HotEnd BCN3D by E3D-Online

The BCN3D factory offers a wide range of HotEnd optimized by E3D-Online for its 3D printers,with independent double head (IDEX), to get the most out of all the impressions.

Many users would like to achieve the best finish in the shortest possible time. This is possible thanks to the independent dual extruder, by using a HotEnd with a smaller nozzle diameter for the outer walls and a HotEnd with a larger nozzle size for filling. This combination is also favourable for 3D printing where supports (PVA or HiPS) are needed, thus shortening printing times.

The available nozzle diameters are: 0.3 mm, 0.4 mm, 0.5 mm (stainless steel), 0.6 mm (brass or nickel-plated hardened steel), 0.8 mm and 1 mm.

The HotEnd with nozzle of 0.3 mm (High Quality) is ideal to get great finished parts, great detail and small size, especially when using common materials such as PLA. Another advantage that presents is the possibility of making sharp corners and small radii, something necessary to manufacture threads and spirals.

The HotEnd with a nozzle of 0.4 mm or 0.6 mm are the most common, versatile and used. With these diameters you can get quality finishes in acceptable printing times. A part are valid for all types of material, from the common (PLA and ABS), to technicians (PC and PC-Max) or those that contain fibers.

The HotEnd with a nozzle of 0.8 mm or 1 mm (High Flow) are the fastest. Thanks to its diameter and because it has a larger heating block than usual, thus providing greater heat transfer to the material, large pieces can be made in a shorter time interval. If the surface finish is important, you can use these nozzles for the filling in combination with smaller nozzles (0.3mm or 0.4mm) and thus get a good surface finish in record time. With the use of 0.8mm or 1mm nozzles we recommend that you use the larger purge tank, available to download and print in the following link.

To complete this range of HotEnds, BCN3D has a HotEnd with a 0.5 mm nozzle made of hardened stainless steel and the Hotend X, with a 0.6 mm nozzle made of nickel-plated hardened steel. These hotends are a must-have for all users who are thinking of using materials with abrasive fibres, such as carbon fibres  (PLA-Carbon Fiber or Nylon-Carbon fiber CF15) or metallic fibers (PLA-Conductive, PLA-Stainless Steel and PLA-Magnetic). In addition to its compatibility with fibre materials, this HotEnd is also compatible with all other materials, making it the ideal choice for users thinking of pushing the limits of their BCN3D 3D printer.

You can easily identify the diameter of the nozzle according to the number of holes:

Number of holes	Nozzle diameter	Compatibility
	0.3 mm	Sigma R19, Sigmax R19
	0.4 mm	Sigma R19 Sigmax R19 Sigma D25 Epsilon Series
	0.5 mm (acero inox)	Sigma R19 Sigmax R19
	0.6 mm	Sigma R19 Sigmax R19 EpsilonSeries
	0.8 mm	Sigma R19 Sigmax R19 Sigma D25 Epsilon Series
	1 mm	Sigma R19 Sigmax R19 Epsilon Series
	0.6 mm (Hotend X)	Epsilon Series

Regardless of the diameter of the HotEnd nozzle and the nozzle material used  the internal geometry is essential to ensure proper operation, free of jams and high performance. For this reason, BCN3D has maintained the proportions of the geometry of all its nozzles always combined with a HotEnd "full metal", with high quality materials and with a surface finish of the super smooth internal walls. 

By being able to combine two nozzles of different diameter, the number of possibilities is very large.

Thanks to all the above, it has never been so simple and efficient to make a double extrusion.
