Microfluidics Manufacturing: Micromilling

Micromilling in Microfluidics:Using small cutting tools to create microfluidic architectures.

It is a mechanical method, in which we use  small cutting tools to remove the materials from a specific part of the microfluidic architecture.

All thermoplastics can be subjected to micromilling and can be used only on hardened materials. The structure resolution depends on the tool dimension; it can go down to 25μm.

PDMS structure cannot be obtained directly by this method. The replica of the design can be machined and the mould(are reusable) can be casted in order to get PDMS devices.

Technique: A computer is used to control the position of the tool  and the cutting of the structures.The milling time,depends on the milling structure, and can vary from minutes to hours .

The advantage of this technique is that it does not affect the polymeric material by UV radiation or heating, but it creates stress near the cut structures that can be avoided by heating and slow cooling.
