Do my files get uploaded?

No. Everything runs in your browser. The file never leaves your computer, so it works for client files and unreleased designs too.

Does it keep the pose?

It uses the pose the model is saved in (usually the T-pose or rest pose). Animations aren't used. Pose it in Blender first if you want a different one.

Old FBX files won't open.

We read FBX version 7 and newer, binary or text. Very old files (FBX 6 and earlier) need re-saving from Blender or the FBX Converter.

Got a character or prop as FBX? Drop it in. We read its units, stand it up for your printer and save it as STL.

Good to know

GuideFrom Blender to a 3D printSet Blender to millimetres, make the mesh solid, check that walls are thick enough, then export an STL.

Why FBX models come out the wrong size

FBX files say how big one unit is. Blender, Maya and 3ds Max all use different defaults. We read that value, so most files come out right.

If it's still off by 10 or 100 times, pick the unit by hand or type the height you want.

What comes across

	In the FBX	In your STL
Shape	Yes	Yes, in its saved pose
Materials and textures	Yes	No
Bones and animation	Yes	No

Pose the character in Blender first if you want it printed doing something.
