German RepRap, a leading German manufacturer of FFF (Fused filament fabrication) 3D printers, introduces the X400 v4 for additive manufacturing of large objects as well as for limited industrial-grade production runs. The printer handles parts with layer thickness of up to 0.1 mm.
Through the use of high-end components, including milled metal parts and drives with tight tolerances, the printer delivers a high repeat accuracy and quiet operation. New features include automatic bed leveling and a commercial-grade ventilation design. The automatic bed-leveling feature means the print bed needs to be calibrated only once, eliminating time-consuming adjustments before each print job. The ventilation design ensures consistent operating temperatures throughout each job. Several dedicated fans in the printer maintain temperatures in the extruder, around the printed object as well as in the print area. This also improves the processing of materials such as PVA (polyvinyl alcohol).
The filament tracking system automatically pauses the active print job when the filament runs out. In addition, the X400 v4 senses variances in extrusion speed that are invisible to the naked eye, and it automatically reacts to secure the printing process and prevent print job cancellation.
The X400 v4 includes an integrated industrial-grade computer and can be controlled with the touch screen and a USB interface (stand-alone printing). The printer connects to the internet through Ethernet and is controlled through a web browser.
The printer comes with a licensed copy of the Simplify3D software, which contains all the features required for manufacturing industrial-grade objects. Individual parameter settings, adjustable to object geometry, allow full control over the printing process. The software enables the use of dual extruders for printing a variety of materials and colors as well as for the repeated positioning of different objects in the print area. In addition, separate parameters can be set for printing different parts of a single object.
The DD3 dual extruder technology with a full metal hot end tops off the printer’s features. The extruder can be fitted with different nozzles to adjust for various applications and materials. Contact pressure is variable, as well, to facilitate the processing of softer materials.
