Is 3D Printing Environmentally Friendly?

is_3d_printing_environmentally_friendlyThe truth is that 3D Printing really isn’t much different than typical manufacturing in terms of its environmental impact. So, it’s not necessarily environmentally-friendly, at least at this point. While it may seem a lot cleaner, because it is electronic, it consumes more energy than typical production. In fact, it consumes a lot more energy.

When compared to assembly-line style manufacturing, 3D printing consumes a whopping one hundred times more energy. However, to balance this out, most 3D printing happens with plastic materials, which, while not the most eco-friendly materials around, do have the capacity to be melted down and reworked. So, this is one “greenish” element of 3D printing.

In the future, those who work on 3D printing technology may be able to reduce the amount of energy which is consumed in order to run 3D printing presses. At present, though, this energy expenditure is remarkable high. Nonetheless, 3D printing technology offers a host of benefits to society and these benefits are going to keep coming. So, there is more to consider than environmental impact.

3D printing is the future and, at some point, it may replace assembly lines completely. However, it will be a long time before this type of technology is everywhere. This may not be a bad thing, as assembly lines keep people employed and 3D printing presses may require less human supervision, as they are highly-computerised.

Some companies are attempting to reduce the environmental impact of 3D printing by re-using plastic materials which don’t turn out correctly. 3D printing isn’t a perfect process, so some items which are made via 3D printing don’t meet quality standards. In these cases, they may be melted down and made into other things. This eliminates wastage. This type of re-use isn’t possible with most assembly-line style manufacturing processes.

3D Printing Does Have Eco-friendly Benefits

Another environmental benefit is that less materials may need to be used during the 3D printing process. It’s possible to make items of lighter weight via 3D printing presses, versus products which are created with traditional manufacturing methods. Since less materials are utilised, more resources may be preserved. This speaks to sustainability. As well, since energy is expended making materials, needing to use less materials counterbalances the energy expenditures of 3D printing presses.

How to Stay in the Loop

If you’re interested in the power and potential of 3D printing, as well as its environmental impact, you’ll find that staying in the loop is pretty simple. Every day, new articles about this form of manufacturing technology become available online. Doing occasional Google searches for new information should keep you in the loop.

3D printing technology is trickling down to the common man and women. For example, it’s possible to buy 3D printing pens which make structures out of plastic threads. The plastic threads are heated and they are extruded. These fun toys are safe enough for older children to use and many adults enjoying trying them out, too. Also, 3D printers for home use are now available.

Is 3D Printing Food Safe?

Is 3D printing food safe

Is 3D printing food safeIs 3D printing food safe products possible?

3D printing technology has already changed the landscape of manufacturing completely, making a lot of modern miracles that seemed impossible before – like making critical organs (such as a heart, for example) on demand from biological material – a reality, but there are some that are concerned that 3D printing products that will come into contact with food aren’t safe.

On the other hand, there are a lot of folks in the 3D printing world that would argue the contrary.

These people say that the products they produce through the 3D printing process are just as safe to use around food as those made through more traditional approaches, if not more so.

Who’s telling the truth?

Is there such a thing as 3D printing food safe products?

Find out right now!

Is 3D printing food safe products possible?

You bet it is!

Sure, there are some hurdles that need to be cleared for these kinds of products to be completely safe when exposed to food stuffs for human consumption, but by and large there aren’t any real differences in these 3D printed products and those made through other means of manufacturing.

The number one risk that 3D printed products have to contend with as a bacteria buildup in the material used during the printing process, which happens a lot more often than most people would like to admit.

This is because the material used for 3D printing doesn’t have to be stored – or heated – to a specific temperature to be used. When you’re making plastic tupperware, for example, the plastic material itself has to be superheated until it’s a liquid and able to be cast into it’s final shape.

No bacteria could survive in temps like that.

The same is NOT true for 3D printing materials, which can be left alone at room temps (for the most part), giving bacteria plenty of time to come to life and inject themselves into the deeper layers of the product.

Secondly, 3D projects that are printed need to be sealed completely – not only to protect the finish (and the finished product) but also to make sure that the joints have all adhered properly to one another.

This is incredibly important, but you run the risk of using a sealant or an adhesive that may not be so good for the human body – even if it’s only consumed in small amounts passed along from contact with food.

Finally, you have to worry about the kind of filaments used in the production of these 3D printed food safe products.

A lot of the new filaments used in projects today are not only 100% food safe across the board, but also made from natural or recycled/reclaimed materials. These are good for the body as well as the environment – not to mention cheap and renewable – which is fantastic news for all involved.

But older filament materials aren’t quite as safe or as sophisticated. Those are the ones you need to look out for. Natural PLA, for example, is always going to be 100% safe (it’s made from corn starch), whereas ABS is a dangerous toxin you can’t have anywhere near your food – or your mouth!

At the end of the day though, is 3D printing food safe products possible?

You bet it is!

The Basic Things You Need to Know About CAD 3D Printing

The Basic Things You Need to Know About CAD 3D Printing

The Basic Things You Need to Know About CAD 3D PrintingIn recent years, computer aided design (CAD) 3D printing technology has become well-known and widespread. As 3D printers and scanners rapidly move away from being the subject of sci-fi fantasies and toward being attainable home technology, you might find yourself wondering, “What is CAD 3D printing?” Here are the basics you need to know about 3D printing and the way it is revolutionizing production.

WHAT IS CAD 3D PRINTING AND WHAT CAN IT DO?

In 3D printing, also known as additive manufacturing, a digital blueprint for a three dimensional object is sent to a printer, which “prints” the object by layering materials. 3D printing allows for many of the products we use every day to be manufactured more quickly and efficiently than traditional manufacturing techniques.

Polymer is the most common material 3D printers use to create an object, but most other materials can also be used. Simple trinkets and toys are no longer the only thing 3D printers can create. Additive manufacturing is becoming increasingly popular in the production of food, and the medical field has been utilizing 3D printing for years. Medical scientists are even experimenting with the possibility of printing transplantable organs made from layering live human cells. In China, massive CAD 3D printers printed five houses in one day, at a cost of around $5000 apiece.

Virtually any object that can be replicated and created by the layering of materials could eventually be printed by 3D printers.

HOW DOES ARE THE BLUEPRINTS FOR A 3D PRINTER CREATED?

Blueprints for 3D printers are stored as digital files that can be read by the printer.

Sometimes, an existing object is replicated using a 3D scanner. The scanner creates an accurate blueprint by using one of several techniques to scan an existing object with light or lasers and create an accurate blueprint. 3D scanners can be small enough to fit on your computer desk or big enough to replicate a house.

Other blueprints are created with 3D modeling software. Like 3D scanners, modeling software can be very simple or very complex. Programs available on the market right now range from free open-source programs that can be used by anyone at home, to complicated industrial-grade software used by serious manufacturers and engineers.

WHAT IS CAD 3D PRINTING AS FAR AS AVERAGE TECHNOLOGY CONSUMERS ARE CONCERNED?

3D printing has been available to hobbyists at home since 2011. Use among average consumers is on the rise as affordable home 3D printers can now be bought for less than $500. With free modeling software and simple, inexpensive scanners also readily available, 3D printing technology is rapidly becoming common home technology.

Consumers are able to purchase CAD files of blueprints to use with their home 3D printers if they are not capable of designing their own. Similarly, CAD enthusiasts who do not own 3D printers can inexpensively hire services to print the CAD files they create. Websites for home enthusiasts to sell the objects or files they print are also becoming more popular.

Some advocates for CAD 3D printing predict that commerce will be revolutionized as consumers will eventually be able to print many of the products they buy in their own homes.
