I understand that if the bases of internal supports are too small, they are susceptible to breaking off. But right now, these bases leave a very noticeable blemish when they are removed. It would be nice to be able to customize the internal supports more.
I would also like to be able to use smaller support contacts than is currently available. I’m sure Formlabs has done a significant amount of testing, but I still can’t help but wonder if smaller supports are possible. I have yet to have any of my prints fail due to support issues and I always use the smallest contact points. It would also be nice if the slop of the tips could be adjusted. Right now, when 2 or 3 support tips are near one another, they can affect the detail of the part and be difficult to remove.
I have some experience with Materialise Magics. The Support Generation module for Magics makes some very different types of support structures. It may be beneficial to have the option to produce these as well. Examples from the various softwares can be seen here: http://software.materialise.com/build-preparation
I have often wondered if it would be possible to produce internal supports whose bases do not contact the part but could snake through the part from the outside to provide internal support. This idea is inspired by the Materialise Metal Sintering module.
