I have a DEM raster layer created from contour lines in Qgis 3.0 using v.to.rast to get my contour raster and then r.surf.contour to get the DEM.
The trouble is, somewhere in the process, the cell size for the resulting raster layer is too big and the 3D map is 'terraced'.
How do I reduce the cell size (make the resolution higher)?

You could use the GRASS tool r.resamp.interp which allows you to resample your raster to a finer resolution by specifying the cell size.
