MIT figured out how to 3D print using glass instead of plastic
Researchers at the Massachusetts Institute of Technology unveiled a new 3D printing method on Friday that employs transparent glass as precursor instead of plastic. The method, called 3DGP, works basically the same way that conventional 3D printing does though the team found that they could modulate the light transmission, reflection and refraction qualities by precisely varying the thickness of the print.

Chongqing home to ‘most illegal building in the air’
A 66-meter-high balcony in Chongqing has Chinese netizens divided. The balcony was originally designed to connect two units in a residential building together. But it has since been illegally transformed into a personal home, according to news report by Youth.cn.
The balcony – located between the 21st and 22nd floors of the building – has been reconstructed with walls and roofing by one of the building’s property owners.
The new domicile is made of glass and steel, and has an area of about 6 square meters. It’s been called “the most illegal building in the air” by Chongqing residents, the report said.
While some netizens are showing their concern over safety issues, others are saying the balcony is a public area – and if not, should be subject to administrative procedures.
“This cannot be defined as illegal construction. They just added a roof,” Weibo user @fuyu posted.
“This is definitely not designed to be a load-bearing structure. Aren’t they afraid of it falling down some day?” wrote @doudouEric.
“This kind of suspended balcony shouldn’t have been built at all,” posted @zashidegongchengshi.

Giant Chinese 3D printer builds 10 houses in just 1 day
A Chinese company is using 3D-printed blocks to build cheap and quickly assembled houses as a possible solution to the urgent problem of modernizing housing conditions in Chinese villages. The blocks are made from a mixture of sand, concrete and glass fiber, materials processed from common construction waste, which is pumped layer after layer through the top of a 6.6-meter-tall, 32-meter-long industrial printer.

Sheffield university is investing a lot of money in a new building for the faculty. I’m excited because it’s estimated to be done by autumn 2015 so I’ll get to use it
A Good Read
If you are someone interested in the design process behind a project some great case studies to read are: Waterloo Station in London and The Eden Project in Cornwall. Both projects were worked on by Nicholas Grimshaw Architects and Anthony Hunt Associates and are excellent examples of how engineers approach problems in a design brief. (I have tried to find links to decent online versions but haven't been able to as of yet. I will edit this post if I do)
Joint Architecture Bridge Project
In early march engineers from Civil and Structural engineering were put into groups with second year architects. In these groups we had the task of redesigning a footbridge near Sheffield train station. The train station is making plans to start shutting their own footbridge from the apartments to the east. The current bridge, as you can see below, is not particularly nice looking or safe for that matter, hence the need for a new one.
The primary reason for having this joint project was to give engineering and architecture students the chance to work together and learn how the other approached a design brief. We were told at the beginning that the bridge had to be aesthetically pleasing (the architect's job), and also be able to hold an 8kg load whilst being as light weight as possible (the engineers job).
At the beginning of the design process we went over possible types of bridge e.g. Suspension, Cable Stay, Arch, Tubular. The architects decided they would like a cable stay bridge and the engineers agreed this could be made stable.
To optimise the design from an engineering stand point we gave the bottom of the bridge deck a reinforcing triangular truss and the piers were made wider and trussed in the plane which they would be bending. The finished product is what you see below.
On test day our bridge failed after 7.5kg which only gave us a minor penalty and the bridge was light which left us with another small penalty. The architects explained their design choices and their concept and we managed to score quite highly for a concept score.
Over all our design came 10th of 33 groups. However I believe I have found a new respect for architects and believe the experience has helped me approach design briefs differently.

This may not be Civil or Structural engineering but it has some potentially awesome aplications
In this edition of The Future, a private firm in China called WinSun has used its technology to build huge 3D printers that in turn print even huger fully-functioning houses. Their printers can manufacturer 10 in a day. Let's assess.
Global Engineering Challenge
Global Engineering Challenge (GEC) is an event set up by 'Engineers Without Borders' (EWB). At the university of Sheffield the event took place over a week in mid January with all students from the engineering faculty getting involved.
Students were split into groups which consisted of people with a wide range of disciplines. These groups were put into groups called hubs which they would have presentations with and research with in the week to come. Each group was given a problem that EWB had identified as a problem in either Uganda or southern Indonesia.
The group which I was part of consisted of a chemical engineer, an aerospace engineer, a mechanical engineer, a robotics engineer and myself, a civil engineer. We had the problem of providing a new water filtration/sanitisation system for a village in a developing country seen as they were wasting money on boiling the water or buying it bottled.
Throughout the week we researched affordable methods of water sanitisation and by the end came up with a combination of a Bio-sand filter and a container which allows UV radiation from the sun to kill bacteria. Although the design is not big on ingenuity, our report and accompanying presentation won our group the 'Best overall Solution' for our hub.
