A miniature 3D-printed power loom makes a small piece of cloth by coordinating a series of tightly timed motions: it separates warp threads, shoots a shuttle carrying the weft through the opening, and beats the new thread into place. Fraens’ working prototype shows why automating weaving is harder than simply moving a shuttle back and forth: the shed, shuttle, and beater must act in sequence, and small mechanical changes can make the shuttle miss or snag.
What the Fraens power loom does
Fraens designed a functional miniature flying-shuttle power loom made mostly from 3D-printed parts. Acrylic panels, metal shafts and axles, bearings, springs or elastic elements, gears, sprockets, chain, and a 12V gearmotor complete the mechanism. It is presented as a prototype, rather than an industrial machine. Fraens’ project page describes its parts and downloadable files; Hackaday’s June 7, 2022 coverage explains the mechanism and its development.
The loom’s main functional parts include the heddles, reed, shuttle, beater, warp beam, heald shafts, and cloth beam. In broad terms, it automates the repeated sequence that interlaces lengthwise warp threads with a crosswise weft thread. The maker’s files make the project reproducible as a build, but they do not make it a plug-and-play appliance: assembling and tuning a moving loom still requires mechanical work.
How one weaving cycle works
- Open the shed. Warp threads run lengthwise through the loom. Heddles, also called healds, move selected groups of warp threads up or down, creating an opening called the shed.
- Send the shuttle across. The shuttle carries the weft yarn through that opening. It must cross while the shed is open and clear the loom without catching the warp.
- Beat the weft into the cloth. The beater moves the reed forward, pressing the newly inserted weft pick against the fabric being formed.
- Change the shed and repeat. The heddles shift the warp threads for the next pass, and the cycle starts again. As fabric accumulates, the cloth beam advances and winds it.
These actions are mechanically distinct but cannot happen independently. The shuttle needs a clear path at the right moment; the beater must act after the weft has crossed; and the next shed must form in time for the next pass.

Why automating weaving is difficult
Timing the shed and shuttle
The shuttle can cross only while the warp threads leave its path open. Fraens reports that a simple pulley linkage did not move the heddles consistently. The design instead uses an unusual eccentric profile to lift the warp quickly and keep the shed open longer. Hackaday describes experimentation with cam shapes and lever-arm length to get shuttle timing right, including failed runs during development. As Dan Maloney put it in Hackaday’s June 7, 2022 article, “Dealing with the warp and the weft of it all isn’t easy.”
Delivering enough force to launch the shuttle
The shuttle launcher uses cam-driven levers and stored elastic tension. The project also uses a chain drive to obtain enough torque for the launch. That combination shows why a motor’s rotation alone is not sufficient: the drive must deliver force through the mechanism at the right point in the cycle.

Getting shuttle mass right
Shuttle weight affects whether it travels reliably. Raspberry Pi Official Magazine’s account of the build notes that a shuttle that is too heavy will not move, while one that is too light can snag. The useful mass therefore depends on the launcher and the loom’s geometry; the available coverage does not give a target weight that can be applied to other builds.
Making several motions work together
Opening the shed, launching the shuttle, beating the weft, and advancing the cloth must happen in the correct order, repeatedly. A change to a cam, lever, or shuttle can affect another part of that sequence. That interdependence—not merely the presence of moving parts—is what makes even a miniature automated loom a demanding mechanism to design and tune.

Can you build the Fraens loom?
The project includes downloadable manufacturing and assembly material, so it is intended to be buildable rather than just a concept model. Fraens lists STL files, assembly drawings, a STEP model, base-plate and metal-part drawings, a parts list, and an instruction video. Raspberry Pi’s coverage says STL files were also made available through Printables and Thingiverse and mentions screws, ball bearings, and a 12V motor. Check the project pages for the current file links and exact bill of materials before starting.
Expect a mixed-material build, not an all-plastic print. The design combines printed components with acrylic, metal shafts and axles, bearings, elastic elements, gears, sprockets, chain, and a geared motor. You will also need weaving materials, including warp and weft yarn, and must be prepared to assemble and adjust the mechanism. The published coverage does not establish a current total cost, a required printer specification, or a guaranteed build time.

What the published project does—and does not—establish
The Fraens loom demonstrates a miniature power loom that can weave fabric, and its documented mechanism makes the coordination challenges visible. It is a maker prototype, not evidence of industrial performance. The cited coverage does not publish a measured production rate or establish long-term durability, safety certification, or a current retail price. Those figures should not be inferred from a demonstration or from the existence of downloadable files.
