20 Color 3D Printing! Co Print at Formnext 2023!

[@senurasenaratne5782]

my ender 3 started to print like that, it was a loose concentric nut. they probs forgot to bring the tools to the expo lol

[@cpace123]

Using that extra filament to make an object is brilliant, simply brilliant

[@johnmarro5352]

even the bambu printers can do this. they just didnt advertise it like co-print is. its a smart play for co-print honestly.

[@kaween1000]

That function is pure slicer-induced. It's been inside Prusaslicer for a very long time already, and they use Prusaslicer for the Chroma system. Hoping they'll support Orca too soon (they said they were looking into it) as I personally prefer Orca above Prusaslicer and Orca is fork of Bambustudio, which in its turn is a fork of Prusaslicer, which in its turn in a Slic3r fork. :

Joel is good at these, at distilling the painfully bad sales pitches into snappy bullet points.

[@DaveRobbiens]

[@ScottWinterringer]

This actually sounds like a good advancement for the community

[@ChrisHarmon1]

Hopefully, it's not some regular rc servo. I used to do small medical tube cutting, and we would change the high quality german manufactured cutting blades every 500 cuts. This required a nice square tube, but I can't imagine an xacto lasting much longer without cutting forces going up. The machines we used were pneumatic extend and retract.

on topic: the co print looks so cool! it's finally the multi-color printer adapter that everyone was hoping the A1 Mini (no flack just slight misadvertisement) was being advertised as. i'm super excited for this

[@VMTDesign]

Exactly!

[@GeekDetour]

I see layer shifts on the castle :)

[@FilamentFrenzy]

I was hyped about this, unfortunately after this video my hype was reduced to zero, the model on the print bed had many layer shifts, the quality was meh, the purge block was massive, cutting and purging to a block only is a bad idea unless your print bed is huge, why do you think the bambu poops ? Not to save material to save print space, a 20 colour print on an ender 3 sized bed would be comical, the organisation of the tubes and spools looks messy, the articulated print in the video shown as the purge block was not the purge block, it was a wipe to object and there was still a purge block on top of that too which needs to be clear, you can’t just wipe to an object and have no purge on top you still have a big purge block too, I feel like all the advancements they made with the chroma pad are overshadowed by everything else that is not as developed and as advanced as the chroma pad, just my 2 cents from the video, nothing but love for you joel ❤

[@gamejunkie7]

Hey Frenzy, I think this is a case of hardware guys not realizing they need to show pretty things vs assume everyone cares about "features". There is zero chance I would be showing off my brand new product on an ender when its compatible with newer corexy machines.
The purge block won't need to be any bigger than any other single extruder multi material system, since this is down to the slicer (mostly). The models they show are quite ugly, and lack any real details which in my opinion is a huge miss on their side.
The mass of PTFE tubes isn't really an issue for me when you think about what its doing. The retraction distance is quite a bit shorter, lending it to quicker color changes.
Last, they should have reached out to you and a few others that really push amazing prints out to show what this thing can do. I hope they send you a review unit.

[@1288832]

It doesn't work because Bowden. or very slowly.

[@rishirajbose2444]

Tbf the layer shifts are more likely the ender 3s motion systems fault, maybe incorrect input shaper values when they reassembled at the venue but I was surprised Joel didn't point it out. You're right about the cut and purge but if it's just a klipper script it can probably be configured to poop instead. I think it's still an interesting idea and I want to see them be able to actually go to market.

[@GamesJames]

Yea I agree. I was sketched out with the last of videos they posted on it and I didn’t back it. This seals it for me. That print is crap looking lol. Hope it ends up good but yea I’m out.

[@3dPrintingMillennial]

If you look closer to the base, it looks fine. He chose a poor model for demonstration because he's using a bed slinger with FAR too much weight. That's why it's shifted all over the place the higher it goes. Plus I've found that small cylindrical parts with color changes are very hard to make look nice (ie seam, coasting, etc). That astronaut model looked much better

[@ThePrintHouse]

Omer is the best elevator pitch representative at Formnext 2023. So knowledgeable about the product.

[@3DPrintingNerd]

Omer was a joy to chat with!

