The 2 Food 3D Printers you Absolutely Need in your Kitchen

Posted by Andreas Christodoulou

Description :

Have you ever watched an episode of Star Trek: The Next Generation where they used a Replicator to make something out of thin air? Have you ever thought it would be cool to have that technology, but never thought that it would be achieved in your lifetime? 3D printers have made this a possibility and bridged the gap between reality and science fiction. There’s even a few build it yourself and DIY printers that are on the market as well. 

Transforming the Food Industry

In terms of Food 3D Printers for consumers, there are plenty of options available. Right now the technology isn’t as advanced as what was shown on Star Trek, but this is just the early stages. 

 There’s even been talk of bioprinting as an available option; this is the ability to print organic foods like a pear or an apple. The printer “ink” consists of 3 main components found in all foods: carbohydrates, fats and proteins. The raw ingredients are loaded into the printer, along with the appropriate ratios of food components; hit print and away you go. There have even been successful attempts at printing meat. The texture isn’t quite there yet but the taste is supposedly spot on. 

The two main hurdles faced by companies at the moment, is the texture/consistency of the food, and cooking the food while it’s being printed. If it’s a hamburger you’re looking for, yes you can have one printed. Just don’t be too surprised when the end result doesn’t look exactly like the burgers you’re used to.

The taste of the food seems to be the easiest to recreate. As long as you know the correct ingredients, your food should taste the same as regular food. The only obvious difference is how the food is put together.

Another reason that home and commercial 3D printers are having a hard time gaining popularity is due to the cost. Ironically it’s the industrial 3D printers that wind up being cheaper and this is because industrial machines are usually made with the purpose of printing only one part. Commercial machines have to be way more versatile; with more customization comes a larger price tag. It is still proving to be a challenge to fit the technology into a desk sized unit. Until companies can streamline and simplify the production, the cost is going to remain high. Creative Machines Lab is still developing printable muscle tissue. This will make it possible to reproduce more “real life” textures when printing foods like meat or fish. Don’t worry though, with the everyday advances in technology a cheaper and better performing printer will be on the market in no time.

Food 3D Printing is an extremely new concept with a range of potential benefits. Let's bring to the kitchen 2 very cool tools:

1. Foodini

 Foodini is made by a company called Natural Machines and prints mainly appetizers and entrees (burgers, pies, cookies and more). If you hate cooking, Foodini will save you some time.

Here is a brief intro. Check out the beta and pre-production model in action:

2. ChefJet 

ChefJet is the other Food 3D Printer on the market made by a company called 3D Systems and its focus is mainly desserts (cakes, candies, just to name a few). However, it needs to be more developed.

See it at work:

 Both are still being tested and perfected, and both are on the pricey side. The Foodini will set you back about $1,400 and the ChefJet can $5,000-$10,000, depending on if you want the single or multi-color machine. As of right now the Foodini is the only over-the-counter option. ChefJet has more testing to complete before they can offer a consumer-ready version of their machine.

Conclusion

Companies are not entirely sure how the general public will react to the idea of this new technology. People are scared of change. The same thing happened when the microwave first came out. At first everyone thought that it poisoned the food. Fast forward to today, and it is nearly impossible to find a house without one.

Natural Machines is the first to point out that they are not on a quest to take all the work out of cooking. Instead they want to eliminate the time-consuming preparation that discourages people from wanting to cook in the first place. They also argue that the machines promote healthier eating because they require fresh ingredients to be prepared before the printing.

Despite the reason, this technology puts the human race one step closer towards the Jetsons and we as people need to ask ourselves; should we be doing this? The smartphone was supposed to revolutionize the way we communicate but ironically it’s made us more anti social. Will 3D food printers make us want to cook more, or simply be another unnecessary convenience? Like it or not the future is at our doorstep and only time will tell what this new technology has in store for us.

The Future Is Now: Self-Healing Phones Hit the Market

Posted by Andreas Christodoulou

Description :

Self-Healing phones? I can't resist. Impressive and Awesome! 😮

According to SquareTrade, 25.6 percent of iPhone owners reported failure within the first two years with 18.1 percent caused from accidental damage. Another 7.5 percent of failures were caused from hardware malfunction. 

But, what if that dismal number could be slashed by new cell phones that could heal themselves? It may sound like science fiction, but self-healing phones are already making their way to the marketplace.

Biomimicry Technology

How can a phone heal itself without any human intervention? Well, engineers at the University of Pittsburgh are experimenting with biomimicry, or materials modeled after the human body. Think about when we get a cut. We get a scab, and it heals with little effort. Now, self-healing polymers can mimic that function and repair themselves.

