TG/DTG/DTA/DSC as a tool for studying deposition by the sol-gel process on materials obtained by rapid prototyping

In rapid prototyping (RP), building 3D physical prototypes involves the addition of material in layers. The sol-gel route is an alternative to produce multicomponent oxide materials with chemical, physical and thermal properties that cannot be obtained by other processes. The sol-gel method allows for the preparation of coatings on several kinds of materials, directly influencing the materials’ properties. In this work, metal oxides were prepared by the sol-gel process and deposited further by dip-coating technique on ABS and Nylon substrates obtained by RP. The resulting coating presented good adhesion to the substrates. The obtained materials were characterized by scanning electron microscopy (SEM) and thermal analysis (TA).
