Traditional CAD software provides basic rendering tools, but they only show the geometry of a model, not how it would appear after printing. Extrudio changes this by generating realistic images based on the G-Code instructions a 3D printer uses. This approach captures layer lines and printing artifacts like stair-stepping on curved surfaces. The tool allows users to visualize parts in different environments, such as a kitchen or studio setup. It is particularly useful for those selling 3D printed items online, though physical prints still offer superior realism. The software can also help in showcasing different colors and printing techniques without the need for actual production.
