I will do dfm analysis, cad design for manufacturing review, 3d cad engineering
Chris
About this gig
Has a factory rejected your 3D CAD file? Are you about to pay for expensive tooling but aren't sure if your design is manufacturable?
I will conduct a rigorous DFM analysis to ensure your product succeeds at the factory.
What I do:
I specialize in Design for Manufacturing (DFM). I audit existing 3D models to find and fix critical engineering flaws before you pay for mass production.
Cheap 3D models often look great on screen but fail at the factory due to undercuts, thin walls, or impossible CNC tool-paths. I solve this by performing a strict CAD design review, generating a detailed report, and optimizing your geometry so the factory accepts your STEP files instantly.
Services Included:
- DFM Analysis & PDF Error Reports
- CAD Design Review for CNC & Molding
- Manufacturing Optimization (Cost reduction)
- Fixing unprintable/un-moldable geometry
- Wall thickness & draft angle correction
Why choose me:
- Prevents expensive factory rejections
- Certified Mechanical CAD Engineer
- Confidential NDA reviews
Software: SolidWorks | Fusion 360
Message me your 3D file for a professional DFM review!
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 exactly is a DFM Analysis?
DFM stands for "Design for Manufacturing." It is an engineering review process where I analyze your 3D CAD file to ensure it can actually be built by real-world machines (like injection molds or CNC mills) without failing or costing too much money.
What file formats can you review?
I can review industry-standard neutral formats like STEP (.stp) and IGES (.igs), as well as native SolidWorks (.sldprt, .sldasm) and Fusion 360 files.
Will you actually fix the CAD errors, or just point them out?
If you order the Basic package, I provide a detailed PDF report pointing out the errors so your original designer can fix them. If you order Standard or Premium, I will personally fix the CAD geometry and send you the optimized, factory-ready STEP files.
an you optimize a part to make it cheaper to CNC machine?
Absolutely. CNC machines struggle with sharp internal corners and deep pockets. I will optimize your CAD design by adjusting geometry to drastically reduce the machining time, which lowers your manufacturing cost.
Will you sign a Non-Disclosure Agreement (NDA)?
Yes, I conduct CAD reviews for highly confidential startup projects daily. I am more than happy to sign your NDA before you send me your files.
