Laws of 4D Printing Article

Farhang Momeni, Jun Ni

Engineering 2020, Volume 6, Issue 9, Pages 1035-1055 doi: 10.1016/j.eng.2020.01.015

Abstract: Accordingly, four-dimensional (4D) printing is a manufacturing process that involves multiple researchfields. 4D printing conserves the general attributes of 3D printing (such as material waste reductionshow that two types of time constants are needed to capture the correct time-dependent behavior of 4Dintroduce the concept of mismatch-driven stress at the interface of active and passive materials in 4Dwith governing equations can serve as general design principles for future research in the field of 4D

Engineering 2015, Volume 1, Issue 1, Pages 113-123 doi: 10.15302/J-ENG-2015014

Abstract:

In order to build a ceramic component by inkjet printing, the object must be fabricated through theWe can identify the processes by which these drops interact to form linear features during printing,but there is a poorer level of understanding as to how 2D and 3D structures form.The stability of 2D sheets of ink appears to be possible over a more limited range of process conditionsDespite these uncertainties, there have been a large number of reports on the successful use of inkjet printing
