A new study describes the development of a novel hybrid polymer suitable for producing 3D-printed scaffolds on which living cells can be seeded to create engineered tissues.

The ability to use these hybrid polymer spools with easy-to-operate, commercial 3D printers is demonstrated in the study published in 3D Printing and Additive Manufacturing.

Syracuse University researchers Lucas Albrecht, Stephen Sawyer and Pranav Soman developed the methods used to produce polycaprolactone-based polymers and to fabricate scaffolds using a Makerbot 3D Fused Deposition Modelling printer.

In the article “Developing 3D Scaffolds in the Field of Tissue Engineering to Treat Complex Bone Defects,” the researchers report how they overcame the challenges associated with creating composite polymer spools.

The authors incorporated living cells mixed with gelatin hydrogels into the scaffolds and achieved high levels of cell survival. They discuss potential applications of these techniques, including tissue engineering to repair complex bone defects.
