For maximum efficiency with cutting printables, consider in investing in a cutting tool like the Silhouette Cameo or Cricut Explore. Both allow you to print out any shape and cut around the printable. It takes minutes to set up the file and cut compared to hours of using scissors.
The great thing about printables for personal use is that you don't need to have a fancy printer or pay a printing company a fortune. Simply print graphics at home with an inkjet or color laser printer. You can find a printer for as little as $60 or upwards of $2000. Don't think you need an expensive printer to create incredible graphics. A printer in the $100 range should work fine.
