3. 3D Printing is an additive
manufacturing process that
creates a physical object from a
digital design. A digital model is
turned into a solid three-
dimensional physical object by
adding material layer by layer.

SCANNING

7. TYPES:
1.Photogrammetry: The method is based on taking 2D pictures around an object, from different angles, and stitching
them together into a single 3-Dimensional image. The last part being handled by software.
123D Catch, Trimensional, or Trio are all great apps for this. The software will match all overlapping points of the images and create
a 3D model.
2.Light-based scanning: Two common types :
*Structured light scanners send patterns of light onto the object to capture. Based on the deformations of the pattern it
determines the model form and creates a 3D mesh, or digital replica.
*Laser scanning measures the angle of the reflected lasers which it can translate into coordinates of an object and therefore
into a 3D mesh.

8. 3D Scanning Advantages:
1.Quickly capture all of the physical
measurements of any physical object.
2.Save time in design work.
3.Ensure parts will fit together on the first try.
4.Capture engineering optimizations inherent
in manufactured parts.
5.Utilize modern manufacturing on parts that
were originally manufactured before CAD.
6.Compare “as-designed” model to “as-built”
condition of manufactured parts.

20. DIFFERENCE BETWEEN 3D PRINTING & TRADITIONAL MANUFACTURING
TECHNOLOGIES:
3D printing has been around for a while, new advancements in the technology have started to lower the cost of
the process to levels that make it more feasible for general manufacturing use.
1.Prototype Production
2.Waste prevention
3.Large-Scale Production
4.Availability of Specific Materials
5.Scale of Produced Parts
6-3D can do complex shapes with less cost than the traditional machining.
7-Traditional machining needs skillful workers but the 3D printing need just the CAD design of the product.
8- No need of different tools for the production of different parts.
In addition of these points some important points are also as-
1- Using only one type of polymers usually (ABS polymer) in 3D but in other Processes you can use what you
want.
2-The 3D printed parts are not strong, they are just for sake of Prototyping.
However, the technology does have incredible utility for small, one-off production runs and the manufacture of
small custom work pieces that would normally need a lot of specialized tooling to make.
Overall, the use of 3D printing isn’t likely to completely replace traditional manufacturing any time soon.

21. 3D printing’s effects on our environment
3D printing is just one of the many advances in technology that will lead to a healthier environment around the world. Here are three major ways in which this
technology will usher in a cleaner, purer, safer world around us:
#1 Wide Spread Recycling at Our Fingertips
In the Late 80’s and early 90’s we saw a major shift towards recycling waste. Curbside bins were handed out to residents in most areas around the nation, and people
began to think twice before throwing out certain items. 1-plasticThis was due to advances in technology allowing for recycling plants to flourish. Fast forward 20-30
years and we are at the starting line of another major recycling revolution. Plastics, as well as eventually metals and other materials can be ground up and turned into
filament for 3D printers. Over the last year or so, there has been a movement underway to do this. Perpetual Plastic is one of these movements, as well as others like
the Filabot, which received over 300% of it’s goal in funding on Kickstarter back in 2012. Basically anyone with the proper tools can throw a used plastic bottle into a
machine, and after a few steps turn that into any of tens of millions of different items. If that’s not something to get excited about, nothing is. Scientists as well as do-
it-yourselfers are also working with metals, wood materials, and glass to push forward similar initiatives.
#2 Reduction in Fossil Fuel Use From Shipping
Every day millions of barrels of oils are used shipping items across the world. Whether it’s a UPS truck, Fedex 747, freight train, or cargo ship, global trade is a huge
business. Millions of people every day order off of 1-planeinterest sites like Amazon, and receive their products within 2 days time. That takes a lot of fuel. Where
there is fuel, there is pollution. 3D printing is already helping to cut back on shipments in many industries. Thus far, it’s barely made a dent in the amount of fuel
needed each day within the shipping industry, however, trends show it will make a significant dent within the coming decade. Today you can 3D print your child a toy,
yourself a smartphone case, or your loved ones jewellery, instead of having to order those items online and paying to have them shipped, or jumping into your vehicle
and running to the local Wal-Mart. In the future, almost everything will be able to be printed out, cutting costs, saving time, and most importantly preserving the
environment.
#3 Far Less Waste
Finally, 3D printers are cutting back on waste within the manufacturing industry. 3D printing is also known as “additive manufacturing.” That’s because it does just
that, slowly adds material to an item until it is complete. Most other manufacturing methods are subtractive. For instance, when you build a chair out of wood, you
don’t use ever single shred of lumber in that chair. You have scraps as well as saw dust left over. Same thing for
1-grassjust about anything that is manufactured these days. You almost always have waste material, which nine times out of ten, winds up in a landfill, or somewhere
even worse. 3D printers will save money for manufacturers, but most importantly cut back substantially on waste. Many companies include General Electric, Apple,
and Ford are already using, or have plans to use 3D printing within their manufacturing facilities.
IS 3D PRINTING ECO-FRIENDLY TECHNOLOGY ?
The reality today does not allow the 3D printing technology to be fully Eco-friendly. Different researchers reveal that this technology uses large amounts of energy,
larger than the amount used by milling and drilling machines. A research (Atkins Project) done at Loughborough University in the United Kingdom revealed that to
produce the same object of the same weight, some 3D printing processes require 50 to 100 times more electrical energy than injection molding machine.
Another setback is the heavy reliance on plastic materials for the printing process. Plastic as a whole is not considered an Eco-friendly material. Studies show that
industrial grade 3D printers have a substantial plastic by-product left behind that in most cases is not suitable for reuse.
Most people are afraid of technology, in that they feel it will lead to the worlds demise.
In my opinion technology will solve some of the most unsolvable problems we face today. Embrace it to the fullest!
