Fused Granular Fabrication (FGF) 3D printing is revolutionising large-format additive manufacturing. Dyze Design, a Canadian company specialising in high-performance extrusion systems, offers with the Pulsar™ and Pulsar™ Atom two solutions that bring industrial productivity within the reach of universities, research centres and companies. On DHM-online, both can also be purchased through MEPA.
Why pellet printing
Compared to classic filament extrusion, pellet printing offers decisive advantages for professional and research applications. Material costs are reduced by up to 10 times: pellets cost a fraction of the equivalent filament. Productivity is enormously higher: the Pulsar achieves 2.5 kg/hour compared to 50-100 g/hour with a standard filament extruder. The range of materials is radically expanded to include compounds with high fibre percentages, very soft elastomers and custom formulations not available in filament. The mechanical properties of parts are better, closer to those of injection moulding.
Dyze Pulsar™: industrial strength
The Pulsar™ is a high flow pellet extruder designed for large format 3D printers and robotic arms. With a maximum throughput of 500 mm³/s (2.5 kg/hour) and an 1100 W heating system, it is among the fastest portable pellet extruders on the market.
The extrusion screw is optimised specifically for high-resolution 3D printing, not simply adapted from injection moulding. The triple thermal zone ensures a constant polymer temperature: the upper zone receives the cold pellets and generates more heat to melt them, the middle zone stabilises the temperature, and the nozzle heater ensures an even flow. The patented anti-shrinkage system prevents defects during travel movements.
Nozzles available from 1 mm to 5 mm in diameter. Compatible with virtually all types of thermoplastic pellets on the market, including PEEK, Ultem and PSU. Motor NEMA 23 with hardened steel gears for maximum durability.
Dyze Pulsar™ Atom: compact precision
The Pulsar™ Atom is a compact and lightweight (less than 1.5 kg, 245 mm high) version designed for advanced configurations where weight and footprint are critical, including robotic arms and unconventional printing environments.
With an optimised compression ratio and excellent flow stability, the Atom achieves a flow rate of 800 g/hour at temperatures up to 450 °C. Nozzles available from 0.4 mm to 2.5 mm. Motor NEMA 17 with 6.23:1 gear ratio for precise control. Compatible with open-source firmware (Marlin, RepRap, Klipper) and common control boards.
Applications for universities and research centres
Dyze extruders are particularly suitable for research and development of new materials (testing of custom formulations in small quantities), large-format rapid prototyping (parts of 1 m³ and more), study of extrusion and rheology processes, circular economy projects with recycled materials, and advanced training in materials engineering and additive manufacturing.
