Boeing has invested in Digital Alloys Inc., a Burlington, Massachusetts-based company developing high-speed, multi-metal additive manufacturing (AM) systems that produce 3D-printed parts for aerospace and production applications.

Digital Alloys’ Joule Printing technology rapidly combines multiple metals into each part, enhancing thermal, electrical, magnetic, and mechanical properties. The process allows metals such as titanium and high-temperature alloys to be 3D-printed for parts that could be used on Boeing products.

“Our investment in Digital Alloys will help Boeing produce metal structural aerospace parts faster and at higher volume than before,” says Brian Schettler, managing director of Boeing HorizonX Ventures. “By investing in companies with emerging additive manufacturing technologies, we aim to strengthen Boeing’s expertise and help accelerate the design and manufacture of 3D-printed parts to transform production systems and products.”;

3D-hybrid machining center

The automatic tool change solution for systematic 3D hybrid manufacturing is incorporated into the H12 double column machining center. The hybridized machine boasts X,Y, and Z travels of 53"x 37"x 23"or about 26ft3 of printing and finish machining volume. It offers nearly 100fpm travel speed and a high-deposition rate, wire-arc tool.

The pairing provides machined internal features and complete processing in one work offset. Increased freedom of complexity, lower costs in material and processing time, and novel materials combine with additional capability, repair, and salvage of large parts. Repairing and filling worn surfaces with material stronger than the original, followed with final machining, can eliminate downtime and extra costs.;

3D printer for carbon-filled nylon

The Fortus 380mc Carbon Fiber Edition (CFE) additive manufacturing (AM) system is dedicated to carbon-fiber-filled Nylon 12, incorporating 35% chopped carbon fiber by weight and a high stiffness-to-weight ratio. Nylon 12CF is up to 4X stronger in the X- and Y-axis, and it will maintain its mechanical properties at a 40% higher temperature.

Parts don’t exhibit appreciable warpage or shrinkage and will hold to tight tolerances.

Parts are built in 0.010" (0.254mm) layer thickness. The system is also compatible with ASA thermoplastic, which can build in 0.010" or 0.005" (0.254mm or 0.127mm) layer thicknesses. The 3D printer’s build chamber offers water-soluble support material removal, eliminating the need for manual labor to remove supports for fine and intricate geometries.

3D filament system

The ZSE-3D twin screw extrusion system facilitates development and production of 3D filaments from a co-rotating or counter-rotating twin screw extruder. Direct extrusion of raw materials facilitates rapid product sampling, and results in one-less heat and shear history compared to two-step processes, benefiting heat and shear-sensitive formulations.

Formulations can be modified on the fly for rapid sampling of filaments with different formulation percentages. A sample can be produced every 10 minutes. The system is rated for 425°C operation and can be configured for water-soluble and high-temperature engineering polymers.

Additive manufacturing demostrations available

Renishaw has opened an additive manufacturing demonstration center in Newbury Park, California. Working in collaboration with Ibex Engineering, the demonstration center is within Ibex’s headquarters and allows visitors to explore, interact with, and use Renishaw’s metal additive manufacturing (AM) systems.

The center can print high-precision titanium (Ti64Al4V) parts on Renishaw’s RenAM 500 series of laser-powder-bed- fusion AM systems that have automatic powder sieving and recirculation within the compact system, reducing the need for manual handling and exposure to materials.

Wet downdraft, heat treatment, support, machining, inspection, and part removal equipment work in concert with the AM system to ensure parts are printed to specifications.

Also available at the site is InfiniAM Central software with AM production reporting functionality and QuantAM build preparation software, allowing users to work through the development of an AM machine build file, including material parameter development.;

CAD file viewer

K-Display View software multi-platform program for CAD file viewing is built on the universal CAD architecture of the Kubotek Kosmos 3D framework.

Available on Windows, Mac and Linux, and the iOS and Android mobile platforms, the software replaces the Kubotek Spectrum multi-CAD viewer software. It provides a streamlined user interface and faster operation.

No additional CAD software or Internet connection is required, enabling manufacturing, sales, support, and service departments read-only versions of files from commonly used CAD programs including SolidWorks, AutoCAD, PTC Creo, Siemens NX, CATIA V5/V4, and neutral formats such as IGES, STEP, Parasolid X_T, ACIS SAT, and STL.

AGS joins America Makes

AGS Additive Manufacturing has joined America Makes, the nation’s collaborative partner in additive manufacturing (AM) and 3D printing technology research, discovery, creation, and innovation.

“We look forward to collaborating with other leaders in the AM field,” says Kevin Goold, AGS 3D printing manager. “Being a third generation, veteran-owned company, we appreciate the pride this impressive group has in keeping America at the forefront of additive manufacturing.”

AGS Additive Manufacturing, based in Fort Worth, Texas, specializes in 3D printing metals such as steel, aluminum, titanium, cobalt chrome, and Inconel.
