Export as STL

Basic requirement: Qubicle Basic Edition + Mesh Module DLC, Utility Module DLC for Compounds.

STL is a file format mostly used for 3D printing. It has very strict rules- for example requiring a watertight mesh. While the original format doesn't support color encoding, there are in fact unofficial color encoding methods that were introduced at a later point. Qubicle uses the Materialise color encoding.

Export Preparations

  • Before exporting your models, ensure that they don't have any hollows. This might be counter-intuitive but hollows increase the poly count. To fill hollows use the corresponding command Modify > Core > Fill Hollows.
  • If you want to export multiple matrices as a single object you don't need to combine them with Boolean Union- use Compounds instead. A Compound is exported the same way as a single Matrix. Select the matrices and use Modify > Compound > Create Compound
  • If you need to export a selection of your model repeatedly compounds are very useful, too. Create a compound of that selection and enter the new compound before export. Only child objects of the active node are exported.

How to export 

  1. If you want to export everything, either select or deselect all objects. If you only want to export a part of your model, select it.
  2. Choose File > Export > STL
  3. Choose a destination and click Save
  4. Adjust export settings and click OK

Export Settings

Single STL File

If multiple objects are selected for export, check this setting to put all generated meshes into a single file. If you leave this option unckecked then a separate file will be created for each selected object.


STL can be saved as a text file or in binary. Check this option to save the smaller binary variant.
