We built a prototype for a sheet casting tool to accommodate our needs and desires to produce large and evenly flat sheet materials made of bioplastics such as the gelatine and agar-based ones, and the alginate plastics we made last week. We tested the machine by casting a sheet with [...] and [...]. So far, the machine functions and we made a lovely 2mm sheet with it (which shrank a bit)l but could be improved by finding a better solution for keep the walls together – the silicon glue didn’t old. And also the wiper or squeegee could have a deeper wiping edge so the strips can act as walls. Excess liquid will creep up, and could be contained if the wiper sinks a little deeper by default.

And also the wiper or squeegee could have a deeper wiping edge so the strips can act as walls. Excess liquid will creep up, and could be contained if the wiper sinks a little deeper by default. Anyway, details details. Here's our working prototype!
