PLA is also used as a feedstock material in 3D printers such as Reprap and Makerbot.
More than 25 feedstock materials have been tested there.
Any conductive wire can be used as the feedstock material, including "cored" wire.
The level of contamination of the feedstock material is a key consideration.
The maceration of solids can be achieved by using a chopper pump to transfer the feedstock material into the airtight digester, where anaerobic treatment takes place.
The PTWA thermal spray process utilizes a single wire as the feedstock material.
All conductive wires up to and including 0.0625" (1.6mm) can be used as feedstock material, including "cored" wires.
To process the materials to be used as a feedstock to grow the structure, the feedstock material is cleaned, "cooked", cooled and pasteurized.
Traditionally used as fertilizer, it is now also used as a livestock feed as a cost-saving measure compared with other feedstock materials, particularly for beef animals.
These will depend on the feedstock material you want to recycle and the type of product you want to produce.
