A ________ is a file format that represents a 3D model as a mesh of triangular facets, commonly used for 3D printing.

________ is software that “slices” the 3D model into layers and generates the instructions (e.g. G-code) for the printer.

The set of commands that control the movement, speed, and extrusion of a 3D printer (or CNC machine) is called ________.

In FDM-style 3D printing, the material (usually thermoplastic) that is fed into the extruder and melted is called ________.

The part of the printer that melts the filament and deposits it through a nozzle onto the build surface is called the ________.

________ is the thickness of each layer in the print; smaller layer heights yield finer detail but longer print times.

The internal structure (often a lattice) inside a printed object, which you can adjust its density to balance strength vs. material/time, is called ________.

Temporary material printed to support overhanging geometry during the build, which is removed afterward, is called ________.

A portion of a model that juts out beyond what’s directly supported by the layer below; too steep an ________ may require support.

A beveled or sloped edge added (instead of a sharp 90° corner) to improve printability or aesthetics is called a ________.

The broader term for processes (like 3D printing) where parts are built up layer by layer (as opposed to removing material) is called ________.

Pulling the filament backward in the extruder during non-printing moves to reduce oozing or stringing is called ________.

When the edges or corners of a printed part lift or deform from the print bed due to uneven cooling/shrinkage, it is called ________.

A calibration process applying a Proportional-Integral-Derivative controller to stabilize and maintain desired temperatures (for the hot end or heated bed) is called ________.
