STT System - Solescan Rubra

Solescan Rubra is a three-dimensional foot scanner based on laser light which provides an accurate 3D model of a patient’s soles. The acquisition of precise and reliable digital data of the foot allows the doctor to detect underlying problems in foot function and gait that would otherwise be unseen. Additionally, the 3D foot model allows generating customized insoles quickly and with great precision.

Apart from soles (in loadbearing, semi-loadbearing, non-loadbearing positions), Solescan Rubra can actually scan phenolic foam casts and plaster models (or casts made from other materials).

The combination of Solescan Rubra with STT’s computer applications is a powerful tool for the production of insole orthesis which are tailor-made to individual patient needs.


Key features

  • Very easy to set up and use
  • Excellent sensitivity
  • High resolution
  • Color or monochrome, interline, progressive scan, with 640x480 resolution cameras
  • Global electronic shutter allows capturing objects in high-speed motion

Acquisition software

The complete Solescan Rubra package includes the latest version of STT scanning software, which is user-friendly and updated with the latest algorithms. The application allows the user to visualize the foot from different points of view; to carry out accurate measurements; to introduce additional notes; to define personalized insole orthesis; and to manage patient-related data in a comfortable way. 3D


Insole Studio

Insole Studio is the natural complement of Solescan Rubra. It allows the user to load digitalized surfaces generated with the scanner and to design customized soles in a straightforward way. Some of the key functions and tools of this software are described below.

  • Shoe horns library:

    Adjustment of the surface to different insole sizes.
  • Spot height maps:

    Show the digitalized surfaces with different colours, depending on the height of each point.
  • Layer editing system:

    Each operation on the surface is independent, so they can be individually disabled or even applied to another surface.
  • Set of correction pieces:

    they allow the user to modify the surface obtained.
  • Lower heel:

    Definition of a circular or oval zone where the height you want to give the zone can be adjusted, according to a curve.
  • Middle part of the foot:

    Definition of a shape that covers the middle part of the foot. Cant: Definition of the inclination desired for a surface, set through a curve.
  • Heel support:

    Editing of surface contours in the zone selected by the user. Different profile curves can be defined along its length.
  • Manual correction pieces:

    User-generated correction pieces based on digitalized surfaces, saved in a library for later application.
  • Flattened tip definition:

    A zone of the scan that is set at a particular height, making the transition softer through a compromise.
  • Filtering:

    Makes the digitalized surface softer. Transformations: Allows the user to move and rotate a digitalized surface.
  • Export:

    It is possible to export files to STL format, for machine vision.



Insole manufacturing

The last step to obtain made-to-measure insoles for patients is their manufacture. To do this, the Insole Studio numerical control (CNC) program is used to make insoles using different milling machines or robots. CNC file formats generated by Insole Studio:

  • G-Code

    The most common and widely used programming language for numerical control machines like milling machines.

    A specific numerical control machine programming system for ISEL cards.
  • Robot KUKA

    Insole Designer exports files in TAP format. These files contain the progamming instructions for KUKA robots for the machining of the customized insole, using three or six axes.
  • CAM Applications

    Insole Designer exports the insoles designed by the chiropodist in the following formats: STL, OBJ, DXF and VRML. These formats are accepted by CAM programs such as CUT3D, which generate the numerical control program for any kind of milling machine or robot.
  • Materials

    The customized insoles geenrated can be machined in almost all kinds of material, such as EVA (any density), polypropylene, etc.
  • Thermoforming

    Manufacturing thermoformed insoles requires the machining of the insole moulds. Insole Designer generates the files required for the machining of moulds for different materials, such as plaster, expanded polystyrene, etc.
