  1. Hallo Zusammen, Bei dem Ultimaker support habe ich nachgelesen, dass es möglich ist, PVA mit Hilfe der Druckplatte zu trocknen (How to dry Ultimaker PVA – Ultimaker Support) Es wird beschrieben, dass dazu die Druckplatte auf eine bestimmte Temperatur erwärmt werden soll. Allerdings habe ich bei dem UMS5 pro Bundle nicht die Möglichkeit gefunden nur die Druckplatte auf eine bestimmte Temperatur zu erwärmen. Im Idealfall würde ich zusätzlich gern noch den Lüfter der für die Zeit des Trocknungsprozesses laufen lassen.
  2. Ich wende mich mit einer Frage an dieses Forum, da ich - auch nach längerer Suche - leider keine Antwort im WWW gefunden habe. Es geht im Folgenden, um einen zwei Komponenten Druck mit PLA und PVA, bei dem (rein exemplarisch) der bekannte PVA_Würfel (siehe Abbildung "PVA_Bauteil") entstehen soll. Durch den hierbei notwendigen Einsatz von breitflächigem Support (siehe Abbildung "PVA_Endprodukt"), kommt es während des Druckes mehrfach dazu, dass die Schicht zunächst mit dem PVA-Material begonnen wird. Die diversen Positionierbewegungen verlaufen dabei jedoch über das - in dieser Schicht - noch nicht gedruckte Bauteil (siehe Abbildung "PVA_Bewegung"). Da die Distanz zwischen dem Ende und dem Start der neuen PVA-Bahn so gering ist, kommt es dazu, dass Fäden gezogen werden, welche durch Einschlüsse das Gesamtergebnis des fertigen Bauteils negativ beeinflussen. Dieses Problem tritt dann eben jede zweite Schicht auf, da ein Wechsel nach vollendung einer Schicht natürlich ineffizient ist. Jetzt war ich also auf der Suche nach einer Option im Sinne von "Bei jeder Schicht zuerst das Bauteil, dann den Support drucken" oder "Extruder x beginnt immer vor Extruder y". Bestimmt ist noch einiges anhand der Materialeinstellungen zu verbessern, aber es wäre eben viel einfacher, wenn er eben nicht die Bahnen des in dieser Schicht zu druckenden Bauteils fährt.
  3. Hi folks The build plate of my brand new Ultimaker S5 undergoes active leveling before each print. It results in either of my 2 extruders over or under extruding. Is there a way i can disable this active levelling process before each print, as i personally prefer manual leveling. The prints doesnt look that cool compared to the price i paid for this printer. Hope there is a solution to this.
  4. Salve ho un problema con la rimozione dei pezzi dal piano di stampa, utilizzo uno spruzzo di lacca per l'adesione ed ha sempre funzionato, ma ultimamente quanto stacco i pezzi mi ritrovo puntualmente scaglie di vetro attaccate alle stampe.... Materiali CPE+PVA piano precedentemente ricalibrato manualmente... Grazie a chi saprà aiutarmi CPE AA04 + PVA BB04 h0.3 v17 UMS5.curaprofile
  5. Hallo zusammen, ich habe einen UMS5 und habe bereits ein bisschen was gedruckt. Allerdings bin ich mit der Stützstruktur nicht so recht zufrieden. Das am Anfang mitgelieferte PVA von Ultimaker kann zwar rech easy gedruckt werden, allerdings ist es meistens als Stützmaterial eher experimentell und die Aufbewahrung von PVA ist etwas nervig. ich habe bereits einiges auch über das Breakaway gelesen, aber um ehrlich zu sein will ich für n Stützstrukturmaterial keine über 50€ pro 0,75kg Rolle bezahlen.... aktuell drucke ich die Stützstruktur aus dem gleichen Material, wie das Bauteil selbst, habe dann allerdings das Problem, dass es zumeist ne zu gute Verbindung mit dem direkten Bauteil eingeht. Was nehmt ihr so her, bzw. was habt ihr so für Erfahrungen gemacht? Eventuell hat auch jemand von euch nen Tipp für mich, wie ich bei gleichem Material besser damit umgehen kann. schöne Grüße Druckermanne
  6. Hallo, ich will derzeit ein Eletkronikgehäuse drucken. Beim slicen mit Cura kommen etwas komische Stützstrukturen. PVA Brösel liegen im ganzen Drucker verteilt und manche bleiben an der Düse hängen. Dies zerstört den ganzen Druck. Die Stützstrukturen werden einfach in die Luft gesetzt, ohne irgendeine Verbindung zum Bauteil. Habe auch keine Einstellmöglichkeit gefunden dies zu ändern. Bitte um Hilfe.

