Frequently Asked Questions
Quick answers about conversions, files and supported software.
Is BrickForge free?
Yes. The web converter is free and does not require an account.
What can I convert?
You can convert a single part number, a complete set number or your own MOC parts list.
How should I enter a set number?
Use the complete set number, including the version suffix when available — for example 75344-1.
How long does conversion take?
Small sets usually finish quickly. Sets with hundreds or thousands of parts can take 5–15 minutes, depending on the current queue.
Why can some parts be missing?
Some specialized or newly released parts may not yet have a compatible 3D model. Missing parts are highlighted in red in the Excel file included in the ZIP.
Which slicers are supported?
BrickForge creates multi-plate 3MF projects for Bambu Studio and Orca Slicer. Individual STL files can also be imported into other slicers.
Can I convert my own MOC?
Yes. The MOC tab accepts CSV, BSX, XML, PBG, LDR and IO parts-list formats.
How are parts arranged in 3MF files?
Parts are grouped by filament color. Each plate holds up to 40 parts, each color starts on a new plate, and large projects are split into multiple 3MF files with up to 9 plates each.
What is Parts List Only?
This option creates the set parts list without waiting for STL conversion and 3MF generation.
How long is my completed download available?
A completed ZIP remains available for up to 6 hours, so you can return and download it later while the conversion page is still open.
Are uploaded files stored?
Uploaded files are used only for conversion and temporary files are removed automatically. Generated ZIP archives are automatically deleted after their 6-hour availability period.
What is BrickForge Desktop?
The desktop application is an optional separate tool for people who already have their own local STL library and want to organize files and build parts lists and 3MF projects on their computer.
