It is used to maintain the alignment and stability of the ankle joint and control the ankle’s rotation. Articulated AFOs are printed on the **Galileo O&P machine.** ### How to Order 1. Before ordering this product, clinician preferences must be established with the Protosthetics design team. If you have not set up or want to update your clinician preferences, please schedule a meeting with your design lead by emailing [success@protosthetics.com](mailto:success@protosthetics.com). 2. Log into [FabOne](https://proto.fab.one/), and click “Order” under the Articulated AFO section. 3. Attach a scan of the limb, cast, or plaster positive. 4. Proceed to the order form to fill out the requested details. ![](https://www.help.protosthetics.com/hs-fs/hubfs/image-png-Jul-16-2026-04-04-56-8314-PM.png?width=378&height=258&name=image-png-Jul-16-2026-04-04-56-8314-PM.png) ### Design Options on the Order Form | AFO Types - **Standard articulated AFO:** Full height for greater control of the limb, printed at 3.5 mm thick. - **Short articulated AFO:** Richie-style short shank used to control milder pathologies, printed at 3.5 mm thick. - **Pediatric articulated AFO:** Thinner 2.5 mm print for pediatric cases. [See dedicated product page for full details.](https://www.help.protosthetics.com/galileo/pediatric-afo?hsLang=en) | Material - **PC Blend:** our standard material offering. - **Nylon (Beta):** material option in beta testing with more flexibility. | | --- | --- | | Cast Corrections - **None** - **Correct to neutral in frontal plane**: the shank and foot will be vertically aligned in the frontal plane to eliminate pronation or supination in the scan. - **Correct to 90 degrees in sagittal plane**: Correct the scan to an ankle angle of 90 degrees in the sagittal plane to eliminate dorsiflexion or plantar flexion in the scan. | Design Additions - **Add plantar flexion stop:** Limits range of motion of the ankle to eliminate plantar flexion by adding a plastic buildup (stop) posterior to the ankle on the footplate and shank. - **Flare proximal trimline:** Flare the trimline at the proximal edge of the shank piece to reduce pressure on calf muscle and enable easier doffing. | | Space for Footplate Padding - The selected amount of space is added to the footplate on the sole of the foot, not along the medial or lateral footplate surfaces. - Space options are: None, 1/8”, 3/16”, or 1/4” | Joint Options **Choose from the following joints:** - Tamarack 740 L - Tamarack 740 M - Tamarack 742 L Dorsi-Assist - Tamarack 742 M Dorsi-Assist - Tamarack 740 P - Tamarack 742 P Dorsi-Assist | | Heel Posting - **None:** no flat surface added - **Neutral:** flat surface added beneath the heel - **Medial, Lateral:** flat surface added distally beneath the heel and shifted in the selected medial or lateral direction | Reliefs A standard depth of 2mm will be applied to the relief location. Please specify in additional information if you would like to change this value or relieve any other locations. - Medial or lateral malleoli - Navicular - Base of the 5th met. | ### **Req**uired Measurements We will ask you for the following measurements in the order form (\*required measurements): ![measurements 1-4](https://www.help.protosthetics.com/hs-fs/hubfs/measurements%201-4.png?width=259&height=219&name=measurements%201-4.png) 1.

The wall thickness is 3.5 mm. After printing, you can continue fabrication: #### Grinding Break off support material on the heel of the footplate. Use 100-150 grit sandpaper to remove any residual support material. Use 400-600 grit sandpaper to smooth the trimlines. Use Tycro or silicone polishing cones to perfect the finish. #### Removing Stringing ![File (1)](https://www.help.protosthetics.com/hs-fs/hubfs/File%20(1).jpg?width=239&height=319&name=File%20(1).jpg) If you see stringing like the photo above on your prints, it means your filament has likely taken on some moisture.  1. Make sure your filament is in the dehydrator and your dehydrator is on to remove moisture going forward. 2. To remove the stringing quickly, take a heat gun or blowtorch to the strings quickly to burn them off without modifying the plastic. #### Padding Apply padding where desired with any standard orthotic glue. #### Heat Modifications With a heat gun, material is pliable for adjustments at 70C-85C without melting. #### Chemical Modifications **Do not use acetone**. Isopropyl alcohol or Goo-gone is recommended for removing residual glue. ### FAQs - [Pediatric Articulated AFO Product Information](https://www.help.protosthetics.com/galileo/afo?hsLang=en) - [See this article to learn how to load filament](https://www.help.protosthetics.com/galileo/loading-the-galileo-op-printer?hsLang=en) - [Account & General Information](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#main-content) - [Account & Permissions](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#account-permissions) - [Policies & Guarantees](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#policies-guarantees) - [Printer Returns](https://www.help.protosthetics.com/galileo/account-general-information?hsLang=en#printer-returns) - [Scanning Options](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#main-content) - [App & Hardware Setup](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#app-hardware-setup) - [Scanning Best Practices](https://www.help.protosthetics.com/galileo/scanning-options?hsLang=en#scanning-best-practices) - [Ordering Process & FabOne Portal](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#main-content) - [Placing & Managing Orders](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#placing-managing-orders) - [Print Control](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#print-control) - [CFAB Options](https://www.help.protosthetics.com/galileo/ordering-process-fabone-portal?hsLang=en#cfab-options) - [Galileo Product Options](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#main-content) - [Prosthetic Products](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#prosthetic-products) - [Orthotic Products](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#orthotic-products) - [Customization & Fitting](https://www.help.protosthetics.com/galileo/galileo-product-options?hsLang=en#customization-fitting) - [Filament & Printing FAQs](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#main-content) - [Filament Loading & Handling](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#filament-loading-handling) - [Preparing the Printer](https://www.help.protosthetics.com/galileo/filament-printing-faqs?hsLang=en#preparing-the-printer) - [Hardware Troubleshooting & Maintenance](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#main-content) - [General Tips & Tricks](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#general-tips-tricks) - [Connection Troubleshooting](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#connection-troubleshooting) - [Hardware Troubleshooting - Pro](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-troubleshooting-pro) - [Hardware Maintenance - Pro](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-maintenance-pro) - [Hardware Troubleshooting - Galileo O&P/Pro 2](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-troubleshooting-galileo-op-pro-2) - [Hardware Maintenance - Galileo O&P/Pro 2](https://www.help.protosthetics.com/galileo/hardware-troubleshooting-maintenance?hsLang=en#hardware-maintenance-galileo-op-pro-2) [![ProtostheticsGalileo Logo-1](https://www.help.protosthetics.com/hubfs/ProtostheticsGalileo%20Logo-1.svg "ProtostheticsGalileo Logo-1")](http://protosthetics.com) 510 6th Ave N, Ste D, Fargo, ND 58102 USA [mailto:success@protosthetics.com](mailto:success@protosthetics.com) Copyright © 2026, Protosthetics
