Disclaimer

⚠ Read before use
Simpel3D converts file formats. It does not guarantee the accuracy, printability, or structural safety of converted files. Always verify converted files before using them in print, manufacturing, or any safety-critical application.
General Disclaimer
The information and output files produced by Simpel3D ("the Service") are provided for informational and practical convenience purposes only. While we strive to provide accurate format conversions, we make no representations or warranties of any kind — express or implied — about the completeness, accuracy, reliability, suitability, or availability of the Service or its outputs.
No Warranty on Output Files
Converted files are produced by automated software processes, including WebAssembly-compiled libraries with known technical limitations. We explicitly do not warrant that:
- Converted files are geometrically accurate representations of the original input
- Converted files are printable without errors on any specific printer or slicer
- Converted files are manifold, watertight, or free from mesh errors
- Converted files will produce structurally sound physical objects when printed
- All parts of a complex assembly will be present in the output
- Material properties, tolerances, or colour information will be preserved
- Files above approximately 60MB will convert without data loss
Technical Limitations You Should Know
STEP / IGES Tessellation
STEP and IGES are parametric CAD formats. Converting them to mesh formats (STL, OBJ, 3MF) is a lossy process — smooth curves are approximated by triangles. Very small or very precise parts may lose detail. Always compare the output visually against the original before use.
Large Assembly Limitation
Files above approximately 60MB may return partial or empty geometry due to WebAssembly memory limits in the browser. The Assembly Splitter feature attempts to process individual parts separately, but some parts may still be skipped if they exceed memory limits individually.
Browser-Dependent Behaviour
Conversion results may vary between browsers due to differences in WebAssembly heap size limits. Safari is more restrictive than Chrome or Firefox. We recommend Chrome or Edge on desktop for large files.
Safety-Critical Use Prohibition
DO NOT USE FILES CONVERTED BY SIMPEL3D IN SAFETY-CRITICAL APPLICATIONS WITHOUT INDEPENDENT PROFESSIONAL VERIFICATION. THIS INCLUDES BUT IS NOT LIMITED TO: STRUCTURAL COMPONENTS, MEDICAL DEVICES, AVIATION PARTS, VEHICLE COMPONENTS, PRESSURE VESSELS, LOAD-BEARING STRUCTURES, OR ANY APPLICATION WHERE FAILURE COULD RESULT IN INJURY, DEATH, OR SIGNIFICANT PROPERTY DAMAGE.
3D printing is a manufacturing process with inherent variability. Any use of converted files in applications involving personal safety is entirely at your own risk.
Intellectual Property Disclaimer
Simpel3D does not verify the intellectual property status of files processed through the Service. By using the Service, you represent and warrant that you own the files you process, or have the legal right to convert and distribute them.
Third-Party Tools & Slicers
Simpel3D is not affiliated with any slicer or printer manufacturer and makes no warranty that converted files will function correctly with any specific third-party application such as Cura, PrusaSlicer, or Bambu Studio.
No Professional Advice
Nothing on simpel3d.com or produced by the Service constitutes engineering, manufacturing, legal, or professional advice of any kind. For safety-critical applications, always consult a qualified professional.
Your Responsibilities — Checklist
- Verify the geometry of converted files visually before use
- Run converted files through a mesh repair tool (e.g. Meshmixer, Netfabb) for critical applications
- Confirm you have the legal right to convert any file you process
- Do not use converted files in safety-critical applications without independent verification
- Test print at small scale before committing to large print runs
- Check that your slicer correctly interprets the converted file before printing
Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SIMPEL3D SHALL NOT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF CONVERTED FILES, INCLUDING BUT NOT LIMITED TO: FAILED PRINTS, WASTED MATERIAL COSTS, DAMAGED PRINTERS, PROPERTY DAMAGE, PERSONAL INJURY, OR FINANCIAL LOSSES — EVEN IF SIMPEL3D HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
