Basic Tuning of print profiles

There are a few settings that have a significant impact on the parts you're printing. This is a brief intro to some of them, and by no means a comprehensive guide.

In general, more is stronger but also slower.

Perimeters (Vertical shells)

Perimeters define the wall thickness of a part on the vertical shell. The perimeter count x extrusion width is the wall thickness. The more walls, the stronger the part will be across the vertical shell;

We do not recommend going Over 8 walls on parts; in most cases, stress is transmitted across the surface of a geometry, and increasing wall count has diminishing returns; if maximum strength and stiffness is desired, increasing infill to 100% will result in better part quality.

Floors and Ceilings (Horizontal shells)

Floors and Ceilings define the wall thickness of a part on the horizontal shell. The Floors and Ceilings x extrusion height is the horizontal shell thickness. The more floors and ceilings, the stronger the part will be across the horizontal shell; this table below gives some general guidelines (for a 0.4mm nozzle)

Infill

Infill Percentage also greatly impacts part strength and print time in particular. We generally recommend infill ranges between 10 and 40%; less than 10%, and it can affect the integrity of top surfaces much more than the 40% becomes diminishing returns.

In the case of maximum strength and rigidity, or when trying to match FEA behavior of the part, we recommend 100% infill.

Tying Perimeters, Floors, Ceilings, and Infill Together

We tend to increase and decrease these settings together; below is a table with our guidelines.
