NASA recently tested a rocket engine 75% composed of 3D printed DMLS parts. “This new manufacturing process really opened the design space and allowed for part geometries that would be impossible with traditional machining or casting methods,” said NASA designer David Eddleman.

Because of the highly complex geometries and its capabilities in exotic metals like Inconel and Titanium, Direct Metal Laser Sintering (DMLS), 3D metal printing, is not only widely used for research, but is considered a cost-efficient manufacturing measure. Aerojet reports that its rocket made entirely from 3-D-printed components reduced manufacturing costs by 65 percent.

DMLS uses a 3D model to direct its lasers to fuse material together layer by layer in optimized micro slices. There is no waste or scrap metal, thereby reducing the cost of printing in exotic metals like Titanium and Inconel by 50-70%.

Thrusters are one of the most successful 3D metal manufacturing applications. DMLS allows rocket scientists to eliminate potential leaks or failure points by integrating and printing multiple part assemblies as one seamless part. “Aerojet Rocketdyne continues to push the envelope with both the development and application of 3-D printed technologies, and this successful test opens a new paradigm of possibilities that is not constrained by the limits of traditional manufacturing techniques,” said Aerojet Rocketdyne’s Vice President of  Space Advanced Programs Julie Van Kleeck.  Read more at http://www.spaceflightinsider.com/missions/commercial/3d-printed-rocket-propulsion-system-satellites-successfully-test-fired/#CigcAF5bh8z049Vk.99

Micro channels and organic flow patterns are also achievable with DMLS. 3D metal printing is a disruptive technology that facilitates efficiencies and custom designs on demand, both of which are desirable for satellite and rocket thruster needs. NASA, ESA and many private companies have successfully tested thrusters in the past 2 years. The thruster that NASA Marshall fired Fall 2015 is almost made up entirely of 3D-printed parts, the only piece that’s not 3D printed is the liquid oxygen pump.

Satellites

3D Metal Printed SatellitesThe U.S. is scheduled to begin construction on a radar array in 2015 which will track some 200,000 objects orbiting the planet. DMLS allows weight reduction by nearly 70% while maintaining the same part strength and integrity. Solid components can be latticed in custom honeycomb patterns for optimized weight reduction and part function. An article on 3ders.org comments, “Countless (NASA) greenlighted projects for satellites and the upcoming mission to Mars have included metal 3D printing in one way or another, often with the help of external partners.” i3D MFG™ is proud to supply NASA and other partners with leading edge 3D metal printed components.

Robotics

3D Metal Printed RoboticsRobotic components are well suited to DMLS because of the complexity, customization and durability requirements. Lighter weight, low volume custom parts are cost effectively 3D printed in titanium, Inconel, maraging (tool) steel and stainless steel. Designers and engineers can use exotic metals previously too expensive to upgrade Aluminum parts while improving or maintain costs and weights.

In a professional context it often happens that private or corporate clients corder a publication to be made and presented with the actual content still not being ready. Think of a news blog that’s filled with content hourly on the day of going live. However, reviewers tend to be distracted by comprehensible content, say, a random text copied from a newspaper or the internet.

The are likely to focus on the text, disregarding the layout and its elements. Besides, random text risks to be unintendedly humorous or offensive, an unacceptable risk in corporate environments. Lorem ipsum and its many variants have been employed since the early 1960ies, and quite likely since the sixteenth century.

Aluminum (Al)

AlSi12 isn our most common DMLS Aluminum powder and is perfect for projects with good thermal and low weight considerations.  It is an optimal metal for parts with thin walls and complex geometries.

Titanium (Ti)

Ti64 is the standard DMLS powder which is well suited for Medical, Aerospace, Firearms, Energy and Automotive projects requiring corrosion resistance, strength, weight reduction and biocompatibility.

Stainless Steels

IN718 is a DMLS nickel; A Chromium alloy with superior heat resistance and typical heat treatment hardness of 40-47 HRC (370-450HB).  Rocket, space, aerospace, firearms, energy, and automotive industries rely on Inconel.

Maraging Steel

Maraging (Tool) Steel (MS1) & Stainless Steel (PH1).  Our steel powders have excellent strength and mechanical properties.  MS1 is a pre-alloyed, ultra-high strength steel powder most commonly used for tooling applications.

Inconel (IN718)

IN718 is a DMLS nickel; A Chromium alloy with superior heat resistance and typical heat treatment hardness of 40-47 HRC (370-450HB).  Rocket, space, aerospace, firearms, energy, and automotive industries rely on Inconel.

Custom Powders
