Repeatable No Methods of Instruction Laboratory Lecture/Discussion Distance Learning Lab: The instructor will guide students by example through the demonstration of performance based outcomes. Students will demonstrate the practical application of setup, execution, troubleshooting and quality assurance aspects of various forms of 3D printing. Students will setup and run a 3D print on the 3D printer that will conform to the drawing specifications for the physical development of the part. Lab objectives will be assessed by measurement of the physically produced components in comparison to the drawing guidelines. Lecture: The instructor will present to the students during lecture/presentation/discussion engineering design methodology that the student will synthesize and apply to assigned problems and then formulate a solution utilizing correct engineering design methods. Students will discuss various setup methods for additive manufacturing technology and develop individual set up guidelines for their individual 3D models. Lecture objectives will be assessed during the discussion sessions and students will prove mastery by developing a functional set up plan. Typical Out of Class Assignments Reading Assignments 1.
