What is 3D Printing?

What is 3D printing?

3D printing is a procedure of making three dimensional strong objects from a digital file. The creation of a 3D printed item is accomplished utilizing added substance forms. In an added substance prepare an article is made by setting down progressive layers of material until the whole question is made. Each of these layers can be seen as a daintily cut flat cross-segment of the possible item.

How does 3D printing work?

Everything begins with making a virtual design of the article you need to make. This virtual design is made in a CAD (Computer Aided Design) file utilizing a 3D displaying program (for the creation of an absolutely new question) or with the utilization of a 3D scanner (to duplicate a current item). A 3D scanner makes a 3D digital duplicate of an item.

3d scanners use distinctive innovations to produce a 3d model, for example, time-of-flight, organized/adjusted light, volumetric filtering and some more.

As of late, numerous IT organizations like Microsoft and Google empowered their equipment to perform 3d examining, an incredible illustration is Microsoft’s Kinect. This is a reasonable sign that future hand-held gadgets like cell phones will have coordinated 3d scanners. Digitizing genuine items into 3d models will get to be as simple as taking a photo. Costs of 3d scanners range from extremely costly expert industrial gadgets to 30 USD DIY gadgets anybody can make at home.

Not each of the 3D printers utilize the same technology. There are a few approaches to print and each one of those have various methods of how printing works. Few of them require layer printing whereas few may have normal printing.

A few methods use melting or softening material to produce the layers. Particular laser sintering (SLS) and fused deposition modeling (FDM) are the most common advancements using this method for printing. Another method of printing is the point at which we discuss curing a photo-responsive gum with an UV laser or another comparative force source one layer at once. The most common technology using this method is called stereolithography (SLA).

Application and utilizations of 3D printing

Applications incorporate quick prototyping, compositional scale models and maquettes, social insurance (3d printed prosthetics and printing with human tissue) and diversion (e.g. film props).

Other cases of 3D printing would incorporate reproducing fossils in paleontology, recreating antiquated ancient rarities in paleohistory, remaking bones and body parts in forensic pathology and remaking intensely harmed proof obtained from wrongdoing scene examinations.

3D printing industry

The worldwide 3D printing industry is relied upon to develop from $3.07B in income in 2013 to $12.8B by 2018, and surpass $21B in worldwide income by 2020. As it develops, 3D printing technology is bound to transform practically in every major industry and change the way we live, work, and play later on.

Medicinal industry

The standpoint for restorative utilization of 3D printing is developing at a greatly quick pace as specialists are using 3D printing in more propelled ways. Patients around the globe are encountering treatments through 3D printed inserts and prosthetics.

Bio-printingAs of the mid century, 3D printing technology has been considered by biotech firms and the scholarly world for conceivable use in tissue building applications where organs and body parts are fabricated using inkjet methods. Layers of living cells are stored onto a gel medium and gradually developed to form three dimensional structures. We refer to this field of examination with the term: bio-printing.

Aviation and aviation industries

The development in use of 3D printing in the aviation and aviation industries can, for a substantial part, be gotten from the improvements in the industrial and aviation sector. NASA for example prints ignition chamber liners using particular laser melting.

Therefore, in today’s time, where technology has expanded to a great extent, the use of 3d printers in nearly every industry is making a boom!

Print anything you want with a 3D printer

It may be the most eye-catching development and printing since Gutenberg invented the printing press 600 years ago a machine that can make copies of almost anything but this time in 3-D.It seems like science fiction but 3-D printing is already in use, building, hearing aids, jewelry even parts for NASA, now the technology is becoming available to anyone meaning you can turn your garage into a small factory.So what you build, if you could create anything, have a look.

And what you are watching is an ear being printed layer upon layer.Tiny droplets are deposited, building up the . So this is someone’s ear.This would be printed to be someone’s ear.Oh my goodness.The project is a type of 3-D printing called bio printing led by Dr. Anthony Attala at the Wake Forest Institute for regenerative medicine in North Carolina. The same technology you have at your very own home instead of printing sheets of paper with ink you’re actually printing tissues with cells.

