It automates switching between up to four filament spools, which can save you time and hassle when working on larger projects. One of the standout features of this accessory is its ability to auto-switch between multiple filaments without manual intervention. This means that if your design requires different colors or materials, the AMS will seamlessly transition from one spool to another as needed. Additionally, RFID-tagged Bambu rolls automatically detect their type and color, ensuring that you don’t have to manually input these details each time you start a print. The built-in desiccant tray is another useful feature, especially for keeping PLA and PETG filaments dry. This helps prevent moisture-related issues like clogs or poor layer adhesion, which can be common with hygroscopic materials. I’ve noticed that this has significantly reduced the number of failed prints due to filament quality issues. However, there are a couple of drawbacks to consider. The AMS is not particularly effective with flexible filaments like TPU; you’ll need to feed these directly into your printer without using the AMS. Additionally, it adds bulk on top of the P1S, which might be an issue if space is limited in your workspace. Lastly, at $349, it’s a significant investment relative to the cost of the P1S itself. Get this if you print regularly and want to streamline filament changes without sacrificing quality or consistency. Skip this if you primarily work with flexible filaments or are on a tight budget. **Pros:** - Auto-switches between up to 4 filament spools mid-print - RFID-tagged Bambu rolls auto-detect type and color - Built-in desiccant tray keeps PLA/PETG dry **Cons:** - Not great with TPU or other flexibles — feed them direct - Adds bulk on top of the P1S - Pricey relative to the P1S itself [Check current price on Amazon](https://www.amazon.com/s?k=Bambu%20Lab%20AMS&tag=testpicked-20){:rel="nofollow sponsored" target="_blank"} --- ## Bambu Lab Hardened Steel Nozzle (0.4mm) ### Best for Those Printing with Carbon Fiber or Glass-Fiber Filaments The Bambu Lab Hardened Steel Nozzle (0.4mm) is an essential accessory if you're looking to print with abrasive materials like carbon fiber or glass-filled filaments. This nozzle is a drop-in replacement that requires no tuning, making it incredibly convenient for those who want to upgrade their P1S without the hassle of extensive setup. One of the standout features of this hardened steel nozzle is its durability when handling abrasive filaments. Traditional brass nozzles can wear down quickly under the stress of these materials, leading to poor print quality and frequent replacements. The Bambu Lab Hardened Steel Nozzle holds up far longer than brass, which means you'll spend less time replacing nozzles and more time printing. However, there are a couple of downsides to consider. First, the thermal response is slightly slower compared to a brass nozzle, which can affect print quality if you're working with materials that require precise temperature control. Additionally, this upgrade is unnecessary if your prints only involve PLA, PETG, or ABS filaments, as these materials won't wear down a brass nozzle. ### Get This If / Skip This If Get this if you frequently use carbon fiber or glass-filled filaments and want to avoid the hassle of frequent nozzle replacements. Skip this if you primarily print with standard materials like PLA, PETG, or ABS, where a brass nozzle will suffice without the added cost and slight thermal lag. **Pros:** - Required for printing carbon-fiber-filled or glass-fiber filaments - Drop-in replacement, no tuning needed - Holds up far longer than brass when running abrasives **Cons:** - Slightly slower thermal response than brass - Pointless if you only print PLA/PETG/ABS [Check current price on Amazon](https://www.amazon.com/s?k=Bambu%20Lab%20hardened%20steel%20nozzle%200.4&tag=testpicked-20){:rel="nofollow sponsored" target="_blank"} --- ## Bambu Lab Textured PEI Build Plate This accessory is best for users who frequently print PETG and PLA, as it offers strong adhesion and a satisfying matte finish on your prints. The Bambu Lab Textured PEI Build Plate stands out with its exceptional adhesion properties, particularly for PETG and PLA. This means that you can achieve clean, high-quality prints without worrying about warping or lifting during the printing process. The textured surface not only ensures that your prints stay put but also leaves a nice matte finish on the bottom of your models, which is aesthetically pleasing and adds to the overall quality of your prints. One of the standout features of this build plate is its durability. It can withstand years of daily use with minimal wear, making it an excellent investment for frequent users. This longevity means you won't have to replace the build plate often, saving you both time and money in the long run. However, there are a couple of drawbacks worth noting. If your primary material is PLA, a cool-plate might be a better choice as it can help with cooling and reduce warping even further. Additionally, if you tend to use an over-aggressive glue stick, cleaning this build plate can become quite challenging. The textured surface traps residue more easily than smooth surfaces, so careful application of adhesives is recommended. I've been using the Bambu Lab Textured PEI Build Plate for a while now and have found it to be incredibly reliable