The use of microreactors is one of the latest innovations in the chemical and pharmaceutical industry. One of the main issues in the fabrication of microreactors is the use of a proper technique to obtain the micro channels, in order to give them the desired shape and section so that reactants flowing inside are correctly fed through inlet branches and mixed. This paper proposes an experimental study on glass machining for the fabrication of microreactor channels through the use of a CO2 laser source. The aim of the experiments is to analyse the effects of a CO2 laser beam on glass and to study the influence of process parameters, such as laser power, focal distance and scanning speed, on the shape of the channel section and on the surface finish.

Abstract
The use of microreactors is one of the latest innovations in the chemical and pharmaceutical industry. One of the main issues in the fabrication of microreactors is the use of a proper technique to obtain the micro channels, in order to give them the desired shape and section so that reactants flowing inside are correctly fed through inlet branches and mixed. This paper proposes an experimental study on glass machining for the fabrication of microreactor channels through the use of a CO2 laser source. The aim of the experiments is to analyse the effects of a CO2 laser beam on glass and to study the influence of process parameters, such as laser power, focal distance and scanning speed, on the shape of the channel section and on the surface finish.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
