Materials

• Plastics• Thermoplastics –acrylonitrile

butadiene styrene (ABS), nylon (polyamide) (PA), polycarbonate (PC), polylactic acid* (PLA), polycaprolactone* (PCL), as well as ABS/PC and other polymer blends

• Thermosets – not commonly used because these can damage instrument

Fused Deposition ModellingFDM• Pros:

• Relatively strong materials• Make complex geometries• Material cost is reasonable

•Cons:• Poor surface finish (solvent wash)• Little material variety
