  1. Hello, I'm relatively new to the 3D printing scene and have been going through the learning process of setting up my first printer and printing a few of my engineered parts/ etc. I'm very familiar with scripting and have found my issue in the gcode, and is not a firmware or mechanical problem on the printer. I'm using Cura 3.2.1 and been having an odd issue where, on particularly large prints, the absolute extrusion value will be defined to some extremely far off value and then proceed to eject all the filament, just for it to continue that section of code (for example an inner wall) - then finally return back to the extruder value where it should have been working off from. This results in huge retractions (which i had OFF in cura, retractions were disabled) and then also where the filament re-catches...extrudes meters of filament just to "catch up" resulting in a blob of where the event occurred. Sometimes the retractions and "catching up" happens in reverse order. See pictures: (Find "Z144" and scroll down in Gcode) Is this a bug? I've tried various settings and this happens on different models as well. I've tried with and without retractions as well as combing On/Off. Layer view looks normal and also inspected at the affected layer with playback: GcodeFail.gcode

    PLA vs Tough PLA

    I what circumstances would one use 'ordinary' PLA rather than Tough PLA, other than the larger range of colours available with 'ordinary' PLA?
  3. Coucou? Je viens vers vous pour vous exposer un problème survenu au fur et à mesure sur deux de mes machines, quasiment en même temps. Je ne sais pas si je suis devenu parano, mais j'ai remarqué depuis quelques temps que la tête d'impression dans son ensemble se met à avoir sérieusement chaud. Je remarque également depuis ce même lapse de temps que j'ai quelques irrégularités dans mon extrusion. Malgré tout, à l'affichage, la température semble stable. 2 hypothèses : - Ma buse touche la structure en métal de la tête d'impression : la chaleur se dissipe anormalement, la sonde m'indique toujours la bonne température mais il n'en est rien. La résistance de chauffe doit pousser plus fort que nécessaire pour atteindre la température ; l'irrégularité s'installe, et ça va pas du tout du tout du tout. - Il me manque cette graisse "cuivrée" entre le réceptacle en métal de l'isolant téflon et la pièce métallique carrée d'environ 3x3cm de la structure de la tête. Au fur et à mesure des démontages successifs, je n'en ai plus suffisamment à cet endroit. Je m'interroge et remet mon ignorance entre vos mains : peut-être cette graisse a-t-elle pour but justement d'isoler la buse qui transpire à 210°C du reste de la tête d'impression ? Si oui, quel en est donc la référence et où en trouver ? Un grand merci comme toujours. Antoine

    Low cost good filament

    ?Hi I have just started 3d printing with Ultimaker 2, I am so happy printing so many things, so easy to use and even pleasant to watch with such an elegant machine?. I'm now about to finish my first filament spool, have looked at the spool prices and the happy feeling is over?. Only kidding Still happy but just worry on choosing the right filament. I already made a big sacrifice on buying the printer itself I now need to look for affordable prices but at the same time have good quality. ?Could I please ask the community for any recommendations on good quality affordable filaments. The internet has so many companies I don't want to fall victim for cheap stuff. I live in manchester so ideally would like to buy from as near as possible to save on post. Thanks very much for your help

    Setting Cura for a Custom Delta

    Hello to all the community! I am new here :) I have a Colido D1315 PLA 3d printer (it's a Delta) and I have always used the related software for slicing and 3d printing. Overall the prints are OK, the 3d printer is well calibrated. But since I have some issues with the quality of the printing, and even trying different settings did not help, I decide to give a try with another Slicer and so I chose Ultimaker Cura... Now, Cura doesn't have automatic settings for my 3d printer... But I can add it as Custom. The 3d printer is a Delta, I had set the parameters related to volume and area, the filament diameter 1.75 and the nozzle (0.4) As Gcode Flavor I tried the Marlin and the Griffin ( but I don't know how much impact they can have) I tried to do a first print, with the Malrlin flavor, and the print did not come out well, I stopped it at midprint because the model was ruined... With the Griffin Gcode it went better, the object was printed but the quality was poor (lots of perimeters bubble) Any suggestions on the settings? Do I have to set some other things? It the Gcode Flavor so relevant to the quality of the 3d printed object? I'am attaching some screenshot of the custom 3d printer settings.
  6. Hello Cura Community! I am having a massive problem and I haven't been able to print for a long time. This problem is that I can't save to my SD card or (removeable device) without my Cura crashing... I have the Creality CR-10 as a printer, and my cura is the newest version (3.5.1)! What happens is that when I save to my remove able device my cura crashes... the weird thing is, is that it still saves it to my Sd card but when I put it in my printer, it won't heat up the printer or anything, it's like nothing is on the file... Anything will help!! I tried to be as thorough as I could!
  7. Bonjour à tous. J'aurai besoin de votre aide. Je n'arrive pas à comprendre je dois imprimé une demi-sphère un peu creuse avec ma UM2+ PLA, mais les supports intérieur, ne se dessine pas sur CURA 3.5.0. Il se créé seulement sur la 2ème couche pour ceux de l'extérieur ils sont bien intégrer sur la 1er couche ????? bizarre. Du coup le plastique n'adhère pas sur le plateau en verre çà fait des filament au milieu. J'ai essayé tout les type de support c'est pareil.

