100 % mechanical
11-plate nonstop runs
For makers who love to tinker
PrintFlow3D DIY Kit
The PrintFlow3D DIY Kit includes all non-printed components required to build your own mechanical plate changer for the Bambu Lab A1. The system is 100% mechanical – no electronics, sensors, or firmware modifications are needed. Designed for makers who want full control and a hands-on build experience, the DIY Kit allows automated multi-job printing with up to 11 plates.
The kit contains seven pre-manufactured parts, including the magnetic plate base, Bowden cable, and mounting elements, as well as a complete hardware set with screws, springs, neodymium magnets, dowel pins, and heat-set inserts. All necessary STL files for 3D printing are provided, along with the PrintFlow setup tool for STL modification and plate change integration. A detailed assembly guide is available in both PDF and video format.
To complete the build, you will need:
All DIY Kits support up to 11 print plates.
The only difference between variants is how many plates can be equipped right away.
Each higher kit includes additional mounting hardware for more plates – no need to source parts later.
Includes STL file to modify your own Bambu Lab plates – no drilling needed. Just print, clamp, and go.

The PlateChanger uses a fully mechanical swapping process triggered by the print file itself. After a print finishes, a mechanical motion pushes the finished plate out and automatically loads a fresh one into place—no electronics, sensors, or motors involved. You prepare your print job using the PrintFlow3D Setup Tool. It inserts the required movement directly into your STL file, which can then be sliced as usual in Bambu Studio. This process enables up to 11 prints in a row, completely unattended—perfect for overnight jobs or continuous production.
The DIY Kit comes with everything you need to build the PrintFlow3D PlateChanger – except the 3D-printed parts themselves. Included in the box are seven pre-manufactured components such as the magnetic base, Bowden system, and mounting elements, along with a complete hardware kit containing all required screws, brass inserts, magnets, springs, and dowel pins. You’ll also receive STL files for all printable parts, our dedicated setup tool for print job integration, and a step-by-step assembly guide in PDF and video format. To complete the build, you’ll need a few standard tools (not included in the kit): a soldering iron (for brass inserts), hex keys, a small hammer or press tool, and an adhesive suitable for PETG, such as UHU Allplast or two-part epoxy.
The PlateChanger is exclusively compatible with the Bambu Lab A1. It does not work with the A1 Mini, P1, or X1 series. The system is mechanically tailored to the A1’s dimensions and motion system for precise and reliable performance.
The PlateChanger is a fully mechanical system—it requires no power, no sensors, and no firmware changes. All motion is controlled via custom print paths embedded in the STL using the PrintFlow3D Setup Tool. Compatible with official PrintFlow3D plates or your own modified Bambu Lab plates. Each kit includes the STL file and mounting hardware to retrofit up to 11 standard Bambu plates – no drilling required. Max. capacity: up to 11 plates Plate size: 256 × 256 mm Plate surface: PEI-coated spring steel
