Stronger filament doesn't automatically mean a stronger print, and the toughest materials can require better hardware too.
If you're looking for one winner, it's not exactly convenient that a 3D print can be "strong" in a few different ways. A rigid bracket should resist bending, while a part that gets knocked around may last longer if it can flex and recover instead of breaking. In this article, we're going to hone in on rigidity and the types of materials that work well for structural parts.
Carbon-fiber-reinforced nylon (PA-CF) and polycarbonate (PC) are two of the strongest practical materials for the kind of filament-based 3D printers…
