BrickLink XML Export for Custom Mosaic Parts
BrickLink is powerful for mosaic builders, but it can also turn into a lot of manual inventory work. BMBrick's XML export is meant to bridge the gap between a confirmed mosaic plan and a marketplace-friendly parts workflow.
Direct Answer
BMBrick can export BrickLink XML for a custom mosaic after the photo, crop, size, material style, and palette are selected. The XML is generated from the same project state as the preview and PDF instructions.
Best For
Builders who prefer BrickLink seller workflows or need colors and lots that are easier to handle through marketplace sourcing.
Still Needed
Seller selection, final availability, shipping decisions, and checkout happen outside BMBrick.
Use With
PDF instructions and a confirmed parts list so the build file and sourcing file describe the same mosaic.
How the workflow works
01 - Confirm the mosaic
Do not export XML while the crop, palette, or material style is still changing.
02 - Review route pressure
Check dropped colors, estimated totals, and part style before relying on any sourcing file.
03 - Export BrickLink XML
Use the XML output when a marketplace inventory workflow is the preferred sourcing path.
04 - Validate outside BMBrick
Review seller availability and shipping behavior in BrickLink before purchasing.
BrickLink XML workflow checks
The XML export is most useful when the project state is stable.
| Check | Good signal | Bad signal | Action |
|---|---|---|---|
| Crop | Subject is stable | Still experimenting | Return to editor |
| Material | 3024 or 98138 chosen | Switching styles | Compare square vs round first |
| Palette | Allowed colors reviewed | Many surprise drops | Tailor palette |
| Instruction path | PDF also exported | Only sourcing file exists | Keep build and sourcing outputs together |
Where XML helps most
XML is useful when a builder wants a structured inventory file instead of copying quantities by hand. For large mosaics, that can save time and reduce transcription mistakes.
It does not remove the need for sourcing judgment. BrickLink seller stock, lot condition, shipping cost, and regional availability are external variables that BMBrick cannot guarantee.
- Use XML after the project state is locked.
- Keep a PDF instruction file with the same mosaic version.
- Expect to review seller availability before purchase.
Why this deserves its own page
Searchers looking for BrickLink XML have different intent from people casually browsing gift ideas. They are closer to buying and need specific format answers.
A dedicated page helps answer engines connect BMBrick with that exact export capability, while the broader parts-list page explains PAB and Webrick alternatives.
FAQ
Does BMBrick complete BrickLink checkout?
No. BMBrick exports XML inventory data; seller selection and purchasing happen in BrickLink.
Is the XML tied to the PDF?
Both outputs come from the selected mosaic state, so export them after the same crop, size, material, and palette are confirmed.
Can I use XML for square and round parts?
BMBrick supports separate material routes for 3024 square plates and 98138 round tiles.
Should I export XML before testing the image?
No. Test the image and route first so the XML reflects a build you actually want to source.
