Freeform
Materials Engineer (New Grad Summer 2027)
About this role
Freeform seeks a new graduate Materials Engineer for a summer 2027 internship to support materials and processes infrastructure for advanced metal 3D printing systems. You'll conduct hands-on testing, analyze material properties, and contribute to process improvements while working alongside senior engineers on cutting-edge additive manufacturing technology.
What you'll do
- Operate equipment to measure material properties including tensile strength, surface roughness, and microstructure
- Generate and track quality metrics for printed parts such as dimensional accuracy and defect distribution
- Organize, analyze, and interpret experimental data and present findings to cross-functional teams
- Work with process development to integrate materials findings into printing process improvements and machine learning models
- Support development of M&P best practices and testing infrastructure
- Assist in automating measurement and quality quantification procedures
What they're looking for
- Metals characterization and sample preparation (cutting, grinding, polishing, etching)
- Optical microscopy and materials testing techniques
- Materials engineering fundamentals and first-principles problem-solving
- Data analysis and interpretation
- Technical writing and presentation skills
- Laboratory equipment operation
- Statistical analysis software (R, JMP, Minitab preferred)
- Metal additive manufacturing processes