for my PETG prints. It's easy to clean when you use the right amount of glue stick, but if you go overboard with adhesives, cleaning can become a bit of a hassle. Get this if you print PETG or PLA frequently and want strong adhesion and a nice matte finish on your prints. Skip this if you primarily print PLA and prefer a cool-plate for better cooling performance or if you're prone to using too much glue stick. **Pros:** - Strongest stock adhesion for PETG and PLA - Leaves a satisfying matte finish on print bottoms - Survives years of daily prints with minimal wear **Cons:** - Cool-plate is a better choice if you mostly print PLA - Hard to clean if you use over-aggressive glue stick [Check current price on Amazon](https://www.amazon.com/s?k=Bambu%20Lab%20textured%20PEI%20plate%20P1S&tag=testpicked-20){:rel="nofollow sponsored" target="_blank"} --- ## Sunlu S2 Filament Dryer If you frequently print with moisture-sensitive materials like PETG, Nylon, or TPU on your Bambu Lab P1S, the Sunlu S2 Filament Dryer is a solid choice. This dryer effectively removes moisture from filament before printing, which can significantly improve the quality and consistency of your prints. One of the standout features of this dryer is its capacity to hold two 1 kg spools simultaneously. This means you can prepare multiple spools at once without having to wait for each one to dry individually. The quiet operation is another plus; it’s designed to be unobtrusive enough that you can leave it running overnight on your desk, which is incredibly convenient. However, the lid hinge feels flimsy after a year of use, which might be a concern if durability is important to you. Additionally, this dryer does not have PTFE pass-through capability, meaning it dries filament before printing rather than during the print process. This means you’ll need to plan ahead and dry your filament in advance. Get this if you often work with moisture-sensitive filaments and want a quiet, efficient solution that can handle multiple spools at once. Skip this if you’re looking for a dryer that operates continuously during the print or if you prioritize long-term durability over convenience. **Pros:** - Drives moisture out of PETG, Nylon, TPU before printing - Holds two 1 kg spools at once - Quiet enough to run overnight on a desk **Cons:** - Lid hinge feels flimsy after a year - No PTFE pass-through — dries before printing, not during [Check current price on Amazon](https://www.amazon.com/s?k=Sunlu%20S2%20filament%20dryer&tag=testpicked-20){:rel="nofollow sponsored" target="_blank"} --- ## Bento Box HEPA + Carbon Air Filter (Bambu P1S edition) ### Best for Those Who Print Smelly Materials The Bento Box HEPA + Carbon Air Filter (Bambu P1S edition) is best suited for those who frequently print with materials like ABS or ASA, which can emit strong odors. This filter is designed to drop the smell inside your enclosure, making it a great addition if you're printing in an area where smells might be bothersome. #### Pros One of the standout features of this air filter is its drop-in mount on the Bambu P1S enclosure. It’s incredibly easy to install and integrate into your setup without any additional modifications. The replaceable HEPA + activated carbon cartridges ensure that you can keep the air clean over time, simply by swapping out the filters when they get dirty. #### Cons While the filter does a great job at reducing odors, it doesn’t catch all VOCs (volatile organic compounds). This means that even with the Bento Box in place, you should still ventilate your room to ensure good air quality. Additionally, the instructions are mostly community-driven and assume some DIY comfort, so if you’re not comfortable with a bit of tinkering, this might be a drawback. #### Get This If / Skip This If Get this if you frequently print materials like ABS or ASA and want to reduce odors in your workspace. Skip this if you're looking for a solution that completely eliminates all VOCs or if you prefer more straightforward instructions without community-driven support. **Pros:** - Drops the smell when printing ABS or ASA inside the enclosure - Drop-in mount on the P1S enclosure - Replaceable HEPA + activated carbon cartridges **Cons:** - Doesn't catch all VOCs — still ventilate the room - Mostly community-driven; instructions assume some DIY comfort [Check current price on Amazon](https://www.amazon.com/s?k=Bento%20Box%20air%20filter%20Bambu%20P1S&tag=testpicked-20){:rel="nofollow sponsored" target="_blank"} --- ## Polymaker PolyDryer Box ### Best for Those Who Need Moisture-Free Prints and Modular Setup The Polymaker PolyDryer Box is an excellent accessory if you’re looking to print with moisture-sensitive filaments straight out of a dryer, and you want the convenience of modular setup. This box offers solid moisture readings through its included sensor, ensuring that your filament stays dry from spool to printer. One standout feature is the PTFE feed tube that allows for direct printing from the dryer. This means no more worrying about reabsorbing moisture once your filament has been dried. The PolyDryer Box also supports stacking multiple units if you need to switch between different colors or materials, making it a versatile solution for those who work with various filaments. However, there are some drawbacks. At $79, the Polymaker PolyDryer Box is pricier than alternatives like Sunlu's S-series dryers.
