Descriptions of names. This is a general overview of what's involved. There are a few ways to go about taking an idea to a physical object with a 3D printer... I chose to use a CAD (Computer-aided design) program and a 'Slicer' program, for now. A slicer program takes a 3D model and slices it into layers then takes those layers and generates the paths for the machine to follow to make your part. It also takes into account and allows modification of the specifics of your machine and any customizations that need to be made for this part such as: Increased or decreased temperature, Increased or decreased print speed, part wall thickness, seam location, ect. An alternative to a Slicer is a CAM (Computer-aided Manufacturing) program. Typically, CAM software comes as a plugin or add-on to a larger CAD program. CAM software is typically more integrated with the software that it plugs or adds on to and provides a more unified experience. Most CAM software is geared more towards making tool paths for CNC mills and lathes but can also be used for 3D printers. Most slicer software is more 3D printer focused. Both CAM and slicer software generate G-code to feed into a physical machine. Keep in mind I am being very general in my descriptions here. You can use any 3D design software as long as it has the ability to output a .STL file. For some reason this file type has become, kind of standard for sharing 3D models and for inputting into slicers. I think it has something to do with it being an open 3D file format standard but, that doesn't mean that it is a good file format for modifying the model once it has been created. I have come across some shared models that were not complete and trying to modify a .STL file? well... Maybe I just need more practice, but it seems like it is an exercise in futility and it would be faster to start from scratch and remake the model. So, we have two basic program types and three file formats to keep in mind throughout this process: Programs: 1. CAD Software 2. Software to generate G-code File Types: 1. Native 3D file type 2. .STL file type 3. G-code file type A basic workflow.The result of a basic workflow for 3D printing then, consists of:
My next post will go into what programs I am currently working with and why I chose them. Thanks for reading I hope you found this useful!
