About this Product
This is a model used to test printing detail of various materials. To see a detailed key and a high resolution example printed in Stainless Steel, visit http://www.thefrankes.com/wp/?p=2138. This object is tiny and includes many details in the 0.0 to 1.0mm range; it many not print in all materials, but I've made it available in all in case you want to try.