Cell phones repair themselves by restoring their initial molecular structure. While a phone currently can’t repair itself after being run over by a truck, flattened and destroyed, it is possible for it to heal broken circuits and scratches. This could mean less consumer consumption and waste as cell phones become more impervious to damage.

Self-Healing Circuits

Scientists at the University of Illinois are developing a system of capsules inserted along the phone's circuits and filled with liquid metal. If the circuit is broken, the liquid is released to restore its connection and return the electrical flow. This could mean that cell phone users would never even know their phone broke before its fixed and working again. It also could avoid going in for diagnostic testing because the self-healing circuits would figure it out on their own.

Self-Healing Scratches

While we wait for self-healing circuits to hit the market, there is a phone ready for public use. The LG G Flex comes with a curved, OLED display that can actually bend for a limited period of time. This helps keep the screen and phone bend instead of cracking upon impact.

The phone also has a self-healing coat of paint that can withstand wear and tear and heal itself after piercings by sharp objects like keys or a blade. This also makes it easier to grip while it heals itself from scratches.

Functionality

So, we know the LG G Flex can bend and heal itself to a certain extent. But how is its overall user functionality? The phone's large, 6-inch HD curved screen gives it a distinctively cinematic experience. Its contoured shape aligns with your face and keeps the gap minimized between your mouth and the microphone to boost the voice quality. And, people love its long battery life.

Although the reception has been mostly favorable, the one complaint is that the 13-megapixel camera does not live up to expectations. Like many camera phones, it does not do well in low-light situations, and it is difficult to change the brightness.

Other Self-Healing Products

Are you wondering if self-healing polymers and new innovations in self-healing materials are wasted on clumsy cell phone users? Well, self-healing products are already in the public and private marketplace. An article in Forbes explains that now, tanks have the ability to let a bullet through its exterior and snap its damaged frame back into shape in less than a second. NASCAR also uses racetrack barriers that can withstand impact from a racing car, absorb it and return back to its original shape. And, cars are already employing self-healing paints and coats that enable healing in the sunlight. So, it's about time phones caught up with the future.

Chemistry World : 3D Printing of a Soft Network

Posted by Andreas Christodoulou

Description : 

3D Printing has the potential to revolutionize the way we make almost everything. Designers and engineers in the aerospace and automotive sectors have been using the process for decades to build prototypes. Many complex parts manufactured by 3D Printing are now present on aircraft, satellites, medical industry etc. etc.

3D Printing technology is advancing rapidly and its cost is falling dramatically. And this means something that was once restricted to a few elite industries is quickly becoming  more widely available and affordable. It's going to open up so many new possibilities for new businesses, new business models, start-up companies, new products and much more!

Now lets learn about a synthetic material capable of performing some of the functions of living cells : Oxford University scientists have used a specially modified 3D prototype printer to lay down a network of interconnected, electrically conductive droplets. 

This technology could find it's way into tissue engineering applications, helping to support cells that are being grown into healthy new organs - replace damaged human tissue or deliver drugs to specific locations.

"We aren't trying to make materials that faithfully resemble tissues, but rather structures that can carry out the functions of tissues," says Professor Hagan Bayley, who led the research reported in the journal Science.

3D Printing lets you build an object as complex as an organ, layer by layer or droplet by droplet, explains Cameron Ferris a research associate from the ARC Centre of Excellence for Electromaterials Science at the University of Wollongong.

The Newest Eco-Friendly Apartment Building Trends

Posted by Andreas Christodoulou

Description : 

The importance of conserving the Earth's limited resources finally seems like it's gotten through to mainstream culture in recent years. People are beginning to understand how crucial it is to find more efficient energy alternatives.

As of late, the use of environmentally friendly construction materials is on the rise. Many of these "green-living" ideas are implemented in today's modern apartments. When looking for a new apartment, here are some of the most popular ones to look for:

1. Strategic Orientation of a Home to Maximize Sunlight

Building an apartment in a location that receives a lot of sunlight is an ingenious way to save money on heating and lighting. Many engineers and architects are figuring out ways to design buildings that can take advantage of sunlight as much as possible. The orientation of the building makes a huge impact on how natural light is able to come through the windows, so strategic positioning is definitely an eco-friendly way to light up and heat up a place.

2. Exclusive Use of LED Lights

LED lights are a great choice for any apartment, house, business, or any situation where lighting is needed. Why? LED lights are not only brighter than the typical incandescent light bulbs, they are far more energy efficient too. Most LED lights give off a pleasant, white glow and only use about 20% of the energy that standard bulbs use. Renters can easily cut their electric bills in half after replacing all incandescent bulbs with LEDs.

