Melt Electrowriting (MEW)
The optional MEW module of BS3.1 combines pneumatic extrusion and high-voltage induced fibre deposition for particular thermoplastic materials. So far PCL 50,000 can be printed.
In contradiction to Melt Electrospinning (MES) Melt Electrospinning Writing deposits each fibre in a regular manner accordingly to the CAD model.
The Melt electrowriting module extends the standard configuration of the instrument by a special tray with embedded electrode, a high-voltage generator and security measures. The minimum strut width is in the range of 10…20 Micrometers. Left side picture shows the print setup with nozzle electrode, the right side shows the high-voltage generator.
