  1. Oop. I used one post to ban the user and remove that one, however I assumed the others (made by a banned user) would automatically become invisible. I should've checked, because obviously this is worse content than your average spam design. :S Thanks again for noticing...
  2. Hi all, These Liberator designs have been removed. They had slipped through the cracks. Thanks for reporting them here. Even though this eventually reaches us, it might not be the quickest way, we have created a private Telegram channel to directly remove spam posts. The channels gives a quick preview of each new post and has direct buttons to "Spam it" or take a closer look. The buttons in the channel will then directly update to reflect that it's been spammed and you can undo this. If anyone wants to help combat spam and designs like this, we would sure welcome this. Of course we would like to explain it a bit before we do this. E.g. a person can mute the channel and we can discuss in this channel to ensure someone is "on duty" but not everyone in this is distracted with each new post (I would argue: in today's day and age, attention is one of the most scarce resources). To reach me, you can e-mail me at ym - at - erikdebruijn.nl. If you're already on Telegram you can use @ErikDB there. Of course, don't feel any obligation to volunteer for this, but know that it is appreciated and probably saves time to catch spammers and "problematic" designs/posts.
  3. I agree. On the other hand it would reassure a lot of people more if Ultimaker would be able to organize a patent sharing pact with the other good guys in the industry .... IIRC there are a few others 3D printing companies with us who have joined the OIN. Aleph Objects, UltiMachine, Type A (?).
  4. Unfortunately this is already a reality. Ignoring the matter and not making a statement is not a sustainable practice. While these are not easy choices to make, we appreciate your understanding. We want to make a much greater impact tomorrow than we do today. Your support helps make this happen.
  5. I designed and printed lots of things that were practical. Door stops, holders for baby monitors, window drapes, etc. etc. Most useful: And e-Nable hand for a 6 year old girl in the neighbourhood. Apart from that, curtain holders: And for the sake of recursion, it's fun to know that Ultimakers have been made with the help of printed parts, even from the earliest beginnigs: A label dispenser that has helped bootstrap the company (and keeping the dull task of making kits a bit more fun: Another one of these tiny prints saved me and my girlfriend many many hours of work: https://www.youmagine.com/designs/wire-twisting-tool (see the video and you'll see why doing it by hand would have sucked). And a few sets of RepRap parts for RepRap Darwins and a Huxley. A part that would otherwise be 30 euros+ but now cost less than 2 euros and a bit if fun designing it: EV plug holder (on YouMagine):
  6. Great talk! I can see the Ian passion is no less to last time we saw each other! Good thing you embedded this here, so many more people could now watch this than were in the room. I think you make a lot of good points about the importance of a community to a company. Thanks for sharing your experiences from Pixpast and Ultimaker. Only thing that you didn't mention is that it's really motivating for the people in your company that the people in the community aren't just order ID's but actual people you can interact with. It's not just the other way around. I also appreciate how you remind us to not repeat our mistakes. We certainly need to. But don't think we aren't learning. Anyone has to be able to make mistakes to learn, otherwise you stand still. And standing still means becoming irrelevant. Learning from other people's mistakes is the only thing that works even better. Also, I really like how you made the drawings. I started appreciating good drawing skills now that my little daughter is born, but I still have to do it more to become better at it. In that sense it's not different than 3D "drawing". Practice makes perfect! Take care!
  7. Hi @xeno! Thanks for reporting this. We've updated our filters to be more strict and include a few more terms. This "episode" spam will now also get unpublished automatically and the accounts that made them get blocked.
  8. Thanks for posting this separately. I think the importance of a good search engine cannot be overstated. From what I gather is that: some context information is lost when changing page through pagination. Results aren't being ranked according to relevance. Is that correct? For YouMagine we've developed our own ranked search that weights the title higher than the abstact, higher than the description, etc. Tags are between the title and abstract. We might be able to use a similar technique here (and possibly the same search engine). Relevance is quite a subjective thing. I guess you would want to factor in several things and place weights on them. E.g. Occurence of keywords in title keywords in original post inverse of the age of the topic keywords in replies @peetersm (or anyone else for that matter), anything that would still be missing that will determine relevance?
  9. I have THF. Nasty stuff you need to be careful with, but I'd like to see what it does with PETG...
  10. Version 1.0


    I printed this hand for a girl in our neighbourhood. She's as cute a 6 year old as you can find. She has one hand with, and the other without fingers. We printed here a "new" hand that she can now show off to people. Immediately she could pick up and hold things. Her range of motion was still quite limited. When the physician that was treating her changed the Velcro straps, she could really use it much better. You can go to https://e-Nable.YouMagine.com to generate customised files for this design. Also, sign up at http://enablingthefuture.org to help a hand!
  11. Ik had om de ronde pot van binnen onregelmatig te maken een lang legoblokje van 1 breed vastgemaakt met hot glue. Simpel maar doeltreffend. Maar als je al weet dat je wilt kunnen polijsten kan je natuurlijk ook in een duurzame opstelling investeren. Ik wilde het voor mezelf bevestigen voordat ik zoiets kocht. Conclusie: het werkt.
  12. You need to use a version of your username that shows up in the address bar when you go to your YouMagine profile. For example, if my screen name on YouMagine is "Erik de Bruijn" it would show /users/erik-de-bruijn in the address bar. Take the part "erik-de-bruijn" and put that into your signature (obviously using your own username instead).
