Скачать или смотреть Laser sintering of polymer particle pairs: Experimental setup

Selective laser sintering (SLS) is a 3D printing technology with the potential to fabricate lightweight products with complex design. During the manufacturing process polymers undergo a varying temperature profile during which the particles partially melt and thereby sinter together producing a complex microstructure. Incomplete sintering of the polymer particles, results in significant remaining porosity as well as limited interlayer adhesion causing poor mechanical properties of products. Therefore a dedicated experimental setup is developed, which incorporates the main features of an SLS printing device and at the same time allows in-situ visualization of the sintering dynamics by means of optical microscopy and X-rays. The combination of a full material characterization with sintering experiments under well-defined conditions will pave the way for rational material design in SLS.
