David B.

Mechanical Engineer | Machine Designer | Prototype & Product Developer

With over 30 years of hands-on engineering experience, I design and develop products, precision machines, mechanisms, laboratory instruments, automated processes, and custom equipment that work reliably under demanding conditions. Clients bring me in when they need a skilled designer with advanced SolidWorks skills to bridge the gap between a concept at any stage and a fully functional, manufacturing-ready system. My skills include: Expert SolidWorks Engineering: I build robust, clean 3D CAD models, top-down assemblies, and precise production drawings optimized for manufacturing. Accelerated Prototyping: I combine professional design skills with in-house rapid prototyping and local access to CNC machine tools. This allows me to test and iterate quickly, and prove mechanical concepts early. Cross-Functional Systems Integration: I integrate mechanical systems with electronics, optics, fluidics, pneumatics, software, lab-ware, and biological systems. Core Engineering Capabilities: Medical & Laboratory Automation – I design systems incorporating automated fluid dispensing, motion control, and advanced analytical techniques. Robotics & Precision Motion Control – Implementing multi-axis motion, power transmission systems, and machine vision components. Custom Mechanisms – I design precision custom mechanisms for novel applications. Design for Manufacture – I am a machinist and fabricator with a manufacturing background. I bring that knowledge and experience to bear whenever I design a part or an assembly. Ready to de-risk your development timeline? Click the "Invite to Job" or "Send Message" button on the right.
