Because of the way that 3D printers lay down layer upon layer of plastic, it introduces an inherent weakness along the layer lines. This is referred to by engineers as 'anisotropic strength' meaning the strength isn't the same in all directions. Look at this view of how noodles are laid down in each layer. Each successive layer bonds, or adheres, to the previous layer by melting the surface of it as it is extruded. What you will find with 3D printed objects is that they wil

Well, you finally bought a 3D printer and you're wondering what the heck you're going to make with it! Even though you're probably having difficulty thinking of something to make right off the bat, the list is almost infinite of what you can make with your new printer. Limitless, right!? Not quite. While you can make almost anything, there are some limits to the way things have to be done with a 3D printer. Well, not just some, a lot of limits and constraints. You'll nee
