![]() The raster image, then, is seen as just a square piece of metal. The raster file uses colored pixels to display different images, but since CNC machining software doesn’t differentiate between colors and pixels, it only sees the boundaries of the part being where the pixels stop. You can see the difference between how these two file types appear in most software in the image below. It will reject all files that are not vectors. ![]() A raster file’s clarity depends on its resolution and it doesn’t scale correctly, so the laser won’t be able to “find” the true edge lines of your part. These coordinates are understood by the laser because they are determined through a set of mathematical equations, unlike raster files which are just graphic images, or pixels. We require vector files for laser cutting because in the background, vector files are graphed with geometric shapes, which act as a set of coordinates for the laser. Why Are Vector Files Required for Laser Cutting? We promise this is actually much easier than it sounds! In this article, we’ll walk you through a step by step process to vectorizing your files using Inkscape, a completely free and open source graphic design software. It’s better to just convert your own raster file to a vector file manually. This may seem like the fastest, simplest solution, but online file converters have a nasty habit of producing the lowest quality files that are the most difficult to process. Namely, a vector file.īefore we get into exactly how this conversion can be made, it’s very important to remember that whatever you do, do not use an online file converter. ![]() If you have a design in the form of a JPEG or PNG that you found or purchased online which you want to turn into a laser cut part, you will first need to convert that design to a different file type.
