The Bambu Lab AMS Lite (Automatic Material System Lite) is the strongest overall upgrade for Bambu owners who regularly print in multiple colors or materials. It belongs on an under-$100 list only when the purchase total fits that budget. For most single-color PLA and PETG users, the SUNLU dryer is the more broadly useful place to start.

Start With the Problem You Actually Have
Accessories are most useful after the printer has a stable foundation. Clean the build surface, handle basic calibration, and address obvious mechanical problems before adding more gear. A camera will not improve a poor first layer. A dryer will not correct a damaged nozzle. An automatic material system will not make a single-color print better.
Once the printer is working normally, look for the annoyance that repeats most often.
A filament dryer makes sense when PLA or PETG has been left open between jobs and material handling has become inconsistent. A camera is useful when prints run while you are in another room, at work, or asleep. The AMS Lite is for Bambu owners who make multi-color or multi-material printing part of their regular workflow rather than an occasional experiment.
The silicone sock tool is the smallest and most specialized pick here. It is not exciting, but regular hotend cleanup can be easier when plastic buildup around the nozzle has become a recurring chore.
1. Bambu Lab AMS Lite: Best Overall for Bambu Multi-Color Printing
Make repeat color changes less tedious
The Bambu Lab AMS Lite is an automatic material system for Bambu owners who want cleaner, more repeatable multi-color and multi-material prints. Its appeal is straightforward: it reduces the repeated handling that comes with changing filament during projects that use several colors or materials.
That makes it especially useful for color-coded organizers, signs, labels, toys, decorative models, and other projects where the same kind of filament switching happens again and again. Instead of treating every color change as a separate interruption, the AMS Lite turns it into part of the printing workflow.
This is the most transformative accessory in the group when it matches the way you print. It changes the workflow itself rather than simply adding another maintenance step.
Who should choose it
Choose the AMS Lite when multi-color printing is already a regular part of your Bambu setup and the purchase stays within your under-$100 budget. It is also a strong fit for makers who print batches of similar projects with color-coded details.
Skip it when you mostly print one-color parts. A single-color PLA workflow gains little from an automatic material system, while a dryer or camera can help across nearly every print. It is also not a universal feeder for every FDM printer, so non-Bambu owners should spend their budget elsewhere.
2. SUNLU Filament Dryer Box with Temperature Display (S2): Best Value for PLA and PETG
Put filament care before endless tuning
The SUNLU Filament Dryer Box with Temperature Display (S2) is the most broadly useful pick for PLA and PETG users who want a simpler way to manage filament before printing. It adds a dedicated drying step to the routine, which is often more helpful than changing several slicer settings at once.
A dryer is especially useful for open spools that sit between projects. Instead of treating every inconsistent result as a reason to adjust retraction, temperature, or cooling, you can begin with the material itself. That keeps troubleshooting simpler and prevents a pile of slicer changes from obscuring the real issue.
The temperature display is a practical touch because it keeps the dryer’s purpose visible: this is a material-prep accessory, not another printer upgrade that needs constant tinkering.
Who should choose it
Choose the SUNLU S2 if PLA and PETG are your usual materials and you want to lower the chance of filament-related trouble without changing your printer hardware or learning a new software workflow.
Skip it when the printer has an obvious mechanical or first-layer problem. If the bed needs cleaning, the nozzle is worn, or calibration is off, handle that work first. A dryer supports good material handling; it does not replace printer maintenance.
3. Bambu Lab PETG Filament (1 kg): Best for Functional Parts
Use PETG when the part has a job to do
The Bambu Lab PETG Filament (1 kg) is the right pick when the material itself is the missing piece. If you are printing brackets, clips, storage parts, holders, or everyday workshop fixtures, moving from a display-focused spool to PETG can be more meaningful than buying another accessory.
A single, familiar PETG spool also keeps your workflow more consistent. When you are trying to refine a functional print, it helps to avoid changing material and print settings at the same time. Start with a PETG profile intended for your printer, then make small changes only when the part calls for them.
This is not a printer repair or a shortcut around setup. It is simply the right material category for projects where a functional part is the goal.
Who should choose it
Choose Bambu Lab PETG when you use a Bambu printer and regularly make utility parts such as brackets, clips, enclosures, or organizers.
Skip it when your printer is mainly used for low-stress display models, decorative figures, terrain, and prototypes that are already well served by PLA. In that case, a dryer or camera usually has a wider effect on the rest of your print routine.
4. FLSUN Wi-Fi Camera for 3D Printer Monitoring: Best for Unattended Prints
See trouble while there is still time to stop the job
The FLSUN Wi-Fi Camera is a focused accessory for people who cannot stay beside the printer for every long job. It is designed for remote monitoring and timelapse capture, making it easier to keep an eye on the print and spot visible issues such as adhesion trouble or layer shifts.
Its value is timing. A print that starts going wrong in the first layers can otherwise continue for hours before anyone notices. A camera gives you a chance to see that the job needs attention rather than discovering the problem after a large amount of filament and printer time has already been spent.
For practical monitoring, aim the camera at the print area rather than treating it as a timelapse-only accessory. The first layer, nozzle path, and early part growth are usually the most useful things to see.
Who should choose it
Choose the FLSUN camera for overnight jobs, long projects, or a printer located in a garage, workshop, office, or separate room. It is particularly helpful when you want a simple visual check without building a more involved monitoring setup.