[@OreSetsero]

By the time your done with the cost of the printer, 4 extruders, the main hub and unit your cost is pretty up there. Why not just jump into a Bambu that has all this already? Just asking because I like the concept and is cool but just trying to see the benefit of "compatible" vs fully designed to work with an AMS.

[@TimothyStovall108]

Bought an Elegoo Neptune Plus a few weeks back, and really enjoy it. Saw this video shortly after, and recognized immediately how much of a game changer this thing is, but didn't really think about backing it at the time. Since then, I've have been, I guess somewhat, promoting myself to all these small business owners who are my clients, and seeing where I can design and create things for their businesses. Made me rethink the kickstarter, and realize how good of an investment it can potentially be. Certainly at the kickstarter price point. Got on and saw there was one more spot for the Hyper Early Bird KCM Set. Score. Nice B-Day present since the campaign also ends today on my birthday. Almost feels like the last spot was reserved for me. lol With the designs and creations spinning around in my head, this tool will certainly help bring those ideas to fruition easier. Switching between colors is cool, but it's the switching between different types of filament and operating range that sold me.

[@Chriss_Workshop]

I remember seeing an ad for this about a week ago. Pretty dope addition i'd love to upgade a machine with. Also, side note. Jesus that purge block

[@RockieOnly]

Yeah that block is huge, which is probably why bambu lab decided to yeet most of it off the build plate.

[@RealJoschi]

03:47 Well... nice layer shifts and underextrusions... must be the Ender, right? 🤐

[@chrisryan3445]

Yeah that looked pretty bad to me on the closeups, I would have thought that Klipper type firmware would have done away with all that but apparently not it seems.

[@MatiasSebastianAcevedo]

it's a new technology. wireless jam printing 🙃

[@KittenRaee]

They use custom extruders, custom config and custom printhead. I just hope this is some mild technical issue not addressed before/during the show and not representative of retail version

[@themacbookgamer]

Currently watching while printing on my Neptune 4 Pro. Now I kinda want the multi color upgrade...

[@norussian556]

[@RJRiemensnider]

I can't wait to find out more. I want this on my Voron with Revo Nozzles.

[@BelviGER]

So basically a palette like system but right above the hotend? So like a direct drive palette?
Or am I missing something?

[@PaganWizard]

I really like this a lot, and will be buying one or three in the very near future. I have to admit that I am concerned with how the cable seems to be dragging across the edge of the bed. Is there a way to mount this so it does not interfere with the print bed?? I have two printers that I want to use this on, one is an Ender 3 V3 SE, which does not have any 2020 or 2040, how can I attach this to that printer?? My other printer is an Ender 5 Plus, and I'm getting ready to buy a Tronxy 600x600x600 printer, is the cable that connects to the print head long enough to work with large 3D printers?? And lastly, can I upgrade from the BLTouch to a CRTouch??

[@prof.tahseen6104]

Wow. This is brilliant!

[@JFMeakerII]

I need this. I haven't been able to find anything to add multicolor capabilities to my Anycubic Mega X

[@DonsArtnGames]

LOVE the idea and concept, but I don't have the $500 to convert my printer to multicolor with this. If retail is going to be $1000 USD for the system PLUS the price of the printer to be converted PLUS the time to do the modifications, I would rather get another Bambu Lab with AMS.
Again, I LOVE the idea and I like the execution... I just think the price isn't worth it after the Kickstarter...

[@woodwaker1]

I got just the extruders and the control box for Klipper on the first day for $300 and plan on using it on one of my Rat Rigs. For that printer it is a bargain. My Prusa XL with 5 heads was over $4000 with shipping and taxes, so this seems like a good gamble.

[@gamerfun4619]

I love how you up load every day!!!!❤❤

[@anon_y_mousse]

I keep wondering if it would be possible to use clear filament and add colors in the nozzle to generate every color you need. The idea of printing an extra item as the "purge tower" is really good and makes me think someone should give it a try if no one has already, since nothing would be wasted then.

