In some examples, an apparatus comprises a platform having an upper surface to contact a plantar surface of a human foot positioned on the platform, a first pressure sensor to sense a pressure applied to the upper surface by a heel of the human foot, and a first probe extending through an opening in the platform and movable vertically upward through the opening to probe an adipose layer on a bottom of the heel. The apparatus also comprises a first actuator to displace the first probe upwardly against the adipose layer with a predetermined force, and a linear displacement sensor to sense a vertical displacement of the first probe.

A multiple-pattern fiducial for a heterogeneous imaging sensor system. The multiple-pattern fiducial includes a first pattern detectable by a first wavelength of electromagnetic energy, and a second pattern detectable by a second wavelength of electromagnetic energy.

In an example implementation, a method of cooling a 3D build volume includes receiving a 3D object model that represents a 3D part to be formed in a build volume, and determining a placeholder position for forming a placeholder part within the build volume. Based on the placeholder position, a 3D part position is determined for forming the 3D part within the build volume. The method also includes controlling components of a 3D printing system to form the placeholder part in the placeholder position within the build volume and to form the 3D part in the 3D part position within the build volume.
