Dual Extruder BCN3D Sigma R19 3D Printer(A4 Printing Size)
BCN3D Simga R19 is a Spanish premium dual extruder 3D printer. Its A4 printing size is up to 210 x 297 x 210 mm, which allow users to print a large sized 3D model. Its features include:
Adopt Independent Extruder System （IDEX System）
Sigma R19 applies independent extruder system, which means 2 printing heads can move independently. The advantage to use independent dual printing head is that molten plastic can be prevented from being dripped onto a print during the dual colors/ materials printing to enhance the printing quality.
Build-in Filament Runout Sensor
When material is used up, the printer will automatically pause and will notify the user to reload the a new filament before restart the print.
Hotend designed by e3D™
Hotend designed by e3D™ has an optimized heatbreak and heatsink stuctures, which offer a better heat transfer, and more reliable and accurate extrusion under different environments will be delivered.
Bontech™ extruder with dual-drive gears has proved to be the best feeding system to ensure a reliable extrusion. This extruder can allow a more accurate extrusion rate to print 3D models with complex structure.
Innovative Printing Modes
Duplication Mode allows 2 identical 3D models to be printed simultaneously with 2 independent printing heads, while Mirror Mode mirrors the 3D model and print it in a pair of symmetric models simultaneously with 2 independent printing heads. Both of these printing modes can significantly increase the 3D printing productivity.
Able to mount enclosure
Enclosure can be mounted on the Sigma R19 to have a quieter printing environment. Also, a constant interior temperature can be obtained to prevent warping in technical materials such as ABS. Besides, the enclosure equips with a HEPA filter, which can filter out small particles that may be created during printing. (Enclosure needs to be purchased separately)
