It means 2d whereas 3d means three dimensional
3d = three dimensional Can be formed in a plane 2d = two dimensional.. Visualised in space

3D means three-dimensional, i.e. something that has a width, height, and depth. Our physical environment is three-dimensional and we move around in 3D every day. The 3D printer is the device by which we do 3d printing material. 3D printing is the technology. I took service from Iannone 3D, which is in New jersey area offer quality 3D prototyping service at a price point.
3D quite simple.
