Will PTFE be the next 3D printable material?
IDTechEx have been wondering how long it will take for more plastics to become available for 3D printing. The range is currently very limited, but new materials are becoming available all the time. Wacker, with their ACEO brand, recently launched a machine to 3D print silicone, which they will be demonstrating at IDTechEx Show! 3M are looking to offer print-on-demand solutions for spare and custom parts. In particular, this fluoropolymer 3D printing service would be used for parts with particularly complex geometries. This "service bureau" business model is becoming increasingly common as the technologies to print the materials become more complicated and the materials become more difficult to handle. Anyone can extrude PLA at home, so companies can sell thermoplastic extruders. Companies like Organovo offering 3D cell printing or Impossible Objects offering carbon fibre reinforced plastic 3D printing, have complicated equipment, which they keep in house, and sell parts they produce.

Screw theory
A spatial displacement of a rigid body can be defined by a rotation about a line and a translation along the same line, called a screw displacement. This is known as Chasles’ theorem. The six parameters that define a screw displacement are the four independent components of the Plücker vector that defines the screw axis, together with the rotation angle about and linear slide along this line, and form a pair of vectors called a screw. For comparison, the six parameters that define a spatial displacement can also be given by three Euler Angles that define the rotation and the three components of the translation vector.
