Design of 3D printing materials based photoactivating acryl-polyurethane to add flexible functionality to exquisite structures |
| 초록 |
In order to improve the flexibility of the photocurable 3D printing structure, the structure was successfully fabricated by appropriately including the designed acryl-PU. It was confirmed that the flexible properties of the 3D structure improved as the polyurethane content increased. An acryl-functionalized polyurethane series were synthesized using poly(tetramethylene ether) glycol-methylene diphenyl diisocyanate (PTMG-MDI) oligomer based on urethane methacrylates. The raw materials of acryl-PU were analyzed through UV absorbance analysis and viscometer. Acrylic additives and photoinitiators were important elements for fabricating 3D printed structures. Structures with precise fine patterns were manufactured by controlling the inherent viscosity and exposure conditions of the materials. The results showed that acryl-polyurethane demonstrated the potential applicability in field of photocurable 3D printing materials. |
