P1S Nozzle Upgrade: Choose the Right Option for Your 3D Printing Needs

In the world of 3D printing, the hotend serves as the critical final gateway for filament—and for Bambu Lab P1S users, a P1S nozzle upgrade can drastically elevate print consistency, durability, and versatility. Choosing the right P1S nozzle upgrade is a balance of cost, reliability, and compatibility with your printing materials. Drawing on experience working with hobbyists, engineers, and professional users, we break down the real-world differences between three top-tier P1S nozzle upgrade options: Bambu Lab Original (OEM) Nozzles, Call3D Modular Nozzles, and Phaetus High-Performance Hotends—all backed by concrete data and tailored for P1S compatibility.

For P1S users seeking a straightforward, cost-effective P1S nozzle upgrade that aligns with their printer’s original design, Bambu Lab’s official nozzles are the natural starting point. Their biggest advantage Includes

• Seamless compatibility with the P1S ecosystem, 
• Paired with an affordable price tag that keeps the total cost of ownership low for general use. Additionally
• Wiki & Community ensures quick replacements for faulty units.

However, there’s a trade-off to consider with this P1S nozzle upgrade. Due to production across multiple OEM factories, batch consistency can vary. Reddit feedback and internal testing show a failure rate ranging from 2%-5%—meaning you might get several flawless nozzles for your P1S, followed by one prone to clogging or premature failure. For the vast majority of P1S users printing standard materials (PLA, PETG, ABS), this isn’t a deal-breaker. The minor inconvenience is offset by the low cost and seamless P1S integration, making it a solid P1S nozzle upgrade for hobbyists, casual users, and non-critical prototyping.

At Call3D, we designed our modular nozzles as a purpose-built P1S nozzle upgrade to address the consistency gaps of stock options. Priced closely to Bambu Lab originals, this P1S-compatible upgrade stands out with two key advantages:

• Rigorous quality control .We source components from one rigorously vetted suppliers and subject every single P1S-compatible nozzle to 100% flow rate and air-tightness testing. The result? A P1S nozzle upgrade with a tested outgoing defect rate of under 1%—far more reliable than stock alternatives for consistent P1S performance.
• A modular design.The modular design is a game-changer for P1S users: instead of replacing the entire hotend when parts wear, you can swap just the nozzle or heatbreak throat. This not only reduces long-term replacement costs by up to 60% but also cuts down on e-waste—perfect for P1S users who value sustainability and easy maintenance.

For over 90% of P1S applications with standard materials, our Call3D hardened steel nozzles excel. In lab tests simulating real-world P1S use (500 hours of continuous printing with PLA/PETG), nozzle orifice wear was less than 10 microns—with no noticeable drop in print quality. If you’re a P1S user who values consistency, low maintenance, and cost efficiency for standard or mildly abrasive materials, this is the ideal P1S nozzle upgrade.

For P1S users pushing their printer to handle carbon fiber, fiberglass, or other filled composites, a Phaetus hotend is the ultimate P1S nozzle upgrade. My experience with Phaetus (dating back to my time at Raise3D) confirms their reputation for leading-edge, P1S-compatible solutions—why we feature them as a top-tier P1S upgrade option.

While Bambu Lab and Call3D’s hardened steel nozzles work for standard P1S prints, they wear quickly when printing materials with 10%+ carbon fiber. Phaetus solves this with advanced materials tailored for abrasive use: Silicon Carbide (SC) and EndCoat Harden Steel—both fully compatible with the P1S. Here’s how they perform as a P1S nozzle upgrade, backed by lab data.

Silicon Carbide (SiC): Extremely hard but brittle, this P1S-compatible nozzle delivers binary performance—either it works flawlessly or shatters upon impact. Until that point, wear is virtually non-existent, ensuring consistent P1S print quality over time. In tests with 20% carbon fiber-filled PA (a common abrasive material for P1S users), the SC nozzle’s orifice change remained within ±3 microns (measurement error) after 1,000+ hours of printing—perfect for P1S users needing unwavering precision for long print cycles.
