  1. I would have made the round smooth part flat (since that part doesn't do anything?) and made that the bottom.  The pegs will then print at 45 degrees upwards, and you would have a solid contact on the bottom and require no supports. It will be pretty!

     

    That is what confused me too. I understand the desire to match the visuals of the original part, but that went overboard in a royal fashion with the choice of color. The use of plastic also means that you will have to adjust. Sometimes you can do things that the original part could not, other times you will need to make parts a bit more beefy due to the original being made out of a stronger material.

  2. Hello Didier,

    I understand but for me it was just to show what is possible to create with high end scanning of objects.

    so far i have not seen much of these high resolution complicated scans where all the details are kept in the 3D file and came out the same way from a 3D printer.

    So i wanted to share here what is possible to print, not taken from the web but build it myself from the start.

    I dont want to share the files public but i hope its ok to show the result here :-)

    If you do not want to share the files, that is understandable. However, we would like to know more about the steps, process and end result. What did you use to scan and how did you do it? Did you need to do anything with the files before printing? How did the printing go and how were the results?

    As it stands, we have one picture from quite a distance. This community thrives on detail and others' experiences :)

  3. On facebook Ultimaker linked to a Dutch tv show where they showed a 3d printed violin.

    Now there have been others before, mainly electric ones, but this one looked quite printable :O

    Had a go at google and found the original site: http://www.hovalin.com/make/

    I must say, I am SO tempted to try to make this. Not sure what material yet though, carbon, woodfill, or just a PLA/nGen/XT(and which color)

     

    Do they also provide .the stl files for musical skill and talent?

  4. Aluminum extrusions plus brackets is awesome on paper, but a real PITA to get squared in real life. I would never ever do such a thing again. Took my prototype apart before I had even tightened the last bracket. It was obviously never going to work the way I wanted it to.

     

    I was thinking about sort of a hybrid solution, where aluminium or steel parts are aligned according to machined or laser cut parts. Think of something along the lines of plates that cover the different sides, with holes to mount the extrusions to. That way the lining up and squaring should be minimized. Do you feel that would help anything?

     

    Will be trying to find out if there's anybody around LDN or UK or EU willing to waterjet Trespa for me :)

     

    Do keep me posted. I would be interested in that too.

  5. For a while now, I have been thinking about doing a scratch build. I cannot really decide between doing an Ultimaker clone, a Trespa Ultimaker clone or building something out of aluminium trusses and parts. The latter seems to be a bit like the Ultimaker Black. Could you tell us something about the problems you face with this solution, such as squaring things up?

  6. Ultimaker has stopped selling directly

    Oh, wow. I totally missed this, but that is a rather big deal. From a business perspective, it is an understandable choice. Doing the footwork yourself eats up massive amounts of time. Leaving that to resellers means freeing up time and other resources for development and support. From the user perspective, however, it is probably not ideal.

    I hope Ultimaker makes sure not to make the same mistakes Makerbot made.

     

    Within the next few years, the market for desktop 3D printers will change extremely. Pro machines will become cheaper (don't forget e.g. HP to enter the business) and the 'cheap' products get better every day. The air will become thin for Ultimaker.

     

    Don't forget it is the community that develops a lot of innovations. The standard printer is pretty good, but if you want to make it truly excellent, you are generally best off implementing a couple of improvements the community developed for certain problems.

    What bearings do you use? Standard Ultimaker or something from another manufacturer too - and is that a budget solution or something of a more industrial quality?

  8. Hi, you don't have to log in to view the forum.

    And if you have auto-fill you can enter your email with just one or two letters.

    It is not about logging in to view the forums, it is about being nagged to death when you don't. Every time you do a quick check without logging in, the pop-up screen jumps in to spoil the fun. I cannot imagine guests being all too amused by it either. There is little use in asking someone the same question 15 times in as many minutes.

    Auto-fill also only works if you have visited before on the same computer and with the same browser. On my own computer I just keep everything logged in. On other computers I do want to check the forums, but do not want to leave my mail address for anyone to find that happens to type the first letter.

     

    When you have logged in once, and enable 'remember me' you also don't have to login again next time you visit except when you log in from a different computer. (it can only remember the login with a cookie).

     

    That works well at home. Not so much on other computers, especially those that have been configured to delete cookies after closing (common for shared computers). It does not mitigate being nagged repeatedly and relentlessly either. You can only ask someone to do something so often before it starts working against you and it not being about the question any more.

    Try browsing the forum with incognito mode turned on. You will quickly see what happens :)

  9. I click the sign up now button, and then there's a second tab in the popup: login instead.

    Workarround for now :)

     

    Thanks, that sort of works. I found a couple of other things that quickly annoy though:

    - Not being able to login with your user name. A mail address typically is much longer than your alias.

    - Having to type everything all over again is you mistype your password or user name. This issue and the previous one amplify each other.

    - Again, the blue nag screen. As soon as I tried to remember my password, I got this blue screen again whether I wanted to sign up. Dismissing it meant I had to start all over again. That screen is seriously hurting the quality of this forum, it is a perfect way of scaring new folks away. It even pops up when scrolling through a page.

  10. Two things are somewhat troublesome:

    - The blue overlay screen keeps popping up on every page after being idle a minute or so. This is slowly but surely causing irritation.

    - I cannot seem to find a way of logging in. I need to attempt to start a new topic before I am prompted to log in, but just logging in does not appear to be possible. Though I might be missing something :)

  11. With sufficient effort, it could be done on a UM2, but it would be greatly complicated by the fact that the UM2 does not have sockets for swapping out the stepper motor drivers.

     

    That always seemed illogical to me. Burnt out stepper drivers are not a rarity, though maybe the UM2 has other protections in place I do not know abouit.

     

  12. I've asked Colorfabb it XT could be recycled and the answer was "yes it is" without any other details.

     

    My suspicion was already aroused, but now I am sure something is going on there they would rather have no one noticing. The stuff is probably as hard to recycle as good old oil plastics, or maybe even worse.

    They are just too expertly avoiding having to give any answers :p
