Abstract EN
The polymer laser sintering (PLS) process is one of the most promising additive manufacturing (AM) technologies for polymeric materials.
However, the technique has challenges because the physical, mechanical, and chemical properties of the polymeric powder deteriorate due to the high temperatures prevailing in the build chamber during manufacture.
These high temperatures cause agglomeration of powder, which leads to a decrease in the flowability of powder.
There is also a related drop in the coalescence of the powder granules during PLS, which results in porosity that undermines the mechanical integrity of printed parts.
Moreover, the viscosity of the melt increases due to cross-linking of molecular chains.
This, in turn, increases the tensile strength of the printed components at the expense of the percentage elongation at break.
Thus, high prolonged processing temperatures decrease the reusability of polymeric materials used in PLS.
In this paper, a review of the studies conducted to investigate ways of reducing the effects of high temperature on polymeric powders is presented.
