• Print standardized 3D printed test coupons using reinforced polymer filament materials.
• Record and track print parameters, including nozzle temperature, bed temperature, chamber conditions, print speed, orientation, drying conditions, and other relevant variables.
• Document printability observations such as feeding behavior, bed adhesion, warpage, surface quality, dimensional consistency, and print defects.
• Characterize filament quality attributes such as filament diameter consistency, ovality, surface appearance, brittleness, spool quality, and general handling behavior.
• Support mechanical testing of printed coupons, including tensile, flexural, impact, or other relevant tests as directed by the team.
• Organize and analyze data to compare filament lots, print conditions, and resulting mechanical performance.
• Help identify trends between filament attributes, processing behavior, and printed part properties.
• Summarize findings and provide recommendations for QC methods, product improvement, and future testing.
• Maintain clear documentation in lab notebooks, spreadsheets, test summaries, and final presentation materials.
• Follow all applicable safety procedures and maintain a clean, organized lab and printing workspace.
• Educational Requirements
• Currently pursuing a Bachelors degree in Materials Science and Engineering, Mechanical Engineering, Polymer Science, Chemical Engineering, Manufacturing Engineering, or a related technical field.
• Preferred academic standing: rising junior, rising senior, or graduate student.
• Coursework in materials science, polymers, composites, mechanical testing, manufacturing, statistics, or additive manufacturing is preferred.
• Experience Requirements
• Required:
• Hands-on laboratory, engineering project, research, or coursework experience.
• Basic understanding of engineering materials, mechanical properties, or polymer/composite behavior.
