Multiboard Printing Guidelines

Default Printer Settings

Use 3 perimeter wall thickness, 0.2 mm layer height, 15% infill, and no supports. Apart from that, use your printer's default settings.

The printing orientation is as provided in the files. Make sure the downloaded files are .STL.

Most parts are designed with a tolerance of 0.25 mm and to be as close to 45 degrees as possible (sometimes 50 and 60 degrees).

Nozzle Size: 0.4 mm.

Material: Matte PLA (Matte PLA is stronger than regular PLA).

PS - Some parts have different printing settings, make sure to check the description of each part before printing.

Stack Printing

Ironing Stack Printing (Recommended)

Stack Prints are parts that are printed on top of each other. “Ironing” Stack Prints have a 0.2 mm gap between each print and use ironing to prevent sticking.

When stack printing, one side of the tiles aren’t going to come out as nice as printing individually (in case you want to use them double-sided).

Printer Settings: Turn on "ironing" for top surfaces. Set seam position to "random" for more strength (optional). Use 3 perimeter wall thickness, 0.2 mm layer height, 15% infill, and not supports. Apart from that, use your printer's default settings.

If Ironing Stack Printing doesn't work for you, then try out Multi-Material Stack Printing 👇.

Multi-Material Stack Printing

What Is Multi-Material Stack Printing?

Multi-Material Stack Printing is an advanced printing method you can use if Ironing Printing doesn't work for you, and you have a multi-material printer. Multi-Material Stack Printing printing is done with PLA and PETG.

We don't suggest doing manual pause printing if you don’t have a Multi-Material printer.

Multi-Material vs Ironing Stack Printing

Pros of Multi-Material:

  • Leaves a cleaner finish on the bottom side of the Tiles than Ironing printing.

  • Easier to take Tiles apart.

Cons of Multi-Material:

  • It's usually slower.

  • Requires a multi-material printer.

  • Requires PLA and PETG.

  • Testing is required to find the right printing settings.

Multi-Material Printer Settings:

  • Make sure the downloaded files are .STL. The printing orientation is as provided in the file.

  • Once the file is in the slicer, split it by objects. Change the Tiles to be PLA, and change the spacing objects to be PETG (or vice-versa).

  • Change the plate temperature for the PETG to be the same as the plate temperature for the PLA.

  • Set the flow ratio (aka extrusion multiplier) for the PETG to be between 1 and 1.3. You will have to test what flow ratio works best for you using this test file. For me 1.1 works best with a Bambu Lab.

  • Set seam position to "random" for more strength (optional). Use 3 perimeter wall thickness, 0.2 mm layer height, 15% infill, and no supports. Apart from that, use your printer's default settings.

Material Shrinkage

During printing, high-temperature extruded plastic undergoes volume shrinkage due to cooling.

This can have an effect on tall Multiboard parts, particularly Multibins that are taller than 2 cells high (100 mm). To solve this, you can scale your 3D models on the z-axes.

Now, material shrinkage can change depending on the material, brand, color, humidity, and temperature; so you can’t get it right 100% of the time. But you can get a pretty good approximation by checking the “shrinkage percentage” of your material by clicking here (It’s better to go a little bigger rather than small).

Then in your slicer, hit “scale” on the z-axis and increase the height by that percentage. I personally scale PLA Multibins by 100.5%
