Images into 3D models Zoom in to clean the lines so the pixels form a solid line -images into 3D models Bucket fill tool used on the fixed scan – images into 3D modelsīefore we can import out sketch into our 3D modelling software of choice, I will be using TinkerCAD as it is free, easy to use and does what I need it to do for now. GIMP 2.8 – images into 3D models Cleaning up the lines – So export the image and replace the old one. Now use a black bucket tool to fill in the areas you want solid and keep the bits you want be cut out in white. I also wouldn’t bother cropping the image. You may also want to use a white pencil tool to clean the lines a bit. I use the pencil tool with the pixel brush to go along the lines to make them solid as we will be using the bucket tool later on. So load in our image and you will want to make the lines solid. Now we have to fix the image in image editing software, I will be using GIMP 2 a free image editing software (). Just adjust those settings so the lines are pretty much solid but the background is still white. While you are still in your scanner settings you may want to decrease the brightness a bit as well as increase the contrast a bit if you can. This should also allow colour pictures to be scanned, such as a key. But make sure to use black and white setting, that is very important as you don’t want any stray colour from anywhere on your scan. Now scan your design as a image (JEPG or PNG) and if you are on a proper 2D scanner use a medium setting for resolution, it’s not a massive deal here about DPI. “Office Lens” by Microsoft work well for this and it is available and android and IOS. The next step is to use a 2D scanner, most printers have these now or if you don’t have a scanner you can use a app on your phone which uses your phone’s camera as a scanner. I like to use a pen to make strong bold line which will be easier to work with but a firm pencil should work well. Of course with my coffee art stencil I will add enough gap for the powder to go through. So there aren’t any really close gaps, you should know your 3D printer’s capabilities. Okay so the first step is to draw you design, however while drawing try to make it work on a 3D printer. A coffee art stencil is a stencil used to sprinkle chocolate or other powder onto top of coffee in shapes. For the main tutorial I will be showing how to convert a 2D drawing into a coffee art stencil. I will include 2 examples as well, one of which is how to replicate a key. In this tutorial I am going to go through the steps, one by one in detail. For example you could turn a child’s drawing to a 3D object, a hand drawing is much more personal than a computer generated CAD drawing. Well there are many reasons : whether you want a model of a complex logo that would require lots of time and effort to replicate, or you don’t know how to design and want a starting point and 2D drawings can give your designs a personal touch. Why should you want to turn images into 3D models.
