Netfabb Standard 2020 includes efficient build preparation capabilities alongside tools for optimizing designs for additive manufacturing, simulating metal additive processes, and planning for CNC post-processing.
What's New in Netfabb 2020
Repairing and remeshing
A new tool repairs gaps between meshes and works best for shapes with organic or smoothly curved surfaces and significant gap widths. Newly generated triangles form a gradual transition between two dissimilar cross sections
Another new repair tool closes holes such that adjacent mesh curvature observed. The hole in the torus to the left has been fixed on the right with a maximum deviation from the original torus surface of only ± 0.7 mm.
A new remeshing algorithm, Manifold Remesh, is aimed at producing valid parts even from meshes with non-closed shells by giving those open shells a thickness and a closed and oriented surface. The flawed mesh (top) has been turned into a closed mesh with a thickness (bottom).
A new support action is available to generate latticed bar support. These scaffolding-like structures provide significant rigidity even in overhangs with undercuts as they can reach into these recesses without sacrificing support strength or requiring part-to-part support.The scaffolding supports otherwise difficult-to-reach surfaces well.
For editing the density map of a part and its support, two new methods are now available in addition to the existing one with a spherical volume of effect: one to affect a cylindrical volume that automatically extends from the supported surface to the respective end on the platform or another part surface, and one where you specify the area by using brush control on the part's surface.
Bar supports created through area-based support action can have their bottom ends split into multiple bars similar to a tree root to provide stronger buildplate attachment.
As downskin analysis can take some based on the complexity of a part, it can now be switched from being performed automatically to be performed on demand by clicking a button.
New machine workspaces include models by Cincinnati Inc. and Solidscape.
The no-build and no-packing zones across Netfabb have been reworked and unified into one common function.
No-build zones look the same everywhere, on regular part platforms and machine workspaces.
Parts can be freely converted from and into no-build zones.
Custom no-build zones (as opposed to those mandated by the build-in machine workspaces) have their own section in the project tree.
No-build zones are observed during toolpath creation in workspaces, when moving parts to Slices, and when running packers.
A new circle-related measurement now measures the distance between arbitrary circle centers directly without projecting the distance onto the plane of the reference circle.
Blueprints can now be created on custom paper sizes.
