Tackling Internal-Quality Concerns
Key to Bringing 3D Metal-Printed Parts Mainstream

That’s why researchers at Carnegie-Mellon University in Pittsburgh, PA, are busy at Argonne National Laboratory in Chicago peering into thin slices of 3D-printed titanium parts.

The group is examining defects in the printed metal that are invisible to the naked eye, according to Hanna Diorio-Toth’s article at www.phys.org. The tiny pores can increase susceptibility to breakage—not an option when such parts are slated for safety- and performance-critical applications such as jet engines.

As Diorio writes, “improving the internal structure of 3D-printed metal parts is one of the several challenges that need to be met in order for this manufacturing process to be adopted in a more mainstream way,” beyond prototypes. Part quality and quality-testing methods are big issues in the adolescent industry right now.

Direct-Metal-Transfer Process Brings Implant Benefits
The introduction of direct metal transfer (DMT), a 3D metal-printing process, to apply coatings to orthopaedic implants, has brought strength and porosity benefits that promote bone-tissue ingrowth and long-term implant stability. That’s the word from UK-based TLM Laser (www.tlm-laser.com), whose InssTek MPC printer used the DMT process to apply pure titanium in a thickness of 0.7 mm. An a comparative study, the machine’s output was measured against that of a titanium-plasma-spray (TPS) process. Results showed that the 3D metal printing process delivered an 83-percent improvement on porosity, a key attribute in the promotion of bone tissue ingrowth. Tensile stress showed a 17-percent improvement and sheer stress a 7-percent improvement.

Further improvements in economy come from the fact that the InssTek MPC is less expensive than most TPS machines. Also, the cycle times for the 3D coating process on the acetabular cups was between 12 and 18 min.—considerably faster than alternative technologies with a commensurate increase in productivity.

Aerospace Metal 3D Printing:
Materials, Machines and Methods

Metal 3D printing has become a game changer for aerospace OEMs, by drastically reducing the time and cost to develop prototypes and tooling, and powering through the development cycle. The thrust to print metal parts has spread quickly throughout the sector.

Pushing the Design Boundaries with Metal AM
Greater design freedom is recognized as one of the key benefits of using additive manufacturing (AM) for the final production of parts. Reducing the need for tooling and being able to more freely add and subtract material means that parts can be made with more geometric features than when manufacturing them with conventional processes, and with much greater complexity. This has been exploited in many ways, with value added to the product in one or more ways.

3D Printing: Feasibility is Getting Closer for Dies
Conventional metalforming techniques are very capital intensive due to expensive tooling. Selection of manufacturing processes, material and tooling for targeted volumes is critical for managing production costs. Here we present a sophisticated methodology to assess manufacturing strategies, review design for manufacture, and evaluate cost-benefit of reducing the investment in tooling with 3D metal printing.