  7. Hallo allemaal, Graag jullie hulp. Als ik een PLA print maak met PVA support, krijg ik beschadigingen op mijn PLA. Zie bijgaande foto, waarbij ik heb geprint in mat zwart PLA. Het maakt niet uit welke kleur of merk PLA ik gebruik: elke keer komt dit terug. Ik heb al geprobeerd het op te lossen met de temperatuurinstellingen en support afstand, maar tot nu toe krijg ik het niet opgelost. Enig idee wat hiervoor de oplossing is? Ik lees het graag!
  8. We have been beginning our work creating American Made components, Its been a journey. We are just getting started. After PLA and ABS printing and looking for ways to get the best surfaces, I thought I would share some of it. https://imgur.com/z6X9wpk Matte Black looks great but the surface will require too much post-processing. Copper wire goes around the bobbin but the top surface obviously looks not great. After changing some settings and working with ABS, its maybe a bit soft or not resonant enough so we tried annealing it. Bad Idea! PLA anneals well but it is pretty strong from the get go. Black Tough PLA lead me to the Transparent PLA which won. imgur.com/a/YI3YhFg You can immediately tell by hearing the resonant properties what material is what. http://imgur.com/a/JUaB1Xz It has to have virtually no post processing, so we settled on 45 degree angle prints so the surface is all the same. Its worth noting that even after the S5 cleared the material out of the nozzle, it still printed the first part of the Transparent PLA with black ABS material, probably from the print head itself. http://imgur.com/a/jm960hy Annealing PLA causes some distortions that aren't acceptable with this application, so later today I am going to print a few completely walled off with PVA 100% support, 100% infill and toss it in the oven to see if it distorts. I hope not, because if it distorts in the process of creating the product, its going to be a problem.. I wound it up, got it ready to be used. Looks great for a first draft; http://imgur.com/a/NIS2Cim What do you think?
  9. Machine: UM2, mark 2 upgrade, olsson block I recently did the mark 2 upgrade and will use the second nozzle for dissolvable supports(PVA). I am worried that the PVA sitting in the nozzle will mess it up. Apparently, the ultimaker 3 BB core has a internal geometry allowing it to print PVA well. Is this really an issue and are there nozzles capable of printing PVA that will fit in my UM2(M6 threads, 2.85mm)?
  10. Hi! I'm experiencing tons of problems using the material station with PVA material. Basically the problems I have are 2: PVA Brokes always somewhere in the path form MS to Extruder Flow sensor Error during print The first case obviously is the worst case, since sometimes in order to restore the printer i have to disassemble all tubes and push with ABS [i.e.] filament through the material station and get rid of broken pieces. This appened a few times using third-party filaments, so i decided to switch to Ultimaker filament of course, but then had lot more problems and the filament brokes even more easily then the other. ( had problems and broke the filament also when loading without material station, it was really too much dry) Left also the material a couple of days inside the MS to let him "adapt" to the ambient and then re-tried but problems where the same. As a last try, in order to verify extruder problems, I had disabled MS and printed a standard S5. No issues with both materials. in my opinion, the path of the fliament to the extruder is just too complex and dry PVA is too brittle to move along that path without breaking out. Do you have any feedbacks on this? anyone other then me experienced this? I bought MS in order to use it just for keeping PVA in a good state so it is really a pity that it doesn't work, but i really want to make it work so any help from the community or frm Ultimaker will be really appreciated. kind regards, Diego from Medics
  11. I have a fairly new UM3E and the only issue I'm currently having is that printing PVA supports is not working well. I'm only using Ultimaker filament and I've only printed from the same reel of PVA on the BB core. After printing Benchy and a couple of other prints, the PVA printing from print core 2 - the BB 0.4 (extruder #2) that came with the printer, has stopped extruding material. The first time this happened I followed the printer cleaning directions from Ultimaker using Ultimaker cleaning filament. I removed a lot of black carbonized gunk and was able to get the PVA to extrude a little. On my last print I noticed that the PVA filament had broken near the extruder. After more cleaning and no PVA extruding from the BB core I decided to post here. I've been using the defaults in Cura, Cura is auto recognising the Ultimaker filament. I took a look at replacement BB cores but at EUR 165 maybe I need to just replace the brass nozzle(?). I expect something is out of adjustment because of the broken filament. In the mean time, I'm getting good print quality out of the AA core (extruder #1) without supports. What sort of performance should I expect with PVA and the BB core, what tweaks could I make to improve my experience with the PVA? Are there any other cleaning techniques beyond the hot/cold pull to clean/fix my BB 0.4 core and how do I clean the nozzle? Attaching photo of the current state of the core nozzle. The AA core (extruder #1) nozzle looks like shinny brass - not sure why so much PVA material is collecting on the BB nozzle but I'm knew to this and probably making a rookie mistake. Thanks. Larry
