What step in the basic AM procedure must engineers or operators complete before creating an STL file and G-code file? Engineers or operators must first:

A. Select orientation and place supports
B. Set layer thickness on the machine interface
C. Create a 3D CAD model of the part
D. Load plastic filaments into the AM machine



Answer :

Final answer:

Engineers must create a 3D CAD model before generating STL and G-code files for additive manufacturing.


Explanation:

The step that engineers or operators must complete before creating an STL file and G-code file is to create a 3D CAD model of the part. This step involves designing a digital representation of the part that will guide the additive manufacturing process.
