1. A method comprising:
receiving pressure-point data of a foot using a pressure-analysis device; and
generating information for configuring a 3D printing device to print an orthotic or insole comprising a plurality of compression cells at particular locations of the orthotic or insole correlated to locations represented by the pressure-point data, each compression cell having a solid physical structure comprising a lattice structure having flexible connected elements formed therein with each compression cell being directly connected to and forming a continuous interdependent lattice network with its neighboring compression cell or cells such that pressure applied to one cell disperses weight to all cells in the network, wherein at least one compression cell comprises:
a circular top portion and an opposing circular bottom portion such that the circular top portion and the circular bottom portion connect the compression cell to its neighboring compression cell or cells, wherein the circular top portion and the circular bottom portion are connected to each other by a plurality of helical or spiral flex elements,
wherein generating the information comprises determining a pressure number for each location represented by the pressure-point data, and wherein each compression cell is selected to correspond to each pressure number such that the lattice structure varies depending on the pressure number.
