Additive Manufacturing Engineering Co-op - Spring 2027

Role details

About This Role

===================

Ready to shape the future of manufacturing? As an Additive Manufacturing Engineering Co-op at Rennscot MFG, you'll be at the forefront of additive manufacturing technology while building a comprehensive skill set across advanced manufacturing processes. This hands-on role puts you in the center of our additive manufacturing operations, where you'll work with cutting-edge 3D printing technologies, optimize build processes, and support post-processing workflows.

What You'll Do

==================

• Support Additive Manufacturing Operations

• Plan, setup, and execute additive manufacturing builds using industrial 3D printing systems
• Optimize build orientation, support structures, and process parameters for quality and efficiency
• Post-process additively manufactured parts including support removal, heat treatment, and media blasting
• Troubleshoot build failures and drive continuous improvement in additive processes
• Develop and refine manufacturing processes for new additive technologies and materials
• Engineer Better Processes

• Design and fabricate work holding fixturing for post processing additive components
• Contribute to process development, refininf build layouts, and support removal strategies for improved quality
• Participate in root cause analysis and corrective action for production issues
• Document manufacturing processes, build parameters, and setup procedures for repeatability
• General Support

• Support other departments (e.g., Quality, Subtractive Manufacturing, Assembly) as needed based on business demand
• Attend team meetings and contribute actively to discussions, bringing a fresh perspective and a willingness to learn
• Complete an end-of-term summary documenting key contributions, lessons learned, and recommended improvements for handoff to the engineering team.
• Support other projects and assignments as needed.

What We're Looking For

==========================

• You've Got the Foundation

• Currently enrolled in an accredited Bachelor's Degree program in Mechanical Engineering, Manufacturing Engineering, Industrial Engineering, or a related field.
• Interest in additive manufacturing technologies and processes
• Familiarity with CAD software (Fusion 360, SolidWorks, or similar)
• Exposure to Build preparation software (Bambu Studio, Magics, 3DXpert, nTop, PreForm)
• Strong attention to detail and eagerness to learn
• Ability to work both independently and collaboratively
• Bonus Points If You Have

• Experience with additive manufacturing systems (FDM, SLA, SLS, metal printing, etc.)
• Knowledge of additive design principles and topology optimization
• Experience with additive post-processing techniques

Who You Are - Skills & Abilities

====================================

• Future-focused – You're excited about how additive manufacturing is transforming industry
• Technically curious – You want to understand both the art and science of manufacturing
• Hands-on learner – You'd rather build and iterate than just read about it
• Process-minded – You see manufacturing as a system and love optimizing it
• Problem-solver – When a build fails or a process breaks down, you're energized to figure out why
• Detail-oriented – You know that parameters matter and documentation prevents problems
• Cross-functional – You're comfortable moving between additive, subtractive, and other manufacturing processes
• Improvement-driven – You're always asking "how can we make this better?"
• Adaptable – You thrive in a dynamic environment where priorities shift and technologies evolve
• Collaborative – You work well with machinists, engineers, and other team members to get results

Physical Requirements
