  1. Pregled raspoloživih tehnologija i biomaterijala pogodnih za brzu izradu prototipova Mr Jelena Milovanović

  2. Direct Metal Laser Sintering-DMLS(Direktnolaserskosinterovanjemetala)

  3. DMLS-EOSINT M270

  4. Materijali • EOS Titanium Ti64 / Ti64ELI • EOS CobaltChrome MP1

  5. Electron Beam Melting

  6. Materijali • ASTM F75 CoCr legura • Ti6Al4V Titanium legura • Ti6Al4V ELI Titanium

  7. Biomaterials for 3D printing • commercialized composite powder materials. • Bone replenishment is formed by mixing PMMA (polymethylmethacrylate) and fine granule of bone cement • The ready bone cement is a compound consisting of 90 % ofpolymethylmetacrylate, (PMMA), the rest are mainly crystals of barium sulfate or Zirconium oxide .

  8. Biomaterials for 3D printing • Three-dimensional printing (3DP) technique was used to fabricate scaffolds in combination with natural polymer and water based binder. • a unique blend of starch-based polymer powders (cornstarch, dextran and gelatin) was developed for the 3DP process.

  9. Biomaterials for 3D printing • Used material: spaydried Hydroxyapatite(HA)-granulate named V5 • Besides the main component HA it contains polymeric additives to improve bonding and flowability • As a binder we used Schelofix which consists of water soluble polymeric compounds

  10. Biomaterials for 3D printing • Used material: developed a powder mixture comprising tetracalcium phosphate(TTCP) as reactive component and β-tricalcium phosphate (β –TCP) or calcium sulfate as biodegradable fillers, • Conventional 3DP eqipment can be used to print this material with an aqueous citric acid solution as binder. • No organic solvents are needed in the printing process.

  11. STUDY 5 - Biphasic Calcium Phosphate/Poly-Dl-Lactide-Co-Glycolide Composite Biomaterial as Bone Substitute • Prof dr Dragan Uskoković i Prof. dr Nenad Ignjatović • Sinteza nanokristalnih i nanostrukturnih kalcijum fosfata i kompozita za rekonstrukciju koštanog tkiva predstavlja osnovno polje istraživanja dela grupe za nove materijale i procese Instituta tehničkih nauka Srpske akademije nauka i umetnosti (ITN SANU) u Beogradu.
