  1. Hi, I am working on a project testing material resistance to aviation hydraulic fluid (Skydrol/Hyjet V). I am looking for recommendations of materials which may have some resistance to such a chemical. I know that GF30-PA6 fairs well when exposed to these chemicals but equally that materials such as ABS and PLA degrade extremely quickly. Any material suggestions or data sources would be greatly appreciated. Many thanks, Soph
  2. Hi, I need a cura profile for printing um tpu 95A with support by my um3!! Thank you
  3. I know it's a bit of a craze, but I would like to try out some gloss rainbow/gradient filaments, but I have been pretty much unable to find any in 2.85mm size. Has anyone else come across any, ideally availible in the UK.
  4. I have been conducting experiments with different TPU filaments and here is what I find. All but one are supposedly TPU95A: UM: works great! Matterhackers: Won't load properly initially and quits loading during printing Polymaker: same as Matterhackers NinjaTek Cheetah: works great! NinjaTek NinjaFlex (TPU 85A): same as Matterhackers You can 100% predict whether or not the filament will work based on the initial load. The filaments that fail will stop the initial load 2-3 inches away from the print head because of friction in the Bowden tube. The UM and Chee
  5. Hi everyone! Looking for some advice on ABS printing, I'm currently running into issues with bed adhesion and warping. I'll try to make this as concise as possible but include as much info as possible. Using a brand new UM2E+ with an enclosure made of corrugated plastic that sits at 95F-110F (depending on the printer settings) and 3D Universe ABS, which specifies 220-250C on the nozzle, 100-130C on the bed, and no cooling fan. I've tried printing nozzle temps from 230-250C, anything above 230C seems to give me a lot of oozing and over extrusion, mostly prese
  6. Currently, I am seeking for an aluminum filament for Ultimaker S5. I understand BASF offers metal filament but only in stainless 316L. https://ultimaker.com/materials/basf-ultrafuse-316l Does anyone sell aluminum filament for Ultimaker?
  7. I do not see this listed on your site... https://support.ultimaker.com/hc/en-us/articles/360012059859-The-Ultimaker-material-technical-and-safety-data-sheets Can you please provide this?
  8. I have used PVA dissolvable material in my S5 for awhile. However, with this spool that was fine initially, it now is starting to flow poorly, not stick as well to the glass, and is badically looking ragged instead of smooth. All the same settings. The only thing that helped a little bit was increasing the temp by 15C, but still is quite poor. So, I am wondering if this material degrades over time when the plastic wrapping is removed and exposed to air?
  9. I have a full reel of X STRAND 2.85mm filament - glass-fibre reinforced polyamide 6, GF30-PA6, which you can have if you cover the carriage (UK). Bought in October 2020. Open but stored with desiccant. Cost £70.85 plus VAT. I mistakenly thought I could print it on an Ultimaker 2+. Contact me on derek@blizzardsurvival.com or 07786-437962. Feel free to share or re-post this.
  10. I am trying to 3D print a diving canister used to store battery packs that power underwater torches, heating elements, etc. Traditionally these canisters are machined with a lathe using Delrin acetal homopolymer (Polyoxymethylene POM). They are often rated to 200 or even 300 meters (600-900 feet), which means 21 to 31 bars of atmospheric pressure (300-450 psi). This is how a Delrin machined canister would look like: And this is one of the 3D model to be used for 3D printing: I know POM-C is available from FrontierFila and Uayella as
  11. Does anybody have any tips on printing with Colorfabb NGEN Clear? I can not get it anywhere near transparent. My prints are always of a totally opaque frosted appearance.
  12. I ask because this is the first Ultimaker material that I have bought that didn't include a resealable bag in the box. Thanks for your assistance.
  13. Hi - First let me stipulate I am relatively new to 3D printing. I have done my fair share of printing larger and mechanical parts (as R&D is what we do) but I want to apologise in advance if my question is a trivial one and I am simply overlooking something obvious. I have modelled a part in PLA and it is time for printing the prototypes that will be used for field testings. These parts have large flat surfaces, so initially I though bed adhesion should not be a problem, even though I am aware larger flat surfaces can come with their own set of challenges.
  14. Hi All I hope this is the right place for this. We are having issues with Ultimaker filament spools we tend to get through about 25 spools a month, and use a material station with our S5. Every so often (we now have 6 of these) we get a spool that will not recognise, so there is no point adding to the material station as it will never take from it if a spool that did recognise runs out. Is there a way to "fix"/ replace just the tag as we are starting to build up spools of perfectly good materials that are just increased hassle to use.
