Bill of Materials

To cast an actuator with one of the laser cut molds, the following is needed:

Materials

• Liquid silicone (Ecoflex 0030 or 0050)
• Silicone glue (Sil-Poxy)
• Non-stretch fabric (in a material that will absorb the liquid silicone, e.g. cotton)
• PVC tubing (ID/OD 1.5/3mm) (Silicone tubing can also be used, but is hard to push it into the actuator, as it is softer. It is, however, easier to fit onto a syringe, valve, pump, and Y connector)
• Mixing container (with volume indication if a scale is not used)
• Stirring stick
• Bamboo skewer (with an approx. diam. of 3mm)
• Cigarette lighter
• Rectangular piece of wood (a little larger than the mold)

Tools

• Pair of scissors
• X-Acto knife and ruler (optional)

Equipment

• Oven (optional) [Note: do not use an oven that is also used for food]
• Vacuum chamber (optional)
