Abstract
A method for authenticating a user of a 3D printer to prevent unauthorized use of the 3D printer includes obtaining a user profile from a set of user profiles, each user profile corresponding to a user and including a stored multi-digit number; prompting the user, by a touch screen interface of the 3D printer, to input a personal identification number (PIN); preventing use of the 3D printer if the PIN does not match the stored multi-digit number; and authenticating the user if the PIN does match the stored multi-digit number. The method includes prompting the user to apply a force to the touch screen interface; detecting an applied force; comparing the applied force to a force threshold value; and preventing use of the 3D printer if the applied force is less than the force threshold value.
