AM materials standards
Ann R. Thryft   11/15/2013 11:50:30 AM
NO RATINGS
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.

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

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.

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

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

Greg, that's a good point about delicate designs and less support structure. That one hadn't occurred to me.

Agreed, notarboca. It's tough to discuss anything intelligently if you can't be sure you're talking about equivalent materials with the same properties.

I am enjoying your continued thorough coverage of this space, Ann. I would think the durability issue would be a big one, and it's interesting to see the techniques being devised to address it.

Thanks, Elizabeth. Depending on the process and post-processing, durability can be, as we've seen, good enough in metals for rocket engine parts, among other things. Plastics can be another story, but it's worthwhile remembering that 3D printing has been used in aerospace and high-end race car applications for several years. What we need is a metric we can all point to if we're going to have any meaningful discussions.

3D Printing with metal clay
BillStruve   11/26/2013 9:23:46 PM

A new way of 3D printing is to extrude metal clay, like Metal Adventures Inc. BRONZclay.  After the print is air dried, it is fired in a kiln to fuse the metal particles in the clay into solid metal.  This technique is used in the Mini Metal Maker: http://minimetalmaker.com/press  It is also being used successfuly in the Netherlands.
