Using high-speed X-ray technology, researchers reportedly have been able to determine how laser power and speed affect the formation of keyholes,
or pockets produced during additive manufacturing (AM) via the laser
bed fusion process. As a laser travels across a bed of material to
create part layers during 3D printing, voids of various sizes and shapes
form, sometimes resulting in gas pockets that negatively affect part
density and ultimately, quality.
Conventional wisdom has held that powder material or laser strength were
to blame, but a team led by researchers from Carnegie Mellon University
and Argonne National Laboratory believe they have cracked the code,
providing insight on how pocket sizes can be predicted and minimized.
Larmour, CEO of Orbex, reveals Europe's most modern, environmentally
friendly and reusable launch vehicle. Of partnering with SLM Solutions
to 3D print the world's largest single-piece rocket engine Larmour stated, “This allows us to build reliably in a repeatable manner at a reduced cost."
Industries is a manufacturer of high performance vacuum debind and
sintering furnaces for the 3D Additive Manufacturing furnace market, as
well as units for Metal and Ceramic Injection Molding. Available with
either metal or graphite hot zones, these units can process all of the
most common metals including Fe-Ni, 316-L, 17-4PH, and Inconel powders
and feedstocks as well as a variety of other materials including
Titanium, tungsten carbide, tool steels, and superalloys. The new
Sintervac AM™ operates at pressures of 0-15 torr as well as positive
pressures of Argon, Nitrogen, or Forming Gas for increased flexibility
of processing binder-jetted parts, while the Workhorse AM™ is used for
the heat treat, annealing, and tempering of laser-sintered parts. For

Industrial N.V., a major manufacturer comprising such well-known brands
as Case IH and New Holland Agriculture, announced a company first: the 3D printing of spare parts.
The first spare components created via AM include four parts for use on
buses and agricultural equipment, made from plastic. Testing now
underway is expected to lead to production of metal spares, according to
a video series, Marc Saunders, director of AM applications for
Renishaw, discusses key factors that drive the success rate and
productivity of metal AM builds as well as some of the critical
guidelines that designers should follow to create production components
efficiently. This installment: AM supports.

is where the entire community convenes to share what’s new and solve
their toughest manufacturing challenges. See the latest 3D technologies
from 350+ exhibitors, learn real-world additive manufacturing solutions
from industry experts, and network with 6,000+ attendees.
Mexico is hot on AM, and getting hotter. On June 12-13, the Mexico Additive Manufacturing and 3D Printing Conference
takes over the Safi Valle Hotel in Monterrey, Mexico. Interact with
industry experts and learn about 3D printing equipment and materials,
and production applications in aerospace, automotive, medical and other
AMUG Conference provides a unique additive manufacturing (AM) training
and education experience. Designed to facilitate information exchange
between AM users, the conference brings together individuals of all
experience levels that wish to do more with AM. What makes the AMUG
Conference particularly unique is the openness of attendees and their
willingness to share. The AMUG Conference runs from March 31 to April 4,
2019. For information and links to registration, visit www.amug.com.
