Millifluidics VS Microfluidics

The use of 3D printing in research industry has increased due to the efficiency and reliability of 3D printers. 3D printing technologies have advance throughout the recent years. The main advancement of 3D printers is the level of detail.  For this article we are specifically talking about 3D printing Millifluidics and Microfluidics.

Besides the unit of measurement, millifluidic and microfluidic have drastic difference and effect on scientific research. If a 3D printer and its resin are limited to printing millifluidics, you may run into several problems. One common problem with millifluidic is that you are using more material for a testing. In some cases you are extremely limited with materials for specific projects.

For example, you minimum channel sizes for millifluidics are 1000μm. A printer that is capable of printing microfludics can easily print channel sizes under 500μm. As a result, you would need to run more material through a millifluidic chip to have accurate results.

For our testing with the M50 from CADworks3D and the resin, BV-007 Clear, we were able to print channel sizes at 100um for a basic microfluidic chip.

Not only does M50 offer these precise details, it also offers you the flexibility of printing millifludics, if it was required for other projects. However, in most cases printing microfludics will save you in lab material and printing material.

Another major problem you run into with millifluidics, is your chip design are much more limited. You may find that certain CAD designs will work for microfluidics but won’t be printed on a printer limited to millifluidics.

Overall, this will accelerate research by allowing more complex designs to be printed and used for analysis.
