Additive Manufacturing Engineering Intern information

What does an additive manufacturing engineering intern do?

An Additive Manufacturing Engineering Intern assists engineering teams by supporting the design, development, and testing of 3D-printed parts and products. Their responsibilities often include preparing CAD models, operating and maintaining 3D printers, conducting material and quality tests, and documenting results. Interns gain hands-on experience with additive manufacturing technologies, such as FDM, SLA, or SLS, while learning about prototyping, design optimization, and production processes. They work closely with experienced engineers to solve real-world manufacturing challenges and contribute to innovative projects.

What are the key skills and qualifications needed to thrive as an additive manufacturing engineering intern?

To thrive as an Additive Manufacturing Engineering Intern, you need foundational knowledge in engineering principles, 3D modeling, and materials science, typically gained through coursework in mechanical or manufacturing engineering. Familiarity with CAD software (such as SolidWorks or AutoCAD), 3D printing machines, and relevant safety protocols is commonly expected. Strong problem-solving skills, attention to detail, and effective teamwork help interns excel in collaborative and innovative environments. These competencies are crucial for successfully supporting additive manufacturing projects, ensuring quality, and driving innovation in production processes.

What types of projects and responsibilities can I expect as an additive manufacturing engineering intern?

As an Additive Manufacturing Engineering Intern, you can expect to work on hands-on projects such as designing and prototyping parts using 3D printing technologies, performing quality checks, and assisting with machine setup and maintenance. You'll likely collaborate closely with engineers, technicians, and production teams to troubleshoot print issues, optimize part designs for manufacturability, and document process improvements. This role provides valuable exposure to the entire additive manufacturing workflow and offers opportunities to contribute ideas in a rapidly evolving field.

What is the difference between Additive Manufacturing Engineering Intern vs Mechanical Engineering Intern?

AspectAdditive Manufacturing Engineering InternMechanical Engineering Intern
Required CredentialsEnrolled in engineering or related degree, familiarity with CAD and 3D printingEnrolled in mechanical engineering or related degree, strong CAD skills
Work EnvironmentManufacturing labs, 3D printing facilities, R&D departmentsDesign labs, manufacturing plants, research centers
Employer & Industry UsageManufacturing, aerospace, automotive, 3D printing companiesAutomotive, aerospace, industrial design firms

The Additive Manufacturing Engineering Intern role focuses on 3D printing and additive processes, requiring knowledge of specific manufacturing techniques. In contrast, the Mechanical Engineering Intern has a broader scope, covering various mechanical design and analysis tasks. Both roles are valuable entry points in engineering, but they differ in specialization and work environment.

Job description

ADDITIVE ENGINEERING INTERN (SUMMER 2027) 

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 
    • The compensation for this role: 
      • Engineering Intern/Undergraduate: $30/hour
      • Engineering Intern/Masters: $32.50/hour
      • Engineering Intern/PhD: $35/hour
    • Relocation assistance provided
    • Free daily catered lunch and dinner, and fully stocked kitchenette 
    • Casual dress, flexible work hours, and regular catered team building events
