Pellet extrusion is going to be a paradigm shift within the additive manufacturing sector, as it presents opportunities for improvement that are not possible with filament materials.
Currently, the format of most 3D printing materials is the filament. It is composed of threads of variable diameters and are rolled on spools. In order to obtain a material in filament format, a melting process of its previous state must be done; this state is the pellet, small portions of agglomerated or compressed material.
The transformation from pellet to filament, although it facilitates the transport, extrusion and compatibility of material with most 3D printing platforms on the market, it increases it’s cost, the possibilities of contamination, it limits it’s grammage and it negatively influences the resistance of the products manufactured from it.
Under the philosophy of improving the processes, costs and productivity of customers who rely on additive manufacturing solutions, Tumaker has developed a new large format 3D printer with direct pellet extrusion technology. In this way, there is no limitation on the amount of useful material, offering an unlimited supply to create parts as complex, large or heavy as you want. The use of pellets eliminates the need to process the material, greatly reducing production costs. In turn, fewer manufacturing steps mean less chance of material contamination, resulting in a more consistent end product.
This type of material condition has many uses in industrial injection molding machines and offers a greater variety of plastics. On the other hand, it is ideal for scientists and laboratory work with few grams of materials, since the material used does not need a previous conversion to filament. It is compatible with any thermoplastic on the market at an exceptional price without losing its qualities.
