CHAPTER TWO It’s Not About the Tools, but . . . ​ 3D Printing Has a Lot to Offer “I enjoy the excitement of 3D models coming together. It takes time but it’s so much fun.” —­Sara, age 9 Be Your Best Cheerleader If ­ there ever ­were a contraption that caused quite the controversy at our school, it would be the three-­dimensional (3D) printer. For about three years, ­there was a ­running joke between myself, the vice principal, and our principal and associate head of school. It went something like this: Me: “I want a 3D printer for our library. We could do so much with it.” Administration: “I’d like to have a clear understanding of how it would be valuable to the curriculum before purchasing a 3D printer.” Me: “­There are so many opportunities to amplify the curriculum with a 3D printer. We can enhance the second grade unit on rocks and miner- als and ­simple machines, for example.” Administration: “Oh, look. It’s 3:05 and Stacy’s mentioning the 3D printer again. What has it been, like five minutes since her previous request for this? Look, it’s not about the cost. It’s about ­ whether or not it ­ will add value to the learning.”
