Zothecula writes "In a prime example of past meets future, a Texas-based company has used a century-old classic firearm as the blueprint for the world's first 3D-printed metal gun. Solid Concepts' use of a laser sintering method to create a fully functional Model 1911 automatic pistol is the latest demonstration of the potential of 3D printing techniques in industrial processing. The company's 'The gun proves laser sintering can meet tight tolerances. 3D Metal Printing has less porosity issues than an investment cast part and better complexities than a machined part. The barrel sees chamber pressure above 20,000 psi every time the gun is fired.'"
