3D printers have been around for a while. They date back to 1983, when Chuck Hull of 3D Systems Corporation invented the first. Since that time, the technology has gone largely under the radar due to the elevated manufacturing costs. Other emerging technologies like smartphones and tablets have had much greater success – that is, until now. Back in 2002, any standard techie could tell you that at £20,000 per printer, it just wasn’t financially viable for most businesses. Yet, lately, this has decreased to a fraction of the previous price, so it is finally being considered to have legs in the manufacturing world.So how does it work exactly? 3D printing, or ‘additive manufacturing’, as it is also known, requires an initial computer design or a scan of the desired object. This is sliced into wafer-thin virtual layers by the computer, and these are then printed in sequence using melted plastic, creating a three-dimensional object. This means that literally any shape, however weird, wonderful or unique, can be printed as a solid object, in theory.Dr Phil Reeves, who is the managing director of an additive manufacturing company, claims that the ability to mass-personalize goods and produce individual products for individual consumers has opened up an incredible opportunity. He says that we have been living in the age of mass production, where everything is the same, but that we are now developing digital tools to make unique products designed by and for individuals. In this way, manufacturing has come full circle to before the Industrial Revolution, when the emphasis was on individual craft.In east London, Alice Taylor runs a doll-making business called MakieLab. Not so long ago, her dolls would probably have been cheaper to mass-produce abroad, but thanks to 3D printing, that’s no longer the case. She uses suppliers in London and Amsterdam to print the dolls, but all of the assembly is done at her office, and an employee even makes all of the clothes individually and by hand. Every doll is unique. For Alice, it’s cheaper to make dolls to order for her customers, rather than mass producing them and paying the manufacturing and transport costs.Alice’s business is not alone. We are seeing more and more businesses like hers focusing on personalized consumer goods. This has a knock-on benefit for the environment as well, since consumers are more likely to keep a product for longer if it has been tailor-made and holds particular sentimental value for them.Once the technology gets up to speed, what does the future hold for 3D printing? It seems that as soon as different materials can be used and can be combined with electronics, it will be possible to print not just a mobile phone cover (these are already being made by a limited number of start-up companies), but also a working phone. Richard Hague, Professor of Innovative Manufacturing at the University of Nottingham, is excited by 3D printing’s potential. He said that he was trying to move away from single material additive manufacturing, to manufacturing the whole product or system using different materials.3D printing is currently under close scrutiny, because it is still largely in development, but in the future it is thought that it could be used to produce lighter aircraft, spare parts for spacecraft and even working body parts. However, we might have to wait a little while to see if those plans actually come to fruition.

Choose the correct answersSchools are put under ______________ to buy the most up-to-date technology.
- A.
Age
- B.
Pressure
- C.
Scrutiny
Correct Answer
B. PressureExplanation
Schools are put under pressure to buy the most up-to-date technology because there is a constant demand for schools to keep up with advancements in technology in order to provide students with the best possible education. Additionally, schools may face pressure from parents, students, and the community to provide access to modern technology in the classroom. This pressure can come from the belief that technology enhances learning and prepares students for the future job market.Rate this question:

A 3D printer works by building up a series of layers until a solid object is formed.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A 3D printer works by using a process called additive manufacturing, where it builds an object layer by layer. It starts with a digital model of the object and then slices it into thin cross-sectional layers. The printer then deposits material, such as plastic or metal, layer by layer, following the instructions from the digital model. This process continues until the entire object is formed. Therefore, the statement "A 3D printer works by building up a series of layers until a solid object is formed" is true.Rate this question:
