3D Printed Braiding Machine / How It Works, Construction, Technical Details

In this video I build a 3D printed braiding machine. The braiding machine was recreated from old photos, from the early days of braiding machines. The braiding machine works really great. So far I have created about 50m of cord without any problems. The output is 42cm per minute. A 24V DC gear motor drives the machine. 6 bobbin holders are used. A bit tricky was the device for tensioning the single cords. But this works perfectly now. If you change the gear ratio, it is also possible to produce cords with a core. All parts are easy to print. Supports are included in the 3D models. On Thingiverse and Prusarprinters I have made all parts, drawings and templates available for download. Have fun building.

Step 1:

Here you can see the basic assemblies.

Step 2:

The base plate was made of acrylic glass. The shape was printed on paper and glued. The parts are cut, sanded and drilled.

Step 3:

3D print the parts. All parts can be downloaded.

Step 4:

Here you can see the base plate with the gears. 6001-2RS ball bearings are used.

Step 5:

The shuttle is guided in the acrylic guide. The gears push the boat further and further.

Step 6:

This is the coil holder. A 12x1mm aluminum tube was used. The steel weights ensure the maintenance of tension in the cord. The spool holders circle each other, braiding the line.
