I will be your mechanical engineer for dfm, cad assemblies and gdt
D. Caballero
About this gig
If you are a hardware startup, an inventor, or a company looking to take a concept into mass production, you need an engineering review before manufacturing.
I am a Mechanical Design Engineer with 4 years of experience in the automotive industry, designing mechatronic components and P or P+T sensors for heavy-duty and commercial vehicles. I specialize in bridging the gap between a conceptual CAD model and a fully manufacturable, production-ready product.
What I will do for your design:
- DFM Analysis: Draft angle verification, uniform wall thickness checks, rib-to-wall ratios, boss design, and sink mark prevention.
- CAD Optimization: Direct modification of your SolidWorks or STEP files to resolve manufacturing bottlenecks, eliminate impossible undercuts, and ensure proper tool parting lines.
- Professional 2D GD&T Drawings: Creation of strict manufacturing drawings defining tolerances, datums, to ensure your parts assemble perfectly in real life.
Why choose me? I apply rigorous Tier-1 and OEM automotive engineering standards, DFMEA principles, and root-cause analysis to ensure structural integrity and improve your manufacturing costs.
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.

Mechanical Design Engineer with 6 years of experience in parametric design, specializing in Design for Manufacturing (DFM) and GD&T. I turn conceptual CAD models into fully manufacturable, production-ready designs. With a background in the automotive sector designing mechatronic components and sensors, I excel at optimizing injection molding, milling tolerances, and complex assemblies. I offer engineering solutions that reduce manufacturing costs and prevent production failures. Let me help you optimize plastic parts, create technical drawings, or structure top-down CAD assemblies.
FAQ
What file formats do you need to start the DFM analysis?
To perform a thorough analysis and make CAD updates, I prefer native SolidWorks files (.SLDPRT / .SLDASM) or high-quality neutral formats like .STEP or .IGES. Please also provide any specific material requirements or manufacturer constraints
What exactly do you check during the Injection Molding DFM review?
I evaluate the core constraints of plastic injection: sufficient draft angles for ejection, uniform wall thickness to prevent warping, proper rib and boss dimensions to avoid sink marks, and I identify undercuts that would require e
Will my product idea remain confidential?
Absolutely. I operate under strict professional engineering ethics. Your intellectual property is completely safe, and I am more than happy to sign your Non-Disclosure Agreement (NDA) before you share any files.
Do you design products completely from scratch?
This specific Gig is focused on optimizing and preparing existing 3D concepts for manufacturing. However, I do offer full-cycle product design and top-down assembly structuring. If you need a design from scratch, please message me for a custom offer.