    Please HELP Me. CR10

    I im very frustrated. I have a cr10s when ever i save the g code on the sd card start print it heats up starts the first layer , then the print head stops about the second layer. ive benn using curas 3.4.1 and the ones after it [the newer ones] i even tried slic3r but same thing.So i tried one of the old g codes i had saved on my sd card that ive printed before and i printed it again worked perfecty.Can anyone please help me im so frustrated.

  10. We just purchased our S5 and are looking to model some of our products with some various materials. Specifically, we want to print the closest representation to the plastics we will be manufacturing through plastic extrusion and injection molding. From our understanding, settings within Cura can alter the material properties of the plastics that are printed. Hoping someone knows of any studies/papers/books that have information relating print speed, temperature, nozzle size, etc. to the material properties of the plastics.

    Change the Standby Temperature

    Hey guys, i still have a problem. I have a own 3dprinter ( no ultimaker ). I have already written the definitions and the other resources. When i print with one extruder everything is perfekt BUT it still have two extruder and if i start a print with two extruder it doesnt do what it should do! Because the standby temperature is 175 and i cant change it and it doesnt have enought time to heat up the nozzle while printing so i want that it is always on 200 degree i looked for a solution but nothing does this what i want. I also tested to write this in the definition: "default_material_print_temperature": { "value": "200" }, "material_print_temperature_layer_0": { "value": "material_print_temperature + 5}, "material_standby_temperature": { "value": "200" }, I hope everyone understand this, what i have written because my english is not the best Thanks for your help best regards
  12. Ahoj Omlouvám se předem, moje angličtina není dobrá. Mám problémy s tiskem, vrstvy v programu cura jsou špatně vykresleny a nevím, jak tento problém řešit. Můžeš mi prosím pomoct?
  13. How can the very latest, cutting-edge design software combine with a 5,000 year old manufacturing technique to deliver outstanding weight reduction opportunities? Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts upon the energy usage of the product during it’s service life. Lighter products mean less fuel to move them around, which can make our fossil fuel reserves go further, or make more efficient use of the renewable energies that we’re now beginning to adopt. Generative Design (GD) is the very latest design software released by Autodesk and is now included in Fusion 360, which is at the heart of their "Future of Making Things" strategy for Design and Manufacturing. It changes the way we design things and can deliver very efficient designs that deliver structural performance with optimised use of material. The aerospace industry is expected to be one of the early adopters of this technology because in that industry the cost and environmental savings from improved fuel efficiency carry the greatest rewards. Also, I see interest from the automotive industry for the same fuel efficiency reasons, but in the long term the drive for lighter weight parts could benefit many industries, even those outside of transportation. Another example of the benefits of lighter weight alongside reduced material usage is that shipping costs for parts reduce as their weight reduces, which can therefore also deliver cost efficiencies. GD is targeted initially at metal parts where the biggest opportunity for light-weighting exists. The complex forms it generates though often means that parts conceived in this way cannot be made with conventional manufacturing routes. They therefore need to use Additive Manufacturing (AM) techniques to produce them. The route of using high energy, laser-based AM to do this comes with associated high costs because of the specialised set-up knowledge required together with expensive processing, and post processing, to deliver a quality-assured part. This project explores the possibility of a more cost-effective route to a metal GD part which, even though at this stage may be just used for a small quantity of evaluation prototypes, can act as an enabler for understanding the potential that GD has to offer. This is the baseline design for this project. It is an aluminium bracket design similar to those used in aerospace applications to mount control surfaces, and in this form has not been optimised for weight. This design would weigh 383 grams in the intended material, aluminium A356. After processing this through Generative Design in Fusion 360 it’s time to review and evaluate the many alternative design options presented and decide upon the design that is considered the most appropriate taking into the other factors that have an influence on design selection such as manufacturability, aesthetics etc. This was the design option chosen for this part and Fusion 360 was used to create the final version of the model. The bio-mimicry that’s evident in most of the designs created by GD is interesting to see, in this case the design of the part can be seen as essentially a swept I-beam (which engineers, especially those in construction, are taught is a strong section), but with tendon-like attachments back to the mounting points to carry the tensile loading that’s created by the applied loading conditions What GD does is to turn the standard design workflow that we’re familiar with on it’s head. Traditionally we design a part and then stress test it virtually to determine if it fulfils the required structural performance. Any failures seen during this process require an iterative loop back to the design to correct them. With GD the stress analysis is a core part of the design synthesis, and happens as the part design iterates, which means that the output at the end should meet the requirements of the intended loading requirements. The software is searching for an optimal solution where the stress is ideally evenly distributed across the part as can be seen above. To prove that everything is good with the finalised design this part has then been virtually tested again in Fusion 360 to confirm that the original loading requirements are still met So we've created our lightweight part design, and maybe now we need to produce that in aluminium A356 to do some physical testing, but don’t want the expense of using a metal AM process. What follows is a way of achieving this where FDM 3D printing can play a role as an “enabler” to help create the final parts in conjunction with a very old (if not ancient) manufacturing technique called investment casting. This technique is 5,000 years old according to Wikipedia. The company involved with casting this project is Sylatech who have been using Ultimaker 3D printers as part of their process for investment casting of prototype parts Sylatech took the .stl file of this model and used it to create a 3D print of the part on an Ultimaker 3 in PLA. This PLA part was then used as the pattern in the investment casting process where it is submerged in plaster under vacuum conditions to ensure that all air is excluded from the mould and creates an accurate reproduction of the surfaces of the part. The picture below shows a display box which demonstrates the set up of the 3D printed parts partially encased in plaster. Once the plaster has hardened the casting box is put into a furnace at very high temperature in order to burn out the PLA, leaving behind a cavity into which molten aluminium can be cast. After solidification of the metal, and cooling of the mould, the plaster is broken away from the parts, and then they can be quickly and easily removed from the material feed gate resulting in these aluminium A356 versions of the PLA original. The final part weighs 122 grams which is a weight saving of 68% over the original baseline part, which shows the potential that GD has to make significant reductions in weight and material usage. Using this method we now we have an excellent quality physical part made very quickly in the final intended material in order to commence some physical testing.This is a different route to get to that physical test part in metal at a fraction of the cost of having it metal additively manufactured. It also shows how a brand new, cutting edge piece of software that only became available in May 2018 can combine with FDM 3D printing (which many people still see as a new technology even though it’s been around for over 20 years) and a 5,000 year old manufacturing technique to deliver potentially huge benefits in weight and material usage. Using the investment casting route in this case study is why I chose the title for this article, and shows that we can effectively go “Back To (Deliver) The Future”. Do you see the need for lighter weight parts in what you do, and can you see the potential benefits of using Generative Design and this method of producing metal parts? I'd welcome comments, suggestions, and discussion about any aspects of the above article, the next steps that I'm looking at are how this process could scale up to batch production of the parts using 3D printing techniques that could support low volume production quantities

