Sacrificial Bridge Avoids 3D Printed Supports
[Tommy] shares a simple 3D printing design tip that will be self-evident to some, but a bit of a revelation to others: the concept of a sacrificial bridge to avoid awkward support structures. In the picture shown, the black 3D print has small bridges and each bridge has a hole. The purpose of these bits is to hold a hex nut captive in the area under the bridge; a bolt goes in through the round hole in the top.
Readers familiar with 3D printing will see right away that printing the bridges might be a problem. When a printer gets …read more
