Changing the setting to "interface only" swaps would probably cut those 16 hours down to a 8-9h print. I hope you make an update video after verifying and testing.

[@hasserecht3678]

and the same goes for bambu machines.

[@TheMax107]

Support interfaces should also be 100% it helps alot with the quality

[@CoryTaylor904]

You can't do that because petg and pla do not bond, meaning this method only works when the support material is in contact with the build plate.

[@TheMax107]

@@CoryTaylor904 yes you can do that I do it all the time

[@UncleJessy]

Yup! Planning on testing that out

[@Chad.The.Flornadian]

If you only swap to the other filament for the interface layer then you'll cut down big time on tool changes. I've used that trick on my P1S w/ AMS.

[@envy3436]

A lot of the time the supports fail when doing it this way better to just make the entire support Petg

[@Chad.The.Flornadian]

@@envy3436 If you have a prusa XL then sure. But if you're using an AMS, it's going to switch at least twice every single layer and that will take an obscene amount of time. I've used that trick a few times and I've never had supports fail. I'd rather take my chances than have prints take double the time because of the extra filament swamps

[@pst291]

I routinely do a raft of pla and then switch out to petg and it works perfectly and saves me gluing or hairspraying my glass bed. It works flawlessly

[@UncleJessy]

Ohhh that’s a fantastic idea

[@bernardtarver]

How long does it take to apply a glue stick?

[@francisbeland8959]

Removing support that easy is the best feeling ever. The route I'm taking doing PETG support and PLA print with my X1 and AMS is to print the support using PLA and only using PETG for 2 layers to interface between the support and the part. It's a feature in Bambu studio and it works well. It decrease the amount of poop generated.

[@DUSKtillDAN666]

I'm sure it rumoured that Bambu are working on a printer like this. I'm holding out for that in the hopes that it'll be cheaper than this beast. I so need a multi head printer as I am rather fed up with the amount of waste from my carbon

[@krollmond7544]

For whenever that happens I'm just gonna get the XL, recently been seeing a lot of good things about it. But kudos to the Bambu fans I guess.

[@alexgibson7960]

​@krollmond7544 I've been tempted too, but it's way too expensive for me. Hopefully bambus will be cheaper. I also already have an x1 and a1 so having it part of the ecosystem where I can easily manage them will be nice.

[@krollmond7544]

@alexgibson7960 yeah the price sucks, and I personally don't think the enclosure is worth $600 (like what even lol). It should come with the enclosure THEN I would say the price is worthwhile.

[@ryanmeredith6443]

I routinely rock a PETG support interface layer when supporting PLA on my X1-C for clean removal (or vise versa). But by only using it on the interface layer, there is less waste.

[@olahf8490]

I just put in a order for the Prusa xl 5 toolhead option for my office AM lab and I cant wait to receive it! I am really happy to see the Prusa xl getting some reviews and love. I was pretty apprehensive about ordering this at first.

[@Enjoymentboy]

This shows a perfect case for recycling PETG waste. TBH I'd love it if filament manufacturers would make a PETG specifically for supports like this. It doesn't need to be high quality or consistent colour. It just needs to print and the cheaper the PETG costs the better. In fact using dirt cheap recycled PETG would reduce print costs even more by preventing PLA prints from failing due to bad support settings or supports welding to the print forcing it to be done again.

[@magomat6756]

I have the 5 toolhead and I love this printer

[@andrade175]

I would really like to see you print TPU with PLA/PETG. It's one of the thing that sets the XL apart from the bambu lab, besides the amount of time and purge waste you save, especially in large prints. The xl is expensive, but i think for the right application, it"s worth the money. Great video, by the way! I've been watching for some time, and i enjoy all your content.

[@UncleJessy]

Oh I will 1000% be doing that soon

[@WonkoTSane]

@@UncleJessy I have a proof of concept part that I designed that is a bearing mount of TPU inset in a PLA or PETG case that I can send you. It is a fairly quick print.

[@Repkord]

Glad your first big print came out so well. Super fun to watch that tool-changer work right?!

[@UncleJessy]

Thanks again for the help man! Was a fun build

[@anmolsinghshekhawat4284]

may be you can somewhat get rid of some filament infusion by using similar colour filament it would certainly hide some of those imperfections

[@06TundraLTD]

I pre-ordered the 5 head, it's been an awesome printer

[@hasserecht3678]

you can dramatically reduce the purges by just using petg as interface-layer-material on a bambu machine.

