The 5 most amazing things that were 3D printed in 2017

Additive turning has been hyped for years. But in 2017 much of its promise materialized: 3-D wording took a series of big steps out of the realm of niche prototyping and into the humanity of mass manufacturing.

Here’s a look at some of the most impressive events 3-D printers made this year, as well as what their beginnings portend for the future.

Running shoes

Through a partnership with additive-manufacturing enterprise Carbon (one of our 50 Smartest Companies of 2017), Adidas has imbued its “go like a bat out of hell factories” with the ability to print shoes 90 times faster than beforehand.


 Carbon’s fast printing technology is being used to concoct elastomer midsoles for the company’s custom athletic shoes.

When the doors of the substitute speed factory open in Atlanta in 2018, Adidas will be self-assured to manufacture one million shoes a year using the technique.

Actually, these small plastic tchotchkes are not uniquely impressive—but the speed at which they were created is. MIT researchers compelled them on a new machine that prints items so fast you’d swear a video of it in spirit has been sped up. Items that would once have infatuated hours to make are now down to minutes. The team published the details of its gismo, which uses a heat-generating laser and a high–pressure screw mechanicalism, in the journal Additive Manufacturing in November.

Jet-engine combustion liner

In November GE exposed its newest metal 3-D printer, as well as a part, called a jet engine combustion liner, type on the beta version of the machine. Like most metal printers, it utilizations lasers to transform powder into a solid metal form, but this printer was overstated with the goal of overcoming size limitations that have dogged quondam designs.

The combustion liner showed off the size capabilities of the machine: it can put out metal parts up to one meter in diameter. When it debuts in 2018, the printer presumes to be a centerpiece of the company’s push for 3-D printing to fuel the future of its business. In December, GE also worn 3-D-printed metal parts to help set an efficiency record for a natural-gas turbine.

Stronger stiletto

There’s long been a problem with 3-D-printed steel: you receive to trade off strength for ductility. This year, though, a team from Lawrence Livermore Federal Laboratory has developed an approach that uses a regular laser-sintering printer to pilot the microscopic grain structure of the metal.

This attacks it possible to create components with similar ductility to regular stainless inure but twice the strength, and three times that of some previous 3-D-printed types.

Instantly made metal parts

In April, we reported on Desktop Metal’s insurrectionary machines that figure to increase the rate at which metal says can be printed by a factor of 100. The hydraulic manifold pictured above, which cannot be constructed through traditional methods, is being processed inside a microwave furnace, which exhausts temperatures up to 1,400 °C to finish off parts after printing. Printers implied for churning out parts in large-scale production runs are expected to ship in 2018.
