CUSTOMER SPOTLIGHT

This month we're featuring work by Matthew Metcalf, who sent us these pictures of the ball and socket armatures he makes for stop motion puppets. He says:

"I am a stop motion animator specializing in machining ball and socket armatures for stop motion puppets. I machine each individual part on a tormach CNC Mill and braze rods onto pre-made stainless steel balls to make each joint. I used 1018 steel in the past, but have moved onto 303 stainless steel as it won't rust over time."

WHAT YOU'RE SAYING

"I just wanted to say that I'm glad there is such a place to make ordering "already cut" materials that is quick and easy. I just finished building my CNC machine, and just haven't had the $$$ to buy another band-saw yet, and wasting material, and tooling isn't smart; but it's very convenient to have pieces ready to be machined, and easy to choose. I saw the writing on your web page that no piece is too small. No kidding huh? Cool! Have a great day."

DID YOU KNOW...?

...a new heat treatment technique may make it possible to 3D print gas turbines and jet engines?

fine grains transform into columnar grains

Manufacturers have been looking for ways to 3D print turbine blades, which, in addition to being faster and cheaper, would allow them to create more complex and efficient blade shapes. However, until now there has been one major obstacle: creep.

Creep = "a metal's tendency to permanently deform in the face of persistent mechanical stress and high temperatures."

The problem arises because 3D printing creates a crystal structure that is very fine grained. But the new heat treating technique transforms these fine grains into larger "columnar" grains which are much more durable.
