Conventional CAD FEA assumes a homogeneous material
FFF printed parts are not homogeneous materials
Every printed part contains perimeters, infill and layer interfaces. These structures fundamentally change how forces travel through the part. This is why conventional CAD/CAE simulation often fails to predict real-world behavior.
Built specifically for FFF 3D printing
1) Import your STL
2) Choose print settings
3) Apply forces and fixed points
4) Predict weak locations
5) Optimize before printing
Instead of analyzing an idealized CAD model, Slicedog automatically builds a finite element model from your print settings. Perimeters, infill and top/bottom layers are simulated separately, reflecting the real mechanical behavior of FFF printed parts.
Engineering questions Slicedog helps answer
Can this 3D printed part survive the expected load?
Will changing print orientation improve strength?
Is the current infill and perimeters sufficient?
Where will the printed part fail first?
Are weak points of the CAD design the same as the weak points of the printed part?
Will carbon fiber actually solve the problem?
Validated againts physical testing
Our simulation results were independetly verified using physical load testing performed at the university.

Comparison with physical load testing
Physics-based material model
Each segment (perimeters, infill, top/bottom) has different anisotropic strength characteristics
Pressure test of 3D-printed infill used to determine anisotropic strength characteristics (different strength in X, Y, and Z directions).
Strength simulation is slicer-independent. Slicedog validates your print settings, perform the analysis and lets you continue using your prefered slicer to generate g-code.

FAQ
Frequently asked questions about Slicedog
Can Slicedog replace conventional FEA?
For FFF printed parts, yes.
Slicedog replaces conventional CAD simulation by using a manufacturing-aware material model built specifically for FFF printing. It also replaces the complex manual workflow typically required in general-purpose CAE software by automatically generating the simulation model directly from your print settings.
The result is engineering-grade strength validation in minutes instead of hours.
Will Slicedog fit into my existing workflow?
Yes. Slicedog integrates into your current CAD → STL → slicer workflow. It imports your existing print settings, performs the strength simulation, and lets you continue generating standard G-code using your preferred slicer.
Which applications is Slicedog designed for?
Slicedog is built for functional FFF printed parts where mechanical performance matters, including production tooling, fixtures, machine components, spare parts and engineering prototypes.
How accurate is the simulation?
Slicedog uses a physics-based material model that has been experimentally validated against physical load testing. The simulation is specifically developed for FFF printed parts rather than homogeneous solid materials.
Which printers, slicers and materials are supported?
Slicedog is printer-independent and works with the most widely used FFF workflows, including Cura, OrcaSlicer, Bambu Studio and PrusaSlicer. It supports the most common engineering materials, with additional material models available for enterprise customers.
Can Slicedog run offline?
Yes. Enterprise deployments can be installed entirely offline, making Slicedog suitable for companies working with confidential designs or operating in secure environments.