  12. hiya all. there are all sorts of solutions. I created a drum that went round the reel as a starter for ten. I have designed a case which I am yet to order the plexiglass for. however, I decided to try something different. A FOOD DEHYDRATOR. so I went for it, found one for £23,-. Initially I thought it would be a main section and had tiers inside it. however that wasn't the case. It is all made up from layers. So ok, I decided to keep 2 with their grated bottom and removed the rest of them. Idea is to contain 2 spools. I then designed a spool mount so they would sit nicely in the middle and allow to rotated. I then designed a tube holder to mount on the outside so that I can feed the filament without removing it from the Dehydrator. added a pneumatic fitting to hold the PTFE tube in place. and this is what I ended up with. there are two spools of PVA in there at the moment. and one feeding tube. (only because that's all I had) one of them has been playing up and low and behold, 1hr at 50deg and boom all was well. so for about £30,- I have a fully wooorking solution. I will upload the parts I designed. I am also going to make a frame to go around the feeeder so I can hold the feeding tube in place during retract. let me know what you think Rebekah Anderson
  13. Hallo, Voor het eerst gestart met printen met ondersteuning van PVA.. Settings in Cura aangepast (ext. 1 PLA en ext 2 PVA). hij start goed, maar al snel krijg ik de 1e foutmelding: Ultimaker-226d6a. En vervolgens stopt hij en geeft de melding: 'Een materiaalsoort lijkt leeg te zijn. Plaats nieuw materiaal om het printen te hervatten'. Beide spoelen zijn echter nog helemaal vol, happeren niet.. Als ik vervolgens op hervatten klik doet hij dit een minuut of 20 om dan opnieuw te stoppen en dezelfde melding te geven.. Iemand een idee wat dit betekend en hoe dit opgelost kan worden? Gr. Anne
  14. Does anyone have any ideas as to the causes of the visible layering in the picture? I'm using eSun PLA+ filament with the settings shown below and Ultimaker PVA (with built-in standard settings).
  15. Wir haben einen neuen Ultimaker S5, welcher mit PLA und PVA ausgerüstet ist. Bei der XY-Kalibrierung wird das X-Kalibrierungsmuster und das Y-Muster mit PLA gedruckt. Nachdem der Drucker auf PVA umgeschaltet hat fährt der Druckkopf alles ab wo gedruckt werden sollte aber es wird nichts gedruckt. Das PVA Material wird dann die ganze Zeit vom Feeder zurück gezogen und dann wieder nach vorne gestossen. Wenn ich allerdings ein Teil mit einer Stützstruktur drucke, dann funktionierts mit PVA. Hat jemand eine Idee was das Problem sein könnte?
  16. Hallo Ich habe schon ein paar Versuche gemacht mit einer Stützstruktur, leider druckt der Ultimaker S5 nicht sauber sondern schmiert das Natural PVA eher hin und es sieht auch aus als ob es zuviel Material ist. Es wird dann auch ins Teil eingearbeitet wo es gar nicht sein sollte. Ich verwende original Filamente, Standard Einstellungen des Druckers und Cura 4.6.0 Was mache ich falsch?
  17. Greetings All, I've had the UM PVA snap in the bowden tubes as the filament enters the coupler (the rectangular thing on the back of the material station inline with the bowden tube) a few times. I've been able to recover, but would rather not have to go through that process too often. I've seen a few posts about this, but not much by the way of fixes. In both my failures they occured in the morning after the printer had been off overnight - material station is left on. I am wondering what the working temperature of the PVA is? I know storage is between 0c and 30c. I am guessing that the temperature in the room is somewhere between 0c and 5c in the morning if everything has been turned off. Don't have thermometer, just going by the outside temperature. How brittle does PVA become as it gets cold? Are there other things that can effect the PVAs mechancial properties that would make it more likely to snap? Also, the snaps occured at 50cm and 53cm from the end of the filament as it was being sent from the material station. Maybe that's helpful to know. Thanks, Robbo
  18. Hi Forum, My UM S5 can no longer print with Print Core 2. First I tried to clean the nozzle, but it turned out that a spring prevented the Print Core from being placed correctly inside the Print Head. Please see attached photos. I tried to place the Print Core, using a tweezers to push up the spring, while inserting the Print Core. But still the Print Core cannot print. I also tried with a new Print Core, but still no printing. I guess that the new Print Core isn't clogged, so that cannot be the issue. Does anyone know about this spring? Is something broken, or will I be able to push the spring back in the correct position? Does the spring failure have any relation to the non-working Print Core? Any help is highly appreciated.

  19. I have to buy an Ultimaker s5 and I would like to print the supports with PVA, on the site I found information that I cannot understand, the information is this: BB 0.4, BB 0.8, are they extruders to be purchased separately or are they other objects? Are they present in the package?
