                         space and weight are restricted, present in the aerospace, 
                         automotive and naval sectors. The study of new technologies to 
                         produce compact heat exchangers has grown considerably in recent 
                         years. One of the technologies that presents a great potential for 
                         this application, and which has been little explored, is additive 
                         manufacturing. This work presents a feasibility analysis of 
                         additive manufacturing to produce polymer compact heat exchangers. 
                         Experimental tests in prototypes, using the Fused Deposition 
                         Modeling (FDM) and Selective Laser Sintering (SLS) technologies, 
                         were taken, aiming to evaluate the thermal and hydrodynamic 
                         behavior of the heat exchangers. They were tested with air at room 
                         temperature and water at high temperatures, over a wide Reynolds 
                         number range, from laminar to turbulent flow, comprising 150 
                         experimental tests. Additionally, a mathematical model to predict 
                         the thermal behavior of the prototype was developed and validated 
                         experimentally, the theoretical and experimental heat transfer 
                         rate showed good agreement, with an average error of approximately 
                         3.5%. Even with low thermal conductivity of the polymer, an 
                         overall heat transfer coefficient of 194 W/m2K was achieved.",
