Faux Wood Grain using MMU! - eviltoast

I made a magsafe mount in black for my Kia and I didn’t like the layer lines on the curved parts, but it gave me the idea to try using wood

I have a 3D Chameleon MMU so I added color changes randomly throughout between two shades of brown. One is wood, one is PLA.

It honestly came out way better than I even expected!

If anyone wants the STL I can provide it!

    Do you think printing without purge would make it look better? Or would it just blend into an medium brown

      I think better, if there was always a little bit of leftover filament the pattern will be more random I think. With more gradual gradients

    Ah, I was trying to understand what MMU was. Then I realized off of those ridges that this was a 3D printed model. I was looking at the “marbling” and imaging it was some sort of putty or something akin to sculpey. It looks both groovy and comfy and you did a great job =)

        Yeah, you guys always amaze me. On account of being able to model things spatially in CAD-esq software. It’s a skill I never picked up on, and one that I really enjoy seeing in practice =)

            Super cool, I’m gunna show the missus. She loves stuff like this. We’re renting, but I hope someday I can set her up with a whole workshop and she can tinker away all day and night. Because it’s what she loves most (as seen above). Any cool resources you’d like to point us towards? I’ll pass them on and maybe we can figure out some kinda “micro” studio we could implement in our current situation. I miss being in a major city, because I miss creation-spaces. While I am absolutely awful at this stuff (as previously stated) I am really good with pen and paper stuff. Stuff I can get my hands on. And loved hanging with with folks like you while just doodling away in spaces like that =)

                Shut the front door! My wifey just popped in and I showed her your work and she got green with envy and for sure is starting to have a think about how to create some kind of modular setup. Any recommendations for something small form then if you’re working out of a closet? (I am also laughing because I once was a closet -> computer person and you do what you gotta do in life =P!)

                Gunna pass those guys on and thanks a slew for everything even if we leave it at this =)!

                  You mean for storing the printers and stuff? Most use IKEA side tables or those metal racks if they have many. I use assorted short tables, very makeshift.

                  It’s an absolute disaster zone right now because I have so many concurrent projects 😂

                  Honestly don’t know, I looked at your profile and it has an option for adding you as a favorite so I did that. I don’t know what it means though lol

                  I completely ditched Reddit so I’ll be on here a bunch I have so many projects I want to share

    I’d love a 3D chameleon for my printer, but their shipping rate (I live in EU) is absolutely insane and unreasonable since they don’t even handle import and taxes for that price.

    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.

    Be careful with PLA in your car, it will probably deform in the sun.

      For sure! Luckily I park in an underground garage, so my car interior never really gets over 90

      I have some PC just in case it does warp
