  1. Hello,

    I've done two testing prints, same object but different speed and layer heigth settings: 0.06mm and 40mm/s vs. 0.2 and 100mm/s.

    I observed that on certain areas, even the settings are different, the printer is moving the same (and i'm not talking about the first layer).

    Is it normal that the printer itself decide to use a certain speed on some areas?

    Which are the factors that affect this?

    I may post two videos regard that.

    Thanks,

    Stefan

     

  2. I can say i have some practical experience as i am an Architecture graduate (evan if i don't do that for a living), also some experience with 3d software. I also know that, like in manny areas, you get the most knowledge from live experience.

    What is was looking for is not a 600 pages book but something that would help me design the desired 3d pritable object without too manny compromises. The problem is that i don't have too much time to fool around, so i was trying to prepare evan before i get the printer (i'm looking for UM2), and the lead time is 8 - 10 weeks.

    There are a few modeling guidelives but i's sure there are a lot other tips and tricks: https://www.beeverycreative.com/en/beegallery/directrizes-de-modelacao

    Meanwhile i will try to search on internet and scan the whole UM Forum and maybe i will post here what i find usefull.

     

  3. Is there any guide for 3D printing?

    Starting with the printing technology, what is possible, what is not possible (overhang angle limit, bridges), how can you achieve shapes that usualy are not possible (e. g. by using removable parts to get larger bridges), and 3D printing specific proceed to get better results, print faster and consume less materials.

     

  4. Hello,

    I will add my questions here, as i'm also a newbie.

    I also intend to buy a 3D printer, i stopped for Ultimaker because of their high resolution.

    (It may not be fair to ask here, but are there similar competitors? Why should i chose Ultimaker in front of them?)

    My intention is to create sort of hardware box for some device prototype.

    My questions are:

    1. Is Cura just to prepare the print or works for modeling?

    2. How much i have to clean after the print so i can get a acceptable result? Are this (in pics) usual "errors" you get during the print?

    3. Are there specific shapes i should avoid? Can i create elastic parts that "Click"?

    4. What are the PLA properties? is it elastic, shock and heating resistance, how does it react to long exposure to sunlight, freezing or other outdoor conditions?

    5. Any other usual facts i should be aware while designing the shape?

    Thanks in advance,

    Stefan

    PS: Sorry, i'm not a native english speaker, please ask if anything is fuzzy.
