3D CAD is much more difficult than 2D for Laser Cutting. But what keeps me from the 3D printing world is all the work that seems to need to be done after the print job is done with the job, especially with lower end less expensive 3D printers. However, with the lack of decent in scale, knickknacks, cars, trucks and such, a 3D printer is getting closer and closer to being on my desktop.
