I did a Durable print today where I only needed a few touchpoints toward the top of my part. Here’s the lattice Preform generated:
That tall, skinny truss isn’t nearly robust enough. Here’s how it turned out on my Form 3:
I printed a few of these, here are some others:
I’m surprised just how wobbly the lattice got! (I’m tempted to try it on my Form 2 for comparison).
It’s been requested before, but here’s a great example of where it would be nice if some advanced feature let you edit touchpoints on both ends of the supports. There’s no need for the bottom of those supports to touch my model at all - the truss could widen slightly toward the base and straddle my model to make contact with the raft instead. And if their bottom ends don’t touch my model, I’d be happy to see Preform throw in a few more truss columns and bracing to make the lattice more rigid.
I’m going to craft a custom support lattice for my next attempt, but thought I’d share this in case it’s of value for the Preform developers. (If anyone thinks the fault is my printer, let me know and I’d be happy to run other tests).
