I will 3d cad mold, mechanical product design, injection mold design and manufacturing
Liam M
About this gig
Need professional 3D CAD mold, mechanical product design, injection mold design, or DFM for your product? I help turn your idea, sketch, or existing CAD model into an accurate, functional, and manufacturing-ready sketch.
I solve common manufacturing problems such as poor geometry, insufficient draft, incorrect wall thickness, difficult parting lines, weak features, and designs that are costly or difficult to produce.
What I offer:
3D CAD product & mechanical design
Injection mold des!gn
DFM and manufacturability optimization
Product redesign and engineering improvements
Draft angles, wall thickness & parting lines
3D assemblies and technical drawings
Prototype and manufacturing-ready CAD files
My specialty: combining 3D CAD mold design, mechanical design, product plan, injection molding, and DFM to create practical, accurate, and production-focused solutions.
Whether you have a concept, prototype, existing CAD model, or manufacturing challenge, I can help.
Send me your requirements, sketches, references, or CAD files today and lets turn your idea into a production-ready product.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

FAQ
What do you need to start my project?
Send your sketches, images, dimensions, existing CAD files, product requirements, or reference designs. I’ll review the information and confirm what is needed before starting.
Can you design a product from a sketch or idea?
Yes. I can transform your concept, sketch, or reference into a detailed 3D CAD product and mechanical design optimized for prototyping and manufacturing.
Do you provide injection mold design and DFM?
Yes. I provide injection mold design and DFM with considerations for draft angles, wall thickness, parting lines, manufacturability, and production requirements.
Can you improve or redesign my existing CAD model?
Absolutely. I can review your existing 3D CAD model, identify potential manufacturing issues, and make mechanical/product design improvements for better functionality and manufacturability.
What file formats can you deliver?
Depending on your project, I can provide STEP, STL, SLDPRT, SLDASM, SLDDRW, DWG, PDF, and other commonly requested CAD formats.
Will my design be ready for prototyping and manufacturing?
I focus on manufacturing-ready design and DFM, including practical geometry, tolerances, draft, wall thickness, and production considerations. Final production suitability depends on the manufacturer's process, material, tolerances, and requirements.