[@offearth3d]

What a clean print. Need to do this with HIPS & ASA

[@RaySchrantz]

Also you don't have to worry about jamming when swapping between materials that print at different temperatures. I'd love to use PLA supports for my PETG, but in my experience you're more likely to jam because of the temperature difference or spend a lot of money on HTPLA to reduce that risk and waste a lot of it switching materials. At that point you might as well go for a soluble support.

[@Ferrous_Bueller]

They’re insane asking those prices in this market, especially considering we’ve had successful dual tool head printers for years. Prusa be smoking something good 😂

[@robh9442]

I tried PETG for print, PLA for supports with various results (PLA+ too if trying to match heat better). When it works, it's great. When it doesn't, it's a mess. The general thing I noticed is if the print material contacts itself (the main body), it works very well (like how the mask mostly prints) as it also gets some support from the main body. However, if the print material is floated on top of the supports without contact with the main body, then there is a higher risk the print material will come of the support and make spaghetti.

[@SuperheroDIY]

Man this is exciting!

[@Dan_Murphy]

I actually just printed something in tpu and used a ring of pla for support material that i designed in fusion with zero tolerance. It worked out great because they dont stick together, and the support surface was perfect. Unfortunately i dont have a dual toolhead setup like this, lol so i could only have the ring go up so high so it didnt interfere with the fan ducts and cr touch.

[@DaisyLee2002]

That came out great!

[@cheetahkid]

To Uncle Jessy, Purging, oh wait, there shouldn't be purging, I have to say out loud "NO PURGING", you know why, I run IDEX printer and never used purging at all. Try it out yourself. Maybe a little if you don't have a tray or a scrubber.

[@iain-0]

I really wish my p1s had a 2nd print head. I do a lot of minis and terrain with thin layers. They need a lot of supports and don’t always come free clearly, but the amount of waste just swapping for interfaces is crazy. Like many times the amount used for the print. I’m sure this comes from the small layer sizes and relatively low volume of the print, but the AMS system is completely impractical for this use case

[@wl7291]

You can also do tpu with pla as support material. Modbot did a video a while ago. Could do cosplay props horizontally to make them more durable

G'day uncle Jessy..... could you show a duel print with PVA Filament as support. To show after print you can just dip it in warm water, and have it dissolve the supports leaving a clean finished product without the chance of breaking a piece of the model away. There a lot of people who dont know of this way of printing with supports of PVA filament. Cheers from one of your Patreon members, A M8 Downunder🙃

I was thinking while watching about the stringing from the PETG getting into the PLA. That could be what happened with the upper eye.

[@Return_To_Sender]

Been using support interface layers on my X1C to do PETG/PLA & PLA/PETG prints. It saves so much time and purge materials. I don't know what slicer you use but in bambu studio, it's super easy to do. Definitely check it out.

[@dehdeh6143]

The whole problem imo is that it saves anything but time. It takes ages longer with a different support interface.

[@Queue22]

you wont catch me using Multi Material prints unless its multi tool heads. I cant justify the bambu waste

[@3DJapan]

What's the benefit to PETG here? Why not just all PLA?

[@UncleJessy]

They don’t adhere to each other so the supports remove super smoothly and don’t leave scaring / stick to the prints. You could print supports in PLA and the object in PetG as well. I need to experiment with just using this for the interface layers as well

[@3DJapan]

@@UncleJessy Thank you.

[@scott3001]

I think it's a way better solution to have entier supports printed in PETG here, because printing just a tiny layer (or several) in PETG between PLA may just create 2 week interface instead of one and may result in a mess. That's what I did several times on my Bambu, and every time there are chucks of interface material that come loose and ruine my print. I think I will change my Bambu to a Prusa XL soon.

[@EmbIazon]

What was your Z distance between support and print set to? Should PETG be used in the same manner as dedicated support material?

[@Eewokney]

why does it have a purge tower if you are using different nozzles? why does it have to be purged? might it be there to build the pressure in the nozzle before printing and to catch any oozing that has happend while the tool was parked? so it would be a prime tower instead of a purge tower? Also i see the whole tree support being printed in petg, even in layers where there is no supporting of the model happening, is it possible to use a support interface layer and only have that as PETG? then you dont have to switch toolhead on layers that arent doing any supporting and you wont have to prime the nozzle on that layer. Increasing print spead and reducing the little bit of prime waste.

