Design takeaway

How to apply

Before finalizing a design using 3D-printed polymers, subject prototype samples to accelerated aging tests that mimic the expected environmental conditions of the product's use, and re-evaluate key mechanical properties.

Project actions

01When choosing materials for your design project, consider how the environment will affect them over time.
02If your project involves outdoor use or significant temperature/humidity changes, test your 3D printed parts under those conditions.

Method & Evidence

AimTo quantify the impact of simulated environmental shock conditions (temperature and humidity) on the tensile properties of various 3D-printed polymers.

MethodExperimental testing and material analysis

ProcedureSamples of ABS, HIPS, PLA, and ASA were 3D printed and subjected to a 7-day environmental shock cycle involving fluctuating temperature and humidity. Post-exposure, static tensile testing, Charpy impact testing, and scanning electron microscopy (SEM) were performed to evaluate structural and mechanical changes. Chemical property analysis was conducted using FTIR and TGA.

Paragraph starter

The performance of 3D-printed materials can be significantly impacted by environmental factors. Research indicates that even short-term exposure to shock conditions, such as rapid fluctuations in temperature and humidity, can lead to a measurable degradation in tensile properties, with the extent of this degradation varying by polymer type. This suggests that for design projects requiring durability in variable climates, material selection must be informed by environmental stress testing to ensure product reliability and longevity.
