Latest trends in Additive manufacturing

Abstract

Additive manufacturing is the most recent and the most revolutionary technology in the production industry. It is an unconventional method of manufacturing. In this manufacturing method, material is added one layer upon another layer to get the required shape and size of object. Most complex objects can be built very easily by this technology. Additive manufacturing has the capability to reduce the supply chain by reducing a number of processing stages of a product. Additive manufacturing technology developed a lot from the day 3D printing technique, introduced as Stereolithography in 1984 by Charles W. Hull. Today we have different types of 3D printing techniques such as polymer resin based printing, wire based printing(FDM) and powder based printing(SLS) and some hybrid Additive manufacturing like High speed sintering. Additive manufacturing has applications spread from Aerospace industry to Toy industry and from Biomedical industry to Construction field. Additive manufacturing leads to “Social manufacturing” which involves customers in all stages of product manufacturing. Most of the large scale industries are investing a large capital in R&D for this 3D printing. Many startups are entering into the market each day. Today bio-compatible kidneys, bones and even hearts are bio printed, multi-storey buildings have already been 3D printed and research works are in progress. Now researchers are stepping towards 4D printing which uses “Intelligent” materials which can be coded. Research work is being done on different Additive manufacturing techniques and different materials and process parameters. This paper is a review of Additive manufacturing and it’s latest trends. The Trends related to printing technique as well as materials.

Computational Methods for Biofabrication in Tissue Engineering and Regenerative Medicine - a literature review

“…4D printing produces dynamic structures whose functionality, shapes, and properties change based on the environmental inputs. Computational approaches can guide the deposition process not only for spatial features of the constructs but also to organize its potential functional responses to different stimuli [68]. In [58], leveraging biological data, a DT of the whole bioprinting process with the cellular resolution, is proposed as a strategy for a holistic and intelligent computational facilitation of biofabrication.…”

“…Thus, product design must consider the cellular component's role in the product's evolution to its final form, requiring consideration of the product's evolution after the initial construction and under different environments. Computational approaches support this by guiding product design considering potential functional responses to different stimuli [73], following the four-dimensional (4D) printing paradigm [74], producing dynamic structures whose functionality, shapes, and properties change based on the environmental inputs. Since cells are the main actors of transformation and response to the environment, product design must consider their behavior in predicting the final product form.…”

A Recent Trend on Additive Manufacturing Sustainability with Supply Chain Management Concept, Multicriteria Decision Making Techniques

“…e printing magnets are obtained with good thermal performance by using magnet filament from recycled material [76]. Kalyan et al [84] explored the AM vaccums in future applications such as in situ monitoring (online measurement), topology optimization, smart manufacturing, hybrid 3D printing, and standardization [84]. e growth of AM process increased gradually day to day.…”

Experimental Study on the Possibilities of FDM Direct Colour Printing and Its Implications on Mechanical Properties and Surface Quality of the Resulting Parts

“…With the intensive use of additive manufacturing in increasingly different fields [ 1 ], whatever its nature (MEX—material extrusion, VPP—vat photopolymerization [ 2 ], etc. ), the attention of researchers has been focused on improving the process through various methods, such as post-processing of the parts obtained to increase mechanical performance, improving surface quality, or offer new capabilities to the process, such as the possibility of true colour reproduction.…”

“…On the topic of part colour and its study, several studies have been conducted [ 1 , 3 , 4 , 5 , 6 , 7 ] where the main focus of the study was the possibility of colouring 3D-printed parts regardless of the type of additive manufacturing.…”
