3D Printed Halloween Pumpkin Lithophane

By ItsLitho

In this guide, we will explain how to create a 3D printed Halloween lithophane perfect for scaring your neighbors! With ItsLitho it’s easy to create this Pumpkin shaped lithophane.

Usually Thingiverse has some pumpkin shapes with a face in it. But what if you would like to have a witch or ghosts on a pumpkin? Without ItsLitho you would have to manually model this, which takes a lot of practice and most importantly a lot of your time!

So how do you create a good looking 3D printed pumpkin lithophane? Of course by utilizing the ItsLitho lithophane maker! In the shape select box choose the pumpkin shape. The pumpkin lithophane has many options but don’t be afraid, many of these options are just to fine-tune your pumpkin lithophane. The default settings are already great for printing. However, you can modify every aspect of the pumpkin shape which need some explanation. In this guide we will walk trough the these settings!

Step by step Halloween lithophane​

Halloween pumpkin lithophane

A pumpkin lithophane requires some extra attention printing. There are parts where the overhang angle is too large for your printer to handle well. The pumpkin lithophane is therefore somewhat harder to print than your typical lithophane.
Creating the Halloween lithophane will be explained by creating the pumpkin from the image above. This pumpkin lithophane was also printed and can be seen at the end of this step by step guide.

Step 1: Create your Halloween lithophane

For now, the image is stretched over the entire pumpkin. This is often undesired. To counteract, do the following:

Step 2: Slice and support your Halloween lithophane in the slicer

The 3D printed pumpkin lithophane requires some extra attention. There are most likely large overhangs on the top and bottom of the pumpkin.

The top of the pumpkin will most-likely be suspended from the ground and not connected to the other parts of the pumpkin as shown in the image below.

It is important to give this some thought. We suggest you use supports to be able to print the pumpkin lithophane. The best way would be to manually add supports for the top and bottom of the lithophane.

But a quick and easy way is to turn on the supports in your slicer. Increase the support overhang angle threshold to a high angle, such as 70 degrees. This will make sure that only the absolute necessary parts will get support and often will avoid putting supports on the lithophane itself.

Step 3 Impress your neighbors

In the last step, you’ll simply have to print the pumpkin lithophane. Choose a suitable filament such as orange PLA or white PLA with an orange/warm white light.

Our recommendation for this print is the Orange PLA from Geeetech which we used ourselves. If you choose to print it with white filament, we recommend Esun Cool White PLA, which is in general one of the best filaments for the use of lithophanes!

After this send the STL to your printer and wait to see the pumpkin slowly appear on your print bed! Make sure to carefully remove the supports from your pumpkin lithophane.

It’s that simple! The new ItsLitho pumpkin lithophane is the answer to your Halloween success story. Would you like to share your pumpkin lithophane or see what others have made, then please join our Facebook group!

Customize your pumpkin lithophane options

For those who likes a lot of options, we provide a lot of adjustable settings for this pumpkin shape on ItsLitho. These options will give you full control over the pumpkin shape. We will explain these options below.

Most important settings

We’ll first briefly explain the settings which will make up your pumpkin lithophane. The cad drawings below will help you understand what each parameter means.

Quick end note

We came up with the idea of how to do a Halloween lithophane 2 weeks prior to Halloween. We have developed this function in record time so that our users still have time to print it before Halloween. As a result, there are still bugs in the pumpkin lithophane. Known bugs:

  • Multiple images do not work if the texture option is turned off;
  • Attributes do not work well (it might sometimes) with the pumpkin lithophane;
  • Grooves increases by the number of images uploaded
  • Images are stretched over the entire pumpkin, in the future, we will add an automatic position function to retain the image aspect ratio!

Our first Halloween lithophane test is an undeniable success. Not only is this our first 3D printing lithophane pumpkin test print, it also acts as our proof of concept. With this proof of concept, we’ve shown that a pumpkin lithophane works great! Our family and neighbors were very impressed and yours will definitely be too! We can’t wait to see what you can come up with!
