POM Material - What is it used for?


I am new to Snapmaker and the 3D printing, engraving and carving game. Can someone tell me what the POM material is used for - engraving, carving, both? If you engrave on it does it create a really nasty burnt plastic smell in your work area? If your CNC carve the material does it dull your bits quickly? Thanks for the help and I look forward to sharing ideas.
