The 22IDEX is designed to be a turnkey solution with built-in filament drying capabilities. This allows you to dry and maintain your filament while printing. The machine includes two dedicated spool holders inside the chamber, designed to fit most standard 1kg spools.
However, if you wish to use larger spools—such as 2kg or bigger—you have two primary solutions:
Below, we describe both approaches in detail. The second solution also includes step-by-step instructions on bypassing (or removing) the filament sensor if needed and installing a printed adapter with T-nuts and screws.
If you are printing shorter parts and have space on the chamber floor, you can place a larger spool inside the heated chamber:
This method keeps your larger spool inside the chamber, allowing you to maintain a heated, low-humidity environment around the filament.
If you are printing tall parts or otherwise need the interior space, you may want to place the large spool outside the 22IDEX and reroute your filament feed tubes. Follow these steps:
By default, the 22IDEX uses a filament sensor inside the chamber (for v2) or on the back panel near the main board (for v3). When moving the filament feed outside the machine, you can:
Locate the PTFE Fitting
Detach the PTFE Tube
Pull the Tube From the Machine (If Reusing the Same Tube)
Route Over the Top Cable Chain
Use the Rectangular Cutout
Print and Install the PTFE Tube Adapter
Place the Spool Externally
Feed Filament Through the PTFE Tube
Secure and Protect the Spool
By following these steps, you can efficiently use both standard and larger spools with your 22IDEX printer. The built-in drying capabilities and versatile spool holder design ensure that your filament remains dry and ready for high-quality prints—even if you opt to bypass the internal filament sensor to accommodate very large external spools.
