Polymers
Polymers are often used in medical and biotech devices (e.g. for meshes, filters, tubes, microchannels) and in the microelectronic and sensor industries for insulating layers in multi-level devices. In all these cases, the high precision required has to be matched to high quality (i.e. lack of damage and burrs, no melting, high reproducibility). Other high precision use of polymers include their use as deposition masks in coating systems.
Many types of polymers can be laser machined, the most common ones being polyimide (PI), polycarbonate (PC) and polyester (PET). Other polymers include PMMA, PTFE, SU8, other photoresists and acrylics.
