My Portfolio
FAQ
What is included in your Mechanical Design service?
My Mechanical Design service includes 3D CAD modeling, mechanical components, assemblies, and design modifications based on your specifications and functional requirements.
Can you provide a Technical Drawing for my factory?
Yes. I provide detailed 2D technical drawings with dimensions, tolerances, and manufacturing information to support accurate production and assembly.
Do you offer DFM Engineering for new products?
Absolutely. I provide Design for Manufacturing (DFM) reviews to optimize product geometry, material selection, and manufacturing processes while reducing production complexity and costs.
What files will I receive for a Product Prototype?
You can receive STEP, STL, and other agreed CAD formats suitable for 3D printing, rapid prototyping, and further product development.
Is 3D CAD Rendering included in the packages?
3D CAD rendering can be provided as an additional service. It helps you visualize your product through realistic images for presentations, marketing, and product demonstrations.
How accurate will the Technical Drawing be?
I create precise technical drawings based on your supplied dimensions and specifications, including appropriate tolerances to support manufacturing and assembly.
Can you help with complex Mechanical Design assemblies?
Yes. I can develop multi-component mechanical assemblies, perform interference checks, and organize parts to ensure proper fit and functionality.
Why is DFM Engineering important for my project?
DFM helps ensure your product can be manufactured efficiently. It identifies potential production challenges, reduces unnecessary complexity, and helps minimize manufacturing costs.
Can I use your 3D CAD Rendering for my website?
Yes. I can provide high-quality product renders suitable for websites, e-commerce listings, presentations, promotional materials, and crowdfunding campaigns.
What is the process for developing a Product Prototype?
The process starts with reviewing your concept, sketches, or specifications. I then develop the 3D CAD model, review the design for manufacturability, make necessary adjustments, and prepare the required files for prototyping.
