Sometimes supports are very difficult to remove physically when I print with ABS. I've learned about polyvinylalcohol PVA as a 3D-printing filament which is soluble in water. It seems like a great option for dual-extruder printers, where you can print the model with ABS or PLA and the supports with PVA, then throw the whole thing in water and let the supports dissolve.

When you print with ABS or have complicated interwoven support structures, HIPS can be dissolved with D-limonene, a citrus based cleaner sold under various names like Citrisolv others existor with dipentene a mixture of L and D-limonene that doesn't smell as pleasant. Additionally, it isn't hydroscopic in the same way as PVA so it lasts longer out of the package. Since you're using it as support, you also tend to use far less filament than you do for the main print sparse support structures as opposed to solid print structures.

These are usually very expensive and you'd have to rewind the filament on a spool, as they come in cartridges made for specific printers. You'd also have to experiment with the right build conditions and solution blends to remove the material afterward. Airwolf has a support material called Hydrofill that purports to be soluble in plain water… I'm not sure how this is different from standard PVA, though I assume it is different.

Hopefully more companies will work on developing water-soluble options to help us keep the 3D printing world full of renewable, less-environmentally-harmful options for filaments both print and support. Ultimaker now has a material called Ultimaker Breakaway. After using it for a few models, it works remarkably well, allowing me, for the first time, to print nice rounded surfaces on the bases of my prints. I haven't tried this myself, but the recommended way I've seen for dealing with the high cost of PVA is to print the support structure in ABS, PLA, or something else cheap, and print only the interface area the top of the support where it meets the model in PVA.

I have no skin in this game. Aspects that may carry forward to non-MMU2 machines include:. This is not a negative review of the filament itself, or of the Prusa i3m3-MMU2. I may be doing something wrong, and would love to know better. This is the result of launching into soluble support, which is a feature I strongly hope to use reliably.

Not sure if frame challenge is on-topic here, but have you tried using different support options in your slicer? In Cura, I've found the experimental support tree mode both reduces the material usage a lot and gives supports that are easier to remove, at least for geometric vs "organic", where it's sometimes good and sometimes bad models.PrusaSlicer is a feature-rich, frequently updated tool that contains everything you need to export the perfect print files for your Original Prusa 3D printer.

PrusaSlicer is available for Windows, Mac and Linux. Get PrusaSlicer now! Download v2. Full release log and the latest unstable builds on Github. PrusaSlicer is based on Slic3r by Alessandro Ranellucci. It's completely free and open-source. Thanks to the strong community and core team of developers in Prusa Research we can continually add new functionality.

You can follow the development process on Github. Slic3r was always known to be powerful and versatile, but some features were difficult to use, if not outright hidden behind obscure menus and dialogs. Our goal with the reworked UI was to expose all the power features while making the UI clear and simple to use at the same time.

About the Product

PrusaSlicer lets you create support blockers and enforcers. With support enforcers, you can turn automatic supports off and select specific parts which need supports. We are adding profiles on regular basis, following materials by the most popular manufacturers. You will get new profiles automatically through auto-update function.

In PrusaSlicer, you can select the layer height for each part of the object separately. Our software takes care of smoothing so the final print looks best as it can and the printing time remains acceptable. Check out the video. PrusaSlicer includes built-in firmware flasher for Original Prusa i3 printers. You can just connect your printer to computer via USB cable and easily flash the firmware via PrusaSlicer.

Found a bug? Let us know on Github or via community forum.Our first 3D printer enclosure became incredibly popular — and naturally, once we released our new Multi Material Upgrade 2. If you have no experience with 3D printer enclosures, let us give you a quick tour of their benefits:.

Prusamentwe highly recommend keeping the front door partially open to give the nozzle or more specifically — the heatbreak enough airflow for sufficient cooling. High temperatures combined with PLA materials can lead to partially clogged nozzle. Increasing the temperature around the printer and creating a stable environment inside the box will improve the bed adhesion and prevent layer warping. Either way, you will certainly appreciate the compact configuration of all the components.

Plus, the size of the Lack table is pretty much ideal for our 3D printers. What if you already made an enclosure? What if you already paid for the acrylic panels?

Hello, how can we help?

Instead, we decided to modify the original concept and improve it. All printed parts are different, though. On the other hand, the enclosure comes with a number of useful new features, such as a semi-automatic locking mechanism of the lid, magnetic hinges and a small compartment for various tools. The primary goal was to design the enclosure in such a way that anyone will be able to build it at home, using printed parts, regular fasteners and easily accessible materials in general. Non-standard elements are kept to a bare minimum.

So, those were the challenges we had to overcome. Now for the benefits of our solution:. We recommend printing the plastic parts with PETG filament — e. You can use our pre-made G-codes, which are already tested and, of course, sliced with the optimal settings. Or download the. Several parts come with a mounting bracket, that will help you position these components and secure them in place.

Please, do not remove the mounting brackets before you secure the parts in place. However, do not forget to remove the support material, so the parts can be put together.

An In-depth Look at the Prusa Multi Material Upgrade 2 (MMU2)

You need to decide whether to remove the power supply from the printer outside the enclosure or leave it on the printer inside the enclosuredepending on the intended use of the machine. In this case, it is advisable to place the PSU outside the enclosure. On the other hand, leaving the PSU on the printer will make it easier to remove the printer from the enclosure.

Have you decided to keep the PSU inside the enclosure? Skip the next assembly step. Otherwise, follow the instructions below. Turn it upside down, so you have access to the underside light brown color. Use a ruler and a pen to draw a rectangular shape with the dimensions and placement based on the photo above.

