Applying Layer Means TRIZ Cases

PCD or PcBN-lined 3D printing nozzles resist abrasive wear and leakage, improving print precision and reducing material contamination.

A modular polygonal nozzle reduces flow turbulence and porosity while improving layer adhesion and simplifying worn insert replacement.

A superhard PCD or PcBN conduit surface helps 3D-printing nozzles resist abrasive wear and limit material leakage.

This case shows how a semi-flexible inner needle maintains coaxiality and tubular structure while passive stirring blends materials.

Intake comminution increases bulk density, allowing a compact screw extruder to homogenize coarse granulates without a long compression zone.

A blowing device sprays fluid through a nozzle to cool ejected thermoplastic material and reduce solidification time.

Temperature control elements cool fiber guide components to prevent overheating and clogging, ensuring continuous automated fiber placement.

Composite titanium and teflon zones reduce hot area to prevent material adhesion and control extrusion precision.

Targeting the reverse side of a thermoplastic fiber bundle with a laser emitting device prevents scorching and reduces heating time during automated placement.

A hydrodynamic nozzle introduces concentric curable sheath and core fluids to form extruded shapes.

A plasticization device uses an integrated refrigerant flow path within the screw drive case to cool the motor.

A 3D printer extrusion head uses a knurl gear and compression wheel to drive filament with precise mechanical traction.

Multiple-zone plate heaters dynamically adjust thermal profiles to minimize material degradation while maintaining high extrusion rates.

A composite material laminating device positions a cutting blade within compaction roller grooves to slice sheets directly at the press point.
