2 Colors in 1 - Unique Co-Extrusion Filament!

Dual-Color Filament: Gimmick or revolution? Redline Filament (GERMANY): tidd.ly/3nZafag 3DJake (EUROPE): geni.us/My3w8NW Matterhackers (USA): www.matterhackers.com/store/l/matterhackers-quantum-pla/sk/M4VVM2GS?aff=7479

[@jayphone1]

If I use your affiliate link for 3DJake and switch to 1000g does it still workout for you?

[@jayphone1]

I'd say gimmick but kind of revolutionary if the software could define the extrusion direction in a way that you could get specific colours to the outside. And revolutionary with functional materials.

[@CNCKitchen]

Yes, the affiliate links should work store-wide!

[@Luziferne]

With colors only its gimmicky, even if it looks VERY nice(I love Deep Space and Blue/Green). But Like you said, coaxial extrusions of one or even more different plastics could lead to filament were the strength of one part covers for the weakness of the other(s)

[@lokiwartooth1138]

Where can I get the model of you?

[@holz_ps]

It woud be interesting to see how the BondTech CHT nozzle would interfere with the color pattern after extrusion.

[@CNCKitchen]

I'll try that tomorrow, but I suppose it adds a bit of turbulence and messes with the result.

[@GynocentricEudomonic]

Bet it would result in a unique appearance every print, even with the same spool and model.

[@3DPrintingEagle]

That's what i was wondering as well, I'm exited for the result

[@chemistclips]

Y'all should go check out deckingman's mixing hotend!

[@brianzhang1088]

Can this filament show how turbulence the copper wire high flow hotend really is？

[@outofdarts]

Awesome video! One if my favorite blasters printed for me in 2020 had a tri-color filament that worked in much the same way. I do like the idea of reinforcing parts by coextrusion. We'll have to try that ourselves once it becomes available.

[@brandonallen2372]

That could have been filament made by FIlablend. They shut down operations in July of this year. Supposedly someone bought them out in August but there hasn't been much news since then.

[@Bobololo]

Some of the Lynxes that Silverfox has made were done with Filablend in a tri-blend. Really love the stuff and how it prints differently on direct drive and bowden

[@pnt1035]

As others mentioned, probably Filablend. I've still got some, and although some combinations work better than others, some work really well for certain prints. It's regular PLA rather than silk.

[@Killercop3000]

I also want to try out some triblend for my own talonclaw. Can't wait to hear more news about the filablend situation.

[@ZURAD]

Calling it now, you're going to see an explosion of dual color filaments. This stuff is mesmerizing.

[@ge2719]

how long till we get ones that look like tooth paste though? :P white with 4 small red stripes might be interesting, edit. actually, thatd probably be called candy cane colour :P

[@Cakemagic1]

I won't say which exact company I work for, but yea even our company got the dual filament at similar time as 3DJake and many others. It's very easy to make and a lot of brands are just simply the exact same thing, since they come from same manufacturer.

[@vegancatmomNL]

Seeing those dual colour filaments and silk filament is the reason I started 3d printing :)

[@webx135]

Nailed the prediction.

[@ChiseledDiamond]

"Co extrusion is something you're familiar with" (shows toilet) Oh god.

[@pyro3125]

Hi Stefan, my company uses extrusion and coextrusion for various products we produce (we have 50 extrusion line running 24/7) Just so you know, the first graphic you’ve shown is wrong, for coextrusion, you add the second material a bit later inside the tooling, otherwise you will have an inconsistant mixing between the two materials (you add one material on top of the other basically) I would be curious how far filament makers can go, we currently run one production line doing a tetra extrusion, with clear pvc, soft pvc, white pvc and a WPC, so why not a 4 color filament ?

[@CNCKitchen]

Thanks for letting us know!

[@Spectron2077]

@Pyro31 how would you coextrude a core inside of a coextrusion machine

[@pyro3125]

@@Spectron2077 you don’t, you first extrude the core, then add the skin layer on top Ex: if you want a fibre reinforced core, you extrude just the core, than inside the tool the skin material is added on top of the core, usually in the last 1/3 part of the tool Edit : but everything is done inside the tool, I wish I could send you some pictures or videos I have

[@IanSlothieRolfe]

i like the "deep space" one best, it shows of the 2-colour nature the best (at least to my eyes). This is a fascinating idea.

[@d3c0deFPV]

Deep space looks amazing. I'm going to pick some up if i can.

[@DaniMakes]

The extruding one type inside another could lead to a clear outer layer that is thin and an inner layer of an abrasive plastic like glow or similar. This could make those types of filaments extrude longer without damaging the hotend! Imagine all the abrasive filaments being used on standard brass hotends without any worry!

[@jawms]

This is a lovely idea! The earlier abs/pc video shows that it would work too!

[@CNCKitchen]

Great idea!