  20. Printer: Ultimaker S5 Issue: After running the cleaning option I was able to unclog the AA 0.4 core in slot 1. But the BB 0.4 core in slot 2, which has PVA loaded, will not unload, and therefore cannot be removed, and also is preventing any printing. When we try to disable core 2 in Cura and just print with core 1, PLA via AA 0.4, it still says that core 2 is overheating. We might not be able to get this serviced for several days to a week, so we're looking for a way to at least get the filament out and the core out. Our hope is to then just use our two AA cores to print with no PVA. If we pull the tube and cut the filament, can we pull out the core without heating it and initiating a core change int he software? Can it be pulled 100% manually? Additionally, we have only used the BB 0.4 core twice, and both times it failed. So we have not yet had a single PVA-supported print since buying the printer 1 month ago. The nozzle tip on the BB 0.4 also appears charred, after 2 uses, both of which failed within 10-20 minutes of starting. So this core has barely been used. Any tips would be greatly appreciated. Thanks!
  21. My company purchased an Ultimaker S5 for a job and we have been printing parts consistently for a few months now with the same print profile. All of a sudden, prints are beginning to be super inconsistent and most commonly coming out like the picture below. It is very important to resolve this issue as soon as possible as the deadline for the project closes in and we are falling behind on print time. I have tried doing (tons) of hot and cold pulls on the print cores. I have also switched the print cores out with replacements and run into the same issue. We currently have a new set of print cores on order and I am hoping this will resolve the issue, but in the meantime, what are your guys thoughts on what causes issues like this? Using Tough PLA with AA 0.4 and PVA with BB 0.4. Infill on 20%, printing at 215*C, print speed is 100mm/s, layer height of 0.25 mm.
  22. Hi, we try to print a support with overhang which needs support. Unfortunately, Cura does not put support on the whole area but leaves an area with no support in the middle. I assume, that Cura wants to save support material and thinks, that the printer will use bridging. This works in 20% of the prints, in 80% not. The first layer which is placed on the support fails quite often. I attached some photos and some cura screenshots. Is there a possibility to improve the slicer in a way, that it does not leave areas with no support? Or can one improve bridging? We are using Ultimaker PLA material for print and Ultimaker PVA for support. Does this bridging fail because of bad adhesion of PLA on PVA? As already mentioned, I attached photos, screenshots of slicing and of the support settings (basic settings from Cura) Thanks in advance for your help and ideas :)
  23. Hi Guys & Gals. I have encountered an interesting "Phenomena" where Cura (4.4.1) almost intentionally leaves certain overhangs unsupported when printing the support material with core 2 (PVA). Printing with an UM3, AA 0.4 and BB 0.4 cores, PLA and PVA. I have played around extensively with the parameters and settings and haven't found any solution yet. For the attached illustrations- I have set everything to default/standard: Model: Here is the model and the specific area of interest for me with the standard settings visible. Slice Preview: Here the preview SEEMS fine with more than enough PVA support all-round (Yes, I can set the XY ofsets ect to print less PVA blah blah but that's not the point of interest here) Problem: Here you can see that it leaves a big chunk of support out where it really SHOULD be putting support...? (Note here that I kind off despise the "Gradual infill steps" setting but understand how it can be beneficial but i mostly set it to 0). I mostly hope that it is me missing something extremely obvious, but it gets interesting; When I SWAP the extruders.... It supports it correctly. Swapping printing Extruders: Note that I only instructed cura to use extruder 2 for the model and extruder 1 for the support: I have tried multiple permutations of settings to try and get the PVA in the same manner as the PLA (eg making gradual infill steps 0, grid as support structure, density same as infill density ect ect ect but I am always left with this mysterious gap when trying to support that overhang with PVA.. Even tried putting the PVA BB core in Slot 1, and PLA AA to Slot 2 but the slice will still result in the unforgiving black-hole of "NO-SUPPORTNESNES" So for now I'm left with a dead light-bulb floating over my head until I can figure it out. Anybody maybe know what the obvious solution is that I am missing?? Okay love you guys, Cheers!
  24. Hi there, Last week, I started working with a UMS5, after some former experience with a UMO/UM2E. The first models, I did in TPLA, supported by PVA. After dissolving the support, I sometimes have a very unconsistent and warped layer. The bottom of my model that faced the build plate (rounded corner in the left is warped as well) looks quite terrible: Unfortunately, I don't have the gcode files saved. The settings in Cura are like this (translation below): Translation: Generate support / Support extruder / Support interface extruder / Support roof extruder / Support floor extruder / Placement support: everywhere Setup: UMS5 with glass build plate with glue, TPLA/PVA, air manager. I've been looking into this problem, but I cannot find a solution. Anyone any ideas? T_D
  25. Hallo Zusammen, Ich habe zwei Teile mal zu lange im Wasser gelassen um das Stützmaterial weg zu waschen. Dabei haben die Schichten angefangen sich voneinander zu lösen. Ist das Normal oder ist da ein Fehler beim Drucker/Cura?
