COSMM: An Undergraduate Laboratory for Engineering and Manufacturing Complex, Organic Shapes Using Nature as a Template
The COSMM (Complex/Organic Shapes and Multiple Materials) Laboratory at California Polytechnic State University, San Luis Obispo provides undergraduate biomedical engineering students with the equipment to import geometric and mechanical property data from existing biological structures into a virtual environment where they can be analyzed, modified and output using layerwise manufacturing techniques. Input (touch probe, laser scanner, destructive scanner for optical images of internal geometry, CT/MRI/Ultrasound Imaging), Computer Manipulation (surfacing, feature extraction, freeform modification of 3D geometry using a haptic device, CAD manipulation and feature addition using a combination of surface, solid, and voxel modeling, and FEA analysis), and Output (Rapid Prototyping equipment including commercial systems and custom equipment capable of creating complex composites and gradient materials) are combined into an integrated system for analyzing and incorporating biological data into product designs. This laboratory supports sophomore-level introduction to design classes, junior-level CAD/modeling/simulation classes, a two-quarter senior design sequence, and multiple Senior Projects, Masters Theses, and industry-sponsored applied research projects. Recent laboratory projects have included creating soft tissue models for medical device development, producing a mechanically accurate spinal replica, creating medically accurate FEA and physical models of the human heart, and manufacturing complex gradient composite materials and scaffolds for tissue engineering.
California Polytechnic State University has an earned reputation as a proponent of the hands-on, laboratory-based, learn-by-doing approach to education. We have also won a reputation as a college whose students are steeped in open-ended problems and underpinned by an understanding of design and the process of design. As part of our newly-created Biomedical Engineering Department, it was our goal to create a flexible, modular, expandable laboratory that would provide support across the entire spectrum from early design exposure for students to advanced industry-sponsored applied research for teams of faculty, graduate students, and undergraduates.
The rapid pace of advanced manufacturing technology has resulted in highly sophisticated equipment that is both available, accessible with reasonable acquisition and operation costs, robust, and simple enough to use such that the basics can be mastered within a few laboratory periods. What began as an ad-hoc collection of this type of equipment has now sharpened focus to become an integrated system for obtaining, analyzing, and incorporating biological data into product designs. In designing the COSMM laboratory, the goals were to help retain students, provide for close industrial participation, and to provide an integrative vehicle at a critical stage in the student’s educational career. The result provides a theme for learning, through hands-on experience, key aspects of Biology, Design, Communication, Manufacturing, Problem Solving,
