Fabrication of PLA based composites through the employment of ۳D printing for biological applications

Hydroxyapatite is a calcium phosphate that is a very important ceramic applicable in biomaterials. Nano hydroxyapatite has been considered as a biological material for the use in body implants due to its similarity in size, crystallography and chemical composition with human hard tissues. In this research, hydroxyapatite was produced by combustion synthesis method and then it PLA/HA composites were manufactured via ۳D printing method. Hydroxyapatite nanoparticles were prepared using calcium nitrate, ammonium phosphate, urea and nitric acid. In the continuation of the research, XRD was used to evaluate the phase structure of the produced hydroxyapatite and biodegradability test was also taken from PLA+ ۱۰ wt% HA compounds. From the FTIR analysis, the presence of carbonyl and phosphate groups in the PLA/HA composite were confirmed.
