Install the 2.20 Hotend on your Bambu Lab P2S

More control, maximum stability, and zero drama with flexible filaments.

1. Introduction

This isn’t just a new nozzle. It’s the Filaflex 2.20 System: a larger internal diameter designed to prevent flexible filaments from compressing and losing drive. In this guide, we will transform your Bambu Lab P2S to print flexibles with industrial stability while maintaining 100% compatibility with standard 1.75mm rigid filaments.

3. Step by Step Hardware Installation

Follow this sequence to integrate the Filaflex 2.20 system into your P2S. Each phase is designed to facilitate assembly and ensure flow precision. We will start by accessing the print head, followed by the specific adjustments that unlock industrial-grade flexible printing. Take your time, follow the icons, and transform your machine into a high-performance flexible powerhouse.

Step 1: Unload & Power Down

Action 1: Unload the filament from the menu.

Image Image

Action 2: Manually lower the print bed to create enough space to work comfortably.

Image Image

Action 3: Turn off the power switch at the back and unplug the power cord.

Image
Step 2: Access

Remove the glass: Take off the top glass cover to work comfortably from above.

Image
Step 3: Release the Feeding PTFE

Press the connector trigger to remove the Teflon feeding tube from the extruder.

Image
Step 4: Remove Front Hotend Cover and Disconnect Fan

The front cover is magnetic; remove it carefully.

🔴 SAFETY: The part cooling fan is attached to the cover. Disconnect its terminal gently, avoiding pulling directly on the wires.

Image Image
Step 5: Hotend Removal

🔴 SAFETY: Ensure the hotend is completely cool before touching it.

1. Remove the silicone sock.

2. Open the latches/screws holding the hotend in place.

Image

3.Extract it from the machine.

Image
Step 6: Enlarge the Filament Channel

This is the only additional procedure that enables simultaneous hybrid compatibility (1.75 mm and 2.20 mm).

Prepare the tool: Mount the drill bit in the included handle, leaving it as extended as possible for better access.

Image Image

Bottom access: Insert the drill bit vertically from below. Rotate gently; the drill will advance without the need for brute force. The bit will make its own way; rotate twice and reverse the rotation to move forward.

Image

The Limit: Stop as soon as you feel the drill bit reach the extruder gears.

Image

Top access: Repeat the operation from the top, rotating gently until you see movement in the side gears.

Image Image

🟢 INFO: By doing this, we gain a few microns of space so the 2.20 filament passes easily, without affecting precision when printing with 1.75 mm.

🔵 PRO TIP: You can store the tool away; you won't need it again.

🔴 SAFETY: Any physical modification may affect the manufacturer's official warranty; proceed at your own responsibility.

Step 7: Extruder Channel Cleaning

Blow through the channel or use a blower to remove any shavings or plastic residue from inside the channel.

Image

Clean the shavings from the printer base as well.

Image
Step 8: Install the Recreus 2.20 Hotend

Open your new Recreus 2.20 Hotend and place the new Recreus hotend in position and secure it firmly.

Image

Replace the protective silicone sock.

Image
Step 9: Reassembly

Connection: Reattach the front cover, connecting the fan to its corresponding port.

Image Image
Step 10: PTFE Tube

Insert a short length of PTFE tube into the top entry of the extruder.

Image
Step 11: Load & Purge

🟢 INFO: In this case and with flexibles, it is recommended to load the material manually. Let's see how it's done.

Turn on your 3D printer to start the final configuration process.

Image

Moisture management: To optimize printing, you can use a side dryer for the filament spool. Find the bracket and further instructions below.

Image Image

When working with the 2.20 system, we recommend introducing the filament manually initially.

Image

From the control tab of your Bambu Lab, heat the nozzle to 245°C.

Image

Activate the extrusion controls (clicking the down arrow) while pushing gently to perform a full purge and clear any residue from the channel.

Image

🔵 PRO TIP: If the purged material flows in a steady, continuous thread, your installation is 90% successful!.
