Get perfect settings for your print
Upload your 3D model and we'll analyze it and recommend slicer settings tailored to your exact setup — with plain-English explanations.
Prefer a single STL file when possible
STL files contain exactly one object, making analysis straightforward and reliable. If you have a single part to print, STL is your best friend.
.3mf files are powerful but have gotchas
.3mf files can contain multiple objects arranged on a build plate, or even multiple build plates. If your .3mf has more than one object or plate, our analyzer may misread the geometry — treating multiple objects as one suspended mass, which causes false overhang warnings and inaccurate support estimates. For best results, export individual parts as separate files.
Make sure your model is print-ready
If you designed the model yourself or downloaded it from a repository, double-check it's a solid, watertight mesh with no holes. Tools like Meshmixer (free) or PrusaSlicer's built-in repair can fix most issues automatically.
One part at a time
Even if you plan to print multiple parts together, analyze them one at a time here. Each part may need different settings — especially if they vary in size, overhang complexity, or required strength.
File size and complexity
Very large or highly detailed files (over 50 MB or 1M+ triangles) may take a moment to analyze in your browser. This is normal — we're doing real geometry math on your device.
