    Raised Edges

    in UltiMaker 3D printers

    Posted

    Not sure if someone has said this but in different terminology.

    Normally you are squeezing out a round shape and flattening it out into a rectangle shape and sticking it onto a complete surface below.

    In this instance one side is flattened out and stuck down as usual while the outside (that doesn't have a surface underneath) doesn't get squished flat and comes out as a thicker circle which goes higher and lower than the rectangle half (shape of a keyhole on it's side). On top of this there is no adhesion from underneath to prevent the normal warping and lifting of the non stuck down side.

     

    Newbie in search of guidance.

    Hi Dan

    I'm not a big reader so I skipped a few paragraphs in the middle :)

    You probably wouldn't mess up the build of the UM1, it will probably print well or not at all and then you can get plenty of help here.

    UM2 however seems more reliable, has a heated bed so you can print in ABS. It also has better bed leveling and probably prints slightly more accurately.

    To get your money back and make a profit you probably need to design and print something that isn't mass produced already and/or is not possible to make by injection molding.

    3D printing is a real fun and addictive hobby though so just go for it anyway

     

    Turn off bed after layer # or height ?

    Um... I think this one is much better probably:

    This one works better with multiple objects printed one at a time (where Z goes back to zero again) and I think comes with more things you can tweak.

     

    Yep this is the one that I used and works.

    This is in my ABS profile which does the 1st layer Flow rate at 133%, Nozzle 260, Bed 130 (not accurate).

    Layers are 0.12mm

    From layers 2 to 4 these settings are changed

    It slows down slicing a bit so you wouldn't want to add many more than this if you can help it

    ABS delaminating

    in UltiMaker 3D printers

    Posted

    When printing in ABS I encounter the following error

     

    The ABS is delaminating,

    I have a heatbed set at 100 degree and I am printing the ABS at 230 degrees.

    Any tips would be very helpfull as I do want to make ABS my standard printing material. I have read something about Natural ABS but I'am not sure what that is.

    Thanks

     

    Hi Mikilu

    More usual settings are 110C Bed and 245-250 Nozzle
