Summary

  • Designed a 3D printed lithophane lamp in Soldworks.
  • Main feature: Replaceable lithophanes of chosen standard of aspect ratio/dimension.

Features

  • Top/Bottom Panels retained with three M3 screws – Removing the panels gives access to replacing the printed lithophane.
  • Wiring threads through back of assembly and socket leans on back the back panel.
  • Forward attachment clamps the socket and constrains the forward movement of the light socket with screws.
  • I have two slightly different designs to accommodate either an E14 lamp socket or an E27 lamp socket.
  • This was due to supply issues of light sockets at the time of design which prompted a redesign due to time constraints.

Printing and Design

  • Images are preprocessed to correct specs and lithophane stl’s are generated using: https://itslitho.com"
  • Lithophane thickness parameters:
    • smallest wall thickness 0.9mm
    • largest wall thickness is 3mm
    • border thickness: 5.25mm
  • Printed on Creality Ender 3 pro:
    • 0.4mm nozzle
    • Total print time is 26 hours (my printer set-up)

Animation

  • The version shown below in the pictures is the E14 litho lamp:
    • Max Width = 185mm
    • Height = 130mm
