E3D has invested a lot of time and used all of their experience to design E3D's latest and greatest HotEnd. If you would like to know more about the design process, check out this blog post, or watch the video below.
With no PEEK or PTFE in hot regions, you can reach 285C with the supplied thermistor. By swapping a thermistor for a PT100 or thermocouple (may require additional electronics) and swapping the heaterblock to copper, you can reach over 400C.
This not only allows you to print extremely high-temperature materials like Polycarbonate and Nylons but also eliminates HotEnd meltdown failures associated with PEEK/PTFE designs. There is no risk of damaging the PTFE liner through overheating.
Go from 20C to 200C in just 65 seconds - temperature control is responsive enough that you can keep the HotEnd within 0.5C of your set temperature or less with ease.
E3D has eliminated Kapton tape or any other adhesives from the assembly process of v6 E3D HotEnd. The new thermistor clamps into place with a small screw, high-temperature glass sleeving is used to insulate the thermistor legs. No soldering is needed as we supply solder-free ferrules for making heat-resistant, quick, and easy electrical connections to the thermistor legs. Most parts of the HotEnd simply screw together, the new fan duct clips into place and can be oriented in many different directions.
Building on our signature performance that allows you to print high-temperature materials we've now focussed on adding increased functionality with soft and flexible filaments. By providing a PTFE liner tube through the HotEnd that you can extend into your extruder you have the ability to add the confinement and constraint needed to make excellent quality prints with flexible filaments like NinjaFlex, FlexPLA, and FlexPolyester. This opens up a huge range of new opportunities for your printer.
(PTFE Liner only present in 1.75mm version - 3mm Bowden has partial lining - 3mm Direct has no lining)
We've kept our sharp thermal transition that gives the high-quality printing performance users have come to expect from E3D HotEnds. A sharp thermal break gives better control over filament output so you get a more immediate start and stops when extruding as well as retracts that are more effective in combatting ooze. For the user, this means sharper more accurate prints that have less stringing, oozing, or blobs on the prints.
While our default 0.4mm nozzle gives great prints with a good balance of speed, ease and resolution we are offering a range of nozzles that have special geometries that are tailored to the specific needs of how you want to print. The shape of the tip of the nozzle is key to how the E3D HotEnd extrudes and flattens a track of plastic. By matching the size of the tip of our nozzles to the width of track of plastic we are able to print with increased resolution in smaller nozzle sizes and with our larger nozzles we've customized the geometry so that you can easily lay down large layers for fast strong prints. Nozzles are easily and quickly changed out because of their hexagonal shape.
We've kept our same 16mm Groovemount dimensions from v5 to ensure that as much compatibility is maintained as possible with our extensive range of community-designed mounts. See here for examples: Thingiverse
We have an active user base on many printer forums, including RepRap Forums, Google+, SeeMeCNC, Solidoodle, Ultimaker, and many others. We also maintain our own E3D Forum. We value the community that uses our product and look to support development wherever possible - whether that means giving advice on public forums or private email support by our contact system. We stand behind our product and want to make sure every customer gets the support they need.
(Note that 3mm Bowden deviates from previous groovemount dimensions slightly - please see drawings for clarification)
