I'm not a fan of the wasteful purge blocks. I think purging as infill or a purge bucket would be less wasteful and probably also improve print time.
Would love to see your thoughts on the Lulzbots several years down the line, things you’ve found to improve your prints, settings that helped etc.
It's incredible how fast 3D printing innovation is taking off! I can't to see where the tech lands next quarter!

Genius software and hardware!
I kinda imagined this exact thing. cool. now it should just make it somehow super exact to forego the need of the purging.
GREAT CONTENT, my friend you deserve more 👍👍
The Purge blocks look cool!!!!!
When mixing types of filament, say PLA and PETG, does it pause for each switch to adjust the hot end temp?
I haven't actually tried it yet, but it'll handle it somehow. There are different splicing settings in various categories for the actual splice between different materials though.
@@jamesbruton please do a follow up on this topic. I am really interested in this.. wondering if different material types will stick together properly
Great question. I'd also like to see a follow-up video once you've got to grips with all the ins and outs please, James.
That’s so cool!
Could you do a flexible / non flexible composite material? as in make an interleaved material using a stiff and a flexible filament to create a material that behaves like a mix of the 2? I am thinking of situations where you might want a stiff leg that has a soft flexible bit at the end to better withstand impacts or bends or a finger that you want to be stiff at the core but have a soft surface that can conform to complex surfaces
Do you think it will work with flexible materials? I was thinking of building a dual extruder printer but this looks way tidier
Interesting video 👍
Thanks for sharing 👍😀
This looks awesome. I run 3d printers with high school kids and have students of various skill level using them. How dependable is this system? Also is there a way to easily bypass it in case it is not needed / causing problems etc?
Does this work with infill purge where you purge the filament in the infill so you dont get as big of a purge tower
Nice. I thought about getting a Palette when it came out for doing PVA, but even with intermediate supports it wastes a whole lot of filament with purging. On a plus side, having multi in and 1 out is a whole lot more precise than the dual extruder I have which alignment issues are hell.
what is your printer?
@@Blackmorenightfrance T-Rex 3
BigBrain3D has a system that only purges when necessary with the benefit of not creating a purge tower at all. It does small blobs into a bin attached to the side of the printer.
Can it learn how long it takes to get the new color in the nozzle and splice it accordingly, avoiding the whole purge tower?
Nice.
whenever "online" is mentioned, I gag... but either way, this seems like an awesome piece of kit!
Just the technology in this thing is amazing! I guess it costs more than a printer.
Don't know the price-ratio, but it being costly makes sense, the printer itself "just" moves the extruder head and feeds a single material. The add-on has to work out how much and when it needs to splice in the different materials, which is complicated as it needs to know *exactly* how much flow there is, or the splices will be in the wrong places. A multi head printer would probably be better as the heads could be at different temps and you wouldn't need to fear the splices coming in at wrong times.
Well if you start with a bottom of the barrel printer of course it’s going to cost more.
@@StuffWithKirby what 3d printer would you recommend for begineer?
@@streamx2 As much as I hate to say it: for most people an Ender 3 is a good pick
livelifetothefull I prefer my Lulzbot printers. They’re reliable and dont need any modifications out of the box to start printing.
Don't know how practical it is, but $800 seems awfully reasonable for the amount of stuff going on in that enclosure.
I do like how both the Canvas and the MMU basically do the same thing and face the same problems and both work without printer modifications, but do things quite differently.
The Canvas does the splice then feeds it down the tube and has to leave enough to purge, the MMU does the 'splice' in the hotend..
I wonder what is the most reliable in the real world longer term. And of course this changes as software and hardware evolves. :)
3D printing is such a technical process, sorry if this is pedantic, but if you're referring to the Prussa MMU I think this could be misleading. 'Splice' of filament makes me think there must be a bond between the two materials prior to printing. That's not the case with the MMU (and in my opinion one of the biggest advantages over the Palette). Each have their drawbacks but I think there are just less variables when different filaments need only bond in their final location vs within the machine and on the build plate. My MMU is tricky but a great performer. That said, I am jealous of that stamp feature in Canvas.
@@planckstudios I should have used 'merge' maybe. The only missing step really is the cool down stage. The Prusa MMU retracts, leaving a little bit inside the hot end, the new filament goes in, merges with the old and that is then pushed out with the purge. It still has the problem where one colour has to push out the next. But you are right.
I'm sure the 'stamp' feature is something that can be added fairly easily as it's purely a software thing, it's the different hardware approaches that I find interesting to compare.
@@ElectraFlarefire def an exciting time to be making stuff :) have you seen this approach? www.reddit.com/r/3Dprinting/comments/g2dwpg/my_medusa_multi_material_prototype_satisfying_to/
Does it support purging to infill?
Yea want to know this too! This is the biggest development that would be so important to me for multi color prints. Can't stand the idea of that massive Purge block.
Great
will you ever make another bb-8?
Why would he?
Nice😘
What cad software would you recommend at a low cost to design these parts?
Fusion 360
He uses Fusion 360, which is free for students and hobbyists
Thanks to both of you :)
@@ericlotze7724 That is a good choice as well. Thank you :)
What happens if I keep negging my splicer?
Make an art piece of the worst prints. Neg it over and over and over, I'm sure they will turn out looking very interesting!
If you have a dual head, can you run two Pallets?
Depends on the software, but probably not as I think this is meant as an upgrade to single head printers.
@@Woffenhorst I don't see why you wouldn't be able to from a technical point of view, but somehow I doubt the software is configured to make sense of it.
If you can get the software to deal with it though, 8 colour printing might be plausible...
Wait ... something doesn't make sense: If it is splicing the filaments so a continuous, multi-colour, string is being fed into the Lulzbot, why does it need a purge tower?
It's because it's really really hard to predict exactly how much each material flows through your nozzle. If it's a tiny bit off with one color/material it could mess up the rest of the colors on the print as it continued. They get around this by having a little bit extra filament to work with that then gets purged out. Also I'm not sure if the splice technology gets rid of any bleeding effect between the filament at the splice. This is just my understanding of it, take it as you will.
By the looks of it, once extruded a splice becomes a gradual blend of the two colours, but what you want is to print with one colour (purge the blend), then print with the other colour.
We are getting closer to printable devices with built-in electronics 😆
This is actually insane. I havent seen this feature on any other printers, is this a first James?
no this tech has been around for a little while. this is the palette 2 after all
There are open source methods too.... Palettes is expensive and limited for certain aspects but it's a good machine
This isn't a printer feature. The Pallette 2 is a stand alone device that realistically can work with any printer at all.
Why am making compromises using this vendor. Luz bot is my printer
This is a great product for business to prototype because the waste is investment, of for wasteful First Worlders hobbyists, where the cost of living is so high that Kilograms of plastic are only worth 1-2 minimum wage work hours. Try that in Brazil, where a spool of PLA costs 1 week's minimum wage, and the machine itself costs 1 year's minimum wage.
Now you can print a dalmatian robot dog 乁[ ◕ ᴥ ◕ ]ㄏ
If they only could purge the nozzle inside the part
So could you use two of the palettes on a dual extruder printer and get 8 color options?
Neat tool but the always online IOT bullshit is really unneccessary. There's no reason for the slicer and the print controller to be seperate systems which have to communicate over the internet. Having a raspberry pi open to the internet on your network like that is just asking to get hacked.
The slicing software could just run on the little control box as the slicing is probably done on the browser, not the server.
It's not open to the internet - the Pi makes an outbound connections like any other home IOT device.
Do you include the 3d printer files for the things you build? Or would I be able to pay for them ?
85th!
1:47 Not true. Capricorn tubing claims (although with a possible reduced lifespan) to withstand temperatures up to 300°C. Although they recommend to have the area well ventilated cause the tube will release toxic gasses.
They promise it will definitely work up to 275°C but at may be not safe to be around.
And up to *250°C* they say it will work and will be safe.

