APPLICATION NOTE 5940
SECURE 3D PRINTING - THE NEW DISRUPTIVE
TECHNOLOGY - AND WATCH THE MARKET
GROW
By: Hamed Sanogo, Executive Business Manager, Secure Info & Authentication
Abstract: This application note focuses on modern 3D printing, also known as additive manufacturing, which
is making a three-dimensional solid object of virtually any shape from a 3D model or other electronic data
source. It discusses the Razor-Razorblade business model which involves selling a main item at a discount
just so the complementary (often disposable) secondary goods can be sold at a considerably higher price.
This same business model has been successfully used for the traditional printer market, but the model
works only when there is a strong IP protection scheme implemented against cloning, counterfeiting,
replicating, and imitating disposables. The DS28E15 DeepCover
secure authenticator IC is the right path
for selling more 3D printers. Now, here is how we get a 3D printer in every home!
It is fair to say that 3D printing is revolutionizing the manufacturing landscape. Can you imagine sending a
3D print of your feet to have a pair of shoes customized for you? This is not really that far-fetched.
Modern 3D printing, also known as additive manufacturing, is the process of making a three-dimensional
solid object of virtually any shape from a 3D model or other electronic data source. As an additive
manufacturing method, the manufacturer “adds” material to an object, layer by layer, to create the final
product (Figure 1). Given the staggering sudden growth of 3D printing and the several different 3D
printing methods, all indications suggest that 3D printing is, or should be, considered a disruptive
technology. Following from that assertion, to say that 3D printing will change the world is not at all a
stretch.
