Dear Aravind Tripathy , thanks for opening the current discussion,

* I think the 3D printing or Additive manufacturing would pave the way for the advanced manufacturing of specific or critical applications to improve their performance by satisfying the following:

- Design flexibility

- Weight reduction

- Offering conformal cooling if needed

- Other advantages might be offered according the function of the fabricated part * 3D printing will feed the other manufacturing technologies with advanced tools that would make a significant improvement in their production quality.

* For the social impact, I think the main point could be related to the customization of the products.

As an example, you can check my current project updates and publications through the following links:

Hello Mr. Aravind Tripathy I think 3D printers are currently being used more to make custom equipment and have not yet found their place in the construction and wholesale industry, however, this technology is advancing and in the near future, two approaches can be taken from it. First, with weight loss tricks, flexibility, multiple uses of a single piece, making products easier to assemble, and reducing parts, it can make the technology economical enough to be cost-effective compared to other methods.

And secondly: This technology should be modeled on mass production by increasing the speed of part production, reducing the cost of materials, and optimizing for production. Also, due to the automation and robotization of production lines, there is more hope in using this technology in production lines.

Dear Aravind Tripathy ,

Since the 1980s when Chuck Hull proposed 3D printing, there has been a change in way of building.

Additive manufacturing, so well known to mankind, has earned ally of 3D printing (3D printing is additive manufacturing, but additive manufacturing is not just 3D printing).

The advances come from possibility of building parts, and items that Subtractive and Formative Manufacturing are unable to meet.

The manufactures complement each other and one manages to do what the other does not.

The paradigm shift has been taking place in last 40 years, with more force from 2010 to the present day. See new machines, new materials, new ideas!

The impact on society starts in manufacturing process in Additive Manufacturing, which is insertion of material (raw material) to make the object, without wasting material. This is significant for product cost, environment and nature.

Additive Manufacturing contributes to more agile solutions and prototyping with reduced cost. This directly impacts the cost of developing a product and thus its final cost.

I hope I contributed to your discussion.

Regards,

Wiltgen
