ters after cooling to room temperature. [23] Powder premix: 80 wt% of ultrafine Al (2.5 micron in average) powder, 5 wt% Cu nanopowder (less than 70 nm), and 15 wt% adhesive binder were mixed in 30 ml acetone.Filling: The moulds were filled with the prepared metallic powder paste. When the powder patterns were dry and became solid, the PDMS mould was peeled off.Sintering: The green patterns were placed inside a furnace(Carbolite 2416-tube furnace) filled with Ar gas and heated to 600°C at 5°C/min and then kept for 6 h. The microcomponents were taken out after the furnace was cooled down to room temperature.