  15. Seems like a semi common issue but I am having problems with the UM PVA support material printing correctly on a S5. I have tried a couple different spools with one brand new just ordered that is dry out of the bag which works much better in the tube and doesn't break before the print core which is good. But using the standard material and print core settings the material / extruder doesn't seems to stick or gets hung up on the nozzle and never prints correctly. Does anyone have any tips they could share as this seems to be a common issue from reviewing other posts. Sounds like the FormFut
  16. Hi all, I'm having some real trouble with an amazing statue print. Michealangelo's david. I must have tried 20 test prints but there is always something wrong with it. I'm using various standard PLA. I've got close a few times but there is always an issue with the left arm/elbow or hair detail with the support settings. Even at 0.15mm. 0.4mm nozzle. 55% overhang support etc. Settings are attached below! Can anyone suggest a better set of settings? Please help, Thanks
  17. Good day, my fellow 3D geeks! I am a new member of 3D printing world and I am yet to print my first 3D model ever. I am waiting for my Ultimaker S5 to be delivered soon. I was given a gift card by the shop that sold me the printer so I have a bit of cash to spend. What materials and accessories should I get? I am not looking to do anything fancy in the first say... 6 months as I want to get used to the printer and learn its particulars first. Is the filament dryer worth getting? I have a humidifier in my apartment, so the humidity level is always between 35-40%. That you all very much in
  18. https://imgur.com/cYihrQY Is there a setting in Cura that lets you print these lines consecutively and not split up when there is a hole in the body? The sheen is not uniform when its split up like this. If not can someone who is very smart create one? I heard Prusa has this feature coming out soon.
  19. Hello, I compared the data sheets of the following Ultimaker materials: - PLA - PLA Tough - ABS Based on the descriptions, here is the classification of these three materials from the least resistant to the most resistant: 1 - PLA 2 - PLA Tough 3 - ABS And here is the classification of these three materials according to the values indicated in the data sheets, from the least resistant to the most resistant: 1 - ABS 2 - PLA Tough 3 - PLA Can you check the information in your data sheets plea
  20. Good afternoon, Hello to everybody! I'm writting here because the last few days I've been having a lot of issues with breakaway clogging. I was printing a part that lasted 3 days and when it had printed pretty well for one and a half days the breakaway got clogged. I did the atomic clean up, everything seemed to work fine, but two hours latter the printcore got clogged again. I've tried many things, cleaning, changing parameters in cura, changing the spool to another location, ... but any of them worked. I finally changed the printcore to another
  21. Hello, I have been trying to trouble shoot this Z-axis issue for this part; and after long hours and much frustration I have determined that the Z-axis is not advancing for this particular model. I Ran into this issue once before but I solved it by rotating the part 180 degrees. In this particular instance the geometry does not permit rotating the part to test if this would solve the issue. I am printing with Ultimaker PP. Its a part that I designed in SolidWorks (I haven't had issues with any other parts I made). I used cura 4.8.0 to slice the part, and it doesnt give
  22. Hi, So I just tried to print with a brand new Ultimaker PC using default Cura 4.8 settings (Engineering 0.15) with an AA 0.4 head. Ok, I did modify two things: I enabled blob and disabled brim (since the print has a large bottom surface). I used a liquid paper glue for adhesion. I priinted with doors closed and with an extraction fan in the hood (not very powerful though). The issues are (see attached pics): - "hairs", some of them burned (I used this head for tough PLA before - can that be the reason?); there are even hairs in the fan! - relatively poor surface quality - p
  23. Hi, i’m new at 3D printing; this is my third print 🙈. i noticed some strange pits and extensions, while printing in fine 0,1mm with some adjustments to speed (max 35) acceleration (max 2000), print jerk (25) and outer before inner walls (these changes were made because of some suggestions in a YT movie, to print more precise) printer S3, tough pla and pva. And maybe its just normal, because of the circumstances (next to openings which are supported by pva)
  24. Is someone sucesfull and consistend printing PVA with the Ultimaker S5 Bundle? I got Problems every print I do with this. Now im using Brekaway whenever ist is possible, but sometimes I need PVA. (And of course I bought the Material station etc because of the "good" handling for PVA) Some times the PVA broke, and stook in the material station (see Picture), other times the PVA broke at the extruder and the printer says "extrusion problem". Other time the PVA was stook in the tube to the PrintCore. Are there solutions or experience with this ? Of co