[@3dpprofessor]

Re: Mixing colors to clear: If you're talking about inserting color at the nozzle, you'll run into problems with the heat destroying the ink or still having to deal with smear and purging. However, the XYZ Printing Davinci Color actually one-upped this idea by using a neutral filament and adding pigment after laying down a layer with an inkjet head. However it ran into a problem because they mounted the 3d print nozzle and the inkjet head on the same carriage, so the inkjet head was in open air most of the time and if you didn't use every color on every layer then the ink would dry and clog the nozzle.
It proved the concept, but V2 would need an IDEX so the inkjet head was parked, and no one seems to be willing to do that right now. Plus, proprietary filament and proprietary inks... yeah.
However, when it worked the results were brilliant and allowed for discreet color changes to the point that you could put a photograph on a print. But the execution was flawed.

[@3dpprofessor]

Re: Purge objects: So the problem with purge objects is they need enough cross-sectional volume on every layer to allow for purging, and the average small print, especially with low infill, doesn't necessarily have that. And if the print changes cross-section volume as it goes up, say for instance it has a narrow neck for a while, then it might be okay in some areas but not others.
Add to that that multiple colors means multiple purges. Add to that that you can't just print a whole layer but you need to print part of the purge layer, stop, return to your main object to print, then switch colors, continue where you left off in your purge object until the purge is complete again, return to your main object to print the new color, repeat until the whole layer is complete, and then finish off the layer on your purge object. All in all it's a non-trivial problem that involves predicting where the purge will be in your print process and putting it into a print that was stopped part way through while finishing off another print completely. Not saying it can't be done, but it's rife with unsolved problems.

[@anon_y_mousse]

@@3dpprofessor Surely there are inks that aren't sensitive to heat, after all how does the color in current filament not get destroyed by being heated? But if not that, then why not four filaments for CMYK and mix in the nozzle?

[@anon_y_mousse]

@@3dpprofessor Would have to modify the slicer software for this, but it's not a problem if there's too little since the next color in use could finish off a given layer. Perhaps reducing the size of the heat chamber could force it to always have too little to purge.

[@3dpprofessor]

@@anon_y_mousse Ah, Color Mixing. Yes, there are those doing that as well. Nowadays you can buy a Zonestar 3D printer that you can mix CYMW filaments with 4 colors going into the nozzle, and a single mixed color coming out.
...well, kind of. First of all, the color isn't mixed as much as it's striped. Like those multi extrusion filaments. Or Aquafresh toothpaste. It gets smeared a little in the printing process, but it still favors one color or the other as you go around the finished print.
And then there's the problem that holes in a nozzles isn't directional. So let's say you want to print something that's pure cyan. So you halt movement on the Yellow, Magenta and White and only push on the Cyan into the nozzle where it gets all melty and comes out. But what's to stop it from coming out the Yellow, Magenta, or White feeds instead of the nozzle? So you have to make sure that those other colors are engaged, but now they're getting melty, so they're not pushing and we're back to the same problem. So you have to be constantly feeding all the colors all the time, even just a little bit. So getting a proper mix is impossible and at best all the colors come out muddy.
Also also, there's no one working on the software to resolve these issues. There was a decent slicer a while back that did some incredible work on it, even allowing you to import an image to define your colors, but the company making it stopped developing, removed those features from their official releases, it and it's hard to find these days.
Unfortunately, it seems that color mixing is a dead-end technology.

[@Haldirttraun]

Oow😮

[@awilliams1701]

I'm really interested in the mk4 MMU3 now. Prusa claims their newest method will actually reduce purge volume significantly from the MMU2 (or MMU3 on the mk3). Cutting the filament will increase it. So I'm interested in that. My last MMU2 print (period I'm waiting on the 3 before doing more) was the racinante model on printables. It took 2 months. It took 2.5 spools of silver. I probably threw at least half of that away. So the new prusa model sounds like I would be able to use less filament for the same result.

[@aeonjoey3d]

a bonafide upgrade. PLEASE show it on newer model coreXY machines like the K1

[@richdobbs6595]

This seems pretty expensive -- you are essentially buying an Ender 3 V2 as an accessory for the color management system. If you are going to have a single nozzle, it seems a waste to be investing in a lot of extruders, when you only need to be moving filament. It does save you the time for retraction through the bowden tube. I'm trying to develop a system where each additional filament added to the system costs less than an extruder.

[@boemioofworld]

I see creality are partnering with them. Any idea when this would come for ender series?

[@86volkan]

excellent tecnology, i will grab one of them

[@Ice99_22]

I backed them on Kickstarter. Going to give this a shot on and Ender 5 Plus I think. I’d like to run it on one of my K1 Max machines, but I think you’d lose too much build volume for my liking due to the size of the print head.

