So far compatibility and performance have been identical to the original nozzle with no change in accuracy or layer lines. Everything heats up correctly and installation was easy. I can't speak as to durability since I've only completed a few print jobs so far. Review: Yup, this is the package. - The perfect spare parts. The fit perfectly. And we have had no problems with printing. ## Features - Precision & Consistency: Engineered with a precision-machined nozzle, this A1 Mini Hot End ensures ultra-smooth and stable filament extrusion. It delivers exceptional layer-to-layer adhesion and fine detail reproduction, significantly reducing common issues like under-extrusion, stringing, or layer shifting for flawless 3D prints every time. - Wear-Resistant Hardened Steel: Made from premium hardened steel, this A2L nozzle is built to withstand the most abrasive filaments. It offers superior durability, outlasting standard brass nozzles by up to 5-10 times, making it the perfect long-term, cost-effective upgrade parts. - Leak-Free: Featuring precisely cut threads and a perfectly flat sealing surface, this replacement part guarantees a tight, leak-proof seal. This precision engineering eliminates the risk of filament oozing or clogging, ensuring consistent back pressure and reliable extrusion even during long, complex multi-hour prints. - High-Temperature: The A1 Mini Hotend operates reliably at high extrusion temperatures (up to 350°C). The A1 nozzle is fully compatible with high-performance engineering materials like ABS, ASA, PETG, PA (Nylon), and PC. It maintains structural integrity and thermal stability under extreme conditions, allowing you to expand your printing capabilities beyond standard PLA. - Quick Swap & Compatibility: Designed as a direct plug-and-play replacement, this A2L nozzle hotend is perfectly compatible with Bambu Lab A1, A1 Mini, and A2L Series hotend assemblies. No additional modifications or tools are required for installation. - Upgrade Removable Nozzle: The A1 hotend features a replaceable nozzle that has a threaded, removable hardened steel nozzle. It allows you to replace a worn or clogged nozzle in minutes, rather than replacing the entire hotend, reducing running costs. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.3 out of 5 stars 905 Reviews | ## Images ![2 Pack 0.4mm A1 Mini/A1/A2L Hotend Kit Hardened Steel Nozzle for Bambu Lab | Removable Wear-Resistant Nozzle, Quick-Swap, High-Precision Leak-Proof, Heat-Resistant up to 350℃, with 2PCS Silicone Socks - Image 1](https://m.media-amazon.com/images/I/61I7CV68ufL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Recommended - will buy again when needed... *by D***C on September 2, 2026* I bought these for the A1. So far compatibility and performance have been identical to the original nozzle with no change in accuracy or layer lines. Everything heats up correctly and installation was easy. I can't speak as to durability since I've only completed a few print jobs so far. ### ⭐⭐⭐⭐⭐ Yup, this is the package. *by J***S on August 27, 2026* The perfect spare parts. The fit perfectly. And we have had no problems with printing. ### ⭐⭐⭐⭐⭐ They work, and work well! Will buy again as needed. *by A***N on August 12, 2025* So as everyone knows, there aren't any profiles for the Kobra 3 Max for larger nozzles than 0.4mm. However, it didn't take much to get these going. So far only used the 0.6mm and the prints are silky smooth even at 0.3mm layer lines. The nozzle outperforms the stock one in quality imo. I go through a kg of filament every few days so they get used quite a bit, but not a farm or anything just a hobby. Rare stringing, getting speeds around 80-100mm/s but still shaves off 1-2hours a print easy and more on even larger prints. Here are the settings I use in Anycubic Slicer Next Don't forget to go into printer settings on the actual printer and set the nozzle to 0.6/0.8. This will cause it to do a vibration calibration and PID for the new non-standard nozzle. If you don't do this it won't match the slicer profile and won't print. If you are wanting to do the 0.8mm nozzle just change the line widths to 0.82 and the two other options to 0.85 and then layer height 0.4mm plus the rest of the changes. Each new item that is different than the previous print I do a calibrate flowrate from the touch screen so don't even mess with the volume 11-12 in the settings that can be adjust but might be useful to avoid calibrating. Only have to redo it on spool/color change Process: Advanced on Layer height: 0.3 First Layer and Layer: 0.3 You can still use finer lines and could do 1st layer 0.3mm and Layer after that as 0.1mm. Which still prints surprisingly fast. Line Width(s): All 0.62 Except: First Layer 0.65 Sparse Infill 0.65 Precise Wall: Enabled Printer Settings: Basic Information Tab Support Multi bed: Enabled Z offset: -0.02 Extruder Tab Nozzle Diameter: 0.6 Layer Height limits: 0.1/0.3 (Min/Max) Wipe distance: 5 Filament Profile: I'm using PETG so just adjust the temps or whatnot. You want to bump your temps 5-10C at the nozzle Cooling: No fooling for first 5 layers Full fan speed at layer 6 Part Cooling Fan: 10/100 (Min/Max) Keep Fans always on: Disabled Don't slow down for outer walls: Enabled This keeps the fan in use only when needed and at a rate it calculates. Since with PETG you don't want a lot of fan. Settings Override: Retract on layer change: Enabled Wipe while retracting: Enabled Wipe Distance: 5mm Retract amount before wipe: 0 Sorry for no images, not a fan of sharing any IRL photos on the internet. ## Frequently Bought Together - HzdaDeve 2 Pack A1 Mini/A1 Hotend Print Head Hot End Kit Extruder Upgrade High-Temperature 0.4MM Hardened Steel Nozzle Replacement with 4PCS Silicone Cover Sock for Bambu Lab 3D Printer Accessories - 2PCS A1 Mini Upgrade Hotend Kit, 3D Printer Print Head Hot End Heating Block Kit with 0.2mm Hardened Steel Nozzle and Silicone Socks for Bambu Lab A1/A1 Mini - OVERTURE PLA Filament 1.75mm PLA 3D Printer Filament, 1kg Cardboard Spool (2.2lbs), Dimensional Accuracy +/- 0.02mm, Fit Most FDM Printer (Black 1-Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.ke/products/663750634-2-pack-0-4mm-a1-mini-a1-a2l-hotend-kit](https://www.desertcart.co.ke/products/663750634-2-pack-0-4mm-a1-mini-a1-a2l-hotend-kit) --- *Product available on Desertcart Kenya* *Store origin: KE* *Last updated: 2026-09-13*
