Abstract

The ongoing trend for miniaturization demands research in the field of micro-extrusion. This work compares two techniques for manufacturing micro-dies; mechanical manufacturing and laser ablation. A micro-die needs to fulfill requirements such as fast nozzle exchange and high accuracy. The nozzle channel needs to have a diameter of less than 0.5 mm, a high quality and high aspect ratio. The disadvantages and advantages of both techniques are discussed while experimental data supports the discussion. The results go well with the expected behavior based on the nozzle channel's geometry. Laser ablation is the tool of choice when manufacturing micro-dies for extrusion.