Take a snap-off knife and a ruler and start by cutting a rectangular opening. Take the printed parts and put them around the opening to prevent the paper infill from falling onto the printer.Return to Forums Home. I don't own that unit at the moment but I know people who are using the system and I talked a lot with them about the unit so I will share their experience also with you.

It can print with up to 5 materials. It can only be used with a Prusa printer out of the box.

Firmware is open source so in theory you could tinker it to work with other printers. Prusa has also their own open source slicer called Slic3er PE.

The Palette 2 comes in two versions, the standard and the pro. Both versions can print with up to 4 materials. I highly recommend the pro version because it has a better warranty and comes with better quality parts.

I also recommend the canvas hub option because it makes it easier to connect the system to your printer. That would result in a total prise of USD. The Palette 3 can only be used with 3D printers that use 1. So it can't be used with something like an Ultimaker. One more thing about filament. Prusa has now their own filament called Prusament. And you get a QR code with your spool to check the measuring yourself.

One and only advantage of the 2. If you are using 1. That is mainly thanks to the Bondtech direct drive extruder. One other nice feature is the removable magnetic flex steel PEI bed. I guarantee you that if you are using this feature one time you will never never ever want a printer without it again.

The basic principle of the system is that it adds a bowden system with a selector to the direct drive system. So the direct drive system pulls the filament up until the bowden system takes over. Than it switches the filament and the bowden system pushes the filament back to the direct drive gears.

And so on As already mentioned it comes as a kit. And that is a BIG problem. Assembling it is not easy because you have to make sure that the filament path is as smoothly as possible. When you pull filament out from the hotend you can have tips with large strings or increased diameters. That will cause problems.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Tested and recommended as soluble supports for our Multi Material upgrade. I also asked this question in Prusa mmu2 forums before coming here 2 weeks ago no answer. Can I reopen this im am trying M3D water soluble in the mmu2 it loads fine but the ir filament sensor does not detect the PVA and will make a big blob on the purge tower.

Your problem is most probably hardware related IR calibration. PVA filaments are often very soft like flex which means, that idler door will open slightly less after loading the filament. Also check your idler tension. Skip to content.

I have a filament setup in slic3r, I can get it to use the soluble filament for supports. But how to i get it to only do soluble supports at the interface layer?

The video for the MMU 1. Any help would be appreciated. It's under "Multiple Extruders" in the Print Settings. Perfect thanks! I also see today there was a config update for slic3r and they have added the soluble print settings back in. Can I ask which brand of soluble pva did you use? Did you have to modify the verbatim profile? How did your print go? Any issues, concerns? I have two rolls of primaselect but dont see a profile in Slic3r, only a profile for verbatim pva.

It worked fine with provided profiles for about 6 hours and then started to string - but it was quite humid at the time.

Apparently is can be OK for up to 2 days! Biggest issue for me has having to keep the BVOH print temp high to make it stick to itself while keeping stringing minimised. I'm trying to use soluble supports PVA in extruder 5, but as soon as I select it, the Wipe Tower settings are disabled.

Why are these two settings mutually exclusive?

How is it not going to make a wipe tower with 5 different filaments? Its a separate printer profile. Then you'll able to choose soluble support for interface layer and assign it a certain extruder. Ah, gotcha. My Slic3r just updated and now I have those new profiles. Makes sense now. I hope it doesn't string like crazy. I also don't have my MMU 2 yet hoping it arrives in a couple of weeks if the shipping schedule is still valid.

I was wondering whether it was feasible to run any manual filament unload tests prior to receiving the MMU to try determine whether filament stocks like PVA already held are likely to work without too much unload stringing etc?

We have just started shipping the MMU 2. August was a pretty tough month! Not only because of the awful heatwave in Prague but mostly because we had to wrap up so many things.

MMU 2. It was a huge commitment — after all, the preorders are reaching almost You can order your own Multi Material Upgrade 2. But remember, new orders will not be shipped until November. Follow us on Twitter to get info about the shipping table updates. Right now we are shipping orders from the first 14 days. Anyway, the result is amazing. What we have here is a one-of-a-kind multi-material printing addon that is fully integrated with the printer, so everything is perfectly synchronized and the whole thing works seamlessly as a single unit.

Plus, our MMU 2. We wanted a simpler, more efficient design. The unit was completely redesigned. We have added an automated filament-cutting blade and also physical buttons for manual controls. We have bumped up the number of materials to five, decreased the number of extruder motors to one and got rid of multiple Bowden tubes, which proved to be problematic — there were issues with flexible filaments, proper retractions, and other things. Overall, the MMU1 was quite picky regarding filament quality.

So instead, the new MMU 2.

We know that the original multi-material addon was prone to jamming also because of the Bowden systemso we decided to fix that. The selector has a built-in blade that will cut off the filament tip if it gets stuck during unloading. As a result, the new unit is less sensitive to the filament quality, and jams should be a thing of the past now!

An important part of the selector is the F. When you insert a string of filament, it lifts a small stainless steel ball. Then, the probe detects its proximity, which means that the filament is loaded. We also wanted to make MMU 2. Obviously, a large part is completely automated, but you still have some control over certain actions. We placed three buttons at the top of the MMU 2. The buttons also have some advanced functions.

For example, you can use them to calibrate the length of the PTFE tube. Everything is thoroughly explained in the assembly manual and in the handbook.

Yes, the assembly manual — the MMU 2.
