From Partial Clog to Bed Mesh: practical explanations of the 3D-printing, slicer and calibration terms that appear throughout LayerCompass.

Illustration for Partial Clog
Problems

Partial Clog

A partial blockage: filament still exits the nozzle, but flow becomes inconsistent or collapses at higher demand.

Explain this term →
Illustration for Heat Creep
Hardware

Heat Creep

Heat travels too far up the hotend and softens filament above the intended melt zone.

Explain this term →
Illustration for Warping
Problems

Warping

Corners or edges lift from the build plate as the part shrinks and develops thermal stress.

Explain this term →
Illustration for Stringing
Problems

Stringing

Fine strands form between separated areas when molten plastic leaks during travel moves.

Explain this term →
Illustration for VFA — Vertical Fine Artifacts
Problems

VFA — Vertical Fine Artifacts

Fine repeating vertical patterns on otherwise smooth walls, often tied to motion-system excitation and speed.

Explain this term →
Illustration for Ringing / Ghosting
Problems

Ringing / Ghosting

Decaying waves that appear after corners, edges or abrupt direction changes.

Explain this term →
Illustration for Pressure Advance
Calibration

Pressure Advance

Compensates for pressure buildup and release in the extrusion system during acceleration and deceleration.

Explain this term →
Illustration for Max Volumetric Speed
Calibration

Max Volumetric Speed

The maximum stable material throughput of a specific filament, nozzle and hotend setup, measured in mm³/s.

Explain this term →
Illustration for Bridging
Slicer

Bridging

Printing a strand across open space between two supported points without support directly underneath.

Explain this term →
Illustration for Arachne
Slicer

Arachne

A wall-generation strategy that varies extrusion line width to fit geometry more intelligently.

Explain this term →
Illustration for Bed Mesh
Calibration

Bed Mesh

A measured map of build-plate height variation that the printer can compensate for during printing.

Explain this term →
Illustration for Layer Shift
Problems

Layer Shift

One or more layers are printed sideways from the correct position and the rest of the print continues offset.
