With Sunlu’s new filament joiner coming out, I might give this a try by splicing segments of different browns together into a big roll. It’s a very near concept, and your print looks amazing!
Gist time I sliced something for my AMS lite I was flabbergasted by the increase in printing time and waste.
For those unaware, since you’re often having 4 filament changes per layer, each of which take about a minute, a 1hr mono-fillament print can suddenly turn into a 36-hr print with 5-10x more filament being purged than ends up in the model.
It’s really cool, but super wasteful.
But you can strategize to minimize filament changes by splitting up a model and stacking it to minimize filament changes per layer. This one only took about 8 hours.
One reason I love the 3D chameleon is that it is easily modified in how it operates.
I have mine doing color changes at 20 seconds! It shaves many hours off of some big 4 color prints
I always Purge to infill and if there is a lot of purge material in the block I will add an object that is printed using the Purge. Something that I don’t mind being stripey
What annoys me and I don’t entirely understand is the purge tower. If I purge to infill or another object, why am I still having to build this dumb tower? If you choose to disable the tower, it disables the purge to infill option.
If the infill is enough to take up the entire purge volume needed to get rid of the previous color, then you are right.
Most of the time there are sections where there is not enough infill to purge what it needs to though
Since it’s not a good idea to extrude filament into open space, it has to build up a structure for that later Purge. That’s why it seems to make a hollow pointless Purge Tower sometimes.
Another factor is the minimum Purge amount. I think that is set in the filament settings. By default it is not zero, meaning it will always create the tower no matter what, though it might be really skinny.
If you add objects that will be created from The Purge material you should see that Purge Tower get smaller when you reslice, or at least less dense
Absolutely, I was going to use a lighter shade of wood it kept clogging on me. Do I switched to the light brown pla. I think moisture is a big component in that too
You might try a 0.6mm nozzle, I know some manufacturers recommend >0.4 for filaments with filling in them.Very cool project though, you’re giving me some ideas.
I feel it. Those quick-swap nozzles are pretty appealing. Every time I swap a nozzle on the bambu I literally swap the entire hotend and unplug 3 delicate connectors. I’m worried they’ll break after a couple dozen swaps.

How much purge for something like this?
I’ll check the slicer again but it was really small. Most of the purge went into infill instead. Maybe like 5 grams?
I had my purge values low to encourage blending of the colors. I might try using 0 for purge volumes next time to encourage more natural blending.
purge tower was pretty hollow

That’s a great idea! Would be such a faster print too

Sanded and assembled!
That’s brilliant. What nozzle diameter and layer height did you use?
Thank you! Standard 0.4mm nozzle, 0.2mm layers
One of those two filaments is wood fill right? Do you ever get clogs with the 0.4 nozzle?
Absolutely, I was going to use a lighter shade of wood it kept clogging on me. Do I switched to the light brown pla. I think moisture is a big component in that too

Yeah I might try that next time. I have .8 and 1.0 too, but too lazy to keep swapping 😂
I feel it. Those quick-swap nozzles are pretty appealing. Every time I swap a nozzle on the bambu I literally swap the entire hotend and unplug 3 delicate connectors. I’m worried they’ll break after a couple dozen swaps.
I couldnt do it! I bought a pack of volcano nozzles for dirt cheap in all sizes, volcano is forever!
That’s beautiful and extremely creative. I should fix my printer.
Do it!! And thank you!
