Demon Slayer 3D Models: Katanas, Masks and Figures

This collection gathers Demon Slayer-inspired 3D models for 3D printing, from collapsing katanas and oni masks to articulated dragons and cosplay props. You can compare how each design is built and what it needs before you commit to a print. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Demon Slayer 3D Models: Katanas, Masks and Figures»

Katanas in this theme often use collapsing or telescoping sections, while masks range from full-face oni designs to smaller display pieces. Articulated dragons and flexi creatures are usually printed as one piece with moving joints, and cosplay items like wings or armor parts may come as multi-part kits. Bookmarks and figurines tend to be smaller, flatter prints that focus on a recognizable silhouette.

Before printing, check the model page for overall size and scale, the number of separate parts, and whether the author lists supports or assembly steps. For articulated or collapsing designs, look at the joint clearances and the recommended material, since brittle filament can affect how the parts move. Photos of real prints and any stated print settings help you judge how the model behaves at your chosen layer height.

If you want more results, try related terms such as oni, hannya, katana, nichirin, or cosplay armor, and combine them with words like articulated or low-poly. Searching for a character name alone may bring up bookmarks and keychains, while adding 'figure' or 'statue' shifts the results toward display pieces. You can also explore broader Japanese folklore or anime-inspired collections to find masks and weapons that share the same visual style.

FAQ

Frequently asked questions

What kinds of Demon Slayer 3D models are available?
You will find collapsing katanas, oni and hannya masks, articulated dragons, cosplay props, and small display figures or bookmarks. The mix changes as new models are added.
Do these models need supports?
It depends on the design. Many masks and katanas are split into parts that print without supports, while some figures and articulated pieces may include overhangs that need them. Check the author's notes for each model.
Can I scale these models for a 3D printer?
Yes, most STL files can be scaled, but you should check wall thickness and joint clearances first. Very small scales can make moving parts fuse together, and very large scales may require splitting the model.
How do I find similar models?
Try searching for related terms like oni mask, katana, articulated dragon, or cosplay armor. Adding '3D print' or 'STL' to your query can narrow the results.
