# How to generate a file for resin printing from layer by layer images?

(Asked by: username_0 on 2022-11-30)

I would like to print an object on an Elegoo Mars 3, object which is generated layer by layer via other means.

So as input I have a series of BMP or PNG black and white images, one for layer, and I need to somehow assemble them to obtain a CTB printable file.

The solution can either involve generating a 3D model to be loaded in Chitubox, or it can involve generating directly a CTB file.

How can do that?
