ABSTRACT: The purpose of this work is to present static and modal analysis of structure machine of a
portable 3-D printer (Fab@CTI) and to propose some structural modifications. The structure of Fab@CTI was
initially based on project of Fab@Home, whose propose is offers a desktop 3-D printer open-source. Currently,
the desktop 3-D printer Fab@CTI presents adjustments related to
