FAQ
Frequently Asked Questions About STEP to STL Conversion
Have questions about converting STEP to STL? Find answers below or contact us for support.
1
What does STEP to STL conversion do?
STEP to STL conversion transforms your STEP (Standard for the Exchange of Product Data) files into STL (Stereolithography) format. STL is the most widely used format for 3D printing, and our converter ensures all geometric data is preserved during the conversion process.
2
How do I convert STEP to STL?
Converting STEP to STL is simple: click the 'Upload a File' button and select your STEP file. The conversion will start automatically, and once complete, you can download your STL file. The entire process takes just a few seconds.
3
Do I need special software to convert STEP to STL?
No software is needed to convert STEP to STL. Our converter is completely web-based and works in any modern browser on Windows, Mac, Linux, Android, iOS, or mobile devices.
4
What is the difference between STEP and STL formats?
STEP is a CAD file format that includes precise geometric data, curves, and surfaces. STL is a simpler format containing only triangular mesh data. Converting STEP to STL tessellates the surfaces into triangles for 3D printing.
5
Can I convert STEP files from CAD software?
Yes! Our converter handles STEP files from CAD software like SolidWorks, AutoCAD, Fusion 360, and CATIA. The conversion preserves geometric accuracy for 3D printing.
6
Is my STEP file safe when converting to STL?
Yes, your privacy is important. We don't store your STEP files after conversion. Converted STL files are stored for 4 hours, then automatically deleted.
7
What is the maximum STEP file size I can upload?
You can upload STEP files up to 100MB. Larger files may take longer to process, but our converter handles files of various sizes efficiently.
