CNC machining is typically thought of as a technology that is so expensive and so difficult to use but it is actually very accessible. Machine costs depend on the variation of the machine but the typical rate for a 3 axis CNC milling machine is just 40 dollars an hour. There are also material costs that come with using a CNC machine and you will typically have to buy nylon power or stainless steel powder in order the operate the machine.
- 3D printing can produce parts on demand and the start up costs involved are very low and requires no tools.
- The overhead for a machine typically is two thirds the price of the CNC machine and the process of 3D printing.
- The machine rate is typically the cost of purchase divided by the total hours needed to operate the machine.
“CNC machines come in different variations. Depending on their machine architecture and capabilities the typical machine per hour differs.”
