I will complete product design dfm dfa manufacturing drawings
Ahmed Shawky
About this gig
Are you looking to turn your sketch, 3D idea, or electro-mechanical concept into a factory-ready product? I am a Lead Mechanical Design Engineer (M.Sc, CSWP) with over 7 years of industry expertise in turning complex ideas into high-precision, production-ready hardware.
Whether you need a custom sheet metal enclosure, an industrial sound-damping structure, or a wooden chassis optimized for CNC routing, I deliver designs built strictly for real-world manufacturing.
Services Offered:
- 3D CAD Modeling: Complex sheet metal, weldments, & parametric assemblies in SOLIDWORKS.
- Design for Manufacturing (DFM): Optimized for laser cutting, CNC machining, injection molding, & sheet metal bending.
- 2D Technical Drawings: Manufacturing blueprints with ASME Y14.5 GD&T, tolerances, & full BOMs.
- Laser-Ready Files: 1:1 scale flat-pattern DXF vector files.
- Simulation & CAE: Structural FEA and thermal CFD analysis in Ansys.
Why Choose Me?
- Certified SOLIDWORKS Professional (CSWP).
- Zero factory-floor surprises: tight tolerances & accurate bend allowances.
- Fast communication & clear technical documentation.
Let's bring your engineering project to lifesend a message today to discuss your requirements!

I am a Lead Mechanical Design & R&D Engineer with extensive experience developing mechanical products from concept through manufacturing. My expertise combines mechanical design, FEA simulation, and product optimization using SolidWorks, CATIA, and ANSYS. I approach design challenges by balancing theoretical analysis with real-world manufacturability.

FAQ
Q: What file formats will I receive with my order?
You will receive native 3D CAD files (.SLDPRT, .SLDASM), universal 3D exchange formats (.STEP, .IGES, .STL), 2D manufacturing PDF blueprints, and 1:1 scale flat-pattern .DXF vector files ready for CNC laser cutting or routing.
Q: Can you design specifically for my manufacturing process (Laser, CNC, Injection Molding)?
A: Absolutely. Every design is built around Design for Manufacturing (DFM) rules. I account for sheet metal bend allowances/k-factors, CNC tool bit radiuses, injection molding draft angles, and GD&T tolerances to ensure zero surprises on the factory floor.
Q: What do you need from me to start my project?
A: You can provide hand sketches, dimensioned rough drafts, reference photos, PDF ideas, or STEP files of existing components. Please include any specific material preferences, manufacturing methods, or key dimension constraints you have.
Q: How do you handle custom or complex multi-part mechanical assemblies?
A: For complex projects, send me a message before ordering! I will review your technical requirements and send a customized offer tailored specifically to your project's scope, timeline, and exact deliverables.
Q: Can you optimize my existing CAD model to reduce production costs?
A: Yes. I perform DFM reviews to simplify geometry, reduce material waste, adjust tolerance stack-ups, and optimize laser/CNC cutting paths to lower unit tooling and fabrication costs.
Q: Do you offer structural FEA stress testing?
A: Yes! I conduct high-fidelity Finite Element Analysis (FEA) for structural loads using Ansys to validate performance before you build physical prototypes.
Q: Will my proprietary design and intellectual property stay confidential?
A: 100% yes. All customer models, drawings, and project details are kept strictly confidential. I am more than happy to sign a Non-Disclosure Agreement (NDA) before reviewing your files if required.