    Feeder problems

    The feeder works fine when changing material or inserting material but when you try to print you can see it and hear it moving but no material comes out. Clogged nozzle was discarded using the atomic method. Thanks in advanced.

    Alimentador

    El alimentador funciona tanto para extraer el material o filamento como para entrar el material nuevo. Sin embargo, a la hora de imprimir se escucha y se ve movimiento pero no sale material. Descartado que la boquilla esté tapada porque le apliqué el "método atómico" sin problema.
  16. Hi, I'm looking for some pointers as what to check/adjust to get this issue resolved on my prints. These prints are done in PLA, but aren't material specific. Cura versions: this happens with 3.5.0 and the previous 3.4.1. I don't think it's Cura version specific, I've had this issue for a while. This is printed at the default 'fine' setting of 0.1mm and a modified fine setting where initial layer height was decreased and print speed reduced to 35mm/s When I print, the bottom/100% infill layers seem to be dimensionally smaller than the layers higher up which are printed with infill. I even aborted a print, as you can see in the pictures where it shows the dimensional wideness changes at the infill printed layers. Any thoughts or ideas of things I could change to fix this issue? Picture 1 through 4 some examples where the first layers are smaller than the subsequent ones. Picture 5 through 7 you can see it starts when printing infills. Upload of pictures will be after posting as I need to do that from my phone. Cheers, Richard
  17. Hi everyone ? I have a problem when printing with two colors (PLA). The first layer in both color, no matter what layer they are on, are moved about 1-2 mm in Y direction. I have the newest firmware and done the xy calibration. The build plate is not loose and I use the newest Cura. Using 0.4 nozzle on both, and have tried 0.25 as well. The problem is only on two colors. I tried using raft, it does not solve the problem but it helps because the movement is done on the raft, but raft is only one color so the other color will have the wrong moving as well. The modell looks fine in Cura. Any suggestions? Using Ultimaker Extended 3

    Help with my prints!

