Pellet extrusion cuts the costs of industrial-scale 3D printing

Pellet extrusion technology aims to optimize the 3D printing of larger and heavier objects: The raw material is cheaper than coiled filament.

In future, Titan Robotics will be offering 3D printers that support pellet extrusion . At North American trade show RAPID + TCT 2018 , the manufacturer presented a custom Atlas printer from its portfolio. Most traditional models use coiled filament, which is significantly more expensive to manufacture. The new solution from Titan Robotics, on the other hand, facilitates the direct processing of pellets,

whereby different materials are used for different applications: from soft, rubber-like materials through robust high-performance composite materials, such as a 50/50 composite of glass-fiber reinforced nylon and carbon fiber-reinforced polyetherimide. Existing Atlas printers can be retrofitted for pellet printing. The manufacture of large-scale parts using composite pellets is, however, not a completely new innovation: Oak Ridge National Laboratory has already leveraged this technique to print a fully functional excavator .
