# How does Carbon3D's CLIP technology handle bridges and support material?

All of Carbon3D's marketing and demonstrations show their CLIP technology producing contiguous and bridge-free parts. Has anyone seen examples of their M1 printing something like a buckyball within a buckyball or a figurine or some other shape that requires support material to print?

For example, how would the Carbon3D print a shape like this:

 vvvvvBUILDPLATEvvvvv
====================
XXX
XXX            BBB <----- columns A and B require support material
XXX    AAA     BBB        in order to connect them to the build
XXX    AAA     BBB        plate.
XXXXXXXXXXXXXXXXXX

In a similar vein, how do they handles enclosed volumes? I doubt anyone wants a sphere filled with still-liquid resin...

Again, I've looked around, I can find no material addressing these questions, so if anyone can shed some light, I'd be glad.

• I believe this could be extended to any DLP/SLA Printer Apr 11 '16 at 20:03
• @Eric Johnson - Well, I understand reasonably well how, say, the Form1 series handle this situation, and I'd imagine that the Carbon3d's M1 handles it in a similar fashion, I was hoping someone might be able to point me towards the M1's implementation—or wven a mention of it—specifically, as the printer operates with very slightly different mechanics than most SLA and DLP models.

• @PostEpoch it might make sense to answer your own question with what you know about how this is handled by the Form1. This might make it clearer which detail of the process is interesting for you. It also would make this knowledge of yours available for others. It might also help answering your question. Jul 12 '16 at 18:41
