A jack-o'-lantern is a classic Halloween decoration, but why settle for the usual carved pumpkins when you can 3D print intricately designed, customizable faces? With a 3D printer, you can create a wide variety of spooky pumpkin faces that are far more detailed than hand-carved versions.


You can easily swap out different faces or add animated elements like glowing eyes or even light-up features. By combining 3D printing with LED lights or glow-in-the-dark filament, you can create an eerie glow that makes your jack-o'-lanterns look truly terrifying in the dark.


Printing Tips:

  • Use glow-in-the-dark filament for an extra spooky effect.

  • Opt for high-detail settings to bring out the intricate details in the face designs.

  • Print multiple sizes to create a whole family of jack-o'-lanterns!

Add an eerie entrance to your home with a 3D-printed haunted door knocker. This project is perfect for setting the tone right at your front door. From skeletal hands to ghostly faces, a spooky door knocker will leave no doubt that Halloween has arrived at your home.


The designs can range from classic skulls to more intricate, animated knockers that move when someone approaches. Plus, it can be combined with sound modules to create an unsettling sound whenever the door knocker is used.


Printing Tips:

  • Ensure the knocker has enough thickness and weight to create a realistic knocking sound.

  • Experiment with metallic or stone-like filament to give your knocker a more authentic look.

Nothing screams Halloween like a bony skeleton hand reaching out from the walls. With 3D printing, you can create life-sized, detailed skeleton hands that look like they’re emerging from the wall. These can be mounted anywhere in your home to add a subtle but unsettling Halloween atmosphere.


Not only do skeleton hands make for great standalone decorations, but they can also be functional, acting as hooks for hanging bags, keys, or even Halloween candy. You can scale the design to different sizes for a personalized look.


Printing Tips:

  • Choose a matte white or bone-colored filament for a more authentic skeletal appearance.

  • For an extra creepy effect, use resin printing for super high-detail bones.

No Halloween is complete without candy, and what better way to serve it than in a 3D-printed witch’s cauldron? This project can be scaled up or down depending on your needs, creating anything from a small tabletop bowl to a larger centerpiece for your party.


A cauldron bowl adds a magical, spooky vibe to any Halloween spread. You can also add smoke effects or LED lights to make it glow, mimicking a bubbling cauldron. Plus, you can design the cauldron with intricate symbols or patterns to make it look like it's straight out of a witch's lair.


Printing Tips:

  • Consider using black PLA filament for a traditional cauldron look.

  • Reinforce the base with a thicker layer to ensure it can hold plenty of candy.

Printing Tips:

Take your Halloween costume to the next level with a fully 3D-printed mask. Whether you want to be a creepy clown, a skull-faced ghoul, or even a famous horror movie character, 3D printing lets you customize your mask to fit your exact vision.

Printing Tips:

  • Use flexible filament like TPU for more comfort around the edges of the mask.

  • Consider using a resin printer for fine details, especially for facial features.
