WINSINN Hardened Steel Nozzle 0.4mm, Works with E3D V6 V5 Hotend Extruder for 3D Printer 1.75mm Filament (Pack of 5Pcs)

had these for a while now printing carbon fiber PLA and phosphorescent PLA on Anycubic Delta Linear Plus . No issues to date. Print normal PLA and PETG as well. I probably see fewer blockages using these than brass nozzels especially when changing filaments. Print onto Ultrabase and use 3Dlac with PETG to protect the bet surface rather than additionak adhesion.

I needed to print a lot of parts in PET-G with Carbon Fibre and needed hardened nozzles as the additional Carbon wears brass nozzles quickly. I am building a new printer.PLA was my normal filament type but had tried PETG and had some issues and the nozzle were getting covered, this was due to not using a Z offset of 0.07mm, which i only found out later, another reason for buying 5I took a chance as some people have been lucky with clone nozzles.Fitted nozzle, checked my Extrusion speeds, printed the test models and was getting 0.85mm wall thicknesses, some were 0.9mm +. Calibrated my flow which went down to approx 70% with these nozzles.Tried printing one of the parts. I had major problems getting the part to stick to the bed, I am using glass with 3DLac. never had a problem before unless there was grease or lack of adhesive.If a part had printed and looked ok, it had no strength whatsoever or I was getting delamination issues due to the lack of filamentRechecked all of my parameters, ran more tests and calibration cubes and resulting flow rate was still around 70% and could not get wall thickness anywhere near the 0.8 it should of been.Changed nozzles for new ones many times thinking it could be a nozzle issue, maybe it had got blocked because I had done something silly.After going through a 1kg spool of CF PET-G filament with these nozzles and with nothing to show for it I thought enough is enough. Even thought it could be the filament, bought a roll @£34 for 500g and still I had issues.I have never had a problem with my prints sticking to the bed or weak prints. I went back to a brass original nozzle, loaded PLA re-checked my calibration and my flowrate was back to 92.7% with a wall thickness of 0.4mm.Printed one of the parts in PLA and a couple of hours later it came out perfect, stronger than what I had been experiencing with the clone nozzle and carbon filament.Bought a pack of original V6 nozzles. Installed the 0.4 hardened nozzle, loaded the CF filament, ran my extrusion rates and calibrated my flow and it went from 70% ish to 93.35%, again I was acheiving 0.4mm walls again.Printed one of the complicated models and it came out perfect, with strength so much so i could not break it, exactly what I needed.So even though there was 5 nozzles in the pack they were all terrible. It was a frustrating lesson, time lost, wasted filament, yes I have had prints fail but not to the extent I was getting with these nozzles.As I said in my headline, I should of bought 1 original not 5 of these clones. Lesson learnt.

I wanted to use carbon fibre plastics and i needed a head that could withstand the abrasion forces it would incur. These heads do a great job and so far after many hours of printing i have had no issues.

Funktioniert mit den meisten arten an Filament (PLA, TPU ),nur mit PETG gab es Probleme da sich das extrudierte Material eher an der Düse festhält als am zu druckenden Objekt.

Fast and exactly as pictured

Haben leider für meinen Creality Cr10S Pro nicht gepasst. Gebe dennoch 4 Sterne, da es in der Beschreibung nicht ersichtlich war.Hoffe ich konnte den ein oder anderem vor dem Fehlkauf helfen. 😊

Endlich mal bezahlbare gehärtet düsen.
