If you want to make your own patterns for Azulejo tiles, the first step in the Instructables project is to show the manufacturer's design process. After collecting non-commercial photos online, goworthm uses Gimp to create outlines for each color except white. After creating JPG files, these files will be converted to vector files (SVG).
Software engineers use TinkerCAD, a free browser-based CAD program, to convert vector files into a 3D world. Simply import the file and make it about 1 mm thick, and place the tile on a square base with a 1 mm thick wall around it, which will help capture the white drywall coating you need later.
The next step is to 3D print the parts of the tile. Instructables user goworthm recommends using PLA instead of other filament types because it is easy to print and does not distort. He also suggested using thick layers for printing and personally lifting each layer to 0.2mm.
If there is no multi-material 3D printer, the blue and orange parts need to be printed separately and assembled afterwards. You may need to use an exacto knife to clean the edges so that the orange portion fits snugly against the blue tile.
Next, using pre-mixed drywall paint, you need to pick up and spray the material across the print to fill all the holes and gaps along the way. Once the putty is spread over the entire 3D printed tile, scrape off the excess and make sure the surface on the tile is smooth and smooth.
If the printed part is visible, there is no need to warn because it will tell you how to deal with this issue in the following steps. Now putty is applied, let it dry overnight, and then go to the final post-processing step.
According to the manufacturer, he used hand-held sanders and orbital sanders in the project, but eventually found the latter to be more successful in large open areas. However, manual sanders still need to remove extra turns and smooth the filament.
Finally, in order to obtain a visually appealing shimmer, you need to apply some Rustleum semi-gloss transparent paint to the tile surface. This may require two coats, so please be patient and let the first few layers dry before judging the results. Instructables users also plan to use food safety resins to allow him and his wife to turn tiles into cutting boards.
