Mixing the filaments together to mix color is a great example of good ideas on paper but bad in reality. Pellet extrusion mixes color pellets with uncolored pellets, that works great. Though it needs a screw and lots of pressure. But surely using filament would work too. But no, it doesn’t work. Worth a shot though.

Full Color 3D Printing exists, but it is not FDM. Mimaki, for example, sells a resin-based printer that can print with over 10 million colors. A thin layer of white resin is applied as a base and cured. The ink is then applied as with an inkjet printer. The results are amazing but it is a bit more expensive.

@VioFax 3 күн бұрын

I always had wondered why resin couldn't do it out of the box... Just use chemistry to make pigments in the resin harden a different color with different intensities or colors of light rays... But what do i know im not a chemist.

@andreas.grundler 3 күн бұрын

@@VioFax Theoretically, you could add pigments to a small amount of resin and print with it, but we are talking about tiny amounts of one color at a time. The ink that is applied to the model after the resin layer is also not mixed. Our brain does that. For example, if you look at a photo printed by an inkjet printer under a microscope, you would see tiny dots of color. Just as with an inkjet printer, tiny dots of cyan, magenta, yellow and black are simply applied in the appropriate proportions and we only have the impression of seeing these colors. Theoretically, there is another way to create colors without pigments. Some butterfly wings shimmer in intense colors, but in reality these colors do not exist. Microscopic structures reflect and bend the light in a way that filters out certain colors, leaving only blue, for example.

i forget which big 3d printer youtuber it was but he made a video where he 3d printed his logo into a long serpentine string so the cross section was his logo. he then took that and ran it thru a filament maker to get it to the right shape which puts it thru a hot end.. to get it to 1.75mm and it didn't not mix. then he printed with it and cut a cross section of his printed part and his logo was still there squished down and not mixed... so when you said it wasn't mixing in the nozzle, i wasn't surprised at all.

I guess, the idea is was not to make a full color model, but to avoid buying a lot of filaments of different color. And it would be limited to tones that always keep all filaments flowing. We will have to wait for next idea to achieve this. I had that idea before 2019, but didn't have resources to make it real.

Really interesting video. I wasn't aware of this printer but I did buy a Geeetech A20M ages ago. That was a 2 in 1 out mixing hot end. Oh boy was that "fun" to get working well-ish. I swapped out the stock extruders for Ender 3 type single gear ones, the hot end assembly had back-flow discs intended to stop the filament pushing back up the heat break, great idea but they just clogged all the time, so I removed those and just made sure I kept filament loaded in both sides. Had to create a custom slicer profile for it based on one I'd found of Thingiverse, then found the purge blocks were so incredibly wasteful so I followed others in designing a purge bucket, then of course it needed custom firmware to work all that. In the end I did wind up with a printer that would print well in one or other loaded colour, it did gradients and mixing ok, and eventually I tuned the colour swaps so it purged into the purge bucket. I just wasn't using it enough to justify the space it was taking up though, so I passed it onto a family member and got another Ender 3 Pro :) It's still running fine and every so often I get a notification that someone has downloaded my profile, firmware etc from Thingiverse so I assume people are still trying with these printers :)

This was mentioned, but if a filament ran out, it would result in nastiness happening, as the filament would then push out via the back hole, and create a mess, perhaps a blob of death engulfing the hotend. V6 used to have a "brass diamond" nozzle, which had three heatbreaks, around 2017. This never took off because of the same reasons mentioned in this video. Now, is this a good technology? You really need black. There is a reason why color photos use "CMYK", and with 3D printing, you definitely need white, so you now have a nozzle that has to handle five filaments at once, as well as push all of them in. That, or use something fancy like water cooling to mitigate heat creep. I think this is a dead technology. Other 3D printing technologies like HP's that use multiple "jets" can already do this, so there isn't any reason a high end company would go back to this. Maybe we might see something where a filament line is automatically melted and extruded to pre-mix the filament before it goes into the hot-end, but nobody has done that yet, and that is a lot more complex than a current Palette model. This video does justice to this technology. It is an interesting branch, and had a lot of promise, but would take a lot of engineering to make it work well.

I picked up one of those color mixers, and swapped out the hotend for a dual nozzle, as I figured out it was doing all the things spoken of. Over the course of time mulling it over before the switch though, I had figured out a way to fix the color island issue within code, I just never got around to implementing it.... If you change the color gradient by an amount of extruder steps previous to the needed change and vise versa back then the correct mix should be available at the nozzle for the print at that moment when desired. The issue with the mixing I figured was due to a simple problem of not having a chamber to mix at all, they were just plain cuts to meet at the center. Heat creep could potentially be solved with better all metal hot ends with proper cooling. Too bad to hear it's on the back of the burner, but potentially I'll get down to writing something or someone will before me. I would also have to implement that mixer chamber because nothing was more disappointing than that.

Oh come on dude. Let's stop with the pearl clutching and think with our heads. There are millions of these in dumpsters. Everyone who wants the parts from an ender 3 like can easily get their hands on them and for this guy, his time is probably too valuable for doing anything other than just buying the parts he needs for a project to make sense. I reckon that's true with the majority of westerners. Baically it's a bit silly to complain that a single printer that was never going to be sued again by itself or for parts got a little crispy.

People printing articulated dragons to sell would love this printer tho. Now you don't need to buy co-extruded filament in limited colours, you can just stock up on any random PLA offcuts and feed the beast. Today's special, strawberry chocolate dragons. Consistent orientation too. In more practical terms, it seems like a really cool way to make PETG+TPU parts. The two bond together well but not well enough to just print one next to another, co-molded tool handle style, but if you do a few co-extruded layers inbetween you get a strong meshed connection between hard inner and soft outer shell. I played around with the concept with those printed spiral things, they do great at attaching layers of TPU to layers of PETG, but it's not too useful like that.
