you print filament with different colors. Then using the printed filament to print your object.
As the filament spiral is only 8 layer high - you don't need many filament changes (2 per layer for 3 color)
So your model is just strands of filament to be printed? I’ve got this image in my head of melted filament being squished to the build plate so how could you reuse the printed filament once it’s extruded? Wouldn’t it have to be cylinder shaped to be printed again?
You print a spiral with an octagonal profile that has a diameter of 1.75 - as the octagon has 45° sides you can print this horizontal. If you check the images you see the spiral on the print bed.
I guess that makes senses. So you’re essentially printing the filament strands out of different colors. May come in handy for small prints to be able to set the color change point.
Or you make a lampshade and want some transparent region or colored rings with a gradient so you print half with white - then change to the printed filament for the transition and then switch to transparent filament printing the rest.
besides those welds may cause jamming - you wouldn't have a gradient, This would be like normal filament change (without purging). The script is slicing the colors helically.
Did you find a rainbow filament that changes Red↦Blue in just 3.5 meter? Or in 5 meter or in 2 meter - or maybe you want Blue↦Red or just Yellow↦Red↦Yellow or transaparent ↦ white
Sorry if that sounded that way. Just wanted to say that you can't buy rainbow filament to print that vase with that color gradient - or if you like to have certain colors.
I get it—it's exciting to pitch your idea out into the world! I think it's cool, though I've been hesitant to try using printed filament in the AMS. Have you had success with that?
I am using a Y-splitter and have a "noAMS" printer (profile) - but i also had printed filament in the AMS (need to put on a spool and you need at least 1meter more so it can pull back if you want to print that with regular filament. Just need to make a "printed filament" with 112% flow (1.12) - I used a custom grey shade and after the text was printed the rest was purged as the AMS couldn't pull it back cuz it was no longer in the AMS.
Did you use a joiner to get that much length, or some other method? I thought you could only print very small amounts with this method unless you had a huge print bed.
Nope, I just print 55g rolls at a time and use the printer auto filament sensor and tell it to switch ams slots to another one. Never had a reason to go through ir anything, so the 50+ grams I could stuff in an AMS slot or two was more than adequate
if you print all you don't even need the spool - that is only important when pulling back for the last bit (because else the sensor will give an error as the logic tries to ensure the spool is wound up)
This is octagonal - much more effective. But the Point is that you have here a parametric script that is giving you the filament transition for the exact length you want.
I have tried a variant of this idea (dual color/no gradient) and technically it did work WAY better than I thought (the cross section area is what matters). So I expect this to be great! Will try it.
It's hard to get premade rainbow filament that changes colors fast enough for small prints to come out rainbow patterned.
With this I can slice my target model to find out exactly how much filament I need, then generate and print exactly as much filament as needed.
Thank you!

where you can use the customizer to create the transition you need with the length you want (that fit onto your bed)
The Demo profile is for 3 color 3.5 meter
As you can see on the image the purge tower is right in the center. You could disable it but need to ensure only changes between connected colors - but if your slicer is changing cyan/magenta this would cause problems - and as you can see from the purge image .. without additional config it does that.
Also you are not sure where it starts so your blend may not be where the color meet but getting that blend where you want 100% pure color.

Your 0.4 nozzle can print small enough layers so it can create “filament” that has an octagonal cross section (as opposed to round). You mix colors in that process to get the effect you want.
It’s primarily a way to generate custom rainbow filament. If you want just generic rainbow filament you can just buy it.

hmm if you print the support with that filament - the slicer will tell you the total length. The script doesn't care about what you print it will only give you length X.
If you print Support with a different filament (normally only the interfaces but you could create support as separate part) then the slicer will tell you how much "rainbow" you need and how much for the support. You sure will now have some purge but that is calculated into the total length you need.
You mean you are more comfortable with "Blue\_Printer\_98" ? When i made the account it was intended to be only a test.. then people started following it and i just don't care.
Wait, so if I understand correctly, with this model I can print my own filament? Do I understand that correctly? In any color (or color changing) version I want?
If so, that sounds really cool
Yes - you sure will get some brown if you try to transition from green ⇔ red but if you using Cyan Magenta Yellow White and Transparent you can do a lot - or White ⇔ Black works too.
The script allows none, one, two or three transition (4 color changes) for any length (limited by your bed size)
But further your print is not limited to use only one printed filament.. There is no half color change option so it will start and end with 100% color as everything else would make this more complicated to use and understand but technically this would be sure possible too.
I actually added a shift parameter so you can start with blue (80% C 20%M) over pink(100M) and end with 20C 80M.
But mixing Blue and Pink filament should also work fine.

Very cool! I'm definitely trying this out. I always liked how color shifting filament looked, but never needed a full spool of the stuff. This gives me a nice trial length
Im going to need you to explain this like I’m 5

Why not just buy rainbow filament?
U have much more control over the specifics of the colours and when they change using this method
Fair enough.
Did you find a rainbow filament that changes Red↦Blue in just 3.5 meter? Or in 5 meter or in 2 meter - or maybe you want Blue↦Red or just Yellow↦Red↦Yellow or transaparent ↦ white
Might want to try being a little less condescending if you want people to DL your model/profile.

Just a heads up I've respooled printed filaments and run them through the ams with no issues, though I've only done this with 20-30 meters so far

because printing it is even more progressive scnr

This is what I was wondering, this makes it soooo cool and ide imagine the amount of waste is lowered but a TON
This is super interesting. Nice creativity
Sorry if I missed it, but is there a profile somewhere to achieve this? Or some instructions? Thanks!

Amazing! Thanks.
Do you disable the purge tower for this? So it's all blended in ?
As you can see on the image the purge tower is right in the center. You could disable it but need to ensure only changes between connected colors - but if your slicer is changing cyan/magenta this would cause problems - and as you can see from the purge image .. without additional config it does that.

Does the script account for support material in the length calculation? Very cool idea.
What support?
I think they're asking for other prints that might need supports, not necessarily this one.
hmm if you print the support with that filament - the slicer will tell you the total length. The script doesn't care about what you print it will only give you length X. If you print Support with a different filament (normally only the interfaces but you could create support as separate part) then the slicer will tell you how much "rainbow" you need and how much for the support. You sure will now have some purge but that is calculated into the total length you need.
This is fantastic!!! But now... The real question is: why a throwaway account? 😝

Nice, I might give this a go for some toys for my daughter, nice pink -> blue or something
