This looks awesome! Exciting to see what happens in this space.

I can imagine filament vendors making bundles of filaments with interesting mixes of colors. CMYKW is an obvious one, but there must be other color combinations that will mix in interesting ways.

There's a growing community around the OrcaSlicer - Full Spectrum fork that started all of this, which is attributed in the article. It's a cool technique and I expect all of the mainstream slicers will have it soon. You could already do this technique with OrcaSlicer with Prusa printers or cheaper options like the Snapmaker U1

The "Prusa ColorMix Cones" model is not what I'd recommend. I don't know why they made it like that for 3 and 4 colors other than to do something different than what the community was already doing. For 4 colors the PeggyPallette mini they used as inspiration is a much better model: https://makerworld.com/en/models/2519356-peggypalette-mini-3... You specifically want the dome shape to visualize how the layers blend at different angles. The fixed angle of the cones in the Prusa model misses the point and I don't know why they did that other than to be different.

The article goes on at length about their filament mixing model which sounds cool until you see the part that they only tested with Prusament PLA. Again, I think the open source community was already doing a good job with this.

There are several filament databases other than the one they're linking to that have TD values, which sprang out of the HueForge community. There are cheap tools from small makers to measure TD and color, too. One database: https://3dfilamentprofiles.com/

I'm glad they gave attribution to some of the sources of all of these ideas, but to be completely honest it's getting a little tiring to see everything the open source communities do get wrapped up, prefixed with a Prusa- brand prefix, and resold to us. Make sure you look beyond the Prusa official everything to get a sense of what the community is doing with all of this. I know I'm going to get downvoted for saying anything that isn't 100% pro-Prusa, but this is one topic where the open source community is quite a bit ahead and it's worth looking at what's out there.

This is exactly what I was hoping for to knock Bambu down a few notches.... Definitely makes Prusa an even better contender in the space.

This was already available in an OrcaSlicer fork (the one they used as an inspiration) which works with Bambu and Prusa printers.

They're just putting the technique into their branded slicer which should make it easier to access for people who don't like using OrcaSlicer.

From what I've seen in the blog post, this is underselling it a bit. They did improve on the color mixing model, and they're launching filaments to match to make it an end-to-end product.

No this isn't rocket science, and there's definitely a vibrant FOSS community actually pioneering this and that is probably the best place to be on the true frontier, but there is productization effort here. Considering people always advocate for Bambu for "making it easy to buy", Prusa also deserves credit when they try. They certainly get knocked when they don't.

As someone deeply embedded into the FOSS community myself, it's sometimes really annoying when we sabotage the better players. It only helps the worse ones.

The big thing for me is this plus the INDX from Bondtech. And at least for now they are the exclusive partner for that (you can still buy on your own and add to any machine).

INDX already has fast color changes and produces far FAR less waste than an AMS. And that’s what sold me.

Then the coloring mixing stuff started coming from the community. Now you don’t need to buy 30 colors of filament for many uses. Thats a serious upside. And it really benefits from multiple toolheads.

It’s a great confluence of events if you’re in the Prusa ecosystem or just don’t want a Bambu or U1.

Well said. They’re also sharing everything!

PrusaSlicer is used as a base by some others, they’ll get this.

Version 3 is coming soon, they’ve promised good things. I’m curious what shows up.

They also open sourced their color mixing model so if people think it’s better they can switch. And they’re using and adding their stuff to the open print tag database they’ve already cooperated with others on.

This seems like all upside to the community to me.