The premise is simple, send a scanned image of a body part to the printer and the machine starts building, ears, noses, fingers.Dr. Attala’s goal is to transplant the parts directly into patients. So we’re actually testing a lot of these structures right now experimentally.

The way it works is the cells are able to anchor to the scaffold, they start making new tissue, and as that starts to happen, this scaffold goes away.

An ear takes between 4 to 6 hours to make printed with what’s called bio link, a mixture of biodegradable gel and actual human cells.One of the biggest advantages of these technologies is you are using the patient’s own cells and by doing so really you avoid the major problem of rejection.

Dr. Attala has specialized in regenerative medicine since 1990, but it wasn’t until this TED talk two years ago that the promise of building body parts caught fire.

90% of the patients in the transplant list are actually waiting for a kidney, you can actually see the printer back here has been printing this the kidney structure you see here.Here it is you can actually see the kidney as it was printed earlier today.

While implanting kidneys like this is still at least a decade away, it holds the potential to revolutionize organ transplants.

Until just recently the way that we made these tissues was to actually create them by hand one by one. When you start thinking about getting these technologies to many patients and creating thousands of these organs at the same time, you need to automate the process and that’s where bio printing comes in.

Meaning you can make thousands of kidneys. You could make thousands of organs you could pick the organ you want to make then you allow the printer to do them over and over again. Is this a finger? This is actually a finger. Right now after Attala’s bio printing is in the preclinical phase, simpler organs will be the 1st to reach patients starting with skin.

If this were in fact a wound it would be dropping real skin cells over the wounded area. The skin printing project is being funded by the US military with the hope of treating injured soldiers in as little as 5 years. But while Dr. Attala’s work is cutting-edge, 3-D printing isn’t a new.

The technology has been around since the mid-80s mainly used for prototyping in industrial settings. Prof. Hart Lipson from Cornell University says that’s changing. It’s has reached a level of technological maturity that is used beyond prototyping to actually make functional parts to be using the reality in the aerospace industry is a good example. Some commercial planes are not your fitted with air ducts that are 3-D printed, made smoother lighter and cheaper than the traditional method.

Hollywood is using 3-D printing to make costumes like parts of a suit in Iron Man 2. And a professor in California plans to 3-D print a house.

In every case a digital blueprint is either sketched or scanned, and then sent to a 3-D printer. The printing itself can be done by extruding a liquid usually plastic drop by drop, or by using a laser to fuse resins and metals.

What you have here is a sample of a titanium nose implant. Hart who calls himself I 3-D printing addict has just co-authored a book on the subject that will be released next week. The one thing he’s betting will spur demand for technology may surprise you.

I think food printing is to 3-D printing what gaming was for computers. Already students at his lab have printed chocolate, peanut butter even cakes. Beyond food there are few disciplines 3-D printing won’t touch, printing an iPod he says isn’t that far off.

If you think about the evolution of humans would like to distinguish ourselves from other animals by the ability to make tools, and 3-D printers are perhaps the ultimate tool.

But what happens to laws and regulations when you have a tool to print anything?

From guitars to race cars even a model of your unborn child, people who embrace 3-D printing are finding new uses for the emerging technology. Once used at the industrial level only 3-D printing has gone mainstream. Today in Manhattan you can wander into 3-D printing Stover the only of its kind and take home your own printer for $2200.

***Is the cofounder of Maker Bot. One of the reasons we opened a retail store is because 3-D printing is still science-fiction to a lot of people, the idea that you can have a machine and send it a digital design3-D model that’s a virtual, and it will turn into something real a physical model it just blows people’s minds.

From tools and toys to models and jewelry, maker bot’s printer allows anyone to design and create. We put the design in here with an SD card be press the big red M to get it to jump to life heat it up and now it is drawing in plaster.

To some the printing is still rudimentary and nothing more than a novelty item,***sees it as a natural evolution.