[@licensetodrive9930]

A transparent + glow-in-the-dark version could produce quite interesting results. I have both, so might as well try printing them with that multi-colour filament you can print yourself.

[@jorgeestefania3184]

OMG can you update the comment if U do it please?

[@licensetodrive9930]

​@@jorgeestefania3184 My printer currently has 3 hours left on its current print, after that I'll start printing transparent+clear stuff, first printing the filament, then a small object with that filament, then the same object in just glow-in-the-dark to compare the two. I shall update the parent comment with how to find photo(s) of my testing in many hours time, I can't post a direct link so will add photo links in the comments of the "3D-Printable Filament! -Print Your Own Filament for Multi-Color!" thing, under my username there Haku3D.

[@Bakamoichigei]

eSUN recently came out with an interesting glow in the dark filament... It's a sort of resin-looking translucent black, but it's full of glow in the dark pigment and tiny silver sparkles... Neither of which you can see unless the material is glowing...and then the sparkles really catch and reflect the glow. I need to get a spool, it looks spectacular. :D (They also have a white filament that glows in the dark in rainbow colors.)

[@Kalvinjj]

@@licensetodrive9930 To be honest this got me curious so let's leave a comment as a marker too.

Raspberry and aluminum is my personal favorite

[@olafb.2929]

It actually looks nice and you got me interested now. The idea of co-extrusion of different materials to improve certain properties is simple, and great!

[@aidanpetrie5141]

Absolutely loving the weekly uploads! I know its probably a lot of work but the effort of it all is not lost on us, Stefan!

[@CNCKitchen]

I'll probably remain every two weeks. This was kind of an exception and the effort would otherwise kill me.

[@tbr1980]

I’ve been printing with 3DJakes new magicPLA the past week or so, Frozen Lavender/Sunset Sky and Deep Space. They are all gorgeous, I think Deep Space is my favourite.

[@CNCKitchen]

Good taste 👌

[@loughkb]

Thanks for mentioning the weaker layer adhesion. That was the first question I had. Most of my prints are functional and need strength. I'd bought a reel of geeetek silk silver and loved the way it looks, but found it to be useless for 90% of my prints due to it's poor layer adheasion.

[@johndaniels1197]

One of the long-term downsides to co-extrusion of two different kinds of plastic (not just two colors of the same kind of plastic), is that it'll make recycling more difficult. If you know, for example, that all your waste is ABS you could recycle that into new ABS filament of a mixed color. If your waste scraps are a mixture of PETG and Nylon, recycling becomes a whole new challenge because of the different properties of each. This also goes for any prints. Recycling plastic was already a bit of a difficult proposition, but now we're talking about manufacturing new products made of mixed plastics which may not be recyclable at all. I guess we just grind it up and put it in the landfill with a hundred billion tons of other mixed plastic to sit forever. Something to think about.

[@captainheat2314]

3D printed stuff is nowhere near as disposable made as one-time use plastic packaging

[@satibel]

You could just melt and mix and have cheap filament. Though for stuf like abs/pc you can simply use acetone to dissolve the abs

[@renegibbetnich7883]

We'd need to stick to polymers of the same type. I'd imagine we use it to either create fancy new optical effects like seen or enhance the printability of for example moisture sensitive filaments by encasing the sensible core in an modified shell. I am thinking of CPE/PCTG inside of PETG.

[@janfiala1346]

You can use a mixture of crushed plastics as a component in road construction.

[@iq911506]

I remember seeing 3 color coextruded filament at CES in 2015. It was fascinating to see and I'm glad to see it becoming more commercialized now

[@Malaphor2501]

Awesome filaments. I really like the way Frozen gold, green and white, and alu-raspberry look like they frost over and then thaw out as you spin it, but I really like the color change from Deep Space and pink and yellow.

[@tad2021]

Been using mixing extruders for this effect for serval years. Big diff to mixed filament is the orientation is constant. Commerical, Filablend has/was/will be making three color filament. Found them a couple years ago. They shutdown last year, but it seems they will be coming back soon.

[@thingswelike]

Fabulous lighting and photography/videography Stefan!

[@CNCKitchen]

Thanks, always happy to heat that.

[@Storebrand_]

Would love to see a silky silver with a flat grey. Could achieve a really nice metal look.

[@mocotonio]

PrintaLot has been making filament like that for some good years already.

[@goodtobegeek]

Another great video, and I really appreciate how you've done so much more than just a 'look at this sparkly filament' video. Also, great that you showed us what the filament is from other outlets, not just your supplier. It's this level of depth and honesty thay I strive for when making videos for my employer's channel. Thanks Stefan!

[@eulachonfish]

I agree with you exactly, deep space and sunset sky are absolutely stunning. I'm a functional parts guy for the most part but I could definitely make something pretty with these.

