CAMT Software & Digital Workflow Flashcards

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

Answer: 45 degrees from vertical

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

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

Answer: Part resolution and total build time

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.

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

Answer: Efficiently arranging multiple parts within the build volume to maximize utilization

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.

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

Answer: The number of perimeter passes forming the outer surface

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.

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

Answer: File repair and validation

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.

What is a 'raft' in the context of FDM slicing software?

Answer: A flat mesh base printed beneath the part to improve bed adhesion

A raft is a multi-layer horizontal mesh printed beneath the part that increases contact area with the build plate, improving adhesion and reducing warping especially for shrinkage-prone materials.
