| Abstract Scope |
In the proposed work, some investigations were carried out to enhance the surface roughness of the polymer patterns by applying some coatings. Different materials like Different infill patterns were considered while developing the 3D printed patterns, out of which Gyroid and Cubic infill patterns were found to have better compressive strength than the other infill patterns.
The 3D printed polymer patterns have an inadequate surface finish compared to the wax patterns. Hence, an attempt was made to enhance the surface roughness of the polymer patterns by creating a thin wax coating around them by dipping them in a paraffin molten wax bath. Several experiments were conducted by varying wax bath temperatures, dipping time, etc. It was found that the wax bath’s temperature of 69oC and a dipping time of 2 seconds could improve the surface roughness of the polymer pattern to a significant level. |
