This series of posts is just the latest of many reasons why I heart the I Heart Engineering team’s I Heart Robotics (the internet blog). It consists of 3 posts, so far, each of which examines the use of a particular type of threaded fastener in fused-filament plastic parts like those produced by most desktop 3D printers. So far, they’ve hit common wood screws, special self-tapping plastic screws, and machine screws paired with these cool melt-in threaded inserts you can get (along with a special soldering iron tip for installing and removing them) from McMaster-Carr. The posts include downloadable data and specific recommendations for each type of fastener. If you build stuff with fused-filament parts, don’t miss it, and keep an eye peeled for the next installment. [via adafruit]

  1. [...] Earlier this month, we linked out to the first three posts in the I Heart Robotics team’s ongoing series about choosing hardware for the fused-filament parts that come off your RepRap-type 3D printer. On Sunday, they published the fourth installment, this time focusing on the best way to make a rotating pin joint between two printed beams, for instance in the “knee” of a robot leg. They experiment with various configurations of pop rivets, tubular rivets, flat washers, spring washers, clevis pins, and E-rings. Click through, below, to check out their results. [...]
