parts? - Direct metal laser sintering (DMLS)
Which of the following parts would a smaller, more inexpensive AM machine be best suited to
produce? - Conceptual model
What additive manufacturing method involves sintering granulated material to create a part? -
Powder bed fusion (PBF)
How do STL files represent the complex, smooth surfaces of CAD model? STL files represent CAD
models as: - A series of interconnected triangles.
What AM material is available in filaments, liquids, and powders and used in material extrusion
and selective laser sintering (SLS)? – Polymer
What term refers to manufacturers using AM as an intermediary step during a traditional
manufacturing operation? - Secondary process

resistance? - Lattice structures
What type of AM layer construction method involves creating lines of material with a single-point
source? - 1D channel
What is one aspect of a final part that engineers or operators select when creating the CAD model?
- Resolution
What is one barrier to AM growth in the overall manufacturing market? - variable part tolerance
What manufacturing process involves stacking layers of material in order to create a finished part?
- Additive manufacturing

What computer file represents an AM part as layers and automatically generates the toolpaths for
an AM procedure? - G-code
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: - Create a 3D CAD model of the part.
, What is an advantage of additive manufacturing? Additive manufacturing: - Allows for more
freedom in part shape
What type of safety equipment can be used to help prevent operators from building up a slight
electrical charge, which could light a pyrophoric material on fire? - Antistatic mats
Which additive manufacturing method involves cutting a shape in a thin layer of material and then
fusing that with other layers? - Sheet lamination
What additive manufacturing post-processing operation smooths the surface finish of the part and
requires a dust mask and gloves? - Filing
Which of the following statements describes additive manufacturing? Additive manufacturing is
the process of: - Building parts through the stacking of successive layers of material.
Which of the following is one of the required categories on a safety data sheet? - Hazard
identification
What is one way operators can protect against the electrical hazards associated with additive
manufacturing? Operators can: - Ensure the machine is grounded.
What type of radiation hazard is caused by the light used to cure liquid photopolymers? -
Ultraviolet radiation
