Make a Dungeon Diorama with foam - and 3d printed miniatures

In this tutorial I show you how to easily make a good looking dungeon diorama. This is also very suitable for table top gaming.

You just need a few supplies. And I use 3d printed miniatures as the various furnishings in the diorama.

I also have a video tutorial on this project. I show you how to make this diorama. That video is at the bottom of the page.


3D printed parts have come a long way in the past several years. And now you can easily get all kinds of great looking miniatures custom printed for use in table top gaming and other things like dioramas.

This picture shows the completed dungeon. I have taken the picture in low light so you can see that the cauldron is lit up with an LED.

The dungeon

A couple of things to note here and I will show you all these techniques . First off the floor of the dungeon is divided into squares which makes it very suitable for table top gaming. Secondly the walls of the diorama have a great stucco texture. I will show you how to do this and how to paint it so it comes out great.

This picture shows a closeup of the textured and painted wall.

Also, all the miniatures in this diorama are 3d printed. I will take a closer look at these in the second part of this tutorial. Finally, I will show you how I modified and wired up the cauldron so it lights up.

The glowing cauldron


Here are the miniature printed parts I received for this project. They are from Hobgoblin3D. Perfect for a dungeon diorama or for tabletop gaming in the 28mm scale. In part 2 of this tutorial will take a closer look at them, paint them, modify them, and show you the easy process for getting 3d printed parts without having a 3d printer.
