mechanisms, should be considered. These modifications could
help maintain thermal stability throughout extended printing
tasks, thereby improving part quality and reducing the incidence
of thermally induced print defects

Blockboard Sheet Enclosure

Figure 9 illustrates the ambient temperature profile recorded
within a blockboard enclosure throughout a 200-minute period of
FDM 3D printing process. Evaluating the enclosure's thermal
stability is essential in determining its suitability for maintaining
optimal printing conditions, particularly for thermally-sensitive
filaments, like ABS.

Figure 9: The ambient temperature reading for blockboard sheet
enclosure

The graph illustrates a rapid rise in ambient temperature,
beginning at approximately 36°C and stabilising near 64°C within
the first 30 minutes. This is followed by a plateau phase, where
the temperature remains relatively steady, fluctuating minimally
between 63°C and 65°C, for roughly 120 minutes. This stable
thermal behaviour suggests that the plywood enclosure offers
effective heat retention, contributing to a controlled environment
