Designing for 3D printing

  • Dimension vertical holes 0.4mm bigger
  • Experiment with “Horizontal expansion” in Cura. Use negative values when the outer dimensions of parts are too big.
  • Clearance (guidance values. Need tuning for different machines, materials and temperatures).
    • 0.15mm: snug friction fit
    • 0.20mm: able to slide easily
  • Print slower (±30mm/s) for better accuracy. In Cura there's an 'engineering' print profile (only available for Ultimaker S5) that tunes parameters for best dimensional accuracy.
Tip Rest machining

When using 3D Adaptive to go down to a horizontal surface, tick the flat area detection box. Otherwise smaller mills in consecutive operations might need to remove material from the whole surface.

Bore

The pitch parameter in the bore feature should be set depending on the width of the bore. For example:

  • hole diameter: 6,5mm, pitch: 0,18mm
  • hole diameter: 3,5mm, pitch: 0,08mm

Small diameter bores need to feed down slower since they will be milled way too fast. Also check if ramp speed controls the feed here

Some sketch curves cannot be converted to profile edges

Weird work-around


The problem edges show up in red.


Zoom in on one of the edges.


Right-click on the edge, and select Display control frame


A brown dotted line shows the control points. Select one of these points and delete it.


In the lower left corner of the screen, right-click on the yellow sketch icon and select Review warning to check if it is solved or not.
