This is a good question. Monolith has the ability to export meshes and bitmap slices. The meshes can be read in my most printing software and printed that way. The bitmap slices were a test to print directly from bitmap images... which gives you greater control over the microscopic patterns and printing hairline features. For this, we were working with the Stratasys Objet series of printers... however, you needed a special hardware dongle which would give you access to their print software that enables bitmap printing. Unfortunately, these dongles are very difficult to get a hold of and have generally been reserved for academic institutions (although you'd have to talk to Stratasys specifically about this). Anyway, right now mesh output is probably the most generic... however, we're working on other output formats to get around this limitation for the next release.
