the efficiency of the process, providing great advantages for
mass production.
However, one main issue of continuously printing is that
significant downtime is wasted due to two key reasons [1],
[2], as shown in Figure 1. First, during the preparation on a
new print job or removal of the completed print job, the FFF
printers are unutilized, without human interference [2].
Second, there are various quality problems of the parts that
are fabricated using the FFF process, which potentially lead to
failure printing [3]. To make matters worse, the machine time
is wasted if the defective prints are not stopped. These two
issues cause a major hurdle to scale FFF 3D printers. In the
current practice, it relies heavily on human intervention to
monitor the printing conditions, remove the current print,
The Print needs to be manually removed
before the next print can start.
Current Practice
(a)
Time is wasted if the defective
print is not stopped
Our Proposal
(b)
Figure 1. The research motivation. A fleet of FFF 3D printers for 24-hr continuous printing provides great advantages. However, in the
current practice, to achieve continuous printing is challenging as it requires continuous human intervention for two key reasons. First,
the print must be removed before the next print can start. Second, time is wasted if the defective print is not stopped. Hence, in this
article, we propose a robotic solution to address these issues.
