Hi @thomas_nomad, The print profile is only available for Ultimaker S3/S5 printers, see here for 17-4 PH: https://marketplace.ultimaker.com/app/cura/materials/rlsijlbing/Ultrafuse17_4PH And here for 316L: https://marketplace.ultimaker.com/app/cura/materials/rlsijlbing/BASF_Ultrafuse_316L If you'd like to use it on another printer, typically you can also look at BASF or a 3rd party printer if they have a print profile for the material and printer you're using. Good luck!

@glx Best to reach out to the material supplier themselves with those requests, they make the profiles for their materials on Ultimaker printers. Maybe also specify which printer, printcore and layer height. See here for contact information: https://marketplace.ultimaker.com/app/cura/materials/InfiniteMaterialSolutions/AquaSys120 Hope this helps!

Hi Andrew, Thanks for sharing the 3mf file. It looks like you're using 'tree' support, did you also try 'normal' support and does it give you the same error? On Breakaway: Breakaway is great if you don't have support inside your printed part (and PLA can typically handle most overhangs quite well - so this might be possible). This might help you out for this model, and post-processing is much faster.

Hi @cfcabrera, Let's see if we can help. First issue: BASF Ultrafuse PET amount of filament. So only Ultimaker materials with their NFCs are able to recognize the amount of filaments left on the spools. For 3rd party materials this is not possibly unfortunately. If you'd really like this feature, I'd recommend switching to Ultimaker PETG instead. Second issue: this is a bit more difficult, maybe check on our support pages for your specific printer what issue you have. Good starting point is here: https://support.ultimaker.com/hc/en-us/articles/360016971619-The-material-failed-to-load-wizard Hope this helps!

Hi @Andrew_W, Interesting, can you also share a 3MF file of the project? Then we can actually see what settings you're using. It looks you have a modified PVA profile (?) and possibly a lot of small retractions / oozing that might cause these issues (from what I can see based on the ufp file). From your youtube movie, it seems to be a a bit of moisture in your PVA that is bubbling during printing.

Hi @Siggir, You could try to look here for a chemical resistance 101: https://ultimaker.com/learn/chemical-resistant-materials-a-beginners-guide If you're looking for HDPE, the next best material which is reasonably printable is PP. I'd guess giving that a go might work (although Ultimaker PP is a bit more flexible as its an PP-PE copolymer). If you need something stiffer, you could also look at a Marketplace PP / PE material: https://marketplace.ultimaker.com/app/cura/materials?page=1&polymer_classes=pe,pp,polyolefins. Apparently Braskem has a HDPE-like filament with a print profile for the S5 available: https://marketplace.ultimaker.com/app/cura/materials/1234567/FL300PE Hope this helps!

@Andrew_W: Thanks for the picture. I guess this is UM PVA and UM/3rd party black PLA? What is your main issue and could you share a 3mf file?

@rachael7 Thanks for sharing your experience here. To be honest, for us the brittle PVA in the Material Station was also unacceptable, we actually had a crash team working from multiple angles on this for several months - we definitely did not ignore this. For the other readers, check here in case you're interested in what we've done: https://support.ultimaker.com/hc/en-us/articles/360015621060-PVA-material-breaking-in-the-Material-Station. So indeed, the brittleness is improved directly at the production location, and we design a feeder wheel with finer knurls to not damage the PVA. Our coarse feeder wheels apparently create a starting point (craze) for brittleness. We are still actively monitoring if we see issues coming up like this, and I can imagine transportation to specific sites with higher temperatures might indeed lead to brittle PVA. Did you report your experiences to our customer service? Can you also share (roughly) where you are located?

@MobyDisk: that is true, especially in winter the moisture content in the air is relatively low, especially if you print in a room with heating. To give you some insight: typical office environments have 50% RH at 20C in spring / autumn (summer can be a bit higher ~60%, and winter really depends on how cold it is outside). Anyway, let's take 50% RH at 20C, if you heat up the same air with the same moisture content, your relative humidity will go down to only 10% RH. The point is that RH is kind of the 'active' moisture and this determines the moisture uptake of your filament (not the total gram water in air). So for getting wet filament and/or drying filament RH is the key parameter to focus on. Increasing temperature helps in enhancing diffusion of moisture from within the filament to the air (basically speeding things up).

@gr5: So about Nylon you're absolutely right. There is no problem in drying Nylon at 70C. If you dry Ultimaker Nylon transparant, you will see it become a bit more milky (crystals formed in the filament). Also, the filament should be a bit stiffer. For printing, it doesn't matter that much since you melt the filament again in the printhead, so the Nylon crystals get molten anyway. That's the tricky part about PVA. About drying, two main considerations: - Heat: this reduced the relative humidity and enhances the moisture diffusion through the filament (especially close and above the Tg of Nylon / PVA 50~60C). - Convection: by having air flow around the filament you remove the moisture coming out from the filament. So indeed a tightly spooled filament coil will take up moisture on the outside first, but will also dry on the outside first. If it's moist also on the inner filament, it's more difficult to dry those parts as well (unspooling or loosening it up can help - so at least some air flow can reach the inner filament too).
-
@Andrew_W: We recommend to dry the material at 50C, preferably also for longer times (overnight). Additional benefit is that this should relax stresses in the material, leading to reducing brittleness. The trick is with PVA to dry the material without crystallizing it, PVA is a semicrystalline material, and will crystallize when heated over 55C for longer times. Crystalline PVA will become stiffer and brittle, so that's also undesired. Moisture will lead to enhanced degradation during printing (e.g. the 'sugar crystals' you are referring to). Luckily, Ultimaker PVA doesn't absorb moisture as fast as other PVA filaments. In addition, there are no additives in Ultimaker PVA, which makes handling a bit more difficult but it is safer to print and easy to handle the water which was used for dissolving PVA (this is always a trade-off in soluble support filaments - it depends where the manufacturer focusses on). Hope this background information helps a bit!

@RoLa: @gr5 So with Ultimaker Nylon Magigoo PA works very well with the default profile (70C build plate temperature). If you do still have a lot of warping, you can also lower the build plate temperature to 30-40C, this will stop the Nylon from crystallizing during printing ( = warping / bending what you describe). However, the Nylon part will get a bit more flexible this way (depending on your application this might actually be desired). Ultimaker Nylon is PA6/66 by the way, and it melts at ~190C.

Ehm I'm not sure if you're talking about the printer itself or filaments which fulfill the EN45545 standard? If you're looking for filaments, I believe there's a FR LS EN45545 filament on the Marketplace by Covestro: https://marketplace.ultimaker.com/app/cura/materials/jmarguier/Clariant_PA666GF20FRLSB Hope this helps?

Like @AndersK said PVDF. Or a non-fluorinated version like PP might do the trick. It really depends on what kind of chemical agents are being used - please check this one where we put some common chemicals vs materials in a table: https://ultimaker.com/learn/chemical-resistant-materials-a-beginners-guide Other options could be: - Arnitel TPC (like a PETG but softer and more wear-resistant like TPU) - Nylon (something with PA66 like UM Nylon, which is wear resistant - however it should withstand the chemicals too). Hope this helps!

using breakaway material for parts
TimonR replied to Jman15x's topic in Design for Additive Manufacturing
@Jman15x: that is indeed not the intended use for Breakaway. Breakaway is mixture of PLA and TPU (it's in the SDS for Breakaway), which gives it an ideal combination of sufficient stiffness to supports parts (unlike TPU) and allowing you to properly tear it off (unlike PLA - which would be too brittle). So I guess it should give you some interesting properties somewhere between PLA and TPU.