    I got my Creality Ender 3 about a month or two ago and I've been having this problem. I've been printing for a while and my prints have missing lines in them every few layers. I have tried changing extrusion but that doesn't seem to work. Maybe temperature? I have no idea, please help. =\
  19. Hallo liebe Ultimaker Community. Mein Ultimaker2+ scheint irgendwie einen Bug zu haben. Die letzten Layer eines Print, druckt er "in der Luft" D.h. er legt filament NEBEN die eigentliche Geometrie. In der Slicing Software wird der Prozess korrekt dargestellt, zB die Pfade sind alle so, wie sie sein sollen. Das Problem liegt also scheinbar beim Drucker selbst. Hat jemand ähnliches erlebt, oder gar einen Work-around für das Problem? Beste Grüße und vielen Dank im voraus! Jan

    Supports messing up Model

    For some reason, when I print supports on any models, the layer that is in contact with the supports does not print well. In other words, it is not smooth and the print is of very bad quality, and sometimes the supports are hard to remove. It seems as if either the supports fuses into the model, or the layer does not cools properly. It only happens when I print supports, otherwise, when there are no supports touching the model, it prints just fine. Any help on what I'm doing wrong? I am using a Creality 10s with Cura 3.5 My settings are set as: Layer Height - .06mm (Extra fine) Top/Bottom Thickness - .6mm Wall thickness - .8mm Printing temperature - 200 degrees Plate temp. - 60 degrees Retraction enabled Retraction distance - 5mm Retraction speed - 40 mm/s Support pattern - ZigZag Support density - 10-15% Support Z distance - .265mm Support X/Y distance - .7mm

    verschobene layer beim drucken

    Guten Tag, Ich habe folgendes Problem: während des Druckens mit meinem 3D-Druckers verschiebt sich manchmal ein Layer nach links (innen). Am Anfang Druckte der Drucker problemlos nach einiger zeit entstand das genannte Problem. Ich hatte das Problem in der Vergangenheit schon einpaar mal, dies war aber nicht so exzessiv so das dies ein kein Problem darstellte. Da im diesem Fall aber übermäßig viel daneben "ging" habe ich mich mal an dieses Forum gewandt. Ich bedanke mich bei Ihnen für eine Antwort schon einmal im im Voraus. ?

    UM3 druckt nicht zweifarbig

    Hallo in unserer Bibliothek haben wir nun einen Ultimaker 3, den wir mit der Software Cura nutzen. Das normale Drucken ist kein Problem. Nur wenn wir zwei Fraben wir PLA blau und PLa weiß zusammen benutzen wollen klappt es nicht. Habe auch schon alle Anweisungen wie man das auf Cura einstellen muss gemacht siehe Internet Link https://ultimaker.com/en/blog/34012-get-started-with-cura-printing-with-two-colors Also für so ein Verkehrshütchen zuerst die Datei für die Ringe und dann die Datei mit dem Hütchen geöffnet, denn PLA geändert in White PLA und blue PLA, da diese Farben auf dem 3D Drucker sind. Dann wollte ich die Datei an den Drucker schicken, aber das ging nicht autmoatisch, sondern wie auf den angehangenen Screenshots, muss man das auswählen und genau da steht dann dass es nciht empfolen ist so zu drucken. Wenn ich das angeklickt habe, fängt er an zu drucken aber nach einer Schicht ist es dann auch vorbei, er druck dann in die Luft. Wäre cool wenn jmd schonmal auch Probleme damit hat, mir sagen kann was ich falsch gemacht habe oder wie man es richtig macht, damit der UM3 zweifarbig druckt ? LG Judith ?
  23. Hi All, I'm having great difficulty utilising my UM3 to get good quality parts using the standard profiles / printcores. I'm using Filamentive PLA filament and after limited success using the AA0.8mm printcore together with the default Cura PLA parameters, I invested in 3D Solex print cores to see if I can get better results but unfortunately I did not. I'm sure it's due to my lack of experience and nothing to do with the hardware. Therefore I'm here trying to bring my issue to your experienced eyes and hopefully your advice will make my UM3 usable. I tried 2 nozzle sizes with 3D solex, 0.8mm and 0.6mm and the results are shown on the attached images. I compared the 0.6mm results to the same exact part printed on a Prusa MK3 (using a 0.4mm nozzle thoguh) and I could not even come close to that level of quality with my current ultimaker profile settings. I took my UM3 to the UK service provider, thinking maybe i have mechanical issues and they admired how well looked after my machine was and confirmed there were no issues with it at all. If you can guide me through a trouble shooting process I would be very greatful. I know the UM3 is a very capable machine and it's a real shame to not be able to use it. Many thanks for your advice in advance.
  24. Hello everyone. Can you help me with my problem? I made an impression of 2 pieces and I could see that the internal sides of these pieces have many damages, on the contrary, their external sides do not have faults. What is the reason for this? Thanks in advance!

    Shiny Nike Air Max 90 Mini

    ....as the title suggests, but perhaps a bit too shiny! will age it later, if at all, but most likely will, nothing stays shiny for long with me these days....lol. Had fun with the photos....took way too many as usual.