[@GeekGarageDK]

Pricewise i would rather buy a bambulabs X1 Carbon with AMS and their multi AMS system so you can add up to 4 AMS to one printer,16 slots for colors and materials. This way you get faster print and better selection. This thing is so expensive anyway so it seems a bit dumb to breath new life into old hardware this way.

[@bjrnsrensen8456]

Some people don't want to buy into a closed ecosystem like Bambu's. It's not just about price.

[@amil89]

why would we buy a locked down system that uses proprietary nozzles? What if Bambu goes bankrupt?
Same reason to never get smart lights that rely on a cloud. That company goes away, so do your lights.
I got a K1 Max instead. prints faster, way bigger, and was on sale for cheaper than the P1S.
I was able to set it up locally only and wasn't forced into signing up to send my data to china

[@xIsouLcruSHca]

[@MsJellyfan]

If you have a large printer like a Kobra Max that cost you $700+, this is a great add-on. But if you have a printer that cost you under $500, you might as well just get a new printer that comes with multi-color functionality. The Chromaprint system from Co Print is $430. You can get a Bambu A1 for $450 that comes ready to do multi-color prints.

[@BloodSteyn]

This looks great... but way too expensive for me. While in Kickstarter, the price is ok, but their projected pricing is just crazy.
$650 for the set with a ChromaPad and $490 without... and you still have to supply your own printer, vs $460 for the Bambu Lab A1 mini with AMS.
Sure the A1 is only 180x180, but it is way cheaper entry into multi-colour printing.
I mean, I'd love to get this instead, and breathe some new life into my old BIQU B1, or even upgrade my K1 to multi-colour, but with the USD at 18.5 to my currency, this is a hard sell.
If the prices remain at the Kickstarter Level, then sure, but definitely not at full price.

[@azimuth9819]

Interested in this for my Klipper CR-10 that only has the frame left stock. I’m reluctant to shell out that much money and the time to do the modification before anyone has had a chance for objective reviews. I guess that’s one of the risks of a Kickstarter. Not worth the discount IMO.

[@bozthescrewup410]

Then why does everyone complain about purge towers and multi color being so wasteful? I’ve literally never seen this mentioned when discussing multi color printing, wether it be mmu or carrot feeder videos or anything newer. You’d think everyone would just do that instead of throwing away huge blocks of purge material and making videos talking about exactly how wasteful multicolor printing is without this ever coming up. Weird.

[@r3fuze]

@@bozthescrewup410 I think it's mainly because of two reasons, the biggest one being people just don't know that it's an option.
The other being the parts you get when printing an object with purge material will be ugly (negative for decorative parts) because of the mixed colors and other defects due to nozzle pressure, ooze, etc., and also weaker (negative for functional parts) due to many of the same reasons. If you're using multiple materials instead of just multiple colors of the same material then the part will be extra weak, possibly totally unusable with the right mix of materials.
Even if ugly and weakened parts aren't a problem then you still need to find a model to print with the purge material. If you pick something too large (relative to the material purged) then you'll use a lot more filament and time to finish the "waste" part. If you pick something too small then you'll need to print multiple of them or you'll end up with a purge tower anyways.
The model also needs to be something usable, otherwise it'll just end in the trash like the purge tower would have, and at that point it hasn't actually made a difference other than maybe wasting a bit more filament.

[@BeefIngot]

I hope they havent done the crappy move of patenting something people have already done for years with multiple extruders feeding into one main extruder like the smaller ercf does and many other extruders do. That would make me hate this company really quickly.

That purge block on the Ender looks like it has more material than the print! lol. I know it's a known evil with multi material through a single hotend....but come on, smh

[@unknownnetworkhub7460]

Did you brother to watch the full video? You can have purge model.

[@nickwarawa5764]

"The model that is printing right now is fantastic." What? It looks like crap with all the layer shifting. I acknowledge this is a startup and a neat idea, but the printing problem should be resolved before displaying this in public.

[@3DPrintingNerd]

live demonstrations of not finished products are super difficult, and I thought the print was great for being on an Ender 3 in Germany on the show floor where it had been poked and prodded by the general public.
Going forward I'll be more careful with my words, since not everyone has had the ability to go to one of these shows and experience it first hand.

