1.1.2 Extrusion Safety:
Never extrude PVC or any plastic whose type is unknown. The fumes could be lethal! ProtoCycler currently
supports PLA and ABS. An exciting experience the ProtoCycler provides is the ability to experiment with new
materials and colours through our software. It is important that you understand the material you are extruding and
what is released when thermally broken down. If the material will release toxic fumes then you should not extrude
it. For instance PVC will release chlorine gas and under no circumstances should you try to extrude it with the
ProtoCycler. ABS on the other hand is commonly used in 3D printing – but, for safety reasons, still requires proper
ventilation to the outside.
1.2 ProtoCycler Layout
Before we go any further, let’s learn some key terminology that will be used throughout this guide. The following
images outline the key areas of importance. Many of the terms are intuitive in meaning.