Back in 2008 you could download movies, you could download books, you could download music but you couldn’t download things. Maker bots printer only works with plastic and can print item smaller than a shoebox, still more than 15,000 have been sold.

Our biggest customers are NASA GE 7 out of the top architecture firms in the US.

The digital blueprints for items are found on a website created by***and his team called thingIverse. We’ve got a kitchen cabinet door handle, this is a fan duct for an air conditioner. Over 30,000 items that can be downloaded for free. IPhone case, and this is a fun one somebody needed carpet pin locks for their Toyota Rav4. It’s been dubbed Walmart in your home.

So we’re all used to shopping and when we want something we think okay were a my going to go buy it, instead of thinking can I make that instead? But when you can make anything there are seemingly no boundaries. Which is exactly the point for Cody Wilson.

We want to build the printable gun. The 1st in the world? Yeah but the important part isn’t to be the 1st, but to actually do it just to have one. Cody a law student in Austin Texas is spearheading a group that’s trying to create the wiki weapon, a digital design for a gun that anyone can download and build using a 3-D printer.

You’ve said that what you’re setting out here to do will create a weapon at every computer. Yeah in a way of thinking a computer that can be a weapon or literally a 3-D printer right. I don’t think most people want a weapon in their home. I think that’s fine I don’t think you should be armed right but I think you should have the choice to be.

While making your own gun in the US isn’t illegal, distributing the blueprints to others falls into a very gray territory, and that’s where Cody is running into a number of roadblocks so in the meantime is printing gun parts to avoid breaking any laws.

What’s coming out is the lower receiver of on AR 15. The lower receiver is the only regulated part of an AR 15 semiautomatic rifle crucial to making the weapon work. At the shooting range the plastic part fires 11 rounds.

It’s good considering we couldn’t even get the pin in so 11 is 11. Back to the drawing board. People will know the name air 15 today because it was infamously used in the Newtown Connecticut mass shootings, and your providing people digital blueprint to replicate the regulated part of that gun. That’s right, that’s right. That will upset a whole lot of people. Sure but many people are already aware of what’s going is, this gun has a proud strong reputation coming out of Vietnam, the civilian version. Used for military purposes. That’s right. It’s a people killer. That’s right that’s what a gun is, let’s not talk about Turkey shooting and hog hunting and stuff, what is a gun and is a combat weapon. And you want to give people a file to build one. It’s right yeah.

Though Cody says is not willing to go to jail over this if American laws prevent them from moving forward email look for another country whose laws allow it. We people people who use this technology to print heart valves, ears, nose, skin I’m sure there are people out there who could say what you have to print this gun wonder so many positive use of this technology? For us we are not makers thinking what’s the best thing we can make, it’s a political project, how do you achieve universal access to the firearm.

So while 3-D printing rose in a no man’s land, a few rules or regulations professor Hart Lipson is weighing the implications. It’s also important to anticipate the consequences of this technology for better and for worse.

My goal in many ways is to say there isn’t anything you’re going to be able to do about this, welcome to your printable future.

And that is our broadcast for tonight, and Caroline Jarvis. From all of us here at 16:9 thanks for watching and have a great weekend.

What is Polystyrene?

There is very little more annoying than those tiny packing peanuts that come in boxes with fragile items.They cling to everything, and no matter how hard you clean, you always end up finding them years down the line.As annoying as they are though, have you ever wondered what they are made of?Very few of us know.These peanuts join a larger group of plastics known as polystyrene, or more commonly referred to as “Styrofoam.”

