vertical versus horizontal holes

[Knochi 0]

Hi,

 

today I had to deal with hole diameters again. This time the part has holes perpendicular to each other. So one kind of holes has to printed horizontal and one vertical (or both diagonal, haven't tried that).

 

The outcome is interesting and disappointing. To compensate for shrinked holes i added 0.4mm to the desired hole size. That works for the vertical printed holes but screw up the horizontal printed (they are printed in size).

Another thing is the bridging at the small holes down. Doesn't come out well.

And there is this funny ghosting at the horizontal printed holes.

 

Model:

MagnetMount.stl

 

dimensions in model:

big holes=6.4mm,

small holes=4.4mm

 

dimensions in print:

                   vertical   |    horizontal

big hole        6.0       |        6.4

smal hole     4.2       |        4.4

 

Setup:

• Ultimaker S5
• CURA 4.4.1
•  Ultimaker Tough PLA blackMagnetMount.stl  
• Default Settings "Engineering 0.1"
• Infill 10%
• no Supports
• no Adhesion

 

Would another material help? What can I do to compensate for hole shrinking just in vertical printing direction (apart from adding the extra 0.4mm to just one kind of holes in the stl)?

 

Thanks in advance
