Atlantis 3D model

Atlantis (Ancient Greek: Ἀτλαντὶς νῆσος, “island of Atlas”) is a fictional island mentioned within an allegory on the hubris of nations in Plato’s works Timaeus and Critias, where it represents the antagonist naval power that besieges “Ancient Athens”, the pseudo-historic embodiment of Plato’s ideal state.In the story, Athens repels the Atlantean attack unlike any other nation of the (western) known world, supposedly giving testament to the superiority of Plato’s concept of a state. The story concludes with Atlantis falling out of favor with the deities and submerging into the Atlantic Ocean.(By Wikipedia)

Today, we are going to show you how we have recreated this amazing model of mysterious Atlantis island with the Stereolithography (SLA) 3D printing technology. The process is quite simple, which includes model creation, 3D printing, and finally post-processing.

1. 3D Model Creation

create your model 3D modelling software and export as .STL file

2. SLA Printing

We evaluated the model from different perspectives including structure, size and printing time and decide to use SLA to manufacture this model.

SLA(Stereolithography) uses UV light of certain wavelength to solidify the liquid resin sitting in the material tank. The UV light will be able to solidify layer by layer when the model sitting on the base gradually moves up.

how SLA works when printing

We have separated the model into seven modules, with one major city and six surrounding cities, so that each model can be printed with our machine which has a size limit on model.

3. Post-processing

There are a couple of steps involved in post-processing.

I. Support Removel

After printing, we need to remove support from the model. The fresh model need to be washed by alcohol, which is able to soften the support and wash away resin residuals on the model.

II. Solidification

After removing the support, the model are sent to solidification box to improve the stability and strength of the model.

III. Paint

We applied three layers of paint to the model in this case.

  • The black paint as base  The black paint can protect the model from the sunlight as the photo-reactive resin will react to lights and gradually turn yellow over time. The black paint will prevent this phenomenon.
  • The major color paint We decided to use the chrome paint here to give the model a metallic surface finish.
  • The finish layer of clear polish paint to protect the major color layer.
