Lighting 3D printed parts on fire is a fascinating experiment that reveals the varying degrees of flammability among different materials. This article delves into the results of such an experiment, shedding light on the potential fire hazards associated with various 3D printing materials. The key takeaway is that the additives and composition of the material play a crucial role in determining its flammability.
The Experiment
The experiment involved exposing various 3D printing materials to an open flame and a blowtorch. The materials tested included PLA, PETG, ABS, ASA, TPU, PEBA, HIPS, and HTPLA. The results were eye-opening, to say the least.
PLA's Flame Test
PLA, known for its carbon content, burned readily. However, the type of PLA made a significant difference. PLA+ required a blowtorch to ignite, burning at a higher temperature with a dirty yellow flame. In contrast, HTPLA resisted burning, self-extinguishing after torch treatment. This highlights the importance of material composition and additives.
PETG and TPU's Resilience
PETG and TPU emerged as the least flammable materials. PETG, in particular, did not ignite easily, while TPU required a blowtorch to start burning. These materials seem to be safer choices for applications where fire safety is a concern.
ABS, ASA, and HIPS' Sooty Flame
ABS, ASA, and HIPS, on the other hand, burned with a sooty yellow flame, indicating a higher level of flammability. These materials are more prone to catching fire and should be handled with caution.
TPU's Aggressive Burn
Foam TPU burned the most aggressively, followed by ABS, ASA, and HIPS. This suggests that the structure and composition of the material can significantly impact its flammability.
Implications and Recommendations
The experiment highlights the importance of material selection in 3D printing, especially in applications where fire safety is a concern. PETG and TPU seem to be the safer choices, while ABS, ASA, and HIPS require more caution. The additives and composition of the material are key factors in determining flammability, making it crucial to choose materials wisely.
In conclusion, lighting 3D printed parts on fire is an eye-opening experiment that reveals the potential fire hazards associated with different materials. It underscores the need for careful material selection and handling to ensure safety in 3D printing applications.
