In this work, machine learning has been applied to predict the tensile strength of the 4D printed materials.
The morphology of the 4D printed materials was determined by scanning electron microscope (SEM).
The stimuli that can be applied to the 4D printed parts can be in form of physical and chemical interactions, in which the material has to be stimulus-responsive active materials [4].

Recent days, nano ZnS samples which have different morphologies used in biomarkers materials has aroused great interests.
Combining water soluble ZnS and preparation water soluble quantum dots to biological detection that have became an important problem of biomarkers materials research[5] .
In 2005 JIANG et al.[9] presents the emulsion method with ZnCl2 and TAA as raw materials, and span-80, tween-80 as compound surface active agents and utilizes the a forementioned method to produce nanometer ZnS particles.
The starting materials were Zn(Ac)2 , TAA and ethyl alcohol,all the reagents used were analytical grade without further purification.
