Hi guys

I'm trying to print this on an ultimaker 2. Dimensions are 8x8x4mm, so it's really small. The lens circle is a gap of 0.5mm, and the little circular hole on the camera is also 0.5mm diameter.

https://www.icloud.com/photostream/#A35M7GFPa5Ej5;6EBD0F72-BBC9-4F3E-9938-9A11E9F96C7F

What happens when i print is that the lens circular gap, as well as the 0.5mm diameter hole gets filled in completely.

How can i improve this print? do i speed up the fan so that it cools faster once printed, so it does not "overflow" into the hole? or slow the print down? any other tips/suggestions? does layer resolution help here?

Many thanks in advance..

    I recommend tilting the object so that the icon is at the front instead of the top. This will most likely print better. As the details on the XZ and YZ plane are better then the XY plane.

    Look at the part in cura "layer view". Is it filling in the holes on purpose? If so uncheck "fix horrible type a' in cura.

    Please show a photo of your result. For example:

    the 0.5mm diameter hole gets filled in completely.

    May mean different things to you and me. For me completely means you can't even tell where it was supposed to be because the slicer put diagonal lines over it. Alternatively if it is just a bit small then make the hole larger in CAD by say .3 to .5mm to compensate for your result.

    but i think the molten plastic kinda "flowed" into it...

     

    More like "stretched". Melted PLA acts somewhat like a rubber band and it gets pulled along and into the middle.

    Try around 1mm diameter to get .5mm hole and maybe 10.5mm to get 10mm hole. In other words try adding .5mm to every hole diameter.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
