8.0 Supplementary Information
8.2.3 Printing
• How do you support overhangs in the print?
AutoMaker™ automatically generates easy to remove support when printing
with the single material (but dual nozzle) head. Because of the HeadLock™
system, switching to a dual material head with dual extruders in future
will be a snap. This upgrade will allow Robox to print with dissolvable
support materials such as PVOH (Polyvinyl Alcohol) and HIPS (High Impact
Polystyrene) - see section 6.2.
• Is ABS safe to print with?
Molten ABS is not actually a toxic material, as some comments suggest.
There are some research projects that suggest there are ultrafine airborne
particles which are released when the plastic is melted, and the current
advice is to suggest “caution when operating in inadequately ventilated
or unfiltered indoor environments.” Just like mobile phone radio waves
the research is inconclusive at this stage, but has captured a lot of media
attention.

• If I put two items on the bed, is it possible to print one by one rather than
both together?
It is possible to print one at a time, but because Robox builds vertically, a
large exclusion zone is required around object 1 to prevent the head bashing
into object 2 – this is possible with very small items.
• How many parts can be printed from one SmartReel™?
This is obviously completely dependent on the size of the model, it’s fill
density and the quality setting chosen. The AutoMaker™ soware will provide
an estimate of how long the print will take, as well as how much material will
be required (while also checking there is enough material available on the
reel). Each reel holds ~650g of print material.
