8.0 Supplementary Information
Levelling
This refers to the process of ensuring the nozzle is always the
same distance from the print bed to ensure accurate extrusion,
good base surface finish and adhesion. Robox® performs the
operation automatically in both dimensions, by adjusting the
level of the gantry and continually adjusting its height as the
bed moves back and forth.
Linear Bearing
This is a mechanical component which is used to constrain
motion to 1 DoF (Degree of Freedom) - i.e. it can only move
along a rail and cannot rotate. Linear bearings are used in the
bed, Z carriage and X carriage to ensure the accurate position
of the printhead.
Macro
This refers to a sequence of GCode instructions which are
executed sequentially to perform a particular function.
Manifold
This is a term which is used to describe whether a surface
model contains any gaps in its surface - i.e. whether it is
‘watertight’. Non-manifold surface models may produce errors
in slicing, as the software is unable to define that edge.
MEK
Methyl ethyl ketone, also known as butanone is commonly
used as an industrial solvent and polymer cement. It can be
used for joining together printed parts and ‘vapour smoothing’
but must be used with care, as it can irritate skin and eyes. See
section 6.3.
Mesh
See 3D Model.
Micro-Manufacturing
A term used by us to describe the manufacture of objects on
your desktop - i.e. a personal factory. Also used in industry to
describe the manufacture of very small objects.
Microstepping
A method of increasing the number of steps per rotation of a
stepper motor by varying the supply to the coils, allowing for
increased resolution and smoother operation.
Model
See 3D Model
Nozzle
This is the part of the printhead through which material is
extruded. Robox® has two nozzles of different diameters -
0.3mm and 0.8mm - with the smaller being used for fine details
and the exterior surface of the part, and the latter being used
for infilling the part at high speed by extruding a large amount
of material at once.
