7. Biomaterials for 3D printing
commercialized composite powder materials.
Bone replenishment is formed by mixing PMMA (polymethyl methacrylate) and fine granule of bone cement
The ready bone cement is a compound consisting of 90 % of polymethylmetacrylate, (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.