[@dmanero]

defiantly going to get my hands on this filament, love the blue/green and deep space.

[@markmorgan8378]

Sunset Sky for sure. Some pretty cool filament.

[@wesleyvanzwol4916]

love them. I had put them between the colors my clients can choose from for printing there led names and imminently had an order to print in deep space.

[@CooperDuper3000]

This guy never stops amaze me with his content. Nice, as always. Pink and yellow and sunset sky are my favourites so far.

[@CNCKitchen]

Thanks, happy to hear that!

[@patprop74]

I am not one that cares much about filament colors, I buy only two, White and Grey, and have been buying only those two colors for years, However, these two-tone two-strands actually make me want to try it!

[@thai9503]

Aluminium raspberry 😍😍😍 I would love a roll off that

[@incinerati]

You can achieve a similar effect with a sharpie, by fixing it to paint one side of the filament. It worked for me without any issues with PLA. I'm not sure if it would work with other materials as well.

[@vegancatmomNL]

that is a smart idea! going to try that soon :)

[@edwinirizarry9277]

I have to say there are so many great colors but the deep space is so eye catching to me

[@GoBayside]

Could you slice to bias 'East To West' to get color A, then parts 'West to East' to get color B? For that matter, could you do more than 2 colors?

[@woodwaker1]

Could you imagine this process with changing the filament colors in the extruding process, a veritable rainbow of color changes

[@MelSavageKiller]

I love these new filaments, been using the 3DJake ones for about a week and already ordered more.

[@nikiichan]

Green Blue and Deep Space are so pretty :o I never wanted anything decorative that was 3d printed but these filaments have made me reconsider that.

[@Fitzling]

Wow this new Filament is AWSOME

[@UltraNoobian]

First thing that comes to mind, I don't think this will work with your diy high flow nozzle or the bondtech nozzle.

[@alexanderthomas2660]

This is great, it's a rather simple idea but with a striking result. I like the Sunset Sky. Also nice that you confirmed my hunch that silk filaments need higher temperatures and even then the results aren't very strong.

[@MatrixRay19]

The contrast in "Filled sausages? Co-Extrusion!" is a truly a work of art. Hahahahahah

[@Cermagine]

I really love this, silk PLAs are impressive but these do bring a whole other dimension and lustre to prints. I need to get my hands on my hands on Deep Space, Sunsent Sky and Pink and Yellow!

[@dijkstw2]

Funny! Just started printed the 3dJake Version of the one tonight! 230/60 perfect flow and a beautifull result!

[@superbrain3848]

i have already a Blue&Green spool of it here, sadly my Printer is out of commission because of some damage on the motion system. Cant wait to print something with it.

[@lennartbruggink1590]

Very nice video! I love the gold and purple personally.

[@ge2719]

6:30 i was wondering that. i got a gold silk filament for christmas last year, and it was easy to just pull the layers apart, could literally unwind the print. managed to make it better calibrating the temp but still, was always noticeably weaker. maybe a good case for testing salt annealing to make it stronger, and be interesting to see what it does to the surface finish.

[@Bakamoichigei]

Those are some gorgeous filaments!

[@daltonmckee4788]

This filament is cool. Almost looks like you are shining colored light on the parts for the B roll

[@woodwaker1]

Really interesting - would be exciting to see filaments that had different materials that could work together to provide new strengths or other properties

[@satibel]

The carbon wire core ones are very interesting imo Though conductive filament+copper core may be really interesting too.

[@DamnCyrus]

I've been eyeing some filament that looked like the Sun Sky for awhile now, it just looks like it'd be beautiful in a Print with Fire

[@cyblue79]

love the idea. blue and green is good.

[@ChrisAbbey]

That deep space is beautiful... though pink and yellow is a strong contender! Really I just hope they get to the dual material core filament, I can see that being super useful for a range of industrial uses.

[@henricoderre]

I love this type of filament! It's COOL.

[@BulletsNBrass]

Visually they're fun, but I think you hit on the long term importance with your ABS/PC combo. Being able to blend the properties of two materials in a controlled manner opens up huge possibilities. Beyond the one you did, something where you take a strong but less flexible material and combine it with TPU as an outer shell and you probably get a supremely impact resistant material. The TPU distributes the impact across a larger area while the less flexible material then FURTHER distributes it while resisting distortion of the overall part. I'm not a materials scientist but even I can see some massive advantages in various combinations.

[@innocentidiot9521]

I love frozen gold. Your videos are always nice and informative👍

[@ukaszkarpik3476]

Deep space looks awesome!

[@matneu27]

I bought a spool from 3djake and could agree that the optical effects are quite nice. It's a interesting fact that you talked about the case of mechanical stability. As you had shown, the silk only filaments, in my case the extrudr "bio vision" is a crap for mechanical parts that have to hold something. They are only usable for items to place on a shelf with a big "do not touch" sign.

