5 do's and don'ts of 3D printing settings, part 2

Five more slicer do's and don'ts: mouse ears instead of a full brim, scarf seams to hide the Z-seam, light colors first on the first layer, Arachne for text, and variable layer height to hide layer lines.

5 more do's and don'ts

Part 2 of the series. Part 1 covered infill, filament profiles, wall speed, supports and calibration. This one covers the details that make prints look professional.

Don't Do
Use a full outer brim Use mouse ears (brim ears) on the corners for adhesion that's easy to remove
Let the Z-seam ruin your prints Turn on scarf seam to spread the seam across the wall so it almost disappears
Let a dark color bleed into your first layer Open plate settings and set the first-layer filament order so the light color prints first
Let small text disappear Set the wall generator to Arachne so thin strokes print solid
Leave visible layer lines on curved prints Use variable layer height to print curves with thinner layers

How each one helps

  • Mouse ears hold sharp corners down, which is where warping starts, without a brim around the whole part.
  • Scarf seam blends the start and end of each wall loop instead of leaving a visible zipper or line.
  • Light color first stops dark filament from showing through or smearing into light areas of the first layer in multicolor prints.
  • Arachne varies the line width to fit fine lettering. More fixes are in 3 ways to fix your text in 3D prints.
  • Variable layer height keeps flat areas fast while smoothing domes and curves.

FAQ

Where is scarf seam in Bambu Studio?
In the process settings under Quality → Seam. It's also available in OrcaSlicer.

Does variable layer height slow prints down?
Only on the curved areas that get thinner layers. Flat sections stay at your normal layer height.

5 Do's and Don'ts of 3D Printing Settings. Don't use the full outer brim, but do use the mouse ears for easy removal. Don't let the Z-seam ruin your prints, but do turn on Scarf Seam to hide it across the wall. Don't let the dark color spill on your first layer, but do click on Customize Plate and drag the light color first. Don't let your text disappear, but do use Wall Generator type Arachne. Don't leave layer lines on 3D prints, but do use variable layer height when possible.
