Meaning
Specialized measurement technique used to verify the internal and external geometry of 3D-printed orthopedic structures. Precise porous implant lattice metrology identifies deviations in strut thickness and pore size that could affect the rate of bone ingrowth. It relies on high-resolution imaging to capture the complex architecture of the scaffold.
Structural Verification
Verification of the lattice integrity involves checking for blocked pores or thin struts that could lead to mechanical failure. The software analyzes the connectivity of the cells to ensure that the fluid can flow through the entire structure. This analysis is necessary for ensuring that the implant will support biological life once it is placed in the body.
Dimensional Precision
Precision of the struts is measured in micrometers to confirm they match the intended design. Small errors in the printing process can result in a lattice that is too stiff or too flexible. Accurate metrology allows the manufacturer to calibrate the printer for consistent results across different batches.
Bio-Compatibility Assurance
Assurance of the biological function of the implant is tied to the physical dimensions of the pores. If the holes are too small, the bone cells cannot enter, and if they are too large, the structural support is insufficient. The metrology report provides the evidence needed for regulatory approval and clinical use.
