Great Upgrade for the Kobra S1
I picked this up as a replacement/upgrade for my Anycubic Kobra S1, and it works exactly as advertised. The integrated ceramic hotend with the hardened steel 0.4mm nozzle is a big step up from the stock setup. Installation was simple and straightforward, and everything fit perfectly without modification. The heating block design keeps temperatures stable, and the hardened steel nozzle is excellent for handling not just standard PLA and PETG, but also abrasive filaments like wood or carbon fiber without wearing out quickly. The included silicone sock is a nice bonus that helps maintain even heat and reduces filament buildup on the nozzle. So far, my prints have been clean, consistent, and I’ve noticed fewer clogs compared to the stock hotend. Definitely a solid upgrade for anyone looking to get better performance and longevity out of their Kobra S1 or S1 Combo.

Terrible. It’s melting itself within 2 small prints.

A very good upgrade.
I replaced the standard Hotend with the upgrade and it's so quick in heating up so this is a second one as a spare and very easy to fit

Świetny produkt
Działa idealnie. Nieco delikatniejsza konstrukcja niż oryginału, ale w normalnych warunkach sprawdza się znacznie lepiej od hotendu producenta. BARDZO szybkie nagrzewanie.

Calienta mucho más rápido y es más resistente
Es mucho más rápido y resistente que el original, lo he usado cientos de horas en ASA sin ningún problema. Muy buenos resultados con PLA y TPU.

Top Produkt! Viel besser als das Original-Hotend
Zunächst war ich skeptisch, ob dieses Teil funktioniert. Schließlich hat es eine komplett andere Bauform als das Original. Ich wurde einen besseren belehrt. Es lässt sich mühelos einbauen, sogar einfacher als das Original. Der größte Pluspunkt ist das schnelle Aufheizen dieses Hotnends. Es geht gefühlt 5-10 Mal schneller als beim Original. Das ist gerade beim Wechseln des Filaments ein riesiger Vorteil. Nach max. 10 Sek hat das Hotend die 250 Grad erreicht und man kann die Rolle wechseln. Das Druckbild ist absolut sauber. Ich habe auch das Gefühl, dass das extrudierte Filament aus der Stahldüse glatter ist als bei der Messingdüse. Zudem soll die Düse deutlich länger halten und auch kein Problem mit abbrasivem Filament haben. Dies konnte ich bislang noch nicht testen. Ich bin mega happy mit dem neuen Hotend und bereue nicht, umgestiegen zu sein.
