BigRep unveiled a significant breakthrough in Thermoplastic Extrusion (Fused Filament Fabrication – FFF). BigRep’s new proprietary MXT® will power its new BigRep Pro 3D printer and set a new standard for and redefine additive manufacturing.
The BigRep PRO is the German-engineered company’s next-generation 3D printer, promising to provide engineers and designers with the ability to create functional prototypes, as well as composite tooling, end-use parts and small-number serial production. Capable of printing with high-performance materials, the BigRep PRO will firmly establish 3D printing as an innovative, added value production technology in industries such as automotive, aerospace, consumer goods, manufacturing and more.
The new printer is embedded with BigRep MXT®, an exclusive Metering Extruder Technology, and equipped with a state-of-the-art Bosch Rexroth motion control system – delivering unprecedented speed, precision and quality and IoT connectivity that fully integrates with Industry 4.0. Unlike its predecessor, BigRep MXT® establishes a clear separation between filament feeding and melting and molten extrusion, which allows for full control over the amount and speed of material extruded at any given time. This new technology is also designed to take full advantage of the innovative printing materials BigRep, in its partnership with BASF, continues to develop.
The BigRep PRO is equipped with two MXT® modular extrusion heads, which manage and synchronize the extrusion and printing operations. This translates into printing speeds of >600 millimeters per second (mm/s), when the PRO is used with its finest 0.6 mm nozzle.
“This new technology delivers the type of innovation that the industry has been awaiting, as our groundbreaking MXT® system makes our new printers five times faster – with greater precision and quality – than current extrusion speeds,” said BigRep CEO, Stephan Beyer, PhD. “This is one giant leap for additive manufacturing, allowing BigRep customers to make full use of today’s most advanced large-scale 3D printing technology.”
BigRep PRO is specifically designed for 3D printing of large-scale industrial parts and features a build envelope of one cubic meter and a large, temperature-controlled spool chamber allowing for continuous printing with high-performance materials, like ASA/ABS, nylon and more. The insulated, enclosed metal frame ensures an optimal even temperature control, while glass doors offer a view of the print. The heated print bed is mounted with polyimide foil for enhanced adhesion during the printing process, and an integrated inductive sensor allows for semi-automatic leveling.
The new technology powering this 3D printer is significant because extrusion technology has largely been unchanged for a quarter-century. The first major advancement is a result of the development partnership announced earlier this year between BigRep and Bosch Rexroth, one of the world’s leading suppliers of drive and control technologies. Through this partnership, the PRO will be the first 3D printer by BigRep incorporating a state-of-art CNC control systems and drives by Bosch Rexroth, making 3D printing a truly IoT-ready machine with full connectivity and data.
Thomas Fechner, General Manager of the Business Unit New Business at Bosch Rexroth, commented: “Thanks to professional control systems technology, 3D printing is establishing itself as an industrial manufacturing application. In terms of hardware, the CNC control system by Bosch Rexroth is delivering the necessary performance, precision and durability. In our development partnership with BigRep, we are advancing the potential of 3D printing for its use in the environment of the Factory of the Future.”
