Fig 1. Study design
Fig. 2. Results of the EDS analysis of colored deposits on the surface of calcined allografts: distribution of chemical elements across the yellowish deposit area, several colors of some compounds correspond to the same set of chemical components appearing in different orders in the EDS results, for example Ca/P/O/Na/Zn or Ca/P/O/Zn/Na
Fig. 3. Results of the EDS analysis of the surface of the calcined allograft with no identifiable deposits: distribution of chemical elements across the allograft area. Several colors of some compounds correspond to the same set of chemical components appearing in different orders in the EDS results, for example Ca/P/O/C or Ca/C/P/O
Fig. 4. Allograft-derived 3D-printed complex-shaped sintered scaffold. Convex and concave areas of the object and the layered structure are visible; microcracks in the layered structure of the object emerged during heat treatment
Fig. 5. Mechanical behavior of the 3D-printed allograft material sintered at 1300 — during the mechanical compressive test (6 samples) and tensile test upon cleaving (6 samples)
