Additive Manufacturing Summer Intern information

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.

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 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 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.

Job description

ADDITIVE ENGINEER (NEW GRAD 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 Engineer at Freeform, you will play a critical role in advancing our metal 3D printing technology, including machine functionality, part quality analysis, print file preparation and generation, and DFAM recommendations for some of the world's largest manufacturers. You will own projects from cradle to grave as a responsible engineer, taking customer designs from concept through printing, testing, and delivery. You will develop a fundamental understanding of the printing factory and leverage your technical insights to advance system capabilities using a first principles mindset.

3D printing experience is not required to be successful here, rather we look for smart, motivated, collaborative engineers who love solving hard problems and creating amazing technology!

Responsibilities:

  • Understand printing system capabilities and roadmap, and work with internal engineering teams (mechanical, electrical, software) to implement solutions that further automate the printing process for high volume production
  • Drive all stages of print production development, including design for additive manufacturing (DFAM) feedback, file preparation, printing, post processing, and quality control
  • Analyze in situ data and post print part quality to drive continuous improvement
  • Use first principles thinking to understand problems, define test methods, evaluate solutions, iterate, and provide technical recommendations to internal and external stakeholders
  • Document application requirements and objectives, statements of work, standard operating procedures, next steps, and action items to align all internal and external team members
  • Interface with external customers to communicate Freeform's technical capabilities; work with customers on improving Design for Additive Manufacturing (DFAM)
  • Contribute to Freeform's internal technology development with feedback from internal and external stakeholders via detailed design and systems level improvements

Basic Qualifications:

  • 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
  • Full life cycle hardware design experience from hand calcs to CAD to fabrication and testing
  • Well versed in 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, particularly LPBF (Laser Powder Bed Fusion)
  • Process development experience for metal additive manufacturing
  • Scripting experience in Matlab (or similar) for toolpath generation
  • 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
  • Experience working with internal and/or external customers
  • Mechanical systems design experience
  • 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.
  • Our fast-paced, cross-functional environment is built on close collaboration, and as such, this role requires full-time onsite presence (five days a week), with very limited exceptions.

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.
  • Benefits
    • Significant stock option packages
    • 100% employer-paid Medical, Dental, and Vision insurance (premium PPO and HMO options)
    • Life insurance
    • Traditional and Roth 401(k)
    • Relocation assistance provided
