About Project

5G will allow for smart traffic lights, which connect with cars on the road to improve traffic flow and make the roads safer. Here are the models we 3D printed for a 5G traffic intersection safety project, including solar street lamp, road signs, etc.


  • Step 1: The client split the model into different parts with Solidworks, and export the STL file for printing. Our engineer would help her examine the model.
  • Step 2: We arrange the parts in software and add necessary supports. Then 3D print them with SLA Generic Resin. The layer thickness we set is 0.05mm and we control the tolerance within ±0.2 mm.
  • Step 3: When printing is completed, rinse the models with IPA and post-cure them with UV. Cut off all the supports, then polish with sandpaper.
  • Step 4: Paint with airbrushes and screen-print the marks. Glue the parts together.
