FDM Print Orientation: Upright Printing Can Reduce Tensile Strength by 50%

The orientation of a part during Fused Deposition Modelling (FDM) printing significantly impacts its tensile strength, with upright orientations potentially leading to a 50% reduction.

Rapid Prototyping Journal · 2019

Key Findings

01Upright print orientation can result in samples up to 50% weaker.
02Optimizing air gap and raster width is essential for strong inter-raster bonding.
03Material choice, such as PEEK over ABS, can increase tensile strength by over 200%.
04Optimal raster angle is material-dependent, with 0° potentially yielding 100% higher strength than 90° in ABS.

Application

Design takeaway

When designing for FDM, prioritize print orientations that avoid stress concentrations along layer lines and consider advanced materials if high tensile strength is a critical requirement.

How to apply

Before finalizing a design for FDM, simulate or test the tensile strength of prototypes printed in different orientations and with various materials to validate performance against requirements.

Project actions

01When planning your FDM print, think about the direction of the forces your product will experience and orient the part accordingly.
02Experiment with different materials available for FDM to see which offers the best strength for your project.

Limitations

The specific optimal parameters can vary between different FDM printers and filament brands, requiring some level of calibration for your specific setup.

Reliability & validity

The validity of the findings relies on the quality and consistency of the reviewed studies. Reliability would be enhanced by replicating the reviewed experiments with specific FDM printers and materials.

Think critically

To what extent does the observed reduction in tensile strength due to print orientation translate to real-world performance failures, and how can design strategies mitigate these risks?

Design Principles

"Optimize part orientation and material selection in FDM to achieve desired mechanical properties, particularly tensile strength."

Understanding how print orientation affects material properties is crucial for designers and engineers when selecting manufacturing processes. This insight allows for informed decisions to ensure product integrity and performance, especially for components subjected to tensile loads.

What This Means for Your Design

How you orient your part when 3D printing with FDM makes a big difference to how strong it is. Printing it standing straight up can make it much weaker.
