Question 1

What is the standard overhang angle threshold below which most FDM slicers automatically generate support structures?

Accepted Answer

45 degrees from vertical

Answer

Most FDM slicers default to generating supports for overhangs exceeding 45 degrees from vertical, as steeper angles typically cannot bridge without collapsing.

Question 2

What two factors does layer height in slicing software most directly affect?

Accepted Answer

Part resolution and total build time

Answer

Layer height controls the thickness of each deposited layer, directly determining the surface finish resolution and the total number of layers—and therefore the build time.

Question 3

In additive manufacturing build preparation software, what is 'nesting' used for?

Accepted Answer

Efficiently arranging multiple parts within the build volume to maximize utilization

Answer

Nesting is the process of efficiently arranging and orienting multiple parts within the available build volume to maximize machine utilization and minimize overall build time.

Question 4

What does the 'wall thickness' or 'shell count' setting in FDM slicing software define?

Accepted Answer

The number of perimeter passes forming the outer surface

Answer

The shell count setting determines how many concentric perimeter passes the printer makes around the part exterior, affecting surface strength, print time, and material use.

Question 5

Which step in the digital pre-print workflow involves checking a 3D model for errors such as non-manifold geometry or inverted normals?

Accepted Answer

File repair and validation

Answer

File repair and validation detects and fixes geometry errors like holes, non-manifold edges, or inverted normals that would cause slicing failures or poor print quality.
