Metals 3D printing: Power of laser melting allows new materials control on a micro level

Using an Arcam electron beam melting system researchers say they can control the variations in crystallographic orientation in a nickel-based alloy

While 3D printed metals are still metals, there’s a structural difference between them and the stuff you get cast in the traditional sense, which is still worrying some people about part strength and consistency.

Researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) have demonstrated an additive manufacturing method to control the structure and properties of metal components with precision that not only matches conventional manufacturing processes, but goes even further.

ORNL researchers have demonstrated the ability to precisely control the structure and properties of 3D printed metal parts on a micro level during formation.

A team from University of Wales TSD Swansea are looking to kite surf across the Bristol Channel

This weekend you’ve probably a friend, relative or colleague doing something, somewhere for a charity - a noble deed, some exhausting act, or something simply ‘a bit daft’.

We’re a society that thrives on both pushing ourselves, and contributing to helping others less fortunate, which is why the task set by a group from University of Wales TSD Swansea’s product design course is so eye catching.

Harnessing the power of both sea and wind, five kite-surfers will attempt to cross the 33 mile Bristol Channel in a world’s first attempt - To put this into context, the English Channel (Dover-Calais) is a mere 21 miles.

One of this year’s concepts includes Future Hunter-Gatherer, which turns shopping into a game by allowing users to virtually hunt for their dinner

Ultra light jellyfish air cleansers; virtual hunting for groceries and an instant bath towel cleanser are some of the futuristic concepts that make this year’s Electrolux Design Lab 2014 shortlist.

Established in 2003, the competition is a global design competition open to undergraduate and graduate design students who are invited to present innovative ideas for future households, with this year’s brief to offer solutions to Culinary Enjoyment, Fabric Care and Air Purification in the future home environments.

Over 1,700 submissions were received this year, which have now been whittled down to six finalists, with the overall winner announced on 12 November 2014.

Aerospace: New fan blade design could mean 25% less fuel for Rolls Royce engines

The test flight is another step on the path towards entering service in 2020

The Rolls-Royce composite carbon/titanium (CTi) fan blade for its Advance and UltraFan eco engine designs has taken to the skies for the first time.

The lighter fan blades retain aerodynamic performance, which when combined with a composite engine casing reduces weight by up to 1,500lb per aircraft, the equivalent of carrying seven more passengers at no cost.

The Advance engine design will offer at least 20 per cent less fuel burn and CO₂ emissions than the first generation of Rolls-Royce Trent engine and could be ready for entry into service from 2020.
