8.0 Supplementary Information
PP
Polypropylene - a ‘waxy’ flexible thermoplastic which can be
used for 3D printing, however it is particularly susceptible
to shrinkage and warping issues due to its large thermal
expansion coefficient.
Print Head
This is the ‘end-effector’ of Robox® which can perform a
number of different functions depending on the model. The
standard model is a single material, dual nozzle FFF head for
producing 3D prints from a range of thermoplastic filaments.
PFA
Perfluoroalkoxy alkane - A flouropolymer with similar properties
to PTFE.
PTFE
Polytetrafluoroethylene (Teflon®) - A high temperature
engineering thermoplastic with an extremely low coefficient of
friction - used to line the filament path to the head.
Pulley
More specifically - a timing pulley - used for translating
rotational motion into precise linear motion. The pitch of
the belt and the number of teeth on the pulley defines the
resolution.
Purge
When switching between two dissimilar materials, it is
important to remove the old material from the head
completely to prevent blockages. Purge is a routine that
chooses an intermittent melt point and forces through material
to effectively switch between materials - see section 7.2.1.
PVA/PVOH
Polyvinyl Alcohol - A water-soluble filament used as 3D printing
material, often for dissolvable support. See section 6.2.1.
QuickFill™
This refers to the twin nozzle system used by Robox® for
reducing overall print times. By using a fine and fill nozzle, the
exterior of the part can be produced slowly and carefully by the
smaller nozzle, and then the inside can be filled quickly with the
larger nozzle.
Raft
A technique used to prevent warping. Parts are built on top
of a 'raft' of disposable material instead of directly on the
build surface. The raft is larger than the part and so has more
adhesion. Similar to brim in functionality.
Rail
A hardened and ground steel round bar used for constraining
linear motion to one DoF.
.ROBOX
A Robox® file - contains an AutoMaker™ project which includes
your layout of objects on the print bed and all associated print
settings and slicing parameters.
