3D Printed — Um — Hook And Loop Fasteners

September 4, 2023 by 38 Comments

[Teaching Tech’s] latest video discusses “3D printed Velcro.” But as even he admits, Velcro is a trademark, so we think it is more appropriate to talk about hook and loop fasteners. In fact, you can see the good-natured official video about the trademark below [Teaching Tech’s] video. Regardless, his experiments with several 3D-printed Vel… fastener designs are worth watching.

Some of the designs were rather large, like we would have expected. However, some of the designs were fairly small and looked almost like real Velcro. However, since the pattern is not as random as the fabric portions of the real deal, it seems like alignment between parts is more critical when you are joining the two halves.

Mechanisms: Hook And Loop Fasteners

April 19, 2018 by 35 Comments

As a species, we’ve done a pretty good job at inventing some useful devices. But as clever as we think we are, given sufficient time, natural selection will beat us at our game at almost every turn. So it makes sense that many of our best inventions are inspired by nature and the myriad ways life finds to get DNA from one generation to the next.

Hook and loop fasteners are one such design cribbed from nature, and the story behind this useful mechanism is a perfect example that a prepared mind, good observation skills, and a heck of a lot of perseverance are what it takes to bring one of Mother Nature’s designs to market.

Editor’s Note: As some predicted in the comments section, we were contacted by representatives of Velcro Companies and asked to change all mentions in this article to either VELCRO® Brand Fastener or to use the generic “Hook and Loop” term. If it seems weird that we’re calling this hook and loop, now you know why.

3D Printed Velcro

Velcro

With new materials comes new possibilities in fabrication, and with 3D printers, this observation is no different. In the past year or so, there have been a few very interesting new filaments that have come into mainstream use – a printable sandstone, high impact polystyrene, and a flexible PLA. When [Rich] saw a bike light that had an integrated hook-and-loop fastener – think Velcro – built in to its enclosure, he thought to himself, ‘I could do that too.’

[Rich]’s “ElastoStraps” are printed with Makergeek’s Flexible PLA, and the entire device works surprisingly similar to other hook and loop fasteners with a registered trademark. The design is up on Thingiverse, and since the object was designed with OpenSCAD, the 3D printed Velcro can also be opened up in the Customizer for hook-and-loop straps that perfectly suit your needs.
