X-rays reveal more about 3D-printed metal parts as they are being made, and how to improve them
Metal 3D printing could revolutionize manufacturing, but concerns over part quality and certification has kept many industries from jumping into the technology with both feet. From their perspective, the quality and certificate are critical, and essential for parts destined for automotive and aerospace applications.
To improve metal 3D-printed parts, researchers at Lawrence Livermore National Laboratory (LLNL) are examining the complex mechanisms that drive defects and limit part quality. They have also teamed with scientists at the SLAC National Accelerator Laboratory and Ames Laboratory to better understand 3D printing, looking into what leads to defects and how those flaws might be avoided.
Today marks the start of US trade tariffs on goods valued at $34 billion worth of imports from China. A list published by the Office of the United States Trade Representative (USTR) details the 818 tariff lines that will be subject to an additional 25% in duty.
China has responded with additional import taxes on US goods valued at a similar amount. 3D Printing Industry contacted resellers, manufacturers and other 3D printing insiders around the world for their thoughts about how the “the biggest trade war in economic history” will impact additive manufacturing.
So are the trade tariffs a threat, opportunity or a distraction?
From Freshfields Bruckhaus Deringer LLP:
On 3 July 2018, the European Parliament adopted a resolution entitled ‘Three-dimensional printing: a challenge in the fields of intellectual property rights and civil liability’.
The resolution starts by pointing out that 3D printing – also known as additive manufacturing – could be of great benefit to the European economy.
But the document mainly looks at the legal issues the technology raises. For example, it says more public awareness is needed to protect IP rights relating to 3D printing and calls on the European Commission to consider issues around civil liability. It even suggests the Commission could set up a specific liability regime.
According to the Parliament, the EU may have to adopt new, and amend existing, laws to take account of 3D printing. With the report claiming that Europe can play a leading role in additive manufacturing, it will be interesting to see how quickly the Commission moves to tackle the issues raised.
In recent years 3D printing has delivered several exciting developments, from organs to race cars. Now, it’s adding houses to its repertoire.
Dutch construction company Van Wijnen has partnered with the Eindhoven University of Technology to deliver five fully habitable, 3D-printed houses by 2019.
According Van Wijnen Manager Rudy van Gurp, Project Milestone (as it’s called) was in part a response to the shortage of people willing to take part in the laborious construction process.
“We need a technical revolution in the constructing area to respond to the shortage of skilled bricklayers in the Netherlands and all over the world,” he said.
