Dan Topjian's Kevlar® Reinforced Envelope Opener

thingiverse

We’ve been talking about inserts a lot this week at MarkForged. The ability to add embedded hardware is one of the aspects of additive manufacturing that strongly differentiates it from traditional manufacturing methods. You can add magnets, RFID chips, hardware controllers or many other types of embedded hardware. A part Dan likes to use to demonstrate this ability during MarkForged training is a Kevlar® reinforced letter opener. This is a great demonstration part because it only takes about 4 hours to print and only uses about 5 cubic centimeters of nylon and 5.7 cubic centimeters of Kevlar®.