The most common ways we tend to see polystyrene is in the form of Styrofoam cups, plates, or classic to-go containers.They also make up a lot of packing supplies, like the peanuts.Though many companies and many businesses use these products often, there are a lot of reasons to avoid these plastics that many consumers are not aware of.For example:

  • These plastics have been proven countless times to give off harmful chemicals when used.They especially are harmful when near food and drinks.Keeping food in to-go-containers, or drinking a hot beverage such as coffee or tea out of a container made of polystyrene can negatively affect your health.No one knows for sure exactly how long it takes for the plastic to contaminate food, or what kind of damage it causes, but most studies point to it not being good.When food is concerned, stay far away from these.
  • Most recycling plants do not accept this plastic and cannot recycle them.This means they end up in landfills and pollute the earth.Beyond causing garbage to pile up everywhere and harm the ecosystems, these plastics can sometimes find their way into the mouths of animals, especially birds.The plastic not only cannot be digested, but it poisons the animals that don’t choke on it first.Using these plastics can do a great deal of harm to the nature around you, even if you don’t intend for that to happen.
  • Small plastics can be harmful and dangerous to small children and pets.The plastic peanuts used to protect fragile items in boxes can be a choking hazard to anything that may accidentally try to ingest it.The best thing to do is to switch to a healthier and safer plastic to protest your important shipments, such as air-filled plastic pouches.These are easier to use, easier to ship, and much safer to dispose of.

Though many of us are used to having this plastic in our lives, studies have shown that using it may not be the best course of action.Whenever possible, find an alternative, especially one that you know will be recycled.You’ll be doing yourself a favor, helping out Mother Nature, and ensuring that both you and the ones you love will be kept away from potential dangers lurking in the shadows of a to-go container or a package protected by hundreds of peanuts.

What is plastic?

Many of us use plastic products without really knowing what it is, or how it’s made.In fact, even though the majority of people recycle, few know that there are different kinds of plastics and how to tell them apart.Not only do plastics come in different shapes and sizes, but they come in different compositions.

Before getting into the differences between plastics, we first have to look at the basics of plastic.The word plastic comes from the term used to describe anything that can easily be molded into different shapes, but once cooled, will keep the shape it has.Most plastic is synthetic, though contains some organic material.Because it’s not completely from nature, it has a very hard time decomposing, which is the reason many places in the world encourage people to recycle their plastics.Because of its durability, plastic has replaced a lot of other material, such as wood, which rots and breaks down easily.Sometimes even though these items are replacing other materials, they are designed so they still look like the traditional leather, wood, or ceramic.

There are seven common kinds of plastic that we encounter during our day.They are:

  1. Polyethylene Terephthalate (PET) – These are the plastics that make up soda bottles and disposable water bottles.They’re semi-rigid, and are usually very light-weight.These can be recycled and when they are, usually turn into clothing of some sort.
  2. High Density Polyethylene (HDPE) – This is a heavy duty plastic that is dishwasher and microwave safe.It’s mostly used for beverage containers and food storage.
  3. Polyvinyl Chloride (PVC) – This is the kind of plastic used for pipes, and also outdoor furniture.Studies have shown that using this plastic for food storage is harmful to people’s health, so most companies have stopped using it.
  4. Low Density Polyethylene (LDPE) – These are plastics that are often very light, like garbage bags, dry cleaning covers and grocery bags.
  5. Polypropylene (PP) – These plastics make up things such as bottle caps and straws.For a long time, most places could not recycle these and they often contaminated recycling collections.This has changed, and they now join the list of recyclable plastics.
  6. Polystyrene (PS) – Most recognized as styrofoam, they make up things such as packing peanuts and to-go containers.They’re extremely toxic, especially to wildlife that may consume it.It’s best if these products are avoided at all costs.
  7. Other – This group is mostly made up of plastics that are used to make common forms of Tupperware containers.The major problem is that even though they are marketed as food containers, they often leach BPA, which is harmful for humans to consume.If you’re going to use a container to store food or drinks, aim to find another, safer plastic.

Though some plastics are easy to distinguish, such as #4, which makes up many of the bags we get from stores, others may be harder to figure out.Luckily, many products put the number of the plastic either on the side or on the bottom of the item.Make sure to check it out both for your own safety, but also to match the recycling rules of your area.

What is PVC?

We’ve all heard the name, but not many of us know exactly what PVC is or what it’s used for.The most common use for PVC is what we’re all used hearing follow the acronym, and that is pipes.However, because of the nature of PVC, it is used for so much more than just transporting water.Before we go there though, we first have to look at what PVC actually is.

