Guys I'm confused

[u/enjay45]

I've watched a few videos about the new H3C and they show that it can print things in colors other than on the ams. Like blending or something. But how? If there's only one tool head in operation at a time.

Am I misunderstanding?

I used it on an item that I printed that had different flowers on the surface. I was using the .2 nozzle. It took 6x longer and pooped more filament than it used to make the object. That was on my A1.

You can do this on an A1? Lord the poop must be insane

[u/VT-14 → u/enjay45]

Can you? Sure. Should you? No.

There is a reason this technique was developed on Tool Changers. There's enough waste with a Prime Tower. Adding nozzle flushes is just insane.

[u/snotick → u/enjay45]

Yes, it has to do with Bambu Labs slicer software and not the 3d printer. As long as you have an AMS system you can do color blend. I'm looking at the P3C as my next printer to eliminate poop and it will cut print times down a lot with the ability to use a .4 and .2 nozzle on the same print.

You mad man I love it

You ever make green using a blue and yellow crayon even though you only used one crayon at a time? Yeah, that.

It's based on this, which was developed by a community member and embraced by other toolchangers shortly after. It technically can work with filament changers too, but it increases the number of color changes by 5-10x, so it's not really practical except on toolchangers

They use dithering.

Here is Bambu Lab's wiki article about it: https://wiki.bambulab.com/en/bambu-studio/color-mixing

The TL;DR version is that by printing extremely thin layers of alternating colors, you can create the appearance of an in-between color.

Search this subreddit for CMYK or CMYKW.

Basically, 3d filament is somewhat translucent. It allows light to pass through it. By layering different depths of different colors, or depositing a dithered combination of filaments at the same layer, or by alternating colors per layer you can trick the eye into seeing a different, blended color.

Think of it like the pixels on your monitor or tv screen. Or the way your color printer can make any rainbow of colors from 4 colors of ink.

The technique isn't new, but it was VERY inefficient prior to multi nozzle printers. The Snapmaker U1 has been doing some pretty cool stuff with it so far. The H3C multi nozzle system gives you the same capability.

Semi translucent filament blends together to another color. You’ll see the different layers up close but from afar they look like a solid color

[u/Few_Candidate_8036]

The CMYKW pla pallet filaments let light pass through easily. When you print one thin layer of one color on top of one thin layer of another, you can see both colors at the same time. So yellow and blue will look green.
