The concept is similar to how a hot glue gun functions, only much more precise. To create these objects, 3D printers are supplied with feedstock made from various substances which are then melted into a state where they can be worked into their desired shape. The operation is controlled by software (essentially computer-aided design or CAD) that takes all the dimensions and then builds an object from scratch. That’s a grossly simplified explanation, but that’s more or less how it works tiny bits of material are put together and fused into an object.
Eventually, a larger mass begins to take shape. Then it drops another one on top of it, and another and another.
It makes a tiny drop of material, microscopic in size. Imagine a miniature nozzle on a piping bag for decorating cakes. What Is 3D Printing? What Was The First 3D Printed Gun?ģD printing, also called “rapid prototyping” and “additive manufacturing,” is a way of quickly creating an object.
