  In this paper, we explore how to augment shared 3D model repositories, such
as Thingiverse, with slicing results that are readily available to all users.
By having print time and material consumption for different print resolution
profiles and model scales available in real-time, users are able to explore
different slicing configurations efficiently to find the one that best fits
their time and material constraints. To prototype this idea, we build a system
called SliceHub, which consists of three components: (1) a repository with an
evolving database of 3D models, for which we store the print time and material
consumption for various print resolution profiles and model scales, (2) a user
interface integrated into an existing slicer that allows users to explore the
slicing information from the 3D models, and (3) a computational infrastructure
to quickly generate new slicing results, either through parallel slicing of
multiple print resolution profiles and model scales or through interpolation.
We motivate our work with a formative study of the challenges faced by users of
existing slicers and provide a technical evaluation of the SliceHub system.