Skip it when you expect a camera to repair the problem it sees. It provides visibility, not automatic recovery. If adhesion or motion problems are common, address those directly before relying on remote monitoring.
5. Generic Silicone Sock Tool for Nozzle and Hotend Cleaning: Best Small Maintenance Upgrade
Keep the hotend area easier to manage
A generic silicone sock tool for nozzle and hotend cleaning is a modest accessory with a specific role: helping keep the area around the nozzle and hotend cleaner. For printers that collect hardened plastic around the heater block, that can make regular maintenance less of a chore.
This is particularly relevant for PETG users and anyone who frequently deals with ooze around the nozzle during heating, purging, or material changes. Keeping that area tidy helps prevent loose debris from becoming part of the print environment.
It is the least dramatic upgrade on this list, but it can be a useful addition once the printer is already calibrated and working properly. A clean hotend area is easier to inspect and maintain than one covered in old plastic.
Who should choose it
Choose the silicone sock tool when external hotend buildup is the recurring issue and you want a simple maintenance accessory for the nozzle area.
Skip it when the problem is inside the extrusion system. An internal clog, worn nozzle, poor first-layer setup, or filament-grinding issue needs direct diagnosis and repair rather than an external cleaning accessory.
A Practical Order for Spending Your Budget
A small accessory budget goes further when you spend it in the same order that problems tend to show up.
- Handle basic cleaning, calibration, and obvious maintenance first.
- Add a filament dryer when open PLA or PETG is part of the problem.
- Add a camera when unattended jobs are wasting time and material.
- Add PETG when functional parts are becoming a regular part of your printing.
- Add the AMS Lite when Bambu multi-color or multi-material projects are frequent enough to justify it.
- Add a silicone sock tool when hotend cleanup has become a regular task.
That order keeps the printer bench from filling up with accessories that do not address the actual source of the frustration.
What Not to Buy First
Avoid buying an accessory simply because it looks like an upgrade. A second display, decorative lighting, or a broad tool bundle may be useful later, but they do not directly address common causes of wasted prints and interrupted jobs.
Likewise, do not treat every print issue as a reason to change hardware. Start with the basics: a clean build surface, a stable first layer, sensible material handling, and a nozzle area free from accumulated plastic. Once those habits are in place, the picks above solve much more specific problems.
Before You Buy
Keep the under-$100 limit honest
The AMS Lite is the one product here that should be treated carefully in a strict under-$100 budget. It is the top workflow upgrade for the right Bambu owner, but only when its purchase total stays within the cap.
The other picks are easier to use as targeted purchases: a dryer for material care, PETG for a functional project, a camera for monitoring, or a cleaning accessory for hotend upkeep.
Buy for the projects you print most often
Print mostly PLA figures and display models? A camera or dryer is likely to affect more of your jobs than PETG or an automatic material system.
Print brackets, clips, and holders? PETG is a more useful upgrade than a cosmetic accessory.
Print signs, organizers, labels, and multi-color models on a Bambu printer? The AMS Lite can save the most repetitive manual work.
Run long prints while away from the machine? Put the camera near the top of the list.
Keep accessories from replacing maintenance
Every accessory works better when the printer is already looked after. Clean the build surface before longer jobs. Watch the first layer before leaving the machine unattended. Keep open filament organized. Remove loose plastic around the nozzle before it becomes a larger cleanup job.
These habits are simple, but they make the dryer, camera, PETG, AMS Lite, and silicone sock tool more useful.
Final Recommendations
For Bambu owners who regularly make multi-color or multi-material prints, the Bambu Lab AMS Lite is the best overall choice when it fits within the $100 budget. It removes repeated filament handling and makes that style of printing easier to repeat.
For the broadest upgrade across ordinary PLA and PETG printing, choose the SUNLU Filament Dryer Box with Temperature Display (S2). It is a practical addition for anyone who keeps spools open between projects and wants a more consistent material-prep routine.
Choose the FLSUN Wi-Fi camera for remote checks and long unattended jobs. Choose Bambu Lab PETG when brackets, clips, and utility parts are becoming part of your regular printing. Choose the silicone sock tool when hotend cleanup is the small problem that keeps coming back.
FAQ
Is a filament dryer a better first purchase than a new nozzle?
Choose a dryer when your goal is better PLA and PETG material handling, especially for spools that have been stored open between print jobs. A nozzle replacement is a separate maintenance task for a nozzle that is worn, damaged, or clogged.
Is the Bambu Lab AMS Lite for every 3D printer?
No. The AMS Lite is intended for Bambu printer workflows rather than universal use. It is the right choice for Bambu owners who print in multiple colors or materials regularly, not for every FDM printer owner.
Can a Wi-Fi camera stop a failed print?
A Wi-Fi camera helps you see a problem while the print is running. It is useful for spotting visible trouble early, but it does not correct adhesion, motion, or extrusion problems on its own.
Is PETG a good choice for brackets and clips?
Yes. The Bambu Lab PETG spool is aimed at functional parts such as brackets, clips, and everyday utility prints. Use it when the project calls for PETG rather than treating it as a replacement for printer maintenance or calibration.
Does a silicone sock fix an internal nozzle clog?
No. A silicone sock tool is for external nozzle and hotend cleanup. An internal clog or worn nozzle needs separate cleaning, diagnosis, or replacement.
