What happened

NASA’s October report describes twelve KREPE-3 capsules carried aboard a departing Cygnus cargo spacecraft. The experiment uses the vehicle’s planned reentry to gather data on thermal-protection materials and designs.

One candidate is a 3D-printed heat shield developed through work at NASA Johnson and Oak Ridge National Laboratory. Other capsules investigate different materials and shapes, so the mission should not be described as twelve identical printed shields.

Sensors and satellite transmission are intended to record conditions during descent. The announcement describes a flight experiment and its objectives; it does not report final performance results or qualify the printed design for carrying astronauts.
