This upgrade unlocks the full potential of your machine, allowing you to finish massive prints in a fraction of the time
The Bambu High Flow Hotend (0.8mm Hardened Steel) is the ultimate heavyweight champion for speed and volume on the H2 and P2S platforms. By combining the massive 0.8mm nozzle diameter with an optimized high-flow melt zone, this unit delivers the maximum possible throughput for large-scale models and abrasive industrial materials.
This upgrade unlocks the full potential of your machine, allowing you to finish massive prints in a fraction of the time while maintaining incredible structural strength. This is a fully integrated, high-performance unit (0.8mm nozzle, heater, and heat break are inseparable) designed for a seamless, toolless installation into your toolhead.
Features
- Extreme High Flow Performance: Engineered for maximum volumetric speed. The 0.8mm bore is the ideal choice for industrial-scale parts, thick layer heights, and slashing print times on your largest projects.
- Hardened Steel Durability: The 0.8mm Hardened Steel nozzle is built to thrive under pressure. It offers extreme wear resistance against abrasive engineering filaments like Carbon Fiber (PA-CF), Glass Fiber (PA-GF), and Glow-in-the-dark materials without the risk of widening or clogging.
- Integrated Quick-Swap Design: Maintenance made simple. Replace the entire hotend unit without messy wiring or thermal paste, keeping your production line moving.
- Active Compatibility Note: If you are running an H2D (Dual-Nozzle) setup, both installed hotends must be the same size. To use this upgrade, you must install two 0.8mm units; mixing a 0.4mm and a 0.8mm nozzle is not supported.
Real-World Maker Tips (Large Format Printing)
- Strength Over Detail: The 0.8mm nozzle isn't just about speed—it’s about strength. Thicker walls and wider extrusion lines create significantly stronger bonds, making this the go-to for functional, load-bearing parts.
- Dial in Your Cooling: Because you are pushing a massive amount of molten plastic, make sure your cooling fans are performing at their peak. For materials like PLA, you may need to slow down slightly on fine details to allow the plastic to set.
- Check Your Slicer: When swapping to the 0.8mm, remember to select the correct "0.8mm Nozzle" profile in your slicer. Your layer heights can now safely go up to 0.6mm for lightning-fast prototyping!
Compatibility
- Compatible with: Bambu Lab H2D, H2S, and P2S toolheads.
- Not compatible with: Bambu Lab P1 or X1 series printers.

Great except for one small flaw
Color: Regular - Beak, Color: Regular - Beak
Our dog likes to get at the juicy innards of every toy we buy him. We tried this one as it promised to be "bullet proof". It lasted about a week which in fairness is 6.5 days longer than most of the toys we buy last. He ripped off the wings which was to be expected and not an issue. It took him another 6 days to finally locate a weak point and break in. It appears that the tag is not made of kevlar but merely sewed on. I guess it would be better if they had just sewed it on top but they made it part of the overall structural integrity. This provided a small area of weakness which our dog located and proceeded to exploit. It's like having the death star but installing a small thermal exhaust port that allows for access to the very core of the station. Makes little sense. Overall I am pleased with the overall sturdiness but in the end this toy had a small design flaw that my dog was able to locate and exploit in his neverending quest to gain access to and eat polyester fiber stuffing

STRONG AS A MONSTER (albeit a cute one)
Color: Large - Billy the Beast Monster, Color: Large - Billy the Beast Monster
My aggressive chewer ate the adorable monster's ear off on the first day, but who cares? The body of the monster has been indestructible so far (one week). My 7 month old pup cbews it for a good 10-15 minutes at a time several times per day. Great quality product and outlasting all the other toys I bought (which she destroyed in 10 minutes - even the ones rated "Level 4 toughness" from Walmart. I think it's hilarious in my photo that the monster's expression perfectly shows his disappointment about missing an ear, LOL.

King has met his match.
Color: Large - Billy the Beast Monster
I received my dog's toy this evening when I place the toy on the ground my dog King went crazy. He is a one-year-old Pitbull and love to tackle any toy he believes he can't take down, but Mr King has met his match with this toy. He was using all of his bite force to demolish the toy but the toy actually has worn him out. He ran around my yard for about 30 minutes with the toy in his mouth producing the squeaking sound from the toy as well. Hold up the toy is totally filthy with dirt almost covering the entire green and yellow belly of the toy. I have brought king mini toys in the last couple of months and this is the best toy that holds up to his energy level. I tried to retrieve the toy and place it in his dog house because it is far beyond his bedtime, but he wanted to play catch me if You can with my new toy. This is a great toy for those big energetic dogs that love to take their aggression out on maybe some furniture or perhaps that favorite shoe you do not want them to chew on. I am totally sold on this toy I brought from the seller who placed the items on the Amazon site. I plan on purchasing a another toy from the buyer to keep King energy at a low level if I can. I just checked on my dog and he actually has taken the toy with him inside of his dog house and now the toy is snugged under his left paw. I'm one of those smart owners I'm not going to even try to take it from him tonight but hopefully in the next week I can sneak it from him and it may be perhaps wash it. I did this item AA Plus

Cute, but not Maligator-proof!
Color: Small - Towering Timmy Monster, Color: Small - Towering Timmy Monster
Fun toy while it lasts. My Belgian Malinois made quick work of this little guy but still enjoys playing with its carcass. Bite Force* but not taking into account the bite force of a Mali-gator!
