Viscosity Has Been Conquered, ViscoTec Enables Precise Printing – Video The more viscous a material is, the harder it is for a 3D printer to use it. Or, extruders melt plastic well e**ugh, but liquids deform when placed on a flat surface, and materials forced through Printing heads are unfortunately subject to this issue.
This is why ** 3D printed object ever turns out perfect, when made with Fused Deposition Modeling (FDM).
**w, though, ViscoTec claims to have found a solution for this problem, or at least a way to alleviate it.
