Purpose and goal
The goal of the project was to investigate the possibility of making degradable bone scaffolds by the use of 3D-printing. Fused deposition modeling (FDM) was the method used, and 2 different machines were utilized in the project. The ultimate goal was to produce a structure with the correct porosity for enabling ingrowth on bone tissue, while maintaining a high mechanical strength in order to work as a load bearing implant. The project reached these goals, and gave the company valuable knowledge to further develop the product.
Results and expected effects
The project showed that it is possible to use the FDM-technique to print a degradable bone scaffold. This creates an easy way of producing an implant which stimulates the ingrowth of new bone, will be resorbed by the body with time and also can be tailor made for each patient. The results obtained from the project makes it possible for Promimic to commercialize a new and unique product.
Approach and implementation
The project was planned to be finished by the end of November, but due to technical difficulties it was prolonged until the end of January. Apart from this the project proceeded according to plan and gave very positive results and new knowledge.
