Exporting 3D Models
In addition to G-code, 3dSynth can export your design as a 3D mesh file.
Mesh Sculptor and Texturize use Export Mesh as the primary toolbar button (binary STL). The caret picks Draft / Standard / High / Ultra. Those modules do not emit G-code. Texturize quality and GPU preview: Preview and export.
For toolpath modules, click the download button (↓) next to "Export G-Code" to access STL / OBJ / glTF of the preview path.
Export Formats
STL (Binary)
Standard Tessellation Language
The most widely supported 3D printing format. Use this when you want to:
- Import into a slicer (Cura, PrusaSlicer, etc.) for multi-material prints
- Combine with other models before printing
- Share the model on Thingiverse, Printables, etc.
- Open in CAD software for further editing
OBJ
Wavefront Object Format
A universal 3D format supported by almost all 3D software. Ideal for:
- Importing into Blender, Maya, Cinema 4D, etc.
- Rendering high-quality images or animations
- Game development workflows
glTF / GLB
GL Transmission Format
The modern "JPEG of 3D" — compact, efficient, and web-ready. Best for:
- Web-based 3D viewers (Sketchfab, model-viewer, etc.)
- AR/VR applications
- Three.js and WebGL projects
- Sharing with embedded materials and colors
Animated glTF
Layer-by-layer reveal animation
Creates an animated 3D file that shows your model "printing" layer by layer. Use it for:
- Social posts — play the build sequence in a glTF viewer
- Product pages and marketing stills or renders
- Web embeds with playback controls
- AR experiences showing the build sequence
Exporting animations
When you want a layer-by-layer reveal (the model building up over time in an animation):
- Click the download button (↓) next to "Export G-Code" to open the export dropdown.
- Choose Animated glTF (or the equivalent animation option in the list).
- A settings dialog appears — pick the up-axis, origin, and detail level, then Export GLB.
- Each frame of the animation reveals more layers of the toolpath, so when played back it looks like the print is being built.
Use this in any viewer that supports animated glTF, or render a turntable from the GLB in Blender.
Animated glTF settings
Animation export options
Up Axis- Which world axis points "up" in the exported file. Pick Z for most 3D-printer-oriented tools, or Y for Blender's default orientation. Choices: X, Y, Z.
Origin Point- Where the model origin (the point the viewer rotates around) is placed relative to the bounding box. Choose between −X/X, −Y/Y, and −Z/Z to put the origin on any face of the model's bounds.
Detail Level- Number of tube segments used to build the animated toolpath. Higher values produce a smoother mesh but a larger file. Presets: Low (10 000), Medium (50 000), High (150 000, default), Ultra (300 000). You can also type a custom value between 1 000 and 1 000 000.
How to Use
Mesh Sculptor / Texturize: click Export Mesh. Optional: pick quality from the caret (Texturize defaults to High). Slice the STL in another app.
Toolpath modules:
- Create your design using the profile editor and effects
- Click the download button (↓) next to "Export G-Code"
- Select your desired format from the dropdown
- The file will download automatically
