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.

Create a physical prototype.

Perform a stress analysis.

Conduct a market survey.

Answer explanation

Before creating an STL file and G-code, engineers or operators must first create a 3D CAD model of the part. This model serves as the digital blueprint for the additive manufacturing process.

What solid modeling tool do engineers use to create 3D part models for AM?

Computer-aided design (CAD)

Finite element analysis (FEA)

Rapid prototyping (RP)

Material requirement planning (MRP)

Answer explanation

Engineers use Computer-aided design (CAD) tools to create detailed 3D part models for additive manufacturing (AM). CAD software allows for precise modeling and design, essential for successful AM processes.

What removable AM components fortify an AM part as it is built?

Support structure

Base plate

Cooling fins

Heat sink

Answer explanation

The support structure is crucial in additive manufacturing (AM) as it provides stability during the build process. It is removable after printing, allowing the final part to maintain its intended shape and integrity.

What term refers to manufacturers using AM as an intermediary step during a traditional manufacturing operation?

Secondary process

Primary process

Final assembly

Quality control

Answer explanation

The term 'Secondary process' refers to the use of additive manufacturing (AM) as an intermediary step in traditional manufacturing, enhancing efficiency and allowing for complex designs before final production.

What additive manufacturing method involves sintering granulated material to create a part?

Powder bed fusion (PBF)

Fused deposition modeling (FDM)

Stereolithography (SLA)

Laminated object manufacturing (LOM)

Answer explanation

Powder bed fusion (PBF) is an additive manufacturing method that uses a laser to sinter granulated material, typically metal or plastic powders, layer by layer to create a solid part, making it the correct choice.

What AM process did manufacturers develop in the 1990s that allowed them to produce metal parts?

Direct metal laser sintering (DMLS)

Selective laser melting (SLM)

Electron beam melting (EBM)

Binder jetting

Answer explanation

In the 1990s, manufacturers developed Direct Metal Laser Sintering (DMLS), which enabled the production of metal parts through a layer-by-layer process using a laser to sinter powdered metal, making it a key advancement in additive manufacturing.

MULTIPLE CHOICE QUESTION

3 mins • 1 pt

What AM material is available in filaments, liquids, and powders and used in material extrusion and selective laser sintering (SLS)?

Polymer

Metal

Ceramic

Composite

Answer explanation

Polymers are versatile materials available in filaments, liquids, and powders, making them suitable for both material extrusion and selective laser sintering (SLS) processes, unlike metals, ceramics, or composites.
