| Popis: | 107 A new bone repairing biomaterial, ALG/HEMA-HAp, was a semi-double network (S-DN) hydrogel fabricated from 2-hydroxyethyl methacrylate (HEMA) and ethylene glycol dimethacrylate (EGDMA) in the aqueous mixed dispersion of hydroxyapatite (HAp) and sodium alginate (ALG). The mechanical properties, moisture, shrinkage and morphology of all samples were investigated. Among them, The ALG/HEMA-HAp 10% xerogel showed the stress is 16.378 MPa and the elongation is 4.61%, which might be comparable to the human’s trabecular having the tensile strength of 10 to 20 MPa and elongation of 5% to 7%. Finally, we use Stereolithographic 3D Printer SWIM-ER, and then succeed to print out a 3D bone shape after adding Irgacure 127 1.00wt% and Kemisorp 11S 0.04 wt%. |
