as a single print (if I used only ABS or only PLA, because ABS and PLA won't fuse), but that would have been an absurdly long print with tons of support. 0.25mm layers.

Those trophies look great. Copies really maximize the color changes.
Have you played with wipe to infill or wipe to object yet ?

Re: Look at my awesome MMU prints!
Thank you for the pics!! They look great.
What is your overall impression of the MMU2? Is it a work in progress that will get better or is it strictly experts only?
Re: Look at my awesome MMU prints!
They look great. I really like the trophies.

Re: Look at my awesome MMU prints!
nice, but that first print really stinks (skunk joke) now ive got pepe le pew suave lines stuck in my head.
glad to see you stopped printing cubes for awhile.
I have a Prusa,therefore I research.

I used wipe to infill on the skunk. I didn't use it on the trophies because the bases are printed with a transparent ABS, and the top parts only have color on the top and bottom layers (so no color changes where there's infill).
Re: Look at my awesome MMU prints!
This is just a test print, but I'm posting it to prove that it's possible to mix TPU and PLA in the same print.
The ends are white PLA squares 2mm thick, and the middle is a white TPU (98A) square 1mm thick. It's not really obvious from the photo, but the PLA and TPU are interlocked for better strength. Printed at 0.15mm.

Wow peter, that is exactly what I've been looking for.
What kind of design rules have you been following when designing for multi material? I've read that FLEX and PLA doesn't like to stick to each other, this needs to be accounted for during design.
For me this is one of the very unique things that can't be done any other way. I would love to add living hinges to my designs, or add soft grips.

TPU and PLA will fuse, but not as well as PLA-PLA or TPU-TPU. So an interface between TPU and PLA will be a weak point in the design.
The solution is to design it so the two materials interlock, like puzzle pieces.
Re: Look at my awesome MMU prints!
This is a "stained glass" flower made using four colors of transparent ABS plus brown.
Printed at 0.25mm, this is an easy print with the MMU because it minimizes the number of material changes.
I printed it using Hatchbox Transparent ABS, a product that doesn't seem to be for sale anymore and I don't recommend. It's incredibly brittle and all the loading/unloading with the MMU was causing it to break constantly. But I've got a pile of the stuff so I may be making more "stained glass" things. Transparent PETG or PLA should work just as well.
I can also see using different infill settings and patterns to create different textures, similar to the textures you can get with real stained glass.

First successful print! Fresh rolls of Inland PLA. Not a single jam on load/unload. One skipped white layer very early in the belly, but long unattended print. 205C/200C temp, Generic PLA load/unload/RAM settings, my post-processor to drop temp to 195C during RAM. Stock purge isn't enough, I need to shorten it white->black and extend it black->white to avoid a bit of gray in the upper wool.

Looking good Paul. I really like the multicolor sheep for some reason.

That sheep looks freaking great! So need to buy some more black and white, seams to always runout that fastest.
Re: Look at my awesome MMU prints!
Awesome sheep!
Which Inlands have you used? I find the settings vary color to color and roll to roll with them. If I could find a material I could just buy colors blindly and hit print it'd be worth a premium. As I understand it, that's unrealistic. 🙂

I used the black and white version at this Amazon link. Inland 1.75mm Black PLA 3D Printer Filament - 1kg Spool (2.2 lbs)
I've since ordered most of the other colors on the page, as well as two colors of PLA+ (since it comes in red). I'll try them out and report back.
