So, a laser is like a die cut machine?
Yes, but a laser is far more powerful and flexible. With a die cut machine, you are limited to cutting the shapes that you have dies for. If you want to cut a new shape (or cut an existing shape in a different size), you either have to order the appropriate die or, if such a die does not exist, try and get the manufacturer to create a custom die for you. With a laser, you only need to draw the new shape. Also, a laser can cut multiple shapes from a piece of fabric all at the same time. With a die cut machine, you typically cut only one shape at a time.
