The research was further enhanced with the creation of a
custom-built machine that integrated an SL system with a
dispensing pump to automate the process. Fabrication of
complex, intricately detailed dielectric substrates created with
multiple layers of components and interconnect was now
possible. An example included a functional circuit with a
555-timer oscillator and thermistor in order to illuminate a
Light-emitting diode (LED) at a rate based on the measured
temperature [22].