Ya but that's Capricorn not ptfe
@@macus320 it is the same.
I like the idea but out in the real world I think people will struggle with it.
James is ok, he's got a huge knowledge with 3d printing but 'Joe average' will get frustrated with the amount of variables there will be with setting this up and ironing out the issues of their prints.
Third
Dont you waste just as much as you print tho ? , is it me or is there huge waste doin it this way ,,,,,yes its awesome as hell but is it really worth it tho ?????
Yes, the purge tower is wasted material.
If you print a small part (like that coin with the "xrobots" text) in 2 colors you waste a lot.
But if you print 5 of them at the same time, the purge tower does not increase, and you reduce 5 times the wasted material. If you print several parts at a time the problem is smaller
Not sure about this one but the prusa MMU can do purge to infill so not wasteful then.
I'm a maker myself and I don't want to sound like a killjoy but with the popularity of 3D printing rising, where is all the waste from tests going ? and prints that people do just for fun and end up in the bin or our oceans....just a thought.
I really feel with the amount of failed prints and stuff like purge towers, more work needs to be put into home filament extruders.
Apparently it's a difficult problem, but it would solve a lot of issues with waste if failed prints could be recycled into filament.
(even if recycling say, a purge block will create a nasty filament with no clear colour, since it's a bunch of different things mixed together...)
Bonus: You can do things like print in PET, which is a widely available general 'waste' plastic, which people likely have a ready supply of anyway (depending on your buying habits of course.)
Splicing dissimilar material should like a headache.
Typically the content is good on this channel but that really felt like I just watched an extended advertisement.
Well Tuesday videos are unaffected - miniDog does walking quite well on Tuesday

At 800$, I will pass.
Can this device also be used without creating accounts or connecting to the internet?
I'm so frustrated with companies thinking it's a good idea to tie hardware to accounts and servers, when there is abso-fricking-lutely no reason to do so.
It's such a shame so many companies these days f up their good ideas and ingenious inventions by adding a binding to the internet. They spend extra efforts, extra time and money only to do something nobody would need.
But I guess that happens if you let a bunch internet-millennials and webdevelopers start hardware firms.
Totally annoying.
Let me put it simply for anyone unsure out there:
Hardware is not software. Hardware does not need external services or server-connections to do it's job.
Yes, the cloud meme has gone too far. There are already examples of products which have effectively been bricked because their essential online services have been discontinued.

You dont need the cloud for this. You can configure your own slicer to work with it and use chroma to make the gcode. You need the cloud if you want to use their canvas software since it is web only. The palette works fine with no internet.
James! I don't know how far you are with joint design but I just saw this design from a Russian designer and he's explaining exactly how it works and it looks like an interesting joint design for the Sonic robot!

Back-driveable, zero backlash with mechanical advantage.
3 mm standard filament size? absolutely RUBBISH design choice
Drum bum quite a few industrial printers use that size. Lulzbot, Ultimaker, BCN3D. Also its easy to change to 1.75
Sorry this does not work on so many levels
