Leaf Protein Concentrate (LPC) is a protein rich substance similar to a curd or cottage cheese. LPC can be made from many varieties of leafs and can feed lots of people for a very low cost. In order to make LPC, the juice must be extracted from the leafs using a press. For more information on how to make LPC read the Skills and Knowledge section below.

Bill of Materials[edit | edit source]

  1. PLA Filament
  2. Leaf Press Base
  3. Leaf Press Lid

Tools needed[edit | edit source]

  1. MOST Delta RepRap or similar RepRap 3-D printer
