The accessibility of cost-competitive renewable materials and their application in additive manufacturing is essential for an efficient biobased economy. We demonstrate the rapid prototyping of sustainable resins using a stereolithog. 3D printer. Resin formulation takes place by straightforward mixing of biobased acrylate monomers and oligomers with a photoinitiatior and optical absorber. Resin viscosity is controlled by the monomer to oligomer ratio and is determined as a function of shear rate by a rheometer with parallel plate geometry. A stereolithog. apparatus charged with the biobased resins is employed to produce complex shaped prototypes with high accuracy. The products require a posttreatment, including alc. rinsing and UV irradiation, to ensure complete curing. The high feature resolution and excellent surface finishing of the prototypes is revealed by SEM. In the experiment, the researchers used many compounds, for example, 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5Safety of 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene).
2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene (cas: 7128-64-5) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Safety of 2,5-Bis(5-(tert-butyl)benzo[d]oxazol-2-yl)thiophene
