Updated High Temperature CR-10 Plated Copper Heater Block for MK8 Extruder Creality All Metal Hotend Ender3 V2 Ender 3 pro Ender 5 Pro Plus CR10 S4 S5 3D Printer (Copper)

Great replacement. Perfect fitment

For a very similar price to stock you can pick this up instead. Sizing is prefect and installs with no issues. Better heat stability then OEM. Great upgrade.

I built a custom CR10 that runs Klipper. This was the first setup I used on it, I've since gone to a ceramic heater since it heats up better. This worked as it should and if I still used that setup I'd buy one again if needed.

This does not fit Ender 3 V2 despite the product advertised as fitting it. The holes are offset slightly too far back so the screws do not line up.

Bolt holes don't line up for my neptune 3 pro but I made it work.

Easy to install and works exactly as expected.

It was easy to install, it is a direct replacement for the stock aluminum heat block on my Ender 5 Plus and my print quality has improved with smoother prints and less stringing, especially with PETg (see the picture, this is after going through about 4 spools.) Just make sure you tune your PID (Proportional Integral Derivative - google it if you are not already aware of PID) as this changes the heating and cooling dynamics of your extruder.

Nicely machined, glad that it has to place for a cartridge style thermistor since I broke my old stock one during the swap. Install was simple, had to run PID auto tune after, definitely more conductive than the stock aluminum heat block. Do yourself a favor and buy the cartridge style thermistor... Odds are you'll need it when the stock one breaks.

Mk 8 replacement heat block for cr 10 range of printers work great

I like the weight of the block compared to the stock block on the CR10 V3. The problem was, the screws used to secure the original block to the heat sink are too short for this new heat sink. I had to drill two bigger holes half way into the block so the original screws could sit deep enough into the block so they could reach, and screw into h-sink.

Used for a all metal hotend upgrade on my Neptune 3 pro. Worked great with a screw fit thermistor and bimetal heatbreak. Could not use the original M2 bolts, had to use M2 16mm.

Ich habe mir den Heizblock als Ersatz für den defekten Heizblock meines Ender 3 Pro gekauft. Hier hatte sich nach knapp 2 Jahren Betrieb beim Eindrehen einer neuen Nozzle das Innengewinde in seine Bestandteile aufgelöst. Zuerst einmal fällt auf, dass der Kuper-Heizblock wesentlich schwerer ist (24g) als das Serien-Teil des Enders (8g), welches aus Aluminium besteht. An der Passgenauigkeit gibt es nichts zu meckern und auch die Verarbeitung kann als sehr ordentlich bezeichnet werden. Es gibt keine scharfen Kanten und die Bohrungen sind passgenau. Der Tausch erfolgt 1:1. Alle anderen Teile des Serien-Hotends können beibehalten werden. Zur Haltbarkeit kann ich natürlich noch nichts sagen, da das Teil erst wenige Stunden im Einsatz ist. Ob Kupfer nun wirklich besser ist als Aluminium sei einmal dahingestellt, aber zumindest scheint es kein Nachteil zu sein. Bisher funktioniert jedenfalls alles wie gewohnt. Daher vergebe ich 5 Sterne.

Upgrade per Neptune 3 Pro. Perfetto! Ma attenzione: i 2 buchi per le viti per il fissaggio alla stampante non sono molto larghi per far entrare la testa delle viti originali. Di conseguenza queste risultano troppo corte. Munirsi quindi di 2 viti M2x16mm in acciaio. Una volta montato tutto, l'estrusero verra' comunque a trovarsi alla stessa altezza dell'originale. Ottimo upgrade per stampare ad alte temperature.
