8.3 Glossary of Terms
This section contains a comprehensive glossary of frequently used 3D printing
and custom manufacturing terms and jargon.
1st Layer
This is the first layer of plastic which is laid down on the build
plate at the start of a print. It is the most important layer of a
print, as it used for adhering the part to the bed.
3D Model
A mathematical representation of the three-dimensional
surface of an object (in the case of Robox®) constructed using
triangles, also known as a mesh. There are many file formats for
this, with Robox® currently accepting .stl and .obj.
3DP
Abbreviation of 3D Printing
ABS
Acrylonitrile Butadiene Styrene, a thermoplastic used as a
3D printer material. It produces tough, impact-resistant parts
which make excellent functional prototypes. It can be tapped,
sanded, painted and vapour polished allowing for high quality
finishing.
Accuracy
Generally used to describe the theoretical accuracy of the
motion system. This is calculated from the step accuracy of the
stepper motor used for control and the pitch of the leadscrew /
belt. See section 2.2 for accuracy specifications.
Acetone
A colourless, flammable liquid also known as propanone - a
solvent which will dissolve ABS and can be used as a cement
for gluing parts together. It can also be used for ‘vapour
smoothing’ see section 6.3.
Additive Manufacturing
(AM)
The process of constructing an object by selectively adding
material, rather than starting with a block of material
and cutting away what you don’t need - see subtractive
manufacturing.
Ambient Temperature
This refers to the air temperature inside the build chamber
during the print. Maintaining this at a stable temperature
can help to reduce warping of parts as they are produced by
encouraging even cooling.
.AMF
AMF serves is an alternative to the STL file format based on XML
which supports units, colour, textures, curved triangles, lattice
structures, and functionally-graded materials—features that the
STL format does not support.
