Len Wanger works on industrial 3D printers. And I was pleased to find out that
 there's a bunch of Python in those printers as well. 

In this episode we talk about:

• 3D printers
• What are the different types of 3D printers?
• Where are 3D printed industrial parts being used?
• Why use one type of additive manufacturing over another?
• Python in 3D printing hardware.
• What are Finite State Machines, FSMs?
• Benefits of FSMs for testing, logging, and breaking a complex behavior into small testable parts.
• Benefits of simulation in writing and testing software to control hardware.
