Exploring the Power of 3D Printing Technology: Advantages, Applications, and Ethical Considerations

In this ppt slide we will discuss about 3D printing and below are the summaries point:- 3D printing technology enables the layer-by-layer joining of materials controlled by a computer, using liquid molecules or powder grains. It plays a significant role in mechanical engineering and aerospace engineering, providing prototype overviews, customization, and on-demand component production. Strengths include single-step manufacturing, speed, risk mitigation, and design freedom, while weaknesses involve high cost, energy consumption, material limitations, and emission of harmful particles. Ethical issues such as piracy and medical concerns are also present.  

3D PRINTING TECHNOLOGY

Introduction
3D printing is an emerging technology
through which materials can be joined
under the control of the computer. The
materials those can be used are liquid
molecules or powder grains in layer by
layer.

Working principal of 3D printing:
3D printing can be through using the
3D printer connected with the computer
and the system. At first, the 3D printer
turns the whole object into many little
parts. The process is done slice by slice
in bottom up approach.

Significance of 3D printing:
3D plays an important role in the field of
mechanical engineering and aerospace engineering. 3D
printing has made the processes included in these
industries easier through providing the overview of the
prototype before the development of the project (Lee,
An and Chua 2017). This printing technology has
helped in mass customization of the products along
with production of on demand components. Apart from
that 3D model developed through 3D printing provides
chances for verification and required correction in the
physical component.

Strength:
• Single step manufacturing.
• Speed
• Mitigation of risks
• Freedom of designing
Weakness:
• Expensive technology
• Consumption of high energy
• Emission of harmful particles.
• Limitation of the materials.

Ethical issues:
• Piracy
• Lack of rules and regulations
• Ethical issues in medical field.
