3D Design & Fabrication Intern — Mechanical Engineering

The role

As a 3D Design & Fabrication Intern, you will work directly with our R&D team to design, prototype, and iterate mechanical enclosures, optical holders, and functional parts for our diagnostic platforms. Expect real work — your files will be sliced, printed, and tested on the same week you design them. Design parametric 3D models for optical enclosures, housings, and jigs using SolidWorks or equivalent Prepare STL/STEP files and optimize geometry for FDM, SLA, and resin printing Set up and operate desktop 3D printers (Bambu Lab, Prusa, Formlabs) Perform dimensional validation using calipers, fit-check assemblies, and iterative re-design Collaborate with electronics and software teams for mechatronic integration Maintain a design log with version-controlled CAD files and print settings

What we expect

• B.E./B.Tech in Mechanical Engineering (2nd year or above)
• Proficient in SolidWorks (assembly, drawings, tolerancing)
• Familiar with at least one other tool: Fusion 360, CATIA, Creo, Inventor, or FreeCAD
• Understanding of GD&T, tolerances, and print-process constraints
• Comfortable with slicing software (Bambu Studio, PrusaSlicer, Chitubox)
• Good communicator; can articulate design trade-offs clearly
