To test and demonstrate the dispensomixer at work, we choose pellets with PLA as the matrix polymer and two 2D clays as additives: Montmorillonite (MMT) and Cloisite (CLO). For both additives we have masterbatches composed of 10% additive and 90% PLA. We set as our objective to fill a 150 g plastic cup with a mixture composed of PLA with 2% MMT and 3% CLO. Thus, we should dispense 30 g of MMT masterbatch, 45 g of CLO masterbatch and the remaining 75 g from pure PLA polymer. The test is summarized in the example notebook described in Supplementary Information † and available in the repository .