  13. Ik heb zelf een tumbler gemaakt van Lego NXT, prima om even mee te experimenteren. Er draait een Heinz tomatenpuree pot rond op 3 wieltjes. 1 is aangedreven en de andere twee zijn 'ilders'. Inmiddels hebben we een officiële tumbler op het (Ultimaker) kantoor, aangezien de methode "bewezen" is. En de Lego opstelling zal waarschijnlijk voortijdig slijtage oplopen, wat ik weer zonde vind. Polijstmedium bij mooie resultaten is schroeven en het doffe resultaat was met "officieel" polijstmiddel (keramisch). Mijn theorie is dat je juist de zachtere kunststof er een beetje vanaf wilt abraderen terwijl je het metaal overhoudt (dit is wat slijtvaster, dus dat blijft dan over).
  14. Als je met polijsten iets anders dan metaal gebruikt heb je meestal een heel doffe print: Brasso maakt het ook mooier doordat je een groene gloed (oxidatie) krijgt van het koper: Met een metalen polijstmedium (bijvoorbeeld schroeven) krijg je een residu op het voorwerp dat ook echt een metalen finish heeft. Links is onbewerkt, rechts heeft een nachtje in de trommelaar gezeten: Rechts zie je ook nog een copperfill printje:
  15. It's hardened glass and very straight and with tight thickness constraints. Otherwise, when you level it it the gap will still vary (between the nozzle and platform). Non-hardened glass will often break when it's heated up unevenly. A little expansion on one side that doesn't happen on the other will cause so much stress that it cracks. We've seen this with regular glass but not with the current glass plate.
  16. PLA and flex PLA have a similar glass transition point (or Tg, related to the melting behavior) and similar melting behavior. I would be surprised if there's not adhesion at all, however I haven't tried this. I'm currently printing the flex stuff. I could give it a try. Glueing PLA isn't too hard. I heard people are having decent results with super glue, but in your case You'll want a glue that can flex a little. PVC pipe glue usually has a bit of THF in it and is a filling glue. THF will dissolve the PLA a bit. I've used it to glue PLA and also to fill little gaps for vases and such, since you can seal an object with it.
  17. Yep, as Daid says. Especially revision 2 dates back a long time (Nov. 2011). The history of the wiki is useful here. As well as I could I tried to explain exactly what was in which batch. I never got around to really making a changelog except for software and firmware (because that was my thing mostly back then). http://wiki.ultimaker.com/index.php?title=Category:Part_of_Batch_03&action=history
  18. Hi Chopmeister, The popup problem is solved now. It had to do with a weird mix of a hosting performance measurement tool combined with a powerful but now framework suitably (and coincidentally) called Polymer.js. I would like to know a bit more about the WebGL problems you're getting... We definitely don't want that! :shock: Can you be a bit more specific. I think that a screenshot would be helpful in telling us exactly which error. Also tell us when it's triggered, if possible.
  19. @JonnyBischof: do you have a link to this specific design? Obviously a 82 MB file is challenging to display like this, but we can at least increase the transfer speed by a factor of 20 to 30 by sending the mesh compressed and decompressing client-side. We may have to limit the amount of triangles we display to get better performance.
  20. Thanks for all the feedback! Those who have given us feedback a while ago may have already seen many of their feedback implemented, so YouMagine is improving all the time! More social features like peetersm mentions are indeed desirable. Also we will work on as many bugs and features you're mentioning... but be patient... there's a limit to how much we can process at a time. One of the bigger things we've worked a lot on the first featured that is all about collaboration! You can now contribute pictures to a design that is made by someone else. The pictures will show up under "Printed by". You can also discuss the print result. The original designer can also decide to give your picture a more prominent place at the design page. It will then become part of the carousel (viewer). Also, it's now much easier to migrate/copy content from other sites. You can drag and drop the images right from Thingiverse over to YouMagine. Make sure to maximize the view on the Thingiverse so you're copying the high-quality version instead of downsized preview images. Also, you can provide design files by URL. So right click on the file on Thingiverse, click "Copy URL to clipboard" and paste it in the YouMagine window to directly add that file to your design. Also, we're working on a cool 3D viewer... so stay tuned for info when we launch an updated version of YouMagine! Again, thanks for all the feedback!
  21. Jet3D, welcome! I look forward to seeing what you'll make next! Glad you found your way into the Ultimaker community!
  22. Hi everybody who's waiting... You've already found your way onto the forums, so that's really great. If knowing that people are working over-time at Ultimaker to get you the UM2 isn't enough... and if you want to get the best start you can have, it makes sense to already download http://software.ultimaker.com/, look at our beautiful https://www.ultimaker.com/spree/uploads/31/original/um2-manual.pdf (it will also be in included in the box) and perhaps have a look at things to print or design on https://www.youmagine.com... Nothing is cooler than printing something you designed yourself, even if it is something really simple (my humble opinion). Thanks a lot for your patience!!
  23. Check out this Google+ post about lots of improvements to YouMagine! Front page search: More intuitive tagging: A "Surprise me" button! Multi-line comments: No more double e-mails when placing a comment. And an awesome automatically resizing top menu bar! (check it out online!)
