Additive Engineering Internship (Fall 2026)

Freeform•Los Angeles, CA

3d•Onsite

About The Position

Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation. By treating manufacturing as a single integrated system, we unlock a new era of innovation where complex hardware is designed, built, and scaled without limits. As an Additive Engineering Intern at Freeform, you will contribute to the development and scaling of our advanced metal 3D printing processes, including design for additive manufacturing (DFAM) feedback, print file preparation, toolpath automation, part quality analysis, and end-to-end process improvement. You will work closely with mechanical, electrical, software, and manufacturing engineers to support all stages of print development for high-volume production. Interns at Freeform own meaningful cradle-to-grave projects. Using first-principles thinking, you will help define test methods, evaluate solutions, iterate quickly, and synthesize information from engineering drawings, in-situ machine data, post-processing results, and inspection data to draw conclusions that improve printing and downstream machining processes. 3D printing experience is not required to be successful here - we look for smart, motivated, collaborative engineers who love solving hard problems and creating amazing technology!

Requirements

Currently enrolled in a bachelor’s degree in mechanical or aerospace engineering from an ABET accredited university or college
Hands on design experience from internships or engineering clubs such as FSAE, Baja SAE, solar car, rocket club, robotics club, or similar
Strong grasp of mechanical engineering fundamentals and comfortable taking a first-principles approach to solving problems

Nice To Haves

Advanced degree (Master's, PhD) in mechanical or aerospace engineering
Experience with metal 3D printing or additive manufacturing processes
Experience with process development for metal additive manufacturing
Scripting experience in MATLAB or similar tools for toolpath generation
Experience with DFM and GD&T
Experience with CNC machining
Passion for improving the state of metal 3D printing
Comfortable working in fast-paced, ambiguous environments and iterating quickly (comfortable building the plane as we fly it)
Strong communicator who collaborates across disciplines and proactively seeks support when needed
Willing to take ownership of tasks big and small, with a hands-on, problem-solving mindset
Strong work ethic with a refuse-to-fail mindset
Demonstrated indicators of excellence and/or achieving success against adversity (i.e. top academic performance, leadership in engineering clubs, first-generation college student, or other examples of resilience and achievement)

Responsibilities

Own a cradle to grave project that delivers meaningful impact to critical print factory capabilities or customer print workflows
Support all stages of print development including design for additive manufacturing feedback, file preparation, printing, post-processing, and quality control
Analyze in-situ data and post-print part quality to drive continuous improvement in system performance
Use first-principles thinking to define problems, develop test methods, evaluate solutions, iterate, and provide technical recommendations
