Feeling disconnected from 3D printing? Where do you start?
Through my consulting, I have met many product designers, inventors and artists that have an interest in using 3D printing. Many of them don't know where to start, what is involved or what the process even looks like.
I am going to aim this post at artists but the principles are generally the same no matter what you do. So, here are the basic requirements to work with 3D printing. This is in no way comprehensive, instead it is a very general overview.
1) 3D printing requires a watertight 3D virtual model. To create that virtual model, you will need to work with a 3D CAD designer or learn 3D design software.
If someone is creating your 3D virtual model, you may need to provide them with orthographic views of your design and/or provide measurements. Depending on who you work with, some people can, or are comfortable, working from a single sketch. But generally, the more information you can provide, the less time it takes to create the virtual model. Usually, less time means less cost. If you only provide one view, they will have to infer/imagine what the design looks like from other angles.
2) There are many different 3D printing technologies. You should understand the benefits and limitations of each technology or at least have a general understanding of the technology you're planning to use. It will help you choose the best 3D printing technology for your project. It's a good idea to not rely on a manufacturer's sales material.
For example, Fused Filament Fabrication (FFF) technology typically offers lower costs and larger build sizes but has the roughest surface finish and can be slow in producing parts. Refer to the images below of a couple diagrams of different 3D printing processes.

3) Post processing will most likely be needed for your 3D prints. This may involve traditional hands-on techniques to smooth and paint your print or even casting. It could also involve other technologies like machining. If you do your own 3D printing, post processing may involve removing supports by hand.
Please keep in mind, this is a very, very general overview of what's needed for a 3D printing project. There are many finer facets to each of these points and considerations that are specific to each project.
