I previously reviewed the Trianglelabs Matrix and it performed really well. This makes the thermal performance a bit better while also requiring less airflow. The main difference between the Matrix and the Hemera is the use of a bi-metal heat break instead of the regular titanium heat break used on the Hemera. This will make the Trianglelab Matrix an easy upgrade because of the huge selection of mounts and fan ducts available. It’s cooled by a 4010 fan and it maintains compatibility with all the designs made for the Hemera. The heatsink has a different design, but otherwise it looks remarkably similar. The Trianglelabs Matrix has a big resemblance of the E3D Hemera. With a bowden setup, you will be severely limited by the speed you can print these materials, and on some printers it’s not even possible.Ī lot of people upgrade to a direct drive extruder specifically for printing flexibles faster and with better quality. Even so, regular speeds of about 60mm/s should be easily achieved without much ringing.Īnother benefit of running a direct drive extruder is the possibility of printing flexible filaments, like TPU, TPE, Ninjaflex and others. Because the motor is next to the hotend and it moves during printing, you won’t be able to push speeds as high as with a bowden setup. There’s also a drawback for direct drive extruders and that’s weight. Retraction will be much lower compared to a bowden setup, and you can even set it to 0 with some direct drive extruders and proper calibration of linear advance/pressure advance. Because the filament path from the extruder to the nozzle is much shorter compared to a bowden setup, you will be able to tune your extrusion much easier. The main reason to buy a direct drive extruder is to have better control of your filament. Therefore, E3D Hermes it is not compatible with other Nema 17 motors and you'll not be able to swap the motor with either a compact but powerful/ slimline motor or other 3rd party motors.5 Wrapping Up Why buy a Direct Drive Extruder? *Please note* - w hilst the custom motor is similar to a Nema 17, it isn’t a standard Nema 17. A further benefit of optimised airflow is that we can supply a quieter fan. To put it simply, we’ve made printing with flexibles super easy! Improved AirflowĪn optimised heatsink ensures airflow is diverted up and away from both the HotEnd and the heated bed, reducing the risk of warping and uneven stresses forming in the printed part. As a result of closely tolerancing all the components, we are also able to achieve a clearance gap between filament drive wheels and heatbreak of approximately 100µm. This means that flexible filaments such as TPU’s can be printed with similar print speeds to PLA. Filament ConstraintĪlong with a very short filament path from hobb to meltzone, the filament is tightly constrained. In addition, there are also 4 convenient T-slots on each side of the motor for flat mounting plus other accessories. Ultimately creating a smaller, more compact system with a lower overall part count. This allows the motor itself to be part of the assembly, incorporating features such as bearing pockets and mounting points. CompactĮ3D Hermes uses a custom motor (based off a NEMA17 frame) modified with our faceplate designs. The round bottom of the profile strongly resists filament debris wedging into the drive gear and in almost all cases it’s self-cleaning as any debris simply falls off the teeth. Individually CNC cutting each hobb allows for a round-bottomed root, with a tooth that curves upwards to a robust, sharp tip. E3D Hermes is a dual-drive system with a hardened stainless steel drive train.