[@nickwarawa5764]

@@3DPrintingNerd I appreciate your coverage of these events.

[@PhonePhone-sf8te]

nice idea but that print has so much layershift.

[@3DPrintingNerd]

Sure does. That’s the problem with printing live at a trade show.

[@gamedevai]

For months I have be asking several 3D printer reviewers on RUclips if it was possible to make another 3d print model from multicoloured waste purge material, and no one came back with a defiant answer, several months later here it is.......

[@user-ps9bf1br9v]

that print is bad, why display something so bad... and joel noo that print is bad or your camera have some problems, and why is the printhead kable draging over the print???

[@3DPrintingNerd]

I didn't get to see the print up close until reviewing footage once back home. From a short distance it does look great like I said. I think up close, we see the effects of being at a tradeshow with machines that are poked and prodded all day. My guess is they reprint the castle at the next show.

[@myredeemerlivesakatom2314]

That print looks terrible.

[@stoinercraft6389]

probably just a failed print, they show some other mult-color prints that looks nice

[@VincentGroenewold]

@@stoinercraft6389 Sure, but it's supposed to be a show-model, the actual use-case. :) So, showing me nice prints, but with an actual live process that fails, isn't a selling point.

[@liljashy1463]

Yeah that's what I was thinking. The towers are like curvy

[@SparrowMoonhaze]

I was surprised they didn’t address that at all. The other models looked fine, but it looks like it will take a lot of tuning to get there. And who knows what printer those were actually made on.

[@TeaObvious]

Absolutely, i am totally missing the #AD in the title... Because this is an AD with how many issues Joel simply skips over...

[@awildtomappeared5925]

I don't get why you said that print looks fantastic? it has constanty massive layer shifting all over it, the other prints he showed looked good but the one printing was awful.

[@3DPrintingNerd]

I didn't get a close look at it until back home and looking at the footage. When I wasn't close up, it looked great. I think the issue with the castle is doing it all live. The printer had been at the booth for a couple days already, and my guess is bumped and poked by many. My guess is they reprint the castle at their next event.

[@MakerSpaceDK]

still alot of spill in the purge tower and the fact that it is for an ender 3 seems like its 5 years late to the show.

[@edrompa]

It's not just for a ender 3. It can be used on virtually any printer.

[@tombo7719]

And this is why I always hit Creality because they will copy this along with every other innovation, and then drive the market to the bottom taking out innovation for their market domination. I hope those company has patented the wholy crap out of the thing. Creality and their copying/non-innovation hurts the entire industry.

[@sbvikings30]

This is just incorrect. Although your point is valid from an ip standpoint, this patent mindset is single-handedly the most detrimental thing to 3d printing technology. The advancements we are at today could have been done 10 years ago, but due to patents limiting competition from stratasys and others held back the whole industry. You can't just straight up copy something like this, r&d and testing is still required which imo is the work. The idea is just using existing methods to accomplish a needed task. Competition is a great thing, it drives prices down, pushes iteration, and allows this kind of technology to get in the hands of lower end consumers. Every person into 3d printing right now owes a huge thank you to creality.

[@roundcheesewheel]

​@sbvikings30 yup, i agree. FDM printing would have been a thing 20 years ago if not for patents, imagine where 3D printing would be now

[@1QKGLH]

wow, that ender prints terrible.

[@adilator]

Multicolor 3D printing is a literal waste of filament and time. No one has come up with a decent solution yet.

[@J.R.jr-pc7bo]

Yeah, I agree. I'm surprised there isn't anything where the purge is used on the infill easily. I have seen where it has to be coded into the g-code but for someone who's not heavily software savvy, that can be a difficult task.

[@kimmelmd1]

Prusa XXL, with 5 heads....for $5k, lmaooo

[@Nawjo]

@@J.R.jr-pc7bo you can purge into infill in prusaslicer. Similar to purge into another object. That's all available in prusa slicer.
And solution to purge is multi tool as someone else pointed out

[@harmless6813]

There are good multi-color SLS (laser sintering) printers available. Not at the hobby level though.

[@ScuffedEngineer]

@@J.R.jr-pc7bo It's literally a click box on BambuStudio
