Here  we  present  PicPrint,  a  method  and  tool  for  producing  an  additively  manufactured  lithophane,  enabling  transferring  and embedding  2D  information  into  additively  manufactured  3D  objects.  The  method  takes  an  input  image  and  converts  it  to  a corresponding height‐map, indicating  the material density  required  to achieve a  brightness  specified at any given location. Non‐linear  scattering  properties  are  compensated  for  using  predefined  falloff  profiles.  Using  the  produced  height‐map,  a  watertight mesh is  distorted  to match  the  specified material  densities, after which  the mesh is  ready  for either  direct  print  on an additive manufacturing system, or transfer to other geometries via Boolean mesh operations.
