This rapid prototyping process can be used to melt titanium powder to make metal prototypes and can be up to 95% energy-efficient

E-beam melting

A prototype is needed for a hand-held toy design application. The surface roughness is not an issue and the finest features of the design have thicknesses 3 millimeters or above. The budget for prototyping is not to exceed $1500 for the ten prototypes needed. Which additive process is the most efficient for this prototyping?

FDM (fused deposition modeling)

Which of the following is NOT a good way to build teamwork? (a) Focus on personal relationships. (b) Set rules for team behavior. (c) Agree on the purpose of the team. (d) Clearly define a means of measuring team progress.

Focus on personal relationships.

Which sentence best describes someone who is motivated by performance-oriented goals?

I want to get excellent grades.

Which sentence best describes someone who is motivated by mastery-oriented goals?

I want to understand things.

This additive process doesn't need any post-modeling curing and uses ultraviolet bulbs to instantly cure and harden each deposited layer.

MJM

This rapid prototyping process uses a vat filled with photo-curable polymer that is hardened into a specific shape. It can be used with highly focused lasers that can generate features of micrometer size.

Stereolithography

Which of the following is NOT a good criterion for a new vehicle? (a) The car should be a silver color. (b) The car should be spacious. (c) The car should have at least 15 cubic feet of cargo space. (d) The car must have a backup camera.
