not Familiar with it? Maybe it’s something you need and did not know that you need…
Delrin® acetal homopolymer (Polyoxymethylene POM) is the ideal material in parts designed to replace metal. It combines low-friction and high-wear resistance with the high strength and stiffness such applications require. It provides a wide operating temperature range (-40 °C to 120 °C) and good colorability. Delrin® also mates well with metals and other polymers and offers excellent dimensional stability in high precision molding.
DELRIN® Sheets and Delrin Rods have many of the same characteristics of industrial metals such as brass, aluminum, zinc & stainless steel. Typical properties include stiffness, dimensional stability, impact resistance, and structural strength. Delrin® 150 is standard general purpose, unfilled acetal. This grade has the best impact toughness of all unfilled Delrin products.
This is used in corporate seal molds for embossing. But seems to make a great substitute for metal.

It’s laser engravable safe. Trotec sells it but it’s not proprietary to them it’s a DuPont product.
I’m surprised I don’t see it used more. I’m sure cost has a lot to do with it but having the ability to have something with the strength of metal is very alluring.
