Additive Manufacturing
Additive Manufacturing, also commonly known as 3D printing, is a modern way of making parts and products by building them layer by layer from materials like plastic, metal, or composites. Unlike traditional manufacturing that cuts away material, this process adds material only where needed. It's like building with digital Lego blocks - the machine follows a computer design to stack material precisely. This approach allows engineers to create complex shapes that would be difficult or impossible to make using traditional methods. When you see this term in resumes, candidates might also call it "3D printing," "rapid prototyping," or "AM."

Example Interview Questions
Senior Level Questions
Q: How would you implement additive manufacturing in a traditional manufacturing environment?
Expected Answer: Should discuss cost analysis, equipment selection, staff training needs, quality control processes, and integration with existing production workflows. Should mention experience leading such transitions.
Q: What strategies do you use to optimize part design for additive manufacturing?
Expected Answer: Should explain how to redesign parts to reduce support materials, optimize build orientation, and improve part strength while reducing production time and costs.
Mid Level Questions
Q: What are the main differences between various 3D printing technologies?
Expected Answer: Should be able to compare common technologies like FDM, SLA, and SLS in terms of costs, materials, accuracy, and suitable applications.
Q: How do you ensure quality control in additive manufacturing?
Expected Answer: Should discuss material testing, process monitoring, post-processing inspection, and common quality issues and solutions.
Junior Level Questions
Q: What software tools are used in additive manufacturing?
Expected Answer: Should be familiar with basic CAD software, slicing programs, and machine control interfaces used in 3D printing.
Q: What are the basic steps in preparing a part for 3D printing?
Expected Answer: Should explain the process from 3D model creation to slicing, including basic setup parameters and common preparation steps.
