@ChasChas - good question. My guess is that the old design would be printed first so they get an apples-to-apples comparison for their evaluation of the basic mechanical properties.

are these componets used right out of the printer (except the obvious) or do they go through post scintering processes like hot isostatic pressing HIP to improve the density and grain strcture. thanks for a awsome publication

Thanks, ruffel, glad you liked the article. That's a good question. NASA didn't say what kind, if any, post-sintering processes they're using. They probably haven't figured that out yet, since this is still in the prototype stage.

EdV, from what I've seen in metal-to-plastics conversions in other assembly technologies, I'd agree with that statement.

Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
A new online manual that describes in detail the range of commercial technologies for joining automotive aluminum components is available free from the Aluminum Association.
