STEM 3D Printing & Maker Spaces 3

Question 1

A student's first layer is not adhering to the print bed. Which is the FIRST corrective action an educator should suggest?

Accepted Answer

Level the print bed and adjust nozzle Z-offset

Answer

Poor first-layer adhesion is most commonly caused by an incorrectly leveled bed or improper Z-offset, which must be corrected before other adjustments.

Question 2

In the context of maker spaces, which design thinking phase occurs immediately BEFORE prototyping?

Accepted Answer

Ideate

Answer

In Stanford's design thinking model, the Ideate phase (generating solutions) directly precedes the Prototype phase.

Question 3

Which file format is universally required to send a 3D model to slicing software for FDM printing?

Accepted Answer

.STL

Answer

The STL (Standard Tessellation Language) file format is the industry standard for transferring 3D models to slicers for 3D printing.

Question 4

A teacher wants to integrate 3D printing with mathematics. Which project BEST reinforces geometric volume concepts?

Accepted Answer

Designing and printing containers of specified volumes and comparing calculated vs. measured capacity

Answer

Designing containers to a target volume directly applies volume formulas and connects mathematical calculation to physical, measurable results.

Question 5

What is the primary advantage of using supports in 3D printing?

Accepted Answer

They allow printing of overhanging features that would otherwise droop or fail

Answer

Support structures hold up overhanging geometry (typically anything over ~45° from vertical) during printing so it doesn't collapse before the layer below solidifies.
