Low-Oxygen Ti Powder from 6K Additive
6K Additive announced the availability of ultra-low-oxygen Ti-6AI-4V in the 500 to 700-ppm range, with the company’s ability to deliver this at production scale surpassing what is currently available, according to company officials.
The low-oxygen Ti-6AI-4V reportedly provides a high-quality material that enables users to increase output in their AM machines without sacrificing quality. It effectively lowers users’ overall cost for

titanium parts with powder that stays with-in printable specification longer, note 6K Additive officials.
In addition to low-oxygen Ti-6AI-4V, 6K Additive produces a full suite of AM powders including Ni718, Ni625, stainless steel316/17-4,copper18150,GRCOP,and refractory powders including tungsten, tantalum and rhenium.

H13 Tool-Steel Powder
Now Available for
Digital Metal Binder Jet Printers
Digital Metal announced availability of H13 metal powder, to be known as DM H13, for all of its metal binder jet printers. The hot-work tool steel can maintain its strength and hardness when exposed to high temperatures, and exhibits good resistance to thermal fatigue. As an abra- sion-resistant metal, H13 commonly is found in forming tools such as extrusion dies and injection molds.
Adding this certified metal to the Dig- ital Metal material library will allow print-

Dyndrite, PostProcess Team for Post-Processing Automation
Dyndrite and PostProcess Technologies announced a working relationship to deliver end-to-end CAD to post-process- ing automation via the Dyndrite Appli- cation Development Toolkit (ADK). The companies aim to simplify the ability for customers to deliver lights-out-manufac- turing recipes that optimize part post- processing.
“Dyndrite and PostProcess share a sim- ilar vision that production of AM parts will not scale unless the entire process, from design to finished part, is digitized and automated,” says Melissa Hanson, PostProcess Technologies chief marketing officer. Our work together will ensure that users of the software will be able to build end-to-end digital manufacturing solu- tions that deliver from native CAD to fin- ished, customer-ready parts.”
Currently, post-processing for 3D- printed parts is encumbered by excessive manual labor, part breakage and sustain- ability challenges, explain Dyndrite offi- cials. Additionally, they note, existing methods often expose operators to loose
powder, resulting in workplace safety haz- ards. These manual and dangerous processes, company officials continue, limit the ability to scale as customers are unable to provide closed-loop feedback for the complete AM workflow, or support end-to-end digitalization.
The Dyndrite ADK software and Post- Process solutions are designed to support and be compatible with a number of 3D- printing technologies.
“PostProcess Technologies has pio- neered the use of build recipes as the starting point for end-to-end automation of the manufacturing process in AM,” said Harshil Goel, CEO, Dyndrite. “We’re ecstat- ic to work with the PostProcess team to advance this capability within the market and deliver new capabilities and lights- out-manufacturing solutions to customers globally.”

Turnkey Solution for Automated Ti Compressor-Blade MRO
Optomec Inc. and Acme Mfg. have announced a partnership whereby the two will produce a fully automated work- cell initially optimized for repairing avia- tion compressor blades made of titanium. The turnkey workcell, reportedly a first, is the product of a 2-yr. collaboration between the companies working with input from commercial maintenance, repair and overhaul (MRO), and U.S. Dept. of Defense repair centers for aircraft engines.
The automated workcell features a repair capacity of 85,000 titanium com- pressor blades/yr. and provides a com- pelling ROI when compared to tradi- tional CNC machines and manual gas-tungsten-arc welding. Technologies used in the automated workcell are commercially available today and have been certified by civil-aviation author- ities worldwide, report officials from each company.
