Project details
Bring your product idea to life with professional mechanical engineering, 3D printing, and prototype validation services.
I help startups, inventors, and businesses transform concepts into functional prototypes that can be tested before manufacturing. Unlike basic CAD modeling services, my process focuses on real-world functionality, manufacturability, assembly, fitment, and design validation to reduce costly mistakes during production.
With extensive experience in SolidWorks, product design, Design for Manufacturing (DFM), and prototype development, I provide engineering-driven solutions that help clients move confidently from concept to production.
Whether you need a simple prototype, design optimization, assembly verification, or a complete product development package, I can support every stage of the process.
Services include:
• 3D CAD Modeling
• Product Design & Development
• 3D Printing Preparation
• Functional Prototyping
• Design Validation
• DFM Analysis
• Engineering Drawings
• Manufacturing-Ready Deliverables
My goal is to ensure your product is not only visually appealing but also functional, manufacturable, and ready for the next stage of development.

• 2D Manufacturing Drawings
• Exploded Views & Assembly Drawings
• BOMs & Manufacturing Documentation
• FEA / Structural Design Validation
CONCEPT TO MANUFACTURING
I don't just create 3D models.
I develop mechanical products with real-world manufacturing, assembly, functionality, durability, tolerances and cost in mind.
My typical product-development workflow is:
Concept → Engineering → 3D CAD → Mechanical Design → Prototype → Testing → Design Improvements → DFM/DFA → Manufacturing Drawings → Production Files
Whether you have a rough sketch, existing prototype, STL file, previous CAD design, or only an idea, I can help convert it into a practical and manufacturable engineering solution.
DESIGN FOR MANUFACTURING
I design products for processes including:
• Injection Molding
• CNC Machining
• 3D Printing
• Sheet Metal Fabrication
• Laser Cutting
• Welding & Fabrication
• Machined Metal Components
During design development, I consider important manufacturing details such as wall thickness, draft angles, undercuts, fillets, tolerances, clearances, fastening methods, assembly sequence, material selection and production cost.

WHAT YOU WILL RECEIVE
Depending on your project, deliverables can include:
• Native SolidWorks CAD files
• STEP / STP files
• STL files for prototyping
• DXF / DWG manufacturing files
• Detailed engineering drawings
• Assembly drawings
• Exploded views
• BOMs
• Manufacturing-ready documentation
• Product renders and presentations
If you're developing a new product, improving an existing design, solving a mechanical problem, or preparing a design for manufacturing, send me your requirements, sketches or existing files.
I can help take it from concept to a functional, production-ready product.
