I've received Discov3ry last month and having fun time optimizing and getting used to it.
I'm using Discov3ry with Seemecnc Orion delta and trying to test print few materials by researching their viscosity and their printability.
But I've found that a viscosity of a material changes with applied shear strains due to thixotropic behavior. So I noticed that the shear rate of Discov3ry's syringe tips must be studied as well in order to find out clear relationships between viscosity and printability.
Would anyone studied about the shear rate when paste materials are being extruded through "cone-shaped" syringe tips as the ones provided with Discov3ry?
This would be very good starting point to match up viscosity and paste printability of the materials and give basic idea to people when they want to 3d print pastes with Discov3ry.