PVC is one of the seven kinds of plastic, and stands for polyvinyl chloride.Sometimes it’s just referred to as “vinyl,” which is the common term for it in the United States. We’re most used to seeing it being used for pipes, though it can be used for a wide variety of other products, such as outdoor furniture and toys.Some important things to remember about PVS plastics are:

  • When heated, these plastics give off chemicals that are extremely harmful for humans to consume.Because of this, they should not be used to store food or to heat food in.Many companies used to use PVC as part of their food containers, but since this discovery, they’ve stopped making containers with PVC.If you own any older food storage containers, it’s important to check which number plastic they are, and to make sure that they’re not using any harmful substances.
  • PVC has been around for a while, and has been used for a variety of things.One of the uses of PVC includes waterproofing clothing during the 20’s and from there have expanded into an even bigger market.It’s been used in the latex of inflatable structures, and to replace a great deal of construction supplies.
  • Because PVC is so durable and doesn’t rust or react to UV light, it has replaced a lot of structures such as pipes.It’s also extremely cheap to produce, so many companies use it as an alternative to other, more costly materials.As of today, thousands upon thousands of homes are supplied water through PVC pipes.
  • PVC is extremely flexible and can be made transparent.In many countries in Europe, PVC is still used widely as a means to keep food fresh.It’s a company favorite because of its low cost and its ability to protect food without affecting its taste.It can also be found in as a huge part of toy packaging.It’s flexible and durable without driving up products costs.

PVC can be found in most areas of our lives, even though we don’t notice most of these times.The next time you rip open a new package, step into a hospital, uncover a piece of meat from the grocery store, or even pour yourself a glass of water, take a moment to think about how much plastic we use and consume on a daily basis, and how PVC has revolutionized the world.The magnitude of its impact is mind blowing.

What is Polythene?

Though we come in contact with polythene every day, very few people know much about it. In fact, if someone were to say the word, most wouldn’t even know what it is. Polythene is the name for two different kinds of plastics. One comes in the form of garbage bags and shopping bags, while the other is found in more rigid forms, such as lawn chairs and plastic boxes. With a wide range of products, there’s very little that we use that isn’t made from one of these forms of the plastic. If you’re wondering about the differences between the two, wonder no longer. Below is a glance at the two kinds of polythene and what sets them apart.

  • High Density Polyethylene (HDPE) – These plastics tend to be a little thicker than its counterpart, and make up items like folding chairs and tables. One interesting thing is that one of the first things this plastic was used to make was the hula hoop. Durable and reliable, this plastic was discovered recently and we’ve been in love with it since its discovery. It can be recycled, but unfortunately loses a bit of itself during the recycling process. Make sure to check with your local recycling plant before throwing these items into the pinwheel these plastics are becoming more widely accepted as something that can be recycled, some plants still do not accept it.
  • Low Density Polyethylene (LDPE) – This is an easy to spot plastic. It makes up most of our shopping and grocery bags, as well as our garbage bags and sandwich bags. It’s also used to make some bottles and a few pieces of common lab equipment. This plastic tends to be a bit more flimsy and not as rigid as the high density variant. Its main purpose is to keep things sealed and safe. Though in the past, many recycling centers did not accept bags and other forms of this plastic, in recent years it’s becoming more and more common for them to be accepted and recycled. It’s extremely important to double check the rules for recycling these bags, as sending them in to a place that doesn’t recycle them will contaminate the collection. Like the high density polyethylene, however, it loses a bit of its quality when it goes through the recycling process.

The good news about both of these plastics is that they have been proven safe to use around food and overall don’t expose us to harmful chemicals. While safety concerns regarding bags and children have always been circulated, there is little risk of getting sick from the bag itself. Because of this, feel free to continue using them to store your food and to keep your important, but sensitive items safe. Remember to save your bags, try to reuse them as often as possible, and when you can, recycle them. Because some programs still don’t accept them as something that can be recycled, try to avoid creating more waste by bringing a tote bag shopping rather than accepting a plastic bag.
