3D Printing Basics Video Quiz https://bit.ly/3dprintingquiz

What is the most common type of 3D printing?

• Fused Deposition Modeling (FDM)

• Resin 3D printing

• Stereolithography (SLA)

• Selective Laser Sintering (SLS)

Answer explanation

The most common type of 3D printing is Fused Deposition Modeling (FDM). It is widely used due to its affordability and ease of use.

What are the main parts of an FDM 3D printer?

• Resin vat, LCD, laser, projector

• Bed, hot end, extruder, Gantry

• Filament spool holder, SD card holder, sensors

• Power supply, logic board, stepper motors, screen

Answer explanation

The main parts of an FDM 3D printer are the bed, hot end, extruder, and Gantry. These components work together to create the desired 3D prints.

What is the file format used for 3D models in 3D printing?

• STL

• IGES

• OBJ

• STEP

Answer explanation

The file format used for 3D models in 3D printing is STL. STL is widely supported and commonly used in additive manufacturing processes.

What is the purpose of support material in 3D printing?

• To provide structure for overhanging parts

• To add color to the print

• To improve adhesion between layers

• To increase the strength of the print

Answer explanation

Support material in 3D printing is used to provide structure for overhanging parts.

What is the recommended layer height for a 0.4mm nozzle?

• 0.3mm

• 0.08mm

• 0.2mm

• 0.1mm

Answer explanation

The recommended layer height for a 0.4mm nozzle is 0.1mm. This ensures optimal print quality and accuracy.

Which filament type is known for its strength and ductility?

• PETG

• PLA

• ABS

• Nylon

Answer explanation

PETG is known for its strength and ductility, making it the correct choice.

What is the purpose of infill in 3D printing?

• To increase the weight of the print

• To improve the surface finish

• To add flexibility to the print

• To reduce printing time and material usage

Answer explanation

The purpose of infill in 3D printing is to reduce printing time and material usage.

What is the most common method of transferring G-Code files to a 3D printer?

• USB drive

• SD card

Answer explanation

A Stereolithography (SLA) printer uses a vat of UV curable resin to create 3D prints.

What is the most common filament used in 3D printing?

• PLA

• PETG

• ABS

• Nylon

Answer explanation

PLA is the most common filament used in 3D printing because of its ease of use, affordability, and wide availability.