[@mkesenheimer]

Talking about dual extrusion and showing your toilet - love this kind of humor :D

[@rrlives]

The toilet joke was the best! 🤣

[@BRUXXUS]

Oooh! I’ve been really wanting some iridescent filament. This is getting close.

[@tride.design]

I'd like to see such dual-color transparent fillament. Such dual-color filaments are awesome if material is the same , although I wouldn't use silky ones because of their mechanical properties and I wouldn't mix different plastic materials because it makes them impossible to recycle properly and efficiently.

I'm really excited fo composite polymer coextruded filaments.

[@berkakarcaloglu1915]

Don't know about color choice but I feel like if they co extruded PEEK and PEKK together, it could be awesome. Or would help with anealing, provide killer chemical resistance and overall be a great functional material. Or would also cost alot but would be really cool :P

[@captainheat2314]

PPS outside and ULTEM core would also be amazing

[@Cyberdactyl]

The toilet shot and 'extrusion' was hilarious. :)

[@KryaDiere]

I'm a sucker for those "chameleon" coloured paints, so I really hope this catches on with other companies (I'm in asia so importing these from the west will kill my wallet). The fact it opens the door up to functional material is an added plus.

[@AmaroqStarwind]

Some experiments I would love to see: 1 - What if you rotated or shifted the infill between layers? [Would this affect strength?] 2 - What if you distorted the infill pattern to better match the contours of the part? [Would this have a positive impact on strength, or would it just look weird?] 3 - What if you used perlin noise to create a somewhat random infill pattern? [Chaos and entropy!] 4 - What if you had a spinning nozzle that twisted filament as it's extruded?

[@RobertSzasz]

So I think an optimum hot end is going to have a static mixer of some sort to give better heat transfer. But this filament highlights some uses of the near laminar flow in conventional nozzles. I wonder if nozzle design could be optimized for laminar flow.

[@Kalvinjj]

it is laminar on any normal nozzle tho, at the viscosity and speed of the filament flow there's basically no way to get a turbulent flow as per fluid dynamics. If you mean a nice and smooth extruded filament at the output, then I get it tho, from what I've seen of Stephan's tests here, a worn nozzle or excessive extrusion speed will screw that up.

[@bigflytrap]

Gorgeous filament!

[@Gambinaceo]

You can create your own home made dual color filament, just need to create a 3d 1.75mm thickness spiral in your favourite 3d editor and print half height with one color and the other half with another color and using a 0.1mm nozzle, then use that printed spiral as filament. It's not perfect but works really well.

[@Mrcaffinebean]

That’s really interesting! I am also mostly a functional printer but sometimes I do something for the kids in a pretty color.

I can't decide which color combo I like best, but agreed, some potential for multi-material is really interesting

[@gavinboulton6878]

I bought three spools of this from 3D-Jake. Really cool stuff. Can give variable results - ie some prints can be awesome and look amazing, Some however can be hit/miss where the change of colour can show up the layer lines really obviously. However I really like it, will make for some great prints. Easy to print (PLA profile) just bump temperature a few degrees ( a little like silk filaments). I recommend the blue/green (it looks awesome)!

[@Boogie3D]

I am wondering what would the results look like when a rolling-screw extruder woud be used (which rotates the filament).

On a A20m people have been experimenting with pla + pteg for example to get stronger layer bonding, I do think print direction does matter so software maybe a post processor would help.

This combo was my thought too-high hardness of PLA with high toughness of PETg. PC with carbon fiber infused PETg would have some very interesting possibilities.

I wonder how this would print with those non standard nozzles you used in a couple of recent videos.

[@rcmaniac25]

I now feel like I need to try this again. I remember watching SunShine's video but IIRC, the point was to make unique colors as opposed to co-extrusion/2-sided filament. Some time later I saw some posts on Twitter from some Japanese 3D printing people where they had 2 and even 3 side-colored prints (my fav was a red/green/blue vase). I tried this myself (I did a 3 color one using a Palette to produce the non-symmetric 3 color filament). The filament looked awesome. The extrusion looked awesome. The print... just kinda blended. Maybe it was the 0.4mm nozzle, maybe I didn't print fast enough, maybe I need to turn off retractions (though I did a vase). It just didn't work for me. The small-batch production just made it hard to justify the lack of effect. If mass production does it, awesome. But I'm not sure if there's a trick to getting it to work unless it only works with the more traditional filament instead of SunShine's method.

[@3DMusketeers]

This material is so cool! I have seen stuff like that before, but never used it! How does this look through that CHT nozzle that will split it up? Will have to give this material a try out!

[@swedneck]

I really love the effect the prints get on one side where there's a dominant color with the other color being visible on the fringe, i wonder if it'd be possible to make that effect appear on every side?
