500℃ High Temperature Plated Copper Heater Block Compatible with PT100 Cartridge Sensor Version V6 Hotend Titan Aero Extruder Prusa i3 MK3 MK3S 3D Printer (Copper)

Well made, has worked fine for a few years, finish is still fine. Consistent temps after tuning. Just wish it had come with a sock, had to cut another to fit and keep it on with some wire.

Normally I rely on reviews to make a decision but the options for this type of heater block is limited. There are plenty of cheap aluminum ones and one other copper plated option that got bad reviews. If you are wavering on a decision spend the $12 and go with this one. You can immediately feel the difference between this block and an aluminum one. The weight alone is impressive... I’m not sure if that’s going to negatively affect the quality of my prints or if it even makes a difference in heating. But I was able to fit a p100 thermistor, stock E3d v6 parts, and a nozzle x; I tuned it to 300 degrees and it worked perfectly. All I need now is some nylon to print. And just In case you are worried about the silicone sleeve...well that fit too.

Needed a new heater block on the E3D V6 hot end on my FLSUN QQ-S Pro. This one is more solid/clean than the old block. I'm pleased with the recent printing results. I also think this block holds the temperature setting better. Let's see how it holds up.

I was pretty skeptical at first like the other reviewers, but the first thing I noticed when I received the heater block was that it was far too heavy to be brass or aluminum, so that was good. After screwing and unscrewing the heat break a few times, the plating started to wear off on the threads (hence, 4 stars instead of five), but because of this flaw I could see that the block itself is actually copper and not some other metal. I've been using this on my FLSUN Q5 for a few weeks now and it works well, and holds heat much better than the original aluminum block it came with. If your looking to build your own V6 style hotend, I recommend this heater block.

I have a tungsten carbide nozzle. It would loosen up and leak during every print. So I replaced the heat break. Same problem. Then I tried this copper heat block. Nozzle stays tight. No more leaks. Very pleased.

Perfect fit replacement for my mk3s

I am generally not a fan of clone products as they tend to perform far worse than the original. With that said it’s a heat block, kind of hard to mess that up. At half the price of a genuine copper e3d block I’d say it’s great-threads we’re cut perfectly and a genuine e3d heatbreak screwed in easily. Now I didn’t cut it open to confirm the material but the weight is what you’d expect from copper as is the performance, solid buy for 13 bucks.

Copper retains heat at least 3X+ as well as aluminum. So with this block you should get much more consistent temperatures although you must re-tune your PID settings. Also because it holds heat better, if you combine this with a higher wattage heater cartridge, you should be able to pump out filament considerably faster without the block cooling off. Both of these observations seem to be holding true for me. On the other hand, I'm getting a lot more stringing despite considerable time and effort spent trying to re-tune all my settings (including but not limited to retraction). I'm not an utter noob but neither am I highly experienced so your mileage may vary, and don't take my word as gospel.

Good quality , machined well

Ce bloc de chauffe en cuivre nickelé est vraiment de bonne qualité, la finition est très soignée et son montage est très aisé, les divers filetages étant vraiment parfait. Je n'ai par contre mis que 4 étoiles car bien que le cuivre soit cher, je trouve que le prix de vente de ce bloc de chauffe est élevé malgré sa grande qualité.

I think i like this heatblock better than the original. Had to replace the original due to snapped heatbreak. This heatblock heats quickly, seems to hold temperature consistently. You cant use a rubber heat sock with this block, but it has a slippery coating to reduce filament sticking, had no issues so far, its stayed clean quite well

Da sich Wolframcarbid-Düsen in Aluminium-Blöcken durch den extrem unterschiedlichen Wärmeausdehnungskoeffizienten kontinuierlich lockern sowie das Gewinde im Innern verformen und zerstören, benötigt man einen härteren Heater-Block. Kupfer leitet Wärme noch besser als Aluminium, ist härter und weniger verformbar (E-Modul). Die dreifache Dichte von Kupfer zu Aluminium ist beim geringen Gewicht des Blocks im Verhältnis zum gesamten Druckkopf kein signifikanter Nachteil. Der Block ist von den Abmessungen identisch zu einem E3D-V6-Block und ist ein perfekter Ersatz.

Habe diesmal einen Noname-Kupfer-Heizblock bestellt, da die Bestellungen von e3d nun durch den Einfuhrzoll noch teurer werden. Bisher bin ich mit diesem Heizblock vollauf zufrieden. Auch die Silikonsocken von e3d und die Nozzle, etc. passen perfekt.
