· Another technology for printing whole buildings is artificial concrete, which was developed in Italy by Enrico Dini, founder of D-Shape. This machine was inspired by the technique of Stereolithography (SLA), but this time it uses sand. By replacing the UV with an inorganic binder, it gives the material the properties of marble.
Processing begins with separating foreign material (primarily soil, vines, stems, and leaves) from the peanut pods using a series of screens and blowers. The pods are then washed in wet, coarse sand that removes stains and discoloration. The sand is then screened from the peanuts for reuse. The nuts are then dried and powdered with talc or ...
