Maybe you used it to crank out a prototype over the weekend. Maybe you tested a jig design before committing to a machined version. Or maybe you dismissed it as “that desktop stuff with all the layer lines.” Well, a lot has changed. Today’s industrial FDM machines aren’t just prototyping toys. They’re engineering tools—capable of building durable, functional, repeatable parts that hold up in the shop and in the field. But to use FDM well, you need to know how…
