3D Printing

A few videos back I turned a Noctua A12x25 fan into a siren, it worked but it was only around 70 dB, impressive for a 2000RPM fan but nowhere near real siren sound levels. You all asked me to follow up on that video and make a Tornado siren powered by my miniquad motors, so today that’s what we do

Adding threads to 3D prints does not only improve the look of them but can also improve strength and usability. I’ve been working on a couple of comments and suggestions from the last videos on that topic. We’ll be testing the strength of Böllhoffs Helicoils as well as embedded nut and compare that to the strength of heat-seated inserts. We’ll also take a look at the strength assessment of these connections and see how they compare to our test results!

This is a method I developed a few years back for my day job. We needed watertight containers made from PETG as we were handling chemicals that would easily diffuse through – and break down all other commercially available thermoplastics. After some trials with sand I started using finely ground salt.

It perfectly immobilizes the parts, and gets only superficially embedded. Once the parts are baked, the salt will have superficially embedded itself into the part surface. Washing the part in warm water will dissolve all the salt, leaving behind a sparkly texture.

BIG announcement from Autodesk, in this video I’m conveying the message of what’s going on with Fusion 360 for Personal Use, times are changing, if you use the personal use version then you should be aware of what’s about to happen.