3. Roofs Made from Copper

Metal roofs, especially copper roofs, are becoming a stylish choice in the world of apartments. First, they are quite inexpensive to purchase and install, and they also require very little maintenance. Secondly, they look great when paired with the right architecture. Copper roofs have a very long life span, with up to a century of use. Finally, they can be recycled with ease. What's not to like?

4. Rainwater Collection Units

If people have survived on rainwater for countless years, why can't we make use of it today? Rainwater collection units are set up in strategic locations around the apartment to collect the runoff. This water can then be used for watering the lawn and garden and general cleaning use.

5. Counter Tops Made from Easily Accessible Wood Sources

Granite counter tops have been popular for many years, but it seems that cheap, wood counters are spreading like wildfire through many apartment complexes. What's the appeal of wooden counter tops? Aesthetically, they obviously look good. More importantly, wooden counter tops that come from rapid growing trees like bamboo do much less harm to our forests and environment. When slow-growing trees are used for wood, the environment takes a much bigger hit because animal homes are lost and oxygen production is halted for a much longer amount of time.

6. Water-Saving Toilets

Using the restroom is something that all civilized people must do, flushing the toilet is an unavoidable consequence. Compared to standard toilets, those designed to conserve water can cut water consumption by 20%. These efficient systems can significantly decrease your water bill and put more money in your pocket.

7. Electric Stove Tops

Induction stovetops are much more eco-friendly than gas versions because far less energy is lost when turned on. Heat transfer through physical contact is a better alternative to turning on a flame that burns your money away with every use.

Tips On Making Your Office Greener

Posted by Andreas Christodoulou

Description : 

As we are all members of this planet, it is our duty to do our part to keep it looking beautiful. In an office setting, it could be difficult to keep this in mind while completing your daily tasks.

But being a little bit greener is not difficult and should not have to inconvenience you or your workers at all. Simple changes, like conserving electricity, using recycled office supplies, and cutting waste, are just a few ways you can do your part in healing the Earth.

Conserve Energy When Possible

One way to make an office greener is to conserve the use of energy when possible. Obviously, with computers as part of our every day lives, electricity is vital, but it can be minimized. Installing motion sensors on the lights in offices is a great way to cut electricity uses. This way, if someone forgets to turn off a light in their office, after a while, it will automatically shut off. Furthermore, urging everyone to turn off their computers at night could drastically reduce energy consumption. If possible, installing solar panels will substantially reduce energy use and also save money.

Use Recycled Office Supplies

As the world has yet to go completely paperless, it's impossible to stop your office from using natural resources, but things can be done to reduce the collective carbon footprint of the office. The easiest way is to use recycled office products, namely, recycled printer paper. But it does not have to stop there. There are other recyclable office materials that can not only save you money, but also, help save Mother Earth. For example, aftermarket toner is a recycled form of toner that is cheaper and greener, and it is an easy change to implement in your office.

Cut Waste

Cutting waste is an important part of going green, but sometimes waste can sneak up on you in aspects that you wouldn’t think about. Does your company have a water cooler? If it does, consider making the switch away from disposable cups. Instead, persuade your employees to switch to refillable plastic or metal bottles, maybe even hand them out as a gift. It would also be helpful to educate them on what can and cannot be recycled. Some times, the greatest ally you can have in trying to be conservative is knowledge, so a quick seminar about where to put certain materials could save time, money, and especially, the environment in the long run.

US Chemists Developed a Heat - Fire Resistant Camouflage Makeup that Protects Soldiers

Posted by Andreas Christodoulou

Description :

The heat of a bomb blast or IED explosion is so intense that it can fry the skin of any troop unlucky to be near. If service members are wearing camo paint, the consequences can be even worse: most makeup is oil or wax-based and can ignite instantly in a flash of heat and pressure. 

Camouflage makeup can do more than hide soldiers from their enemies though. Yeap, this camo paint brings a new era in shielding soldiers from heat threat.

This new form of a heat reflective camouflage paint shields soldiers faces in the field from the searing heat of those bomb blasts. This Next - Generation Makeup was developed by Robert Lochhead and a team from the University of Southern Mississippi, US, at the direction of the Department of Defense. 

The paint replaces its traditional carbon base with silicone that is non-flammable and can absorb heat - A chemical challenge to develop. The change means that just a thin layer of camouflage face paint could not only help soldiers escape detection, but prevent burn injuries and facial scarring from run-ins with explosives. 

The heat-resistant makeup not only provides protection from the searing temperatures of roadside bomb blasts and other explosions but it could also safeguard firefighters from more serious burns.

It keeps the left-hand strip at below 100°C after 10s under a blowtorch, whereas the unprotected strip reaches 400°C. Check out the video!
