Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time you improved how a printer ran, through maintenance or parameter changes, and what it changed.
What they are checking: Ownership of equipment performance beyond just pressing start on builds.
Tell me about a time you learned a new additive platform quickly. How did you get up to speed?
What they are checking: Ability to pick up emerging technologies, which the posting calls out directly.
What would you do
Three engineers each say their prototype is the top priority this week. How do you schedule the machines?
What they are checking: Fair, transparent scheduling and the willingness to push priority calls up when needed.
An engineer sends a file that you can tell will warp or fail as designed. What do you do?
What they are checking: Giving useful design-for-additive feedback before wasting a build, without overstepping.
About the work
You run SLS, SLA, DLP, DMLS and FDM. How do you decide which technology a given prototype should be built on?
What they are checking: Matching process to the part's purpose, material, accuracy and timeline instead of defaulting to one machine.
Walk me through how you prepare and nest a full SLS build to get the most parts out of one run.
What they are checking: Build preparation skill that balances packing density, part quality and thermal effects.
A DMLS build fails partway through overnight. What do you check first?
What they are checking: Systematic troubleshooting of metal printing failures like recoater crashes, supports or parameters.
Talk me through your post-processing steps for an SLA part, from the platform to the engineer's desk.
What they are checking: Knowledge of washing, curing, support removal and finishing that decides final part quality.
How do you handle powders and resins safely, especially metal powder for DMLS?
What they are checking: Safety awareness around combustible powders and chemical hazards in the lab.
How do you check that a printed part is accurate enough for the test it is going into?
What they are checking: Inspection habits that make sure prototypes are good enough to trust test results.
How do you keep track of material lots, machine hours and build history?
What they are checking: Record keeping that lets the lab trace a bad part back to its cause.
