Canadian-based OEM Dyze Design is now officially taking preorders for its new pellet 3d printer extruder, Pulsar™. This state-of-the-art high flow rate plastic pellet extruder was designed with a single purpose: quickly and cost-effectively 3D print parts of 1 m³ and more. Pulsar™ is able to output 2.5 kg of material per hour (500 mm³/s). 

“Pellet-based extrusion is a true game changer in the 3d printing industry. It enables really high throughput, but most importantly, it reduces your material costs by up to 10 times and gives you access to new kinds of polymers, some that don’t even exist in filament format,” says Simon Duchaine, Chief Marketing Officer of Dyze Design. “There’s more and more demand for pellet-based printers or extrusion systems in the industry. Companies just want to get things done faster, at a lower cost. Pellets give you the best of both worlds.”

The Pulsar™ extruder is intended to work with pellets, also commonly known as granules, ranging from 3 mm to 5 mm. Pellets can be from popular polymers to more advanced engineering material (such as PEEK, PEAK, PEI, PVA, HIPS) thanks to its maximum operating temperature of 500 °C and its integrated liquid-cooling loop.

Optimised for industrial 3d printing

The customized screw design is optimized for 3D printing with high resolution. The triple heat zone guarantees the polymer is at a constant temperature: the top section receives cold pellets and generates more heat to melt them. Then, the middle zone stabilizes the polymer at a precise temperature. Last, the nozzle heater ensures an even flow. The Pulsar™ also features an “anti-oozing mechanism.” As the screw can’t pull molten plastic, an anti-oozing device ensures nice looking prints without any flaws, such as “hairs” appearing during linear travels.

With dimensions of 48 cm by 17 cm by 13 cm, Pulsar™ is designed for rather huge printers with a printing volume of 1m3 and more. “Pulsar™ lets you print large parts, like a chair or even a car, in a single piece,” tell Dyze’s CMO. “The extruder could actually be installed on a robotic arm. It’s a trend we start seeing. Some industrial companies already have access to robotics arms on premises, so they can simply mount an extrusion tool head to enable FDM technology,” adds Simon.

The extruder is also compatible with any standard open source firmware (Marlin, RepRap, Repetier, etc.)

Regarding supplying granules to the extruder, a hopper can be fixed on the extruder inlet to make use of gravity or an automatic feeding system can be purchased as an add-on to continuously bring pellets from a bulk container.

Last year, Dyze Design managed to do rigorous testing of the extruder through a beta program. Several industrial or large-scale 3d printer manufacturers experimented and provided feedback, such as Compound Dynamics, Filament Innovations, Tobeca, Hybster, Rapid 3D, Lynxter to name a few.

The Pulsar™ extruder is now officially open for preorders. It is priced at US$7949.
