High-Speed Printing

Continuous Printing

Additive manufacturing techniques have seen major advances in print speeds. Continuous liquid interface production (CLIP) represents an exciting new development with immense potential. Instead of building objects layer-by-layer, CLIP produces parts through continuously advancing photo polymerization. This process enables seamless, non-stop manufacturing capable of unmatched print speeds.

CLIP works by utilizing oxygen to inhibit polymerization where the build platform is not in contact with the resin. As the platform rises steadily from the resin vat, a solid object is formed at the interface and progressively stabilized with supportive structures. Because it does not require repeatedly pausing to cure individual slices, CLIP can fabricate parts at extremely fast rates constrained only by how quickly objects can be stabilized as they emerge from the resin. Furthermore, complex designs pose no impediment and minuscule features are equally feasible with CLIP.

Parallel Printing

Besides continuous printing, parallel operations represent another avenue for heightened print efficiencies. Multiple extruders arranged in parallel deposition systems yield productivity multipliers by allowing multiple components or copies to be fabricated concurrently.

Industrial scale 3D printers put this approach into practice. One prominent parallel 3D printer utilizes six industrial FDM extruders arranged on a gantry for simultaneously producing multiple parts. Each extruder contains its own proprietary tool head enabling independent temperature controls. Parts emerge fully built from this multi-head system in the fraction of the time required for single-head printers.

Newer parallel future of 3D printing technologies show even greater multi-tasking abilities. One innovative 3D printer boasts a massive 600 print heads mounted on an innovative parallel kinematics mechanism. Individual nozzles can be controlled independently thanks to an embedded Linux-based computer yielding groundbreaking output rates.

Hardware Advances

Advancements in printer hardware systems further boost production speeds. Developments like high-temperature extruders expand the material selections enabling faster deposition of thermoplastics without sacrificing quality or strength. Linear rails and guide rods delivering ultra-smooth motion surpass conventional ball screw designs in speed and rigidity.

Control over minute layer parameters translates to finer resolutions and surface finishes. Piezo-electric print heads capable of higher deposition velocities translate to swifter part rendering. Temperature-controlled print beds ensure critical dimensional stability at productivity-enhancing print speeds. Together, these innovations in hardware enable greater control for optimized settings that propel future of 3D printing to unprecedented velocities.
