Thanks, Nadine. Actually, it's more than visual resemblance: with different material properties in different parts of the model that more closely resemble the product, the model does a better job of simulating form, fit and especially function.

It sounds like the digital materials give more visual options for designers/engineers (and sales teams) to see the model as accurately as possible for actual materials are applied.

Nice progression, especially for the accessories market.

"Digital materials" is Objet's term. As Bradshaw is quoted as saying, they are combined digitally, meaning via computer--preprogrammed--during printing, versus making parts of a prototype separately, and mechanically combining them after printing. The point is that engineers can program the printer to print different material property combinations in different parts of the model, as Objet describes on the page at the link we gave in the article.

Beth, that is an interesting statement, isn't it?  "A digital material".  That's going to cause me to look at everything I see today and ask "Is that digital?"

Materials mix key to 3D printer adoption

Objet has really done a great job pushing a variety of materials for their 3D printers, thus upping the utility of how they can be used. My question is what exactly makes a material "digital"? I get the ability to mix and tune the properties so that they can mimic more traditional materials. But how is that done in a digital fashion? Is there some sort of software algorithm that handles the finetuned mixing or is it a property in the material itself?
