Additive Manufacturing Summer Intern information

What types of projects and responsibilities can an additive manufacturing summer intern typically expect during their internship?

As an Additive Manufacturing Summer Intern, you can expect to work closely with engineering teams on hands-on projects involving 3D printing technologies, materials testing, and process optimization. Interns often assist in the design, prototyping, and evaluation of components, gaining exposure to both hardware and software aspects of additive manufacturing. Daily tasks may include operating 3D printers, preparing digital models for printing, conducting quality inspections, and documenting results. Collaboration with engineers, technicians, and sometimes cross-functional teams is common, providing valuable networking and learning opportunities. This role offers practical experience and can serve as a stepping stone for future careers in advanced manufacturing or engineering.

What is the difference between Additive Manufacturing Summer Intern vs Additive Manufacturing Engineer?

AspectAdditive Manufacturing Summer InternAdditive Manufacturing Engineer
CredentialsTypically pursuing or recent graduate in engineering, materials science, or related fieldBachelor's or master's degree in engineering, materials science, or related discipline; often with professional certifications
Work EnvironmentInternship setting, assisting with projects in labs or manufacturing facilitiesFull-time role in R&D, production, or design teams within manufacturing facilities or corporate offices
Employer & Industry UsageInternships offered by companies in aerospace, automotive, or healthcare industriesFull-time positions in similar industries, focusing on design, process optimization, and production

The Additive Manufacturing Summer Intern role is an entry-level position designed for students or recent graduates gaining hands-on experience. In contrast, the Additive Manufacturing Engineer is a full-time professional responsible for designing, developing, and optimizing additive manufacturing processes. Interns typically work under supervision, while engineers lead projects and make technical decisions.

What are the key skills and qualifications needed to thrive as an additive manufacturing summer intern, and why are they important?

To thrive as an Additive Manufacturing Summer Intern, you typically need a background in engineering or materials science, along with fundamental knowledge of 3D printing processes. Familiarity with CAD software (such as SolidWorks or AutoCAD), 3D printers, and possibly experience with simulation tools or rapid prototyping techniques is valuable. Strong problem-solving abilities, attention to detail, and effective teamwork and communication skills help set candidates apart. These competencies ensure interns can effectively contribute to innovative manufacturing projects and adapt to evolving technical challenges in the field.

What does an additive manufacturing summer intern do?

An Additive Manufacturing Summer Intern assists engineering and manufacturing teams with the design, prototyping, and production of parts using 3D printing technologies. Their responsibilities often include operating 3D printers, preparing digital models, running tests, analyzing results, and documenting processes. Interns gain hands-on experience with various additive manufacturing methods and materials, and may also help in troubleshooting equipment or optimizing print parameters. This role provides valuable exposure to advanced manufacturing technologies and industry best practices.

Job description

ADDITIVE ENGINEERING INTERNSHIP (FALL 2026)
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!
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

Basic Qualifications:
  • 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 Have:
  • 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)

Location:
  • Based in Hawthorne, our vertically integrated facility brings technology development, R&D, and production together under one roof. We operate at the center of LA's deep tech ecosystem, surrounded by some of the most ambitious hardware innovation happening anywhere in the country.

What We Offer:
  • We have an inclusive and diverse culture that values collaboration, learning, and making deliberate data-driven decisions
  • We offer a unique opportunity to be an early and integral member of a rapidly growing company that is scaling a world-changing technology
  • Compensation and Benefits
