    In this video, I break down the most common product design mistakes that quietly increase costs, extend lead times, and push your job to the bottom of the priority list. If you're developing a physical product, working with CNC machining, injection molding, casting, or fabrication, this is essential Design for Manufacturing (DFM) knowledge.

    We cover tight tolerances, sharp internal corners, missing draft angles, undercuts, unnecessary cosmetic finishes, exotic materials, poor assembly planning, and more, plus how to become the kind of customer manufacturers actually want to work with. If you want lower quotes, faster production, and better supplier relationships, this video will change how you design.

    ✅ Cheat sheet: 👉 https://shorturl.at/5qSGX www.rebeleng.us If your prototype worked perfectly on your desk, that’s exactly why it might fail in mass production. In this video, I explain why prototypes lie — and how manufacturing exposes every shortcut you took. We cover the biggest mistakes first-time physical product founders make when moving from prototype to production, including tolerance stackup, material changes, 3D printing vs injection molding, tooling costs, assembly errors, and production speed. A prototype proves an idea. Mass production proves discipline. If you're bringing a physical product to market, this will help you avoid costly rework, blown tooling budgets, and painful manufacturing delays. ⏱️⏱️VIDEO CHAPTERS⏱️⏱️ 0:00 – Why Prototypes Fail in Mass Production 0:52 – The Prototype Confidence Trap 1:12 – Proof of Concept vs Production Reality 2:03 – Variation, Tolerances & Why Parts Stop Fitting 2:29 – 3D Printing vs Injection Molding Problems 3:25 – Assembly Errors in High-Volume Manufacturing 4:19 – Tolerance Stackup & Six Sigma Explained 4:44 – Material Changes That Break Working Designs 6:54 – Tooling Costs, Undercuts & Manufacturing Risk 10:55 – The Mindset Shift: Design for Learning, Not Completion
