Designing models for 3d printing
Designing models for 3d printing - sh.itjust.works
I came across a really clever idea today for minimizing warping on a large flat surface. The modeller made the first two layers into a series of bridges, which seems to let the plastic shrink and stretch a bit, also preventing some possible blobbing. At least I assume that’s what’s going on here. I’ve never seen it before, but it printed great without curling or warping. I’ve also picked up some looser ideas. Things like: - Adding a 0.02 tolerance to interlocking part will help parts fit together. Adding small chamfers to edges will also help - 3 shells helps give a nice, smooth surface - Orienting parts on the bed so that layers are perpendicular to stress can prevents layers from delaminating in functional parts - Orienting parts such that fine details are vertical will help things look prettier - Add slight chamfers on the underside of overhangs can help minimize or even eliminate the need for supports - Create inset holes with this method [https://hackaday.com/2020/05/17/look-ma-no-support-for-my-floating-holes/] to eliminate the need for supports. This also works with other shapes [https://youtu.be/KBuWcT8XkhA] What other modelling tricks have you seen?
