Non Planar Printing
Home > Software > Non Planar Printing
What we usually call '3D Printing' is actually 2.5D, flat 2 Dimensional layers are built up into a 3 Dimensional object. Non-planar printing aims to achieve true 3D printing, where the print head moves in 3 Dimensions, which can lead to a much higher quality surface finish where there are more curves, eliminating a staircase-like appearance. This page provides some links to research and resources regarding non-planar 3D printing.
| Warning: Non planar printing is currently in a highly experimental state, and if parameters are not correctly configured it is possible you could seriously damage your machine. Proceed with caution if putting into practice any of the resources listed below! |