[@logicalfundy]

It's a prime tower to get the filament flow stabilized, Bambu does the same. To answer your question: Yes, it is possible to set it up to only use PETG for the interface.

[@rigas84]

Im going to be getting a Jupiter SE for Christmas and wanted to ask what the biggest (budget) wash and cure station I should be looking at?

[@korriehusky8404]

The Presa XL looks nice and 5 different tool heads sounds great. But the price is crazy, also I could see the Prusa XL tool head system having some issues especially if the printer tool head isn't lined up correctly or the part that selects the tool head is off. Plus what if you are running different filaments that require all different templates? Also I am sure I have seen videos of a product that does this I believe it is called the "Carrot" so there is no need to buy a new printer. Plus it doesn’t offer the and latest topic of multiple hotends printing at the same time with could really change the game. We all know that Bambu Lab will release a new printer that is similar if not better. As well as a way to upgrad current printers to have multiple tool heads. Just imagine 5 tool heads, all 5 hooked up 4 AMS system. So 20 AMS systems allowing 80 spools of filament. Even though Bambu Lab AMS systems max is 16 that isn't really true since if you keep splitting off the adapters that feeds the filament to the printer you can run as many as you want. Only issue you might run into is a power supply but that could be easily fixed if they release a power adapter.

[@harperbrett]

For this setup, could you have different sized extruder nozzles on each print head? For example, a 0.2 mm nozzle for fine detail and a 0.4 mm for structural components?

[@chrishuefner7989]

Would you recommend the prusa xl over the creality K1 max?

[@RusselJauregui]

ton of filament? just add a purge object and you get two prints on bambu

[@oneillam1990]

support interface is the only layer that should be a different material

[@TheNewBloodDan]

PETG prints with PLA SUPPORTS IS BETTER! PETG FTW!!!

[@krunchy3761]

PETG pretty much won't stick to anything except PETG - so it will work as support for most common filaments. You can also just use it on the interface layer; I don't really see the point unless you want to save more of one filament. Full supports are nice if they need to make contact with the main piece other than just at the top. I've used this on my Bambu X1C and my Snapmaker IDEX.

[@darren990]

i like that blue

[@Kirky64]

Other than the bigger print volume, the cost difference between the Prusa XL with 5 print heads and a Bambu Lab P1S with an AMS is $3,150. So the real question is, how long would it take to build up $3,150 of poop from the Bambu Lab to justify the cost of the Prusa XL?

[@UncleJessy]

That is very true. I think time would also have to factor into this as the multi color prints on the xl print a good bit faster than on the Bambu machines

[@Kirky64]

@@UncleJessy I was able to find a Doctor Doom mask (not the same one you were printing) and with PETG as tree supports, it would have taken over 2 days to print. I'm guessing with the XL it is about a 5-6 hour print? If you had to mass produce stuff that needs perfect bottoms everywhere, the XL does make sense, but one offs, I would learn to be patient for $3k, lol

[@peterdocter4659]

CHALLENGE: Make PET filament from a pet bottle (water or soda or something bottle), then use that filament for the supports., and print something.

[@Unreal_Editor]

Is it possible to multi material print on an elegoo neptune 4 plus by pausing printing swaping filaments and resuming printing?

Well waste of money depending on the point of view, can you buy any other commercial toolchanger 3D printer for this price? You can’t .

[@OurHeroXero]

Depends on how much you print/use multiple filaments and how important reduced print time is. Filament waste adds up; so the less you waste the more you save. Quicker print times translate to more sellable items in the same amount of time.

[@TheOneAndOnlySatan]

That’s not true in both cases. You can achieve the same, or even better, results with something like an SV08 and a commercial MMU for a fraction of the cost. It’s more reliable, offers better support, and retains its value, whereas Prusa locks you into their ecosystem at premium prices just for the name. The XL doesn’t even come with an enclosure, essentially making it a PLA printer. Plus, it’s so "advanced" it doesn’t even need an accelerometer for input shaping, so fast printing-like a fast-moving print head-is out of the question. Sometimes it feels like Prusa is a cult-people think it’s the only option and just blindly pay up. Look at the MK4-still using 2016 tech, no camera, and it’s $1,100. Don’t get me wrong, I had a Prusa in '17, sold it in '20, and went with Voron.
