Journal Club Theme of April 2014: Challenges and Opportunities in 3D Printing: A Mini Introduction

3D printing, or Additive Manufacturing (AM), has drawn significant attention from both general public and research community in recent years.  Although the first prototype of 3D printing (called rapid prototyping) emerged about three decades ago and has gone through significant development, the recent explosion in its popularity appears to be mainly due to intensive media reports. However, I personally feel what is truly underneath this increasing popularity is the development of 3D printing has reached a critical point where the revolutionary transition of 3D printing from a prototyping tool (which is cool but few people take it seriously) to a high fidelity manufacturing powerhouse is occurring, which will dramatically change how materials, parts, or devices are made in the future. As will be outlined below, 3D printing is a very broad concept and there are many dramatically different 3D printing technologies. In addition, 3D printing research is part of the large manufacturing research community, which consists of many extremely innovative people. Therefore, I will briefly introduce the different 3D printing technologies then comment on the challenges and potential opportunities, which I am sure will be incomplete. I hope this can lead to more in-depth discussions.

New view of DNA

Recently, the classical view of DNA as an isotropic elastic rod has been questioned. Here we model DNA as an elastic rod inlaid with fibrils, based on which we have made prediction that is in consistency with experiments. Our analysis suggests that the bending of short DNAs can be facilitated if there exists a specific structural heterogeneity.

Viscoelastic & Viscoplastic Behaviour of flex printed circuit boards under bending loads

Hello,

I am currently working on my M.Sc Thesis project of fatigue lifcycle of Flex printed circuit boards which is composite material of Polymer & Metal.Want some help who has worked on this topic which deals with Viscoelastic & Plastic behaviour of materials under action of pure bending loads.Help & Guidance would be appreciated.Need to come up with an equation which has stress & strain relating to lifecycle of Flex printed circuit boards.

Awaiting your reply,

 

Regards,

Nishant

Ping!

I heard a sound in my email Inbox. It was from the editor-in-chief of Elsevier's Engineering Failure Analysis journal. I opened the email and read that my paper was accepted to be published under some conditions for revisions per peer reviewer's comments.


Mesh free coupled with FEM

Hi All

 

I would like to know , If part of our model has geometrical complexity , is it reasonable to use meshfree method for that area ? does it fasten or ease the analysis ? how to couple it with FEM ?

Simpleware Case Study: Pseudomorph Modelling

In this project, Simpleware's image processing and mesh generation software was used to complete an ancient geological process through new technology. The goal of the project was to create a pseudomorph, an object that maintains an original shape over time while changing its inner materiality.
 
The pseudomorph in this project represented a snail that had become fossilised as an air void within the Jurassic Coast’s rockbed over millions of years. High-powered CT technology and Simpleware software was used to visualise the microstructure of Portland roach stone and to extract a mesh of the air void suitable for 3D printing as a new object.
