Jet set: Layer-by-layer alternate stepwise deposition of poly(L-lactide) (PLLA) and poly(D-lactide) (PDLA) is used to fabricate a polylactide (PLA) stereocomplex on a substrate (see picture). Multiple inkjet passes improve the crystal structure of the PLA composite without intermediate rinsing steps.
