Transcript of 3D PRINTING


3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
Can change everything with 3D printing?
Real experiences
Imaginarium, a toy shop, has a new project related to 3D printers. They offer an online tool which gives you the option to design your own game. Then, you send it to the shop and there they print your design
Types of 3D printers and Materials
Creating 3D pieces

Let's explain what a 3D printing is, how it works and what kind of awesome things you can do with it, like printing organs or even a Moon Base. But, that is not all, you also can print another 3D printer!!
What a 3D printing is and how does it work
History of 3D Printing
3D printing was developed by Charles Hull, the founder of 3D Systems in 1984. Mr. Hull, born May 12, 1939, was an inventor of over 60 U.S. patents in the fields of ion optics and rapid prototyping. In his patent for the “Apparatus for Production of Three-Dimensional Objects by stereo lithography”, issued on March 11, 1986, he defined stereo lithography as a method and apparatus for making solid objects by successively “printing” thin layers of the ultraviolet curable material one on top of the other.
Printeer - a 3D printer
for kids & schools
There are many programs to use in 3D printing, but as I am novice in this topic I think the programs that are explained in this video are the best for me, because they are the most common and easiest ones.
3D Printing can be very beneficial for us, because it gives you the option to create many things that can make our life better an easier. In the following videos you can watch many of these benefits.
In a digital age, technology skills are some of the most important a child can learn. We also know that kids learn best when they are empowered and engaged. With Printeer, we have made 3D printing, one of the world’s most exciting new technologies, accessible and fun for kids of all ages. Now playtime and learning time can be one and the same, and 3D printing can finally be in the hands of the world’s most creative people.
Houses created by 3D printers
The most common materials used in 3D Printing are plastics, but in specific printers you can use other materials such as chocolate, bio ink, metal, rubber...
In this video you can see how a very big 3D Printer can make real houses where people can live.
False teeth, hip joints and replacement knees – and potentially printable skin and organs – will drive growth in the burgeoning market for 3D printers over the next decade, according to new research.
3D printing gives you the option to create objects very different between them. In the following video you can see some of these objects you can create with 3D Printing.
Objects made by 3D Printing
Advantages and disadvantages
- Accessibility
- Affordable pricing
- Huge Variety/Customization
- Constant improving prototyping/ increasing productivity
- Improved Life Quality & Welfare
- Violation of copyrights
- Harm authenticity
- Printing Weapons
- Scan & Fraud
As you can create whatever you want, 3D Printing can be used for very positive things, but at the same time you can use it for negative issues.

The following video is not a good example of a right use of 3D Printing. This videos shows you how easy it is to create your own gun.
A three-dimensional printing process that makes a solid object from a computer image by using a computer-controlled laser to draw the shape of the object onto the surface of liquid plastic.
Binder Jetting:
It is an Additive Manufacturing (AM) technology that creates artifacts through the deposition of binder into a powder bed of raw material. Once a layer has been printed, the powder feed piston raises, the build piston lowers, and a counter-rotating roller spreads a new layer of powder on top of the previous layer. The subsequent layer is then printed and is stitched to the previous layer by the jetted binder.
It is the process of forming a solid mass of material by heat and/or pressure without melting it to the point of liquefaction.
Rapid prototyping:
It is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data.Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology.
Reverse Engineering:
The process of recreating a design by analyzing a final product. Reverse engineering is common in both hardware and software. Several companies have succeeded in producing Intel-compatible microprocessors through reverse engineering. Whether reverse engineering is legal or not depends on who you ask. The courts have not yet made a definitive ruling.
Fused Deposition Modeling (FDM):
It is a type of additive manufacturing technology that enables the construction of three-dimensional objects, prototypes and products through a computer-aided or driven manufacturing process. It is used in 3-D printing or the design of solid models and prototypes in a layered or additive approach. FDM is also known as fused filament fabrication or fused deposition method. Fused Deposition Modeling (FDM) is trademarked by Stratasys Inc., a leader in building FMD-based 3-D printers.
In this glossary I will write some important words in 3D Printing, which before I started with this project I didn't know.

The questions of the interview

1. What is 3D printing for you?

2. What were the main reasons so you start in the world of 3D printing?

3. How did you learn to create 3D pieces?

4. How did you get your own 3D printer?

5. What kind of pieces do you create?

6. What was the first piece you printed?

7. Between the pieces you have created, what is the most important one to you?

8. What kind of materials do you use for your impressions?

9. What benefits can offer 3D printing to our society?

10. What should improve 3D printing to achieve better results and effects?

11. In the future, how important can be 3D printing?

I have interviewed Gorka Urarte (expert in 3D Printing) to know more about this world.
My reflection
Before I started researching about 3D Printing, I didn't know the possibilities that it gives in many ambits of our society.

3D Printing can improve some aspects of our diary life and do it better and easier.

Final result
Final result
The research I have done about 3D Printing has provided the option to start knowing more about the topic. At the beginning, I didn’t feel very motivated and confident, because I didn't know anything about the topic, but when I started researching I felt more confident about what I had to do and little by little I felt more engaged.

After analyzing the general information about the 3D Printing, I feel very motivated, because I have seen that this topic could be useful and important for everybody in the future, so if I become in an expert in this topic I will take advantage of this in the future.

According to the weak points, as I have commented before, I have had some problems with the language, because some technical words are new for me and at the beginning I don’t understand the information well, but investigating, now I am able to understand this information.

My reflection
My reflection
In this step, I learnt the characteristics that a good interview has to have and also I learnt how to prepare an interview.

Moreover, This interview provided me the option to know in a real way how people can use 3D Printing in the real life and what benefits can you obtain using this.

Apart from that, I saw how a person without knowledge but with a positive attitute can learn doing new things and activities. So, I learnt that anyone can learn anything with a positive behaviour.

My reflection
In this part of the project, I have felt more confident and motivated, because I have found the meaning to the project. I have completed some tasks as creating the pieces and interviewing an expert, that have been very useful and meaningful for me, because I could view in a visual way what I have learnt during the process.

My strongest and weakest points are linked, because to improve the negative aspect, I have used my most positive point. The positive one has been the positive attitude I have had during the process and the negative one the lack of knowledge and experience about 3D Printing I have demonstrated.

I have had a positive attitude when I have had problems while I was creating the pieces. At first, I couldn’t create the pieces because the programs I had to use were very complex, but with the help of my friend and my positive attitude I have achieved the objective I had.
