Fiberglass Mesh For Stronger 3D Prints

There are many clever ways to make stronger 3D prints, be they by the use of special slicing algorithms or by unusual filaments. [Brtv-z] has taken a more straightforward tack, by making glass-reinforced prints using painters fiberglass mesh tape.

It’s a laborious technique that involves stopping the print to manually place the fiberglass at each successive millimeter of print. The resulting test piece comes off the print bed festooned with fiberglass mesh, and once it’s been trimmed, he subjects it to some tests which you’ll see in the video below the break(Russian language, but there are subtitles).

The tests are fairly rough and ready involving a hammer (we winced at the hammering in a vice, but of course this piece isn’t forged steel!) and standing on a flat piece of print balanced between two blocks. As you’d expect, the reinforced piece appears the stronger, but these tests would benefit from a calibrated set-up to quantify the strength.

So if you’re of a mind to experiment, this certainly seems like an accessible if rather tedious way to make glass reinforced 3D prints. If you then want to characterize them, remember this can be done with a bit of farmyard engineering if you have nothing better.
