classdef resinparam
    % RESINPARAM holds thickness measurements and gets curing properties
    %  This should hold a full set of thickness and exposure measurements
    % and will calculate and hold the curing properties such as the
    % critical exposure and depth for the resin.  Mechanical properties
    % such as the change in Young's modulus or volumetric strain can also
    % be calculated and stored.
   
    properties
        tArray        % Linear array of exposure times from measurement(s)
        hArray      % Corresponding array of print heights from measurement (m)
        critD       % critical depth (m)
        critE       % critical exposure (J/cm^2)
        critT       % critical time (s)
        K           % Polymerization constant
        phi_c       % Polymerization threshold
