Paragraph starter

The fabrication of resorbable bioceramic implants, such as Tri Calcium Phosphate (TCP), via selective laser melting necessitates careful control over process parameters. Research indicates that CO2 lasers are effective due to TCP's absorptivity in the far-infrared spectrum. Optimization of laser power, travel speed, and powder layer thickness is critical for achieving the desired porosity, which is essential for subsequent bone cell colonization and implant integration, as demonstrated by Aubry et al. (2015).
