Procedia Structural Integrity · 2024
Key Findings
- 01PLA exhibited the highest water absorption, while ABS showed the lowest.
- 02Multi-material samples with a single layer of ABS had the lowest water absorption.
- 03Mechanical properties (tensile and flexural) of unaged samples varied with the number of ABS layers.
- 04A plateau tendency in mechanical properties was observed for aged samples, indicating a degree of stability despite ageing.
Application
Design takeaway
When designing multi-material components for marine environments using 3D printing, consider optimizing the outer layer material (like ABS) to minimize water ingress and maintain structural integrity.
How to apply
When designing components for subsea or coastal structures, explore the use of multi-material 3D printing, carefully selecting outer materials known for low water absorption and testing for environmental resistance.
Project actions
- 01Consider testing the water absorption of different materials you plan to use.
- 02Investigate how different layering techniques affect the structural integrity of your 3D-printed parts.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Directly tests durability in a relevant environmental condition (seawater).
- +Compares multiple configurations of the multi-material design.
Limitations
The study's findings are specific to the tested materials and conditions; real-world marine environments are complex and can introduce other degradation factors.
Reliability & validity
The use of standardized mechanical testing (tensile and flexural) and a controlled ageing process in seawater contributes to the reliability and validity of the findings regarding material durability.
Think critically
How might the findings on water absorption and mechanical stability be affected by variations in salinity, temperature, or biological fouling in different marine environments?
Design Principles
"Environmental resilience in multi-material additive manufacturing can be enhanced through strategic material selection and layer configuration."
This research demonstrates the potential of additive manufacturing to create robust multi-material components suitable for harsh environments. For designers and engineers, this opens avenues for producing lighter, more integrated parts for marine structures, potentially reducing assembly costs and improving product longevity.
What This Means for Your Design
3D-printed parts made of different plastics can survive in the sea for a while, especially if you put a protective plastic layer on the outside. The strength might change a bit at first, but it stays pretty steady even after being in the water for two months.

Paragraph starter
Research by Duarte et al. (2024) highlights the potential of 3D-printed multi-material parts for marine applications, demonstrating that layered structures of ABS and PLA can maintain mechanical integrity after prolonged seawater exposure. This suggests that additive manufacturing offers a viable pathway for creating durable, integrated components for challenging environments.
