2.0 Overview
2.4 How It Works
2.4.1 3D Printing
When Robox® is using the 3D printer head, it uses a technology known as Fused
Filament Fabrication (FFF). This works in a similar way to a hot-melt glue gun -
using plastic filament instead of glue sticks.
The feedstock for the print head is 1.75mm thermoplastic filament which is
supplied on a reel for installing into the printer. This is then fed to the head via a
Bowden tube using the extruder, which contains two contra-rotating feedwheels
to grab hold of the filament, and push it along the tube to the head.
When the filament reaches the head, it is extruded out of a hot nozzle, which
melts the plastic and can control the diameter of the extrudate by using two
different size nozzles. This twin nozzle arrangement allows for highly detailed
outer surfaces of the print (those that are visible), alongside the larger nozzle
which is used for filling in parts quickly.
The printer head is mounted to a quick-release carriage, known as HeadLock™
which is constrained by a Cartesian axis system, allowing the head to move in 3
dimensions.
The included AutoMaker™ software translates your 3D design files (in .stl or .obj
format) into machine coordinates that Robox® can understand. It does this by
‘slicing’ the 3D model into it’s individual layers, and then sending each slice (or
layer) to the printer, one at a time.
To produce a part, the molten plastic is laid down one layer at a time, and the
head moves up by a small amount (as little as 0.02mm!) at the end of each layer.
This allows fully-solid plastic parts to be constructed, with the quality of the
surface finish being determined by the height of the individual layers (quality
setting).
Robox® SmartReels are available in a variety of materials, finishes and colours
and they are automatically recognised by the machine, setting all of the
appropriate parameters for you. All you need to do is pick one, choose what
quality you’d like your model and hit print!
