A new type of extruder enables both speed and fine detail in Fused Filament Fabrication. The single extruder includes multiple nozzles each with its own valve and a high throughput melter. Valving enables shutoff and turn on of filament flow, maintaining the nozzle pressure. All valves open provides rapid printing producing wide ribbons of extruded material that enhance layer-to-layer adhesion. Fine details can be defined with a single or small number of nozzles open. The valves can be opened and closed rapidly enabling detailed edges and patterns even when printing at high speeds.
This talk will focus on description of our new multi-nozzle valved extruder design for Fused Filament Fabrication. We’ll discuss various performance attributes, modelling, and operating parameters for various configurations of the extruder (such as number and size of nozzles as well as details of the valving performance). We’ll also show examples of printing both high speed and fine details.
- Understand the approach to higher speeds without compromise
- Describe the value of useful parts at a reasonable cost
