Researchers headed by the University of Science and Technology of China have demonstrated a design optimization scheme that decreases the material needed to 3D print a solid object by 85 percent. They used, as an input test model, a version of the famous statue known as the flying horse of Gansu, shown here. (Source: Wikimedia Commons)

I agree, Ann, the ASTM standards will provide a framework to stand on as the strength and durability debate continues.

@far911: Respect !!! What is your opinion on this.. Which of this is important most for you .. Durability or Cost ????

Optimized Support Structures

I am especially interested in the optimized support structure (slide 3) which shows a dramatically reduced amount of support structure material being used.  This is can be very significant for certain applications.  Not only will this save money (less material used), but will also allow for a much faster cleanup of parts (saves time).  In addition to this, certain designs have very delicate features.  By creating a minum amount of material to remove on these delicate features, part breakage and damage can also be reduced.

I still believe durability will be an issue along with cost effectiveness.

AM materials standards

Although I listed it last, the ASTM standards effort to determine the mechanical properties of materials made with AM processes just might end up being the most important of these. There's continuing debate in the industry about the strength and durability of materials made by layering, and a metric for discussing and assessing them is a good start.

A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
Although bio-based polymers face challenges from petroleum-based polymers, in certain markets they can displace the petro-based incumbents. Here are six new bio-based and renewable plastics for a variety of applications.
BASF has developed tools and initiatives to help engineers use more of its renewable materials in their designs, more effectively, as well as to build parts using them with more predictable performance.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
