BigRep launches two new printers

BigRep has announced two new 3D printers, the Pro and the Edge, both of which were previewed at last month’s Formnext show. Both are Fused Filament Fabrication or FFF devices.

BigRep launched the Edge, a new FFF printer with a high speed extrusion system.

They are designed to be used to create functional prototypes, as well as composite tooling, enduse parts and smallnumber serial production. They use BigRep’s Metering Extruder Technology, or MXT, which is said to be up to five times faster than other extrusion systems. The filament feeding is separated from the melting and molten extrusion, which gives better control over the amount of the material being extruded and the speed it runs at. Both the Pro and Edge come with two MXT extrusion heads. They also make use of a CNC motion control system from Bosch Rexroth, which I’ve already covered earlier.

The Pro has been specifically designed for producing large-scale industrial parts and features a build envelope of one cubic metre. It has a large, temperature-controlled spool chamber allowing for continuous printing with highperformance materials, such as ASA/ABS and Nylon. It has an insulated and enclosed metal frame to maintain an 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 semiautomatic leveling. The Pro can print 600 mm/second at its finest 0.6mm nozzle.

The Edge, on the other hand, has a 1500 x 800 x 600 mm build chamber and has been designed to work with high performance materials, allowing for end-use parts, functional prototypes and composite tooling. It has a heated build chamber giving a controlled, high-temperature environment of up to 200°C in the chamber and 220°C in the print bed. The Edge also has automatic, upward-moving doors and an easy-to-use graphical interface on a large screen that enables full control over all print settings. The Edge is faster than the Pro, printing 1000 mm/s with the finest 0.6mm nozzle.

The Pro is available now while the Edge is due to be commercially released in the second quarter of 2019.
