Exploring the Strength of 3D Printed and CNC Machined Metals

In the world of materials testing, uncovering the strongest contenders can lead to some surprising revelations. Recently, a series of destructive tests were conducted on various materials, including 3D printed plastics, 3D printed metals, and CNC machined metals. The goal? To determine which materials would emerge victorious in the battle of strength and durability.

Unveiling the Test Setup

A robust one-ton test rig served as the cornerstone of this study, providing a consistent platform for evaluating the materials' performance. This setup, although a bit "pinker" this time around, remained unchanged from previous tests, now equipped with enhanced data tracking capabilities.

Delving into 3D Printed Metals

The journey into the realm of 3D printed metals began with a comparison of different print settings. From standard prints to maximum wall infills, each setting provided valuable insights into the materials' resilience. However, the real game-changer came with nylon carbon fiber parts, boasting continuous fiber rings of glass, carbon, and Kevlar for unparalleled strength.

Spotlight on Metal Parts

Transitioning to metal components, the spotlight shifted to aluminum, 316 stainless steel, and titanium—all crafted through advanced Selective Laser Melting (SLM) processes. The titanium standout, with its impressive performance, showcased unparalleled strength, albeit at a higher cost compared to other 3D printed metals.

Showdown: 3D Printed vs. CNC Machined Metals

The ultimate face-off ensued as CNC machined metals entered the arena. Surprisingly, the 3D printed counterparts outshined their CNC machined rivals in terms of tensile strength. Titanium, once again, emerged as the undisputed champion, showcasing exceptional durability that left competitors in the dust.

Summary of Findings

In conclusion, the results of the tests revealed a clear trend—the 3D printed metals reigned supreme in terms of sheer strength, outperforming their CNC machined counterparts. Despite the higher cost associated with materials like titanium, the unmatched strength-to-weight ratio solidified their position as industry frontrunners.
