This white paper was motivated by claims of superior material properties by FFF (fused filament fabrication) competitors despite internal Stratasys testing that demonstrated otherwise. This incongruity between published and demonstrated specifications stems from differences in the toolpaths and build orientation of mechanical test specimens between Stratasys test methods and the competitor’s.
When switching from the standard toolpaths used by Stratasys to the optimized unidirectional toolpaths used by the competitor. Stratasys FDM® Nylon-CF10 demonstrated the results that follow:
3D printing mechanical samples with unidirectional toolpaths is appropriate to show the maximum strength of a carbon fiber filled material, but is not representative of the material strength within the typical FDM 3D printed part.
Discover how optimized unidirectional toolpaths led to impressive improvements in heat deflection, tensile modulus, and yield strength for Stratasys FDM® Nylon-CF10, showcasing the potential for enhanced FDM 3D printing materials.
Stratasys pioneered Fused Deposition Modeling (FDM), a groundbreaking patented innovation that has become synonymous with quality and precision. Meanwhile, Fused Filament Fabrication (FFF), based on the same Stratasys-developed technology, operates without patent limitations and embraces open-source principles.
Although the naming differs, the fundamental principles powering FDM and FFF remain similar. Both methods employ molten thermoplastic material extruded through a nozzle, constructing objects layer by layer.
These materials showcase exceptional mechanical attributes, heat resilience, and chemical durability, rendering them ideal for demanding applications within sectors such as aerospace, automotive, and healthcare.
FFF 3D printers typically support a narrower range of materials and thermoplastics, which are more commonly used in hobbyist and consumer-grade applications.
This white paper uncovers the truth behind Stratasys' internal testing and competitor claims in FDM.
