The Seven Deadly Sins of 3D Printing
Portals: tinyurl.com/38pdkzuc
There are 7 rules you should never ignore when designing parts for 3D printing. These design principles can make the difference between parts that are strong, reliable, and easy to manufacture—and parts that constantly create problems.
In this video, Gabe breaks down the seven major rules we use when designing for production 3D printing. We cover why layer lines can actually be an advantage, how to simplify your first layer, when to use chamfers instead of fillets, why you shouldn’t rely on slicer settings to fix your design, and how micro features can create strength exactly where you need it.
We also cover designing around supports and why FDM 3D printing often benefits from thicker, chunkier geometry instead of thin injection-molding-style features.
The goal is simple: design for the manufacturing process you’re actually using. When you understand what 3D printing does differently, you can create stronger, cleaner, more reliable parts that are much easier to manufacture at scale.
