Conch Hotend® QIDI Plus4

top Druckplatte auch für technische kusntoffe wie ASA cf und so einfach perfekt immer wieder gerne hoffe sie gibt es bald für den plus 4

Works like a charm

This 3D printing hotend is a solid piece of upgrade that transforms the Qidi Plus 4 3d printer into a serious machine for additive manufacturing. The nozzle diameter of 0.4mm is a standard ratio but having better thermocouple and heating element makes printing abrasive materials whether glass fiber or carbon fiber filled 3D printer filaments easier. It's flow rate caps out around 30 cubic mm/s which is excellent for fast flow and high speed filaments when printing PLA or PETG. While the effect of minimizing VFAs and improving 3D print quality is subtle and hard to spot on specific edges the hotend does feel both precise and has a fast flow rate. Installation on the Qidi Plus 4 is somewhat straight forward as there is some thermal grease along with an Allen key to swap out the hotend. Wiring harness has both the thermocouple and ceramic heating element cabling that is shielded and runs into a mini 4p plug connector that has a satisfying latch to connect into the toolhead board. The wrench and Allen key makes the tightening easier and installation process a DIY friendly approach. Build quality of the heat spreader is noticeably wide and uses a stacked array of fins which dissipate heat evenly keeping 3D printer filament as it flows through the hotend balanced. Another factor to consider was the silicon sock that keeps the hotend from accumulating filament buildup and maintains the Qidi Plus 4 in a cleaner state. Even the 0.4mm nozzle which is fairly standard has a filament resistant brim around the edges which is rubber tacked to make cleaning the nozzle easier. While hot swapping this hot-end isn't straight forward doing a drop-in installation makes more sense because it's essentially an upgrade on the 3D printer. Overall I was quite pleased with this premium hotend which is precision engineered to make both installation straight forward and upgrades the 3D printer with hardened components. The nozzle on the bottom is a standard 0.4mm but can be swapped using rotation mechanism with the included wrench. There is a bit of prep after installing this hotend to heat up the nozzle around 350C and fasten the system to minimize any air gaps but was easy to figure out DIY installation.

Works great. I mean, its just a hotend, so it's not a complicated part, but still. Heats up way faster than the stock hotend.

The package was stiff and well made, the plate arrived spotless. The surface and technology used for the coating it’s impressive.
