2024 STEM Semester I Review

Front

What does FDM stand for in 3D printing?

Back

Fused Deposition Modeling

Front

Which part of the 3D printer holds the filament spool?

Back

Filament holder

Front

What is the purpose of slicing software?

Back

To convert 3D models into layers for printing

Front

What is the function of a raft in 3D printing?

Back

To stabilize the base of the print

Front

Which two factors affect the strength of a 3D print the most? Options: Filament type and slicing software, Shell thickness and infill percentage, Nozzle diameter and print temperature, Build plate calibration and layer height

Back

Shell thickness and infill percentage

Front

A print has weak and brittle parts. What settings should you adjust to improve the strength of future prints?

Back

Increase infill percentage and add more shells

Front

You want a design with a smooth finish and strong structure. Which slicer settings should you prioritize? Options: High infill, low layer height, and multiple shells; Low infill, tall layer height, and single shells; High infill, no supports, and no raft; Moderate infill, tall layer height, and fewer shells

Back

High infill, low layer height, and multiple shells

Front

A filament spool runs out midway through a print. What steps would you follow to resume printing successfully?

Back

Replace the filament, purge the nozzle, and resume the print

Front

A MakerBot print shows weak adhesion to the build plate during initial layers. What should you check or adjust?

Back

Clean the build plate and use a heated bed

Front

You are creating a prototype for a moving part with tight tolerances. Which slicer settings should you modify for the best result?

Back

Decrease layer height and ensure proper scaling of dimensions
