• 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.
• Ability to follow written procedures, collect data carefully, and document observations clearly.
• Proficiency with Microsoft Excel, Google Sheets, or similar tools for organizing and analyzing data.
• Strong attention to detail, safety awareness, and willingness to work hands-on in a lab environment.

Preferred but not required:

• Experience with FDM/FFF 3D printing.
• Experience printing or testing engineering polymers, nylon, carbon fiber reinforced materials, or composite materials.
• Familiarity with mechanical testing methods such as tensile, flexural, impact, or compression testing.
• Experience with basic dimensional measurement tools such as calipers, micrometers, or optical measurement systems.
• Exposure to data analysis, basic statistics, Python, JMP, Minitab, or similar tools.
• Experience documenting experimental work in lab notebooks, test reports, or technical presentations.

Desired Skills and Attributes

• Curious, hands-on, and comfortable working with both equipment and data.
• Organized and detail-oriented, especially when tracking multiple material lots and test variables.
• Able to communicate technical observations clearly to engineers and scientists.
• Comfortable asking questions, troubleshooting print issues, and adapting test plans based on results.
• Interested in materials development, 3D printing, polymer composites, product quality, and manufacturing scale-up.

Physical Demands and Working Conditions

• Wear personal protective equipment including, but not limited to, a lab coat, gloves, and safety glasses.
• Precise and repetitive handling of a range of material quantities.
• Use a fume hood to prepare samples.
• Operate analytical and 3D printing equipment at a bench.
• Move long distances (such as from building to building) and be stationary for extended periods of time.

Operate a computer and other office equipment, such as a laptop, printer, etc. in a fixed location.
