Post Print Modifications

Some of our AFOs are currently printed WITHOUT holes or slots for straps, rings and other componentry. These are to be created by the orthotist after receipt of the device. There are several other ways an Orthotist can modify a 3D printed AFO if it needs adjustments.

Here is a list of modification instructions.

Drilling Holes

• Drill pilot holes whenever reasonable.

• Hold device in a vice to minimise deflection in device and to minimise vibrations during drilling.

Creating Slots

• This can be done using a routing bit

• Hold the device in a vice to minimise deflection in device and to minimise vibrations during routing.

Riveting

• Drill a pilot hole and hold device in a vice.

• Exercise caution here: device should be held flat against riveting surface.

Grinding Corners/Edges

• This can be done using a grinding bit or belt sander

• You must ensure met heads retain similar radius as in original print to avoid fractures

• Areas that are adjusted through riveting/grinding should be smoothed/buffed to ensure surface is smooth. This is to minimise the chance of microfractures being created in the process of grinding edges and corners.

Shape Changes

• This can be done through heating. Please see heating instructions for Nylon 11 and Painted Finish here
