3D printing – a revolution on the horizon?

What an achievement, this is my (Christopher Roberts’s) 100th post on Technology Bloggers!

Thank you everyone for your support, I love writing here, and that is because of the fantastic community we have created 🙂

3D printers have been around for around 20 years now, however it is only recently that they have really started to show their true potential, both in industrial and now even domestic settings.

Thanks to the recent advancements in 3D printing, CAD designs can be constructed into physical prototypes (and in some cases now even final products) by 3D printers. 3D printers have the potential to revolutionise the way we live our lives, due the variety of possibilities they unlock. 3D printing could revolutionise architecture, product design, industry, education, and so much more!

What exactly is 3D printing?

Most people have access to a normal printer, be it black and white or colour, ink jet or laser. Those sorts of printers however, only work in 2 dimensions, they can print content in the dimension that is left to right, and the dimension that is forward to back. 3D printing adds in another dimension, up and down. Therefore 3D printing means that you can print in height, length and breadth.

Why is 3D printing important?

Some critics have speculated that 3D printing will be as big, if not a bigger revolution to industry, and the way we live our lives, than the internet was. The internet has opened up so many opportunities, but it is believed that 3D printing, could possibly open up even more!

For architects, it will mean that within minutes, they will be able to print on screen prototypes of buildings, so they have a tangible product to show the customer, in virtually no time at all!

For retail, 3D printing could mean that shops hold no stock, and products (less complex ones at first, but branching out in the future) could be made to order, on site! No longer would shops be out of stock, so long as they have material to print on, they can make new products, there and then.

For healthcare, the new printing capabilities will mean that body part replacements can be accurately measured, designed, and then printed. Yeah, printed bones! Just last month, it was publicised that the first 3D printed jaw had transplanted onto the face of a woman from the Netherlands. The jaw was matched to the shape of the patient’s original jaw, using CAD modelling, and then layers of titanium powder were melted into shape by the powerful lasers that make up the 3D printer.

How do 3D printers work?

Different 3D printers work in different ways. Some work by building the object slowly, layer upon layer in an upwards direction, whilst others work by cutting down into a material. The titanium jaw example from above was built by building upwards creating layers upon layers of material, from titanium powder fused together by laser.

What materials can be ‘printed’ on?

Currently you can ‘print’ on plastics, metals, ceramics, glass, and even certain malleable foods (such as sugars and chocolate). In the future that selection of materials is likely to be expanded, and some even believe that we could grow human bone, and then 3D print replacements – that is still a way off at the moment though!

Could you get a 3D printer?

Many firms are looking to capitalise on the decreasing cost of 3D printers, so much so that some companies are now offering (simpler) domestic versions for home use!

One firm selling 3D printers to the domestic market is the New York company MakerBot. Makerbot are offering a basic 3D printer, which can create plasic objects using CAD software, for $1,749 (around £1,100).

MakerBot's 3D PrinterIn an interview with the BBC, MakerBot’s chief executive Bre Pettis, claimed that the printer is “a machine that makes you anything you need” which is “handy in an apocalypse or just handy for making shower curtain rings and bathtub plugs.”

Mr Pettis also said he hoped to get his printers “into the hands of the next generation because kids these days are going to have to learn digital design so they can solve the problems of tomorrow”.

Another company, (called 3D systems) is offering its ‘Cube’ 3D printers at a similar price to Makerbot, marketing it as a tool to express your creativity. The company is currently working on an app that will allow users to use the Microsoft’s Kinect motion sensor to create objects, simply by moving their hands through the air!

3D printing is bringing to the global market a fast and increasingly affordable way of turning ideas into reality. No longer will the joys of flexible design be limited to those with CAD jobs and the luxury of a prototype department. There is now a big incentive for people to learn CAD techniques and how to use CAD software. Many countries are now investing in 3D printing technologies, as they can see the potential; IT jobs in the UK and abroad are likely to see big benefits from this.

3D printing is real, and it is here.

So, what do you think about 3D printing, will it revolutionise the way we live our lives – even as much as the internet did? Or do you think that it is a waste of resources, and that it will never really be cost effective enough to be used on a mass scale?

Why does superfast broadband matter?

Technology Blogger has had many articles about broadband speeds, superfast internet connections, and how the general trend is that global internet speeds are on the rise, but the question is, why is that important? Why do superfast speeds matter?

Download and Upload

There are two types of internet speed, your download speed, and your upload speed. Your download speed is how fast you can receive data from the internet – how fast you can stream media, receive emails, load websites etc. Your upload speed refers to how fast you can send information to the internet – how fast you can send emails, upload media, update your status etc.

When people talk about broadband speeds on the rise, they are usually referring to download speeds, as most of us get a lot more from the internet than we upload. Both upload and download speeds are on the rise, but upload speeds are usually only around 10% of download speeds – depending upon your location.


So superfast broadband means that we can do things faster, we can download and upload content quicker than we used to be able to. But that does that mean?

More Going On

Faster internet speeds mean that you can be doing more things at once on the internet, with less lag or jitter. You can be on an online game, whilst streaming the radio, and in the background sending emails, all at the same time! You can have more internet hungry applications running at the same time, and the speed of your activities (providing you have adequate processing power) should be the same as if you just had one activity going on.

Improved Internet Call Quality

Faster internet speeds will allow for smother internet calling, with less lag and better quality. You will be able to chat with friend across the globe and stage a conversation as though they were there in the room with you. VoIP will be significantly improved, as faster speeds meant that the media you are sending out is of higher quality, and the stream you are receiving is better too.

Such improvements could significantly benefit businesses, as VoIP can significantly lower the cost of holding meetings with fellow colleges based in different locations, thanks to better, more affordable online conference calling.

Furthermore, improvements in internet call quality can make remote working more viable, meaning that employees can spend more time working and less time commuting, thanks to them being connected all the time. This can save time, money and office space, as more employees are able to work off-site.

Improvements in Healthcare and Education

As Rashed suggested in his recent article (Five changes in video conferencing for the next decade) improvements in internet calls could lead to an improvement in the provision of telemedicine, meaning that the best doctors can help patients from across the world.

There is also similar potential for education. The best lecturers and teachers will be able to educate far greater numbers of individuals from across the world, thanks to faster broadband speeds. Improvements in such technology could be very beneficial for those living in isolated communities.

Cloud Computing Becomes More Viable

Cloud computing has huge potential to cut costs, improve efficiency and improve data security, and superfast broadband makes it more viable! With faster broadband, more and bigger files can be stored in the cloud, meaning that files are less likely to be lost if one device fails, and are more likely to be accessible from any location.

Media Streaming

Streaming media from across the internet is smother, faster and more seamless with faster internet connections. You can watch online videos with less buffering, or even in high definition.

Furthermore, internet TV and other similar services become more viable than ever before. In the last quarter of 2011, Virgin Media reported profits of £48 million, which it is believed is mainly down to faster broadband speeds encouraging more users to user its TV and internet services.

More People Online

Every day thousands of new people around the world make the leap and go online. For every extra person on the internet demanding resources, the whole system slows down a little. However with superfast broadband, more people can be online with less of an effect on speeds. In large offices, more employees can be connected, with less of an effect on the speeds received. This is also true in households, more people can be downloading media, whilst it not affecting others on online games.

Your Speed

Superfast broadband is very important and is revolutionising the way we do business and live our lives. The question is, how fast is your broadband speed? Are you likely to benefit from the things I mentioned above, or do you need to think about switching provider? Try testing your broadband speed and comparing it to what you are paying for; could you be getting a better deal elsewhere?
