Arburg's Freeformner 300-3X celebrated its world premiere at Formnext 2018. The machine is built for the additive manufacture of complex, resilient functional parts in hard/ soft cobinations.
“The Freeformer 300-3X marks another major step forward, enabling our customers to develop completely new applications,” says Martin Neff, Head of Plastic Freeforming at Arburg. “This open system can produce complex and durable functional parts in hard/soft combinations from qualified standard plastics and a support material, offers more space and higher temperatures in the build chamber and can be automatically integrated into networked production lines.”
The designation 300 stands for the available surface area of the platform in square centimetres. This is just under 50 percent larger than on the Freeformer 200-3X. The build chamber offers space for larger small-volume batches and parts with dimensions of up to 234 x 134 x 230 millimetres. “3X” stands for the moving axes of the part carrier in the x, y and z directions. The Freeformer 300-3X has three directly heated discharge units. As an option it can be equipped with only two nozzles.
According to Arburg, the company uses only high quality, durable components for manufacturing the Freeformner 300-3X: the plasticising unit is equipped with servo motors. The modern operating panel comprises a robust industrial PC with multi-touch screen. The stable machine base accommodates the control cabinets and cooling system. The closed cooling system is also available with an optional industrial-grade cooling water connection. This will allow the processing of high-temperature materials at build chamber temperatures up to 200 degrees Celsius.
A two-part build chamber door is a new feature on the Freeformer 300-3X. This means, for example, that the material containers can be refilled during ongoing operation by opening the top half of the door. The heated build chamber now only needs to be opened for inserting the part platform and removing the finished parts. Automatic opening and closing of the build chamber door as well as optional robot interfaces also enable automation of the additive manufacturing process and integration of the Freeformer in complete production lines. Above and beyond the additive manufacture of one-off parts and small-volume batches, high-volume parts can also be enhanced and customer wishes incorporated directly in the added value chain in batches as small as a single unit by combining additive manufacturing, injection moulding and Industry 4.0 technologies.
