Hi Kate, i really enjoyed your post and your individual argument 🙂 I also do not believe that a 3D printer is an essential purchase for every library to accommodate a maker space environment,i feel that when i think of a maker space environment i think of art and craft not the technical aspect of a 3D printer which is something i would expect tot see in a space such as the Edge. And Remember what Daniel said at the Edge tour… In 3-5 years time anyone will be able to purchase a 3D printer, they will cost a tenth of the price and you will be able to purchase them in Big W! 🙂
