Is steel stronger in compression or tension?
Buyer: I’m working on a support frame design. I keep wondering—Is steel stronger in compression or tension? Engineer (Prime): That’s a classic materials question! Steel performs well in both—but technically, steel is slightly stronger in tension than in compression, especially in structural applications where buckling matters. Let’s unpack what that really means. Is steel stronger […]
Is CNC a metal fabrication?
Buyer: I’m building a custom metal part and got two quotes—one for CNC, the other for fabrication. Is CNC a form of metal fabrication? Engineer (Prime): Good question. CNC machining and metal fabrication often overlap, but they’re technically different processes. Let’s break down what each means, how they’re used, and when they connect. What are […]
What materials Cannot be 3D printed?
Buyer: I’ve been expanding into 3D printing and need to know—what materials cannot be 3D printed? Engineer (Prime): That’s a great question. Most people only focus on what can be printed. But there are several materials that either can’t be printed at all, or pose safety, technical, or legal issues. Let’s walk through them. What […]
