Parts Export
LEGO Mosaic Parts List Generator
Generate and adjust your photo mosaic in a free preview, then unlock the complete personal parts files when you are ready to build. A useful list matches the selected crop, size, material, palette, and skipped cells. PDF instructions and route-specific exports are paid; physical parts are purchased separately.
Direct Answer
BMBrick generates route-specific mosaic parts files alongside the PDF build plan for 3024 square plates or 98138 round tiles: PAB CSV/JSON when official element IDs are available, Webrick CSV/manual notes for compatible sourcing, BrickLink XML inventory, and a structure BOM CSV.
Preview First
Generate and adjust the photo for free. Complete personal PDF instructions and buying files are paid exports.
Main Risk
A weak crop can create an expensive parts list for background detail that does not improve the finished mosaic.
Best Companion
Use the photo and generator pages first if the project image is still unstable.
How the workflow works
01 - Stabilize the image
Confirm crop and Magic Cut decisions before treating the count as final.
02 - Choose material style
Part style changes color availability, route cost, and surface character.
03 - Select route
Compare supported route estimates before deciding which export file is most useful.
04 - Export and review
Download the route file and verify quantities before sourcing physical parts.
Parts list export comparison
Each export format exists for a different sourcing workflow.
| Route | File type | Best use | Important limitation |
|---|---|---|---|
| LEGO Pick a Brick | CSV and JSON | Official-route planning | Only colors with verified official data can be exported cleanly |
| Webrick | CSV and manual notes | Compatible-route planning | Some colors require manual page ordering notes |
| BrickLink | XML | Marketplace inventory upload | Final seller availability still changes outside BMBrick |
| Structure | BOM CSV | Base/support planning | Depends on the selected mosaic size and structure settings |
Why route-specific lists matter
A single universal parts list sounds convenient, but real sourcing routes do not behave the same way. PAB, Webrick, and BrickLink use different identifiers, availability assumptions, and purchasing workflows.
BMBrick keeps those differences visible so you can check what each file can order. PAB uses official element data, Webrick can require manual notes for colors unsafe for upload, and BrickLink uses its own part and color identifiers.
- Use PAB exports for official-route planning.
- Use Webrick exports when compatible-route sourcing is acceptable.
- Use BrickLink XML when marketplace inventory workflows are the priority.
How to avoid a bloated parts list
The cheapest parts list is usually created before the export step. Tight crop, subject isolation, and a realistic size choice do more to control cost than small post-export edits.
Use Magic Cut and crop review before locking a file. A replacement solid background still uses one part per active cell. Reduce the count only by choosing a smaller grid or actually skipping cells, then confirm the new active total.
Check totals and the separate structure list
For a full 48×48 grid, the pixel inventory totals 2,304 parts. If the plan skips 960 cells, it totals 1,344 instead. The structure BOM covers the underlying base/support configuration separately; review backing, frame, tax, and shipping before treating the order as complete.
Catalog scope: BMBrick's data was verified April 6, 2026 and generated April 15, 2026. Prices are USD planning estimates from that snapshot, not live supplier quotes or stock guarantees. Physical bricks, base/support hardware, display hardware, tax, and shipping are separate from the paid digital blueprint.
FAQ
Can I upload the parts list directly to BrickLink?
BMBrick can export BrickLink XML inventory data, which is designed for BrickLink-style upload workflows.
Does BMBrick buy the bricks for me?
No. BMBrick produces planning and export files. Physical parts are purchased separately through the chosen sourcing route.
Does the list include quantities?
Yes. The exports are based on the selected mosaic and include color and quantity data for the route workflow.
Can I change the image after exporting?
You should treat exports as tied to one confirmed project state. Changing crop, size, material, or palette changes the parts list.
