Topic: Holes in surface

Hi folks,

after messing up my brand new Solidoodle 3 (see: soliforum.com/post/16463/#p16463) I had to recalibrate the whole device. As I am a complete newby in 3d printing this is kind of a challenge for me wink

I followed the instructions on the Solidoole wiki (Layer, Print Bred and Extruder calibraition, no flow rate calibration, yet) but the results are kind of a mixed bag. The worst thing is that the surfaces of the printed objects are not solid and there are holes in them. I have attached a picture that illustrates my results.

The printed object is part of the Dial Indicator for my Solidoodle. I tried to calibrate the the print bred with the paper method and I am quite confident it is not perfect as it is.

Regarding the settings I used pretty much the standard settings ( 200° Extruder, 95° Print Bed and .1mm slicer)

Thanks for suggestions,
Elias

Re: Holes in surface

I had this same problem. Do the flow rate calibration to make sure enough plastic is getting extruded and add a few more top solid layers.

Any particular reason you are printing that part @ 1mm other than just to see how it looks.

Re: Holes in surface

What infill ratio are you using? You might be running too hot for .1 mm layers, as the extruder is melting the layers already laid down. I've found I need a fan for solid layers (and an enclosure to ensure you are blowing already warm air). The fill ratio needs to be 50% or better to give enough support for those solid layers that get laid on top.

.3mm should be fine for this part though.
