TEVOUP DRAGON HOTEND V2
HOTEND FOR BETTER PERFORMANCE
I was lucky enough to try this beauty the TEVOUP DRAGON HOTEND V2. I can say without a doubt it was worth all the money. Of course, the story does not start here… let's go back a little.
Introduction:
" "There were minor issues with my old hotend, but luckily the Homers team of experts was still available to me. I asked them to help because it's not nice what I'm printing. There's something wrong with my printer."”
„I sent the picture and they knew right away that all I had to do was tighten a few screws and replace the hotend. What luck I thought!"
Of course, the above story is just a joke, there was no need to change the hotend! :D
But now let's take the word seriously!
When I saw the Dragon hotend in the Homers showcase I decided I should give it a try. First only because it is beautiful. Secondly, because it is not cheap, and if it is hard, it is a straight path to high quality.
Of course the price was shocking for $ 100 already getting some poor quality 3D printer. But whoever wants to evolve makes sacrifices. As a good friend of mine, Tarek, said, "I'm not asking for permission from my wife, I'm ask sorry," so I ordered the Dragon hotend and waited up to two weeks until it arrived.
Wrapping:
When the package arrived I didn’t believe my eyes, it was so small that I thought something was missing. Dragon Hotend arrived in a cardboard-packed plastic box. The wearing parts were, however, packaged separately. True, it would be come in a kitschy box with a gold-edged brochure, but I think those are the costs they deduct from quality. I only missed a small sponge bed, which, if nothing else, would have been enough for the new hotend as an apparent defense.
But let it be, packaging is not everything. Let's see what they put in the box.
Screws, a wrench, a nozzle, and spare parts for a Teflon lock. Or some terrible-tasting gray cream pudding that turned out to be a thermal conductor to the heating block. : D It doesn't matter now, at least I won't be hot in the summer.
Specifications:
- Superior heat break performance
- Increased structural rigidity
- 450°C rated for larger temperature operating range
- Drop in replacement for E3D V6 hotend
- The HF version(High Flow Capacity) is the same overall dimensions as the standard one
- Collision will not break your heatbreak anymore
- Nozzles can be changed with one hand, without grasping the hot block Nickel plating copper alloy in the hot block will not soften at high temperatures in excess of 550℃
- Maximum extrusion flowrate test result (PLA@215C)
- E3D V6 HOTEND copper heater block 1020mm/min ≈ 40.01 mm³/second
- Dragon hotend 1150 mm/min ≈46.08 mm³/second
- Dragon hotend HF 1560 mm/min ≈62.51 mm³/second
First Impressions
Assembly:
The Dragon Hotend comes assembled, all we have to do is screw in the nozzle and lubricate the heating rod with the heat conductive paste. You may want to warm up the system to another 260 degrees and then tighten the screws a little to close it perfectly.
Then came the cold shower, where is the stand… Thanks to my technical knowledge and affinity, a diamond cutter, an industrial flex, and 2 architect engineers, I made a stand that is Compatible with Homers original parts and also secures the Dargon Hotend properly. (I have also heard reports that it will be packaged like this at the factory next to the hotend). In the meantime, I’ll share what I managed to makeing, hoping it will help you.
Software:
The Dragon hotend does not require any software settings other than rewriting the Probe Z offset or relocating the mechanical limit switch. These, in turn, are important because we can quickly punch a hole in our tray.
Material Quaility:
The core of Dragon Hotend v2.0 is made of high quality copper, which can withstand the heat. The frame is made of a durable material that is easy to clean. During the tests, 0.4 and 0.6 nozzles were used and both passed the quality test.
IMPORTANT: Before the first use, it is recommended to heat the Dragon Hotend to 210 degrees C and to tighten the screws slightly to prevent subsequent component loss due to thermal expansion.
Printing:
I tested the printer at 50-100-150-200 speeds. Yes with 200 speeds. Printing remained nice even at this speed, but due to the material overheating, small objects are already deformed minimally. The Calibration Cube remained impeccable in all cases, both in surface quality and dimensional accuracy. Benchy printing was also successful at a speed of 100 still not uneven or the texture fell apart.
Summary:
The Dragon hotend can be considered a high-end 3D printer accessory in both quality and knowledge. If you want to improve your 3D printers in both quality and time, I can only recommend the Dragon hotend. Fast, precise thanks to its material, easy to clean.
For a smoother material flow, I recommend the Titanium and BGM extruders, which also play a significant role in print quality.
