Bambu P1S Hotend Upgrade: Design Comparison & Key Differences
All three aftermarket hotends are engineered for Bambu P1S (and compatible with Bambu X1 series) printers—making them top choices for Bambu P1S Hotend upgrade enthusiasts—and are popular mods for other models too. However, their design philosophies diverge sharply from the stock Bambu P1S hotend—and each other. Below is a detailed look at how each hotend stacks up in terms of engineering and functionality for your Bambu P1S Hotend upgrade.
BIQU Panda Revo: Convenience with Compromises for Bambu P1S Hotend Upgrade
The BIQU Panda Revo stands out in this Bambu P1S Hotend upgrade comparison for its E3D Revo nozzle compatibility, which enables tool-free, quick nozzle swaps—a major plus for Bambu P1S users who frequently change nozzle sizes. However, this convenience comes with notable trade-offs that matter for your Bambu P1S Hotend upgrade:
- Its melt zone is 4mm shorter (a 17% reduction) than the stock Bambu P1S hotend. Since a longer melt zone directly boosts flow rate, this is a significant limitation for high-flow printing in a Bambu P1S Hotend upgrade.
- The detachable nozzle and heat block create micro-gaps, leading to poor heat transfer that further restricts flow potential for Bambu P1S users.
- Unlike the stock Bambu P1S and E3D hotends (which bend or break on impact to protect the printer’s motion system), the Panda Revo has a rigid build. This lack of impact absorption is a key consideration for new 3D printing users pursuing a Bambu P1S Hotend upgrade, as it raises the risk of printer damage from collisions.
Phaetus Conch+: Maximizing Melt Zone Length for Bambu P1S Hotend Upgrade
Phaetus takes the opposite approach in this Bambu P1S Hotend upgrade comparison, designing the Conch+ around an extended melt zone that measures 30mm—25% longer than the stock Bambu P1S hotend. To prevent heat from spreading to the heatsink (a critical factor for Bambu P1S Hotend upgrade reliability), it features a thermal insulation ring, which proved reliable even in a 37°C print chamber (22°C ambient temperature).
Testing revealed only one downside: subpar print cooling performance at higher temperatures for Bambu P1S prints, though clogging was never an issue. Like the Panda Revo, the Conch+ has a rigid structure and lacks the stock Bambu P1S hotend’s impact protection—something to note for your Bambu P1S Hotend upgrade decision.
E3D High-Flow ObXidian: Performance Meets Safety for Bambu P1S Hotend Upgrade
The E3D HF ObXidian looks nearly identical to the stock Bambu P1S hotend but packs a genuine CHT (Cyclops Hot Tip) insert inside—its secret weapon for high-flow performance in a Bambu P1S Hotend upgrade. In this Bambu P1S Hotend upgrade comparison, it’s the only aftermarket option that retains the stock Bambu P1S hotend’s impact-resistant, breakable design, which bends or breaks on impact to safeguard the printer’s motion system. This balance of power and safety makes it a standout choice for many Bambu P1S users seeking a reliable Bambu P1S Hotend upgrade.
Bambu P1S Hotend Upgrade: Layer Adhesion Test Results
To conduct a fair Bambu P1S Hotend upgrade comparison, layer adhesion testing was done with Bambu Basic black PLA (color impacts adhesion, so purple PLA from prior tests was replaced) and a revised test print design—smaller but twice as thick to mirror real-world Bambu P1S printing conditions. All hotends used 0.4mm nozzles, with performance measured by the force required to break samples printed at increasing flow rates and speeds—critical metrics for evaluating a Bambu P1S Hotend upgrade.
Stock Bambu P1S Hotend: Baseline Performance for Upgrade Evaluation
The stock Bambu P1S hotend set a solid baseline in this Bambu P1S Hotend upgrade comparison, performing well up to a 14 mm³/s flow rate with only a 9% drop in adhesion strength. Beyond this point, performance declined rapidly: at 21 mm³/s, layer adhesion plummeted by a massive 40%. It’s sufficient for casual, low-speed Bambu P1S printing but struggles with high-flow demands—making it a clear candidate for a Bambu P1S Hotend upgrade for power users.
E3D HF ObXidian: Top-Tier Performance for Bambu P1S Hotend Upgrade
The E3D HF ObXidian dominated the layer adhesion tests in this Bambu P1S Hotend upgrade comparison, showing no loss in adhesion strength even at a printing speed of 300mm/s (a speed many Bambu P1S users aim for with an upgrade). The CHT insert’s superior filament-melting capability outclasses the stock Bambu P1S hotend by a wide margin, making it the clear winner for high-speed, high-flow printing in a Bambu P1S Hotend upgrade.
BIQU Panda Revo: Underwhelming Results for Bambu P1S Hotend Upgrade
The Panda Revo disappointed in this Bambu P1S Hotend upgrade comparison, even with the Revo High Flow ObXidian nozzle:
- It only outperformed the stock Bambu P1S hotend at extremely high flow rates and speeds, and even then, adhesion strength dropped by 23%—a lackluster result for a Bambu P1S Hotend upgrade.
- The included brass high-flow nozzle is a misstep: it offers no meaningful melting performance boost and is prone to wear—a poor fit for Bambu P1S printers, which constantly rub and probe the nozzle tip.
- The regular flow Revo ObXidian nozzle fared even worse, performing well only up to 7 mm³/s—a stark contrast to the high-flow version and a letdown for Bambu P1S users seeking an upgrade.
Phaetus Conch+: Surprising Overachiever for Bambu P1S Hotend Upgrade
The Phaetus Conch+ delivered a standout performance in this Bambu P1S Hotend upgrade comparison, with a 50% improvement in layer adhesion strength at 21 mm³/s compared to the stock Bambu P1S hotend. This impressive result is especially notable because it doesn’t rely on a CHT-style flow-boosting design—its extended melt zone alone drives the enhanced flow and adhesion, with no reliability issues during Bambu P1S testing. For budget-conscious Bambu P1S users, this makes it a compelling Bambu P1S Hotend upgrade option.

Final Recommendations for Bambu P1S Hotend Upgrade
Based on this Bambu P1S Hotend upgrade comparison, here’s how to choose the right hotend for your Bambu P1S printer:
- For unbeatable performance: The E3D HF ObXidian is the top choice for Bambu P1S users who prioritize high-speed printing and maximum layer adhesion in their Bambu P1S Hotend upgrade. While it’s the priciest aftermarket option, its wear resistance, impact protection, and flawless test performance justify the cost for power users and those who demand the best from their Bambu P1S.
- For budget upgrades: The Phaetus Conch ($27) offers the best value for Bambu P1S owners looking to improve on the stock hotend without overspending on a Bambu P1S Hotend upgrade. The Conch+ ($43) is the pick for those who print with abrasive filaments regularly—delivering high performance at a mid-range price point. And you can enjoy a special price in Call3D through its direct delivery service.
- For nozzle flexibility: The BIQU Panda Revo is only worth considering if you already own Revo nozzles or need to swap nozzles frequently on your Bambu P1S. Its high price and mediocre performance make it a niche choice for Bambu P1S Hotend upgrade otherwise.
In the end, the best hotend for your Bambu P1S depends on your priorities—whether it’s speed, budget, nozzle versatility, or abrasive filament compatibility. ThisBambu P1S Hotend upgrade comparison should help you align your choice with your Bambu P1S printing workflow and needs!
