Top 10 Must-Have Accessories for Your Bambu Lab P1S

If you just unboxed your Bambu Lab P1S, you probably feel like you have the best printer on the market. And you probably do. But even the best machines benefit from a few smart add-ons. These accessories aren’t just ‘nice to have’ extras; they are specific tools that solve real-world printing headaches, boost reliability, or unlock new materials. We’ve compiled a list of the must-haves to make your P1S setup truly professional.

Why Accessories Matter for the P1S

The P1S is a powerhouse, but its performance is only as good as its setup. Accessories generally fall into three categories: Material Handling (making it easier to print weird stuff), Maintenance/Upgrades (keeping it running perfectly), and Utility (making the whole process smoother). Knowing which category you need to upgrade first is key.

The Essential Upgrades

Here are the accessories we recommend looking at first to maximize your P1S’s potential.

1. Extra Build Plate Surface Options

While the standard build plate is great, different materials demand different adhesion strategies. If you plan on printing a lot of flexible filaments or high-temp resins, having alternative, specialized build surfaces is a game-changer. This isn’t about having more plates; it’s about having the right plate for the job.

2. Specialized Filament Dry Boxes

Moisture is the silent killer of prints. Even if your filament spool seems fine, humidity in the air will degrade PLA and PETG over time, leading to stringing, popping, and poor layer adhesion. A dedicated, reliable dry box that keeps your spools dry and organized is non-negotiable for serious users.

3. Tooling and Maintenance Kits

Regular maintenance keeps the P1S running like new. Look for kits that address common wear points—things like nozzle cleaning systems or precise bed leveling tools. These aren’t flashy, but they directly impact print quality consistency over hundreds of hours of use.

Versatility Boosters

These items let you print things you might not have thought you could print.

4. Direct Drive Extruder Upgrades (If Applicable)

Depending on your specific workflow, an upgrade to the extruder system can give you better control, especially when dealing with very flexible or highly abrasive materials. This is a deep dive, but if your primary use case involves advanced materials, it’s worth investigating.

5. Filament Guide/Spool Holders

Nothing slows down the workflow more than wrestling with spools that are too close together or falling off the build surface. Good, sturdy spool management keeps your station clean and your prints flowing without interruption.

Decision Guidance: What Should You Buy First?

If you are a beginner, focus on the Filament Dry Box and Extra Build Plates. These solve the most common, immediate failure points. If you are an experienced user who prints daily, prioritize Tooling and Maintenance Kits to keep your machine dialed in.

Ultimately, the best accessory is the one that solves the problem you are currently having. Don’t buy things because they exist; buy them because your current process breaks without them.
