Additive Manufacturing Engineering Co-op - Spring 2027

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 OperationsPlan, setup, and execute additive manufacturing builds using industrial 3D printing systemsOptimize build orientation, support structures, and process parameters for quality and efficiencyPost-process additively manufactured parts including support removal, heat treatment, and media blastingTroubleshoot build failures and drive continuous improvement in additive processesDevelop and refine manufacturing processes for new additive technologies and materialsEngineer Better ProcessesDesign and fabricate work holding fixturing for post processing additive components Contribute to process development, refininf build layouts, and support removal strategies for improved qualityParticipate in root cause analysis and corrective action for production issuesDocument manufacturing processes, build parameters, and setup procedures for repeatabilityGeneral Support Support other departments (e.g., Quality, Subtractive Manufacturing, Assembly) as needed based on business demandAttend team meetings and contribute actively to discussions, bringing a fresh perspective and a willingness to learnComplete 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 FoundationCurrently 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 processesFamiliarity 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 learnAbility to work both independently and collaborativelyBonus Points If You HaveExperience with additive manufacturing systems (FDM, SLA, SLS, metal printing, etc.)Knowledge of additive design principles and topology optimizationExperience with additive post-processing techniques Who You Are - Skills & Abilities Future-focused – You're excited about how additive manufacturing is transforming industryTechnically curious – You want to understand both the art and science of manufacturingHands-on learner – You'd rather build and iterate than just read about itProcess-minded – You see manufacturing as a system and love optimizing itProblem-solver – When a build fails or a process breaks down, you're energized to figure out whyDetail-oriented – You know that parameters matter and documentation prevents problemsCross-functional – You're comfortable moving between additive, subtractive, and other manufacturing processesImprovement-driven – You're always asking "how can we make this better?"Adaptable – You thrive in a dynamic environment where priorities shift and technologies evolveCollaborative – You work well with machinists, engineers, and other team members to get results Physical Requirements The physical demands described here are representative of those that must be met by an employee to successfully perform the essential functions of this job. Regularly stands, walks, and moves throughout the manufacturing facility for extended periods during machine setup, prove-out, and floor support activities. Frequently bends, stoops, kneels, and reaches to inspect equipment, tooling, work holding, and machined components at machine level. Occasionally lifts and carries materials, tooling, fixturing, and raw stock weighing up to 50 lbs; team lifts required for heavier loads. Regularly operates a computer workstation for extended periods for CNC programming, ERP documentation, and technical communication. Works in an active manufacturing environment subject to noise, vibration, metal chips, cutting fluids, and industrial equipment; required to wear personal protective equipment (PPE) at all times on the shop floor, including safety glasses, hearing protection, and steel-toed footwear. Manual dexterity required for operating CNC equipment, hand tools, and precision metrology instruments including calipers, micrometers, and indicators. May perform repetitive motions that may include wrists, hands and/or fingers. Visual acuity required to read technical drawings and GD&T callouts, inspect machined surfaces and features, and work with precision measurement tools.
