Accurate topology for Solar Park Planning with 3D Printing

Brief Overview

3D Printing can be used to create miniature scale models of mega structures & topologies. APSPCL (Andhra Pradesh Solar Power Corporation Limited) wanted an accurate model of the installation site to help in operations and in easy demonstration of the location to key stakeholders. A digital topology is created using coordinates and is 3D printed at 1:4250 scale.

Client Background

Andhra Pradesh Solar Power Corporation Pvt Ltd (APSPCL) is a Joint venture between SECI (Solar Energy Corporation of India), APGENCO (Andhra Pradesh Power Generation Corporation Limited) and NREDCAP (New & Renewable Energy Development Corporation of Andhra Pradesh Ltd.) It has been formed for development of Solar Park in the newly formed state of Andhra Pradesh.

The Project

APSPCL has taken up the task of setting up 1500 MW solar park at NP Kunta mandal, Ananthapram District of Andhra Pradesh in two phases. The MD. Of APSPCL wanted an accurate model of the site with 1:4250 scale, which will help in planning the operations and demonstrating it to the key stake holders accurately. During the execution of the project their team came up with a few indigenous solutions to cut down the time and cost of setup. He wanted to showcase these with the help of the 3D model.

Solution & Execution

  • think3D team collected the coordinates from the APSPCL team, and came up with accurate 3D topology in STL format
  • The 3D contours were then divided into multiple blocks and printed separately using FDM 3D printers.
  • With inputs from APSPCL team, detailed features like cable racks, towers, canals and panels were developed to the scale.
  • With the help of an in house artisan team all the blocks were assembled, treated with colors as per satellite images and onsite pictures. The developed features were assembled, and all features were labeled.


At the end of this entire exercise, a highly accurate and detailed scale model was developed, which was installed on site at the field project office. The model proved to be a great tool for APSPCL team for accurate execution of plans and effective communication to stake holders and vendors.
