COVER STORY
14 3D Metal Printing Revving Up the Auto Industry
Formula 1 teams lead the way in developing creative 3D metal-printing applications to shave weight while improving performance. And at least one innovative manufacturer has developed a space-frame concept using 3D-printed metal nodes. What’s coming next?

Need to Know About 3DMP
Become proficient in metal additive manufacturing and you’ll gain the ability to create parts with greater adherence to design intent, while mastering low-volume production and prototyping and learning to work with a variety of materials. But know that there’s much more to developing a core competency in 3D metal printing than simply pressing a button.
22 Titanium Taking Off
Machining titanium into aerospace parts can create a buy-to-fly ratio upwards of 10 to 1, as machine shops turn expensive metal into chips. Often 3D metal printing makes more sense, but only as long as titanium-powder producers can meet the growing demand for powder that’s fit for metal printing.
26 AddandSubtractAllinOne
Where the worlds of additive and subtractive manufacturing meet, there’s a whole lot going on. New machines offer the advantages of both processes, and bring a new set of capabilities.
32 Spotlight on Additive Manufacturing at IMTS
More than a dozen suppliers of additive-manufacturing technology will inhabit a new Additive Manufacturing pavilion at this year’s edition of IMTS. Also on tap: a 1.5-day additive-manufacturing technical conference.

About the Cover
The weight-reduction and performance-enhancing capabilities presented by 3D metal printing are simply too enticing for the automotive industry to ignore. The automotive production applications for 3D metal printing primarily reside within the motor-sports arena. Shown is the BMW Motorsports model Z4 GT3, introduced in 2010 and featuring a one-piece 3D-printed aluminum water-pump wheel. BMW has fabricated more than 500 of the wheels using the selective laser melting process to build up 0.05-in.-thick layers of aluminum powder.
