Literature Review: Additive problem for Manufacturing

This “Ten Problems for Manufacturing in the 2020s” booklet identifies ten relevant areas from very recent contributions put forward at academic level in the form journal articles, conference proceedings and students theses. Ten freely accessible internet references have been selected for each area and direct links are provided at the end of each chapter for own consultation. Our selected references do not intend to mirror ranking indexes nor establish novel classifications. On the contrary, they are meant to represent peer-reviewed, diverse and scientifically-sound case studies for vertical dissemination aimed at non-specialist readers. They will also be able to scoop even more references through the bibliography that is reported at the end of each selected reference.

Without further ado, these are the ten problems that we are going to introduce in this booklet:

  1. sustainability, 
  2. industry 4.0,
  3. smart,
  4. responsibility,
  5. additive,
  6. digitalization,
  7. supply chain,
  8. optimization,
  9. skills gap,
  10. distributed.

Each problem has its own dedicated chapter made of an introductory section, a short presentation of the ten selected references and a conclusions section.

The final chapter of this booklet will report the conclusions from each chapter again in order to provide a complete executive summary.

5 Additive

THE PROBLEM — Additive manufacturing or three-dimensional printing has introduced a novel production method in design, manufacturing, and distribution to end-users. As they open new doors to manufacture products that are costlier to manufacture by traditional methods, material selection for feedstock in additive manufacturing processes poses significant importance. Additive manufacturing adopters still face multiple barriers to the implementation, and the adoption rate is reduced.

CONCLUSIONS — Additive manufacturing allows structures fabrication in a layer-by-layer deposition process and is revolutionizing the manufacturing industry due to its ability to obtain near-net shape products, in a short time span, with almost no material waste. Polymers are the largest additive manufacturing materials market segment, with increasing focus on high performance polymers. Overall, 3D printing technology is still not mature and needs more development to reduce the material and machine costs, generate faster and more accurate printing methods, and work autonomously. In order to guarantee good properties of the boundary area between the base metal plate and composite direct metal deposition volume, the composite part should have similar compounds. Although there has been research advances in material usage in additive manufacturing technologies, optimal selection of additive manufacturing materials has not been thoroughly researched. As for design, consolidated parts would not be beneficial at end-of-life stage and lead to unnecessary waste of materials during maintenance. The knowledge regarding additive manufacturing consists of three main areas: materials and processes, design, and parts area. Design models integrated with decision tools can assist the design experts in developing new knowledge for Additive Manufacturing beyond certification. Regardless of the particular technology, at the present time, additive manufacturing still suffers from too long times for additive construction, especially for large components, which limits its application in practice to rapid prototyping. Evidence suggests that the value-adding capabilities of additive manufacturing are not yet understood and require further investigation.
