Resumen
[EN]During an FDM production process, there are different external disturbances to the characteristics of the machine that can affect to
the production process. These disturbances will cause the final result differs from the desired one. Moreover, these disturbances,
such as temperature or chamber humidity, are extremely important in case of using biocompatible materials. The use of these kind
of materials with not controlled environment, can cause them to modify or loss of their properties; what will make the product
unusable. Apart from these external disturbances, the conditions of the machine to which the material is subjected must also be
considered, such as temperature, vibrations or extrusion speed. The monitoring of all these data will allow to know the conditions
to which the product was exposed during the process. In this way, it will be able to verify the validity of the final product. For
these reasons, the purpose of this work is to monitor the conditions of production of structures with biocompatible materials by
fused deposition modelling (FDM) technique. This monitoring will allow us to obtain a report that guarantee the technical and
geometrical characteristics of the model and the biomaterial properties. The parameters chosen to be monitored are: Diameter of
filament use, temperature in extrusion nozzle, ambient temperature in closed chamber, ambient humidity in closed chamber. The
obtained results, after collected and analysing the data, present variations of up to 3% in the temperature of the nozzle of the
extruder with respect to set temperature. In the case of the filament diameter the difference with respect to the value provided from
the filament supplier is of 13,7%. In addition, the results show how the ambient humidity in closed chamber has changed by 2
percentage points and the ambient temperature in closed chamber has been increased 6,52 °C with respect to the set values.
