Process Temperature Control Strategy in FDM 3D Printers
In recent years rapid prototyping (FDM) technology has developed rapidly. However, there are few researches related to electronic control systems and the printing circuit's own circuits, geometry and size.
In these 3D printers, the printing process is very susceptible to thermal damage, which may have consequences on mechanical properties and may cause fracture or even total loss of the prototype. These problems can be mitigated through efficient temperature control during the prototype manufacturing process to ensure acceptable energy levels.
The production conditions to be controlled are basically limited to controlling the printing temperature during the process.
Process monitoring provides information to the control system and, as defined limits are reached, control systems can correct these variations even during the production process. The control system can act to raise or lower the temperature thereby performing spatial temperature control by means of the pixel warming table and temporal temperature control by means of a layer / print layer information storage system.
