Manufacturing Engineering Co-op - Summer

About This Role

Ready to shape the future of manufacturing? As a 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.

You'll also gain valuable experience in CNC machining and CAM programming, giving you a complete understanding of how additive and subtractive processes work together to create exceptional products.

• Lead 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 surface finishing

  • Troubleshoot build failures and drive continuous improvement in additive processes

  • Develop and refine manufacturing processes for new additive technologies and materials

• Bridge Additive and Subtractive Manufacturing

  • Create, simulate, and verify CNC programs for 3-, 4-, and 5‑axis milling and turning centers using hyper
    
    MILL, ESPRIT & Fusion 360

  • Design hybrid manufacturing workflows that combine additive and subtractive processes

  • Support machining operations for post‑processing additive parts and traditional CNC production

  • Collaborate with machinists on setup, prove‑out, and first‑article validation

• Engineer Better Processes

  • Design and fabricate work holding and fixturing for both additive and subtractive processes

  • Contribute to process development, refining toolpaths and cut 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

• Keep Production Moving

  • Operate CNC machinery and additive systems to support prototype and production work

  • Perform setup, inspection, and basic troubleshooting across manufacturing equipment

  • Support continuous improvement projects focused on machine utilization and process capability

  • Cross‑train with Quality and Assembly teams based on business needs

• You've Got the Foundation

  • Pursuing a Bachelor's degree in Mechanical, Manufacturing, Industrial Engineering, or related field

  • Interest in additive manufacturing technologies and processes

  • Familiarity with CAD software (Fusion 360, Solid Works, or similar)

  • Understanding of CNC machining and subtractive manufacturing concepts

  • Exposure to CAM software (ESPRIT, hyper
    
    MILL, Fusion 360, or similar)

  • 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

  • Operated CNC machines (mills or lathes), especially Heidenhain, Okuma, & Haas controllers

  • Understanding of G‑code and machine setup

  • Can read and interpret engineering drawings with GD&T

  • Exposure to Lean Manufacturing or Six Sigma principles

  • Experience with additive post‑processing techniques

• 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…
