recycled resins: sometimes they’re just better

mechanical engineering

The biggest hurdle to overcome with regards to using resin containing recycled content is something I like to call the performance bias. Our performance bias tells us that in most cases, second hand materials aren’t going to perform as well as their brand new counterparts. It’s a bias that generally serves us well, but during [...]

When I first heard the term “side action”, I got what it was… but couldn’t quite envision how the tool worked. I was told that: A side action is something that allows you to create a feature with a pull direction that is at an angle to the primary pull direction. In hindsight that seems [...]

Designing with polyurethane memory foam (a.k.a viscoelastic foam, a.k.a tempurpedic foam) is different. It’s not as conventional or dimensionally stable as plastics or metals, but when it comes to comfort, it can’t be beat. So how do you do it? How much does it cost?
