- Bed mesh
- A measured map of build-surface height variation used by firmware to compensate Z motion during early layers.
- Bridging
- Extruding material across an unsupported gap between two anchored regions.
- Brim
- Extra connected outlines around a part that increase first-layer contact area.
- Elephant foot
- An outward bulge at the bottom of a print, often caused by excessive first-layer compression or heat.
- Extrusion multiplier / flow
- A profile factor that changes the commanded amount of material. It should refine a healthy extrusion system, not hide mechanical faults.
- Ghosting / ringing
- Repeated waves near corners caused by vibration, acceleration, mechanical looseness or resonance.
- Heat creep
- Heat travelling too far up the filament path, softening filament before the intended melt zone.
- Infill
- Internal structure that supports top surfaces and changes weight, stiffness and print time.
- Layer shift
- A sudden horizontal offset when the machine loses or changes its expected axis position.
- Linear / pressure advance
- Firmware compensation that changes extrusion during acceleration and deceleration to improve corner and line consistency.
- Non-manifold mesh
- Geometry that does not define a clean printable solid, such as open edges, internal faces or impossible intersections.
- Overhang
- A surface extending outward beyond the layer below; quality depends on angle, cooling, speed and material.
- Partial clog
- A restriction that still permits some extrusion but causes inconsistent or insufficient flow.
- Retraction
- Pulling filament back during travel to reduce ooze; excessive retraction can create other failures.
- Seam
- The location where a perimeter starts and stops on each layer.
- Support interface
- Dense support layers placed immediately beneath the model to improve support and control removal.
- Thermal runaway
- A safety error indicating that measured heating behavior does not match the controller’s expectation.
- Volumetric flow
- The volume of material extruded per second; a key limit for hotend performance.
- Warping
- Dimensional change from cooling and shrinkage that lifts corners or curves the part.
- Z offset
- The calibrated vertical relationship between the nozzle and build surface at the first layer.
