## Overview

This all-metal, water-cooled 3D printer hotend features a 0.4mm nozzle optimized for 1.75mm filament, enabling high-temperature printing with superior thermal stability. Designed for Titan Aqua liquid cooling systems, it supports advanced temperature sensors and offers durable, precision-machined components for consistent, professional results.

## Description

Nozzle diameter: 0.4mm; Feed inlet diameter : 1.75 diameter Inlet; We use the Red hard plastic material fittings (suitable for OD4mm guiding tube), so that the connector be more stable. Our hotend is made with high quality material, and great drilled.

Review: Built nicely, appears to work good. - Guess I'll be the first review this and I'll post my experience so far. First in all, I'm not sure what the proper system should be to get water flowing through this hot end. For now I bought fittings to use with a computer water cooling setup (pump, reservoir, and single-fan radiator.) I can tell you right now that there has to be a better way. This hot end uses the same type of hose that the filament uses for the water inlet and outlet. Because of that the small ID of 2.0MM restricts any short of high water flow. Especially since I'm using G1/4 water cooling fittings to 3/8" SAE hoses. I might try using the smallest section of the 4.0MM OD hose as possible and see if I can get better flow that way. So far I tried a print at 250C, and the temperature of the cooling block is at 28C which is my room temperature. So it seems to be working, just taking about 5 seconds to flow to the hotend and back to the single-fan radiator. As a note for others. As the description says; requires a 3.1mm temperature sensor, there is no threaded part like what I was hoping. I have a P100 sensor on it's way (need to go K-type soon) but since the heat break is the same size and thread as the E3D hotend I am using a E3D block for now. This hotend also comes with what looks like a brass nozzle. I am using a stainless steel nozzle instead. So let's talk a little about the heat break piece. It doesn't thread into the cooling block, instead it uses two set screws to lock it in place. I actually like this a bit better than the E3D screw on style. Because it won't seize in there. It's nicely machined as shown in the picture. I didn't try to use a E3D heat break, but it looks like it might be the same OD size. Only reason I'm thinking about that is if this part needs replaced in the future, probably won't be any alternatives. The heater cartridge uses the clamp style to keep it in place. Which I'm not a fan of, I'd rather have it use a set screw too. Mostly to prevent damage to the block, and instead to the heater cartridge.
Review: much better than an air blown cooled heatsink, but... - it has a few design issues, one is that you can only put water through 4 mm outer diameter PTFE tubes, that means 2 or 3 mm inner diameter, limited water flow. It could do better with an inner diameter of 6mm, but that claims an outer diameter of 10 mm... However it works fine like that too, I am printing in an enclosure that can go as hot as 200C and cooling with a fan is not the option, this sytem brings me cold water from outside the enclosure where I have a small tank, a radiator and a pump to recirculate. Here is the trick, if the pump dies, your print goes bust, be sure you buy a persitaltic pump (not an aquarium rotary pump, they are not made to go on non stop for days) and make sure you have an air blower/fan cooling the pump body or it gets too hot to run.

## Features

- Used for 1.75mm diameter filament
- Package: Only 1 hotend with 0.4mm nozzle, No wires
- the heating block with 3.1mm hole for temperature sensor will be shipped with the hotend, so that customer can use it for thermocouple like PT100, K-type and so on
- Compared with the air cooling hotend,the highly efficient liquid cooling can be effective for any currently available 3D printing materials.

### ⭐⭐ Undicht !
*by J***. on 5 November 2023*

Leider bekommt man die Schläche nicht dicht. Habe sie zum Testen eingeklebt, dann geht es gut. Leider ist der Aufwand gross das zu ändern, da nicht Eingeschraubt. Werde wohl 1/8 gewinde schneiden, und Nippel draufschrauben. Schade, sonst bleibt es kühl, mit G13 Kühlmittel.
