Welcome to Rapid Design Insights. Today we dive into a new article titled “Design for 3D-Printing” from Rahix’ blog. The author emphasizes that 3D printing demands a unique design philosophy built on rules of thumb and practical examples. He outlines three universal objectives: “Design according to force,” “Design according to manufacturing method,” and “Design according to cost.”

A cornerstone rule is to align tensile forces parallel to the print surface, since “most strength comes from the part’s surface, not the infill.” To ensure portability across printers, use chamfers on horizontal edges and fillets on vertical ones, improve holes with a teardrop shape, and “avoid the necessity of support material” through clever orientation or sacrificial layers.

And as the author says, “If you can’t make it precise, make it adjustable.” These rules help you create stronger, more accurate, and efficient 3D-printed parts.
