BIQU E3D Panda Revo Hotend Compatible with Bambu-Lab P1S P1P, with E3D Rapid Change Revo Nozzle, Drop-in Upgrade, High Flow Hotend Up to 40mm3/s

Great nozzle! Completely unnecessary, while it can outperform the stock nozzle in vase mode and such where you have continuous fast printing, 99% of the time it's the same speed. If you run a business and print lots of stuff in vase mode or anything where the speed can max out, this could be game changer for you.I use it exclusively for the quick swap nozzle. Unplugging those tiny connectors as much as I swap nozzles was going to be a problem in the long run.

When it comes to 3D printing, a successful upgrade for me often means it just didn’t make things worse. Very rarely does an upgrade actually make things better. However, this print head has set a new standard in successful upgrades for me. It’s just amazing to be able to unscrew the nozzle with my bare hands and swap it out with another of a different size in a matter of seconds. Not to mention the nozzles work extremely well just as good if not better than OEM nozzles. So very happy with this purchase.I do understand it is a little frustrating that the photos for other nozzles look like they come in a pack. I wish they would fix that, it is misleading. But even at $20-$30 per nozzle, it’s worth it to me for the simplicity and functionality.Thank you for making an amazing product!

I am still not a big advocate for these covers. They can help keep the heater clean from minor strings, and small failures. But they can sure make a big failure much, much worse if the filament starts to get in underneath, because it then gets redirected right up into the heatsink! This is a problem with most of the E3D style heater blocks, where the cartridges enter the side. Knock on wood, I have yet to have a catastrophic mess with the socks on heaters that top load the cartridges, like on Prusa's. But I have to run these on my Vorons with Dragons, as the cooling I am using is so strong the machines will shutdown, even a 60watt heater will get over powered by the fans. So the insulating factor of the silicon sock is mandatory, and I keep using them. So I do hope they stay available and cheap a while longer, as I have to replace one about once a month on one machine or another.

This thing definitely works. Let's start with the packaging: look at the picture, it's nice haha.Ease of installation: this was as simple as swapping out the nozzle on the X1C, disconnected the old one and used the same fan, then installed the revo. Easy peasy took less than 5minPerformance: I'll say that it definitely outperforms stock nozzles. From the picture Included you can see that on the right is stock flow test and the left is revo. Revo actually finished the test while I had to actually cancel stock due to failure. In terms of quality printing from looks I would say the quality on the revo print started to fail about double past the stock.I'm excited to be able to try this with different nozzles and the quick swap as the biggest reason I got was that I could tell that the clips on the head board were starting to get loose so this will make it so I don't have to disconnect anything again. 10/10 would recommend to a friend.

STAY AWAY.Like some other reviews have stated this thing has leak at the heatbreak, and tightening stuff does NOT resolve it. its a waste of time and money. Find something else to go with.

Worked ok while it worked. Now the nozzles will no longer screw into the hotend. Waste of money. Look for another product, holes are not where they need to be to properly mount, failed 1 day after my return window and can no longer get any nozzle to screw into the hotend.

Is it overpriced for a simple heating unit, without even including aux fan? YesDoes it worth it? For the ability of swapping nozzle in 20 seconds with one hand, printing without worrying (too much) about nozzle wears because you can easily find cheap nozzle replacements, yes.

First let me say this hot end is one of the best on the market for its price range. It’s every actual meaningful upgrade you can do to a hot end packaged into a ready to install product, no searching around for parts trying to peace things together with random Chinese products and waiting months for things to come from Ali express. But sadly I cannot recommend this product to MOST of the ender 3 market.Pros.Best hot end under 100 bucks imo, no mods to the hot end are needed. Think of it as a “fully upgraded” e3d bi metal heat break, copper block, cart thermistor etc.Btw the built in Bowden tube connector is a feature not a con like some reviews said, it shortens the distance from the extruder to the hot end on direct drive.Beautiful construction, like stunning finish for a product in this price range it looks like it came from a custom CNC shop.ConsIt is NOT bolt on compatible with most* ender 3 (and ender 3 compatibles) printers. This hot end is SIGNIFICANTLY shorter than the stock ones used in all the ender 3 off the shelf printers, as well as most aftermarket ones (it’s to date the shortest one I have ever used on an ender) the problem is this causes it to create severe clearance issues with bl touch, fan shrouds, fans, part cooler fans etc being too long for the print head to reach the bed. This can easily be worked around for people who are “makers” modifying the entire assembly around it (shortening abl sensor mounts, lifting fans, custom fan mounts, custom fan shrouds etc) max so to speak of course BUT this product is sold as a direct replacement, it is Not. Adding to this the heat block itself is quite long front to back, meaning I’m almost all applications it interferes with the x carriage back plate and the sock is almost impossible to install without removing the hot end. Meaning a nozzle change requires you to 1 remove the whole fan shroud, 2 remove the hot end, 3 remove the sock and the nozzle, 5 reinstall the new nozzle and the sock, 6 reinstall the hot end, 7 reinstall the fan shroud. 7 step nozzle change on any ender printer if you use the sock. How convenient. Add onto this that the heat sink is not bolted to the heater block making it a huge risk of snapping the (proprietary) heat break.The fix for this is a set of longer screws and some washers to add clearance to the hot end from the carriage. Likely less than a cent worth of parts for the manufacture to include in the product DESIGNED to be compatible with the ender series printers. Now you have a new problem Your hot end fan will now have clearance issues. Again can be worked around but is just simply annoying for a upper end product in this industry being sold as compatible.Overall the problems with this product is that it does work and works amazingly, but it’s being sold as a compatible product for the ender 3 yet requires a complete overhaul of the x carriage accessories to make it work. This is fine if the product is sold this way but this is sold as a compatible product, a huge portion of the ender market is entry level users without any skill or knowledge about the printers, this advertising is just targeting them to sell them a product the do not need, and in many cases will not be able to use without spending significantly more money and time than is needed.
