Apparent dip is the inclination of geologic beds as seen from any vertical plane not perpendicular to the strike of the geologic beds. This block model shows an inclined marker bed appears on five different vertical faces that are not perpendicular to the strike of the marker bed.

These models would typically require the use of a dual-extrusion printer and can be printed in a variety of materials. PLA has been our choice and has worked well for us. The dual-extruder printer files folder contains two .stl files. The marker bed and body files can be merged in the printing software and get assigned different colors. 

It is of course also possible to print the pieces individually and glue them together as well! The second folder, named “single-extruder printer files”, contains each of the pieces that can be printed separately.
