| 제목 | Mechanical Strength of 3DP Structure Reinforced with Natural Polysaccharide Adhesive |
| 초록 | For the 3D printing industry, powder bed and inkjet 3d printing, known as 3D printing (3DP), brings a new level of considerable material flexibility to the manufacturing industry. However, the commercial binders and cover adhesives are toxic and can induce eye and respiratory irritation. One of the solutions is to combine powders and binders with stronger and biocompatible adhesives. One of which is derived from polysaccharides. Here, we suggest a new 3DP systems for manufacturing the powder based structures. The powder is composed of calcium sulfate hemihydrate which can be transformed to a ‘needle-shape’ when it adsorbs water based binder. Then the powder undergo physical crosslinking and the binders help to make more solid structures. By binding with polysaccharides solution and stacking layer by layer, we demonstrate the sturdy structures are made. Chemically, calcium of the powder mediated coordination crosslinking gives strong mechanical property. The study suggests that biocompatible adhesives can enhance mechanical properties of powder based 3DP structures by chelation. |
