Turning a piece of derivative work (fan art) into a 3D model touches on the reproduction right and the adaptation right held by the rights holder of the original work, so it is, as a rule, an area that requires permission. In practice, you start by checking how the target work's fan content guidelines treat three-dimensional works and data distribution. There are two reasons why you have more to check than when you publish a flat illustration. First, many rights holders treat three-dimensional works separately from flat fan art. Second, because a 3D model is "data," it adds issues that flat illustrations never had: publishing, distributing, and sending files to outside service providers. This article focuses specifically on turning fan art into 3D models and lays out the order in which to check things.
This article is a general overview of information and is not legal advice. Nor does it declare that any particular work is "definitely fine." Where a judgment call is needed, please check the rights holder's guidelines and, if necessary, consider consulting a lawyer or other specialist.

Note: Figmee currently lets you generate and download figurine-style images and 3D model data (GLB / 3MF) from drawings and illustrations you upload. Sales of physical 3D-printed items are in preparation (Coming Soon). Figmee is designed for turning characters and original illustrations that you own the rights to into 3D.
The basics: two rights involved in making something 3D
Let's start with the fundamentals. Under Japan's Copyright Act, the reproduction right (Article 21) states that "the author has the exclusive right to reproduce their work," and the adaptation right (Article 27) states that "the author has the exclusive right to translate, arrange musically, transform, dramatize, cinematize, or otherwise adapt their work" (you can check the text in the Copyright Act on e-Gov Law Search, as of July 2026).
Recreating a flat illustration in three dimensions can involve this kind of "reproduction" or "transformation/adaptation." And in the case of fan art, the person who holds these rights is the rights holder of the original work. In other words, it is as a rule an area that requires the rights holder's permission.
In reality, however, many rights holders publish fan content guidelines that explicitly allow a certain range of activity. So the practical starting point is not "Is this illegal?" but reading how the target work's guidelines treat three-dimensional works.
Guidelines often treat 3D works separately
This is the single most important point when turning fan art into 3D. When you open a set of guidelines, flat illustrations and three-dimensional works are not necessarily described under the same conditions.
As a real example, the fan content guidelines Capcom published in November 2025 list three-dimensional works among the types of works covered, alongside illustrations, manga, games, and novels. On top of that, they set the condition that paid sales of figures and garage kits are permitted only at events such as Wonder Festival, for which the company grants same-day licenses. They also state that while use for commercial purposes is not permitted, small quantities at small prices within the scope of a hobby, such as at doujinshi conventions, are allowed as an exception (sources: Capcom Fan Content Guidelines (official); for press coverage, 4Gamer.net (November 5, 2025); both as of July 2026).
In other words, even for the same work, drawing it as an illustration and selling it as a three-dimensional piece come with different stated conditions. If you miss this difference and go ahead because "it said fan art is OK," the result may be treated differently than you expected.
As another example, the hololive production fan content guidelines assume activity such as doujin (fan) work or activity within the scope of a hobby, and draw the line that anything deemed to be for commercial purposes, or use by a corporation, is not allowed (source: hololive production Guidelines (official), as of July 2026). Because the wording and scope differ for each rights holder, you must always read the target work's guidelines themselves.
Know the "same-day license" system
If you research three-dimensional fan works, you will inevitably come across the "same-day license" (tojitsu hanken). This is a system that grants individuals permission to produce merchandise only on the day of an event. Merchandising rights, which would normally require a formal contract between companies, become available to individuals through the event's organizers.
The official Wonder Festival website explains this system as follows: "Through a special mechanism called the 'same-day license system,' which makes it possible to exhibit and sell works based on IP only on the day of the event, we enable the presentation and sale of a wide variety of character works with the permission of each rights holder." It also states that sales of licensed works are limited to the venue and to the day of the event, and that they cannot be purchased online (source: Wonder Festival Official FAQ, as of July 2026).
The practical implication is clear: if you want to distribute three-dimensional works of licensed characters for a fee, year-round online sales are not part of the picture. Put the other way around, event frameworks like this are also one of the few official routes through which individuals can present three-dimensional works with formal permission.
Three issues specific to 3D models
Once you move to 3D data, issues arise that flat fan art never had.
1. Publishing and distributing the data itself
Posting a flat illustration on social media and distributing 3D model data mean different things. That is because 3D data is closer to a "mold" that the recipient can copy, modify, and print. Even if a set of guidelines allows "posting illustrations," it does not necessarily treat data distribution the same way.
When you read the guidelines, look for whether they include any of the following terms:
- three-dimensional, sculpted works, figures, garage kits
- distribution, sharing, data distribution, providing assets
- modification, redistribution
- commercial, compensation, paid
If none of these terms appear, that use cannot be said to be "explicitly allowed."
2. Sending data to an outside 3D printing service
To produce a physical object, you send your data to a 3D printing service. This amounts to providing that data to a third party. Many printing services state in their terms that it is the user's responsibility to ensure that submitted data has no rights issues. If you submit data of a licensed character, you need to understand that the responsibility comes back to you.
3. Uploading images to an AI service
When you use AI to generate a 3D model from an illustration, you end up uploading an image depicting someone else's character to the service. Here, think about two separate layers.
The first is the terms of use of the service you use. Rights to generated output and whether commercial use is allowed are set by each service, so you need to check what the terms cover. The second is the issue of using someone else's work as input in the first place. Japan's Agency for Cultural Affairs has set out its thinking on generative AI and copyright, and if you use someone else's work as the source or input for generation, the rights in that original work may come into play separately (source: Agency for Cultural Affairs, "AI and Copyright", as of July 2026). Safety and rights considerations when using AI are covered in detail in Safety and Copyright When Using AI to Make Figurine-Style 3D Models from Drawings.
Note that discussion continues on the finer points of rights in AI-generated output, and there are areas where no definitive answer can be given at this time. This article avoids making firm statements on those points as well.
What to check, by use
When you turn fan art into a 3D model, what you need to check depends on what you want to do.
| What you want to do | Main things to check |
|---|---|
| View it only yourself (not published) | Depends on the rights holder's stance. At least there are fewer issues than when publishing |
| Post it on social media as still images or video | The guidelines' conditions on posting and publishing, and whether attribution is required |
| Distribute the 3D model data | Whether the guidelines mention data distribution or redistribution. If not, proceed with caution |
| Print it as a physical object and keep one for yourself | The guidelines' conditions on three-dimensional works, and the printing service's terms |
| Distribute physical copies for a fee | Whether there is a framework such as a same-day license for obtaining permission. Online sales are often not envisioned |
| Sell on an ongoing basis | As a rule, formal permission from the rights holder is required |
The further down the table you go, the more there is to check and the greater the need for permission. First pin down where your goal sits in this table, then read the guidelines; that makes the judgment quicker.
What to do when the guidelines say nothing about 3D works
A common situation is that fan content guidelines have been published, but they say nothing about three-dimensional works or data distribution.
In this case, you cannot read "not mentioned" as "allowed." Guidelines show the range the rights holder allows, and the safe interpretation is that uses not mentioned fall outside that range. Your options are as follows:
- Ask the rights holder. If a contact point is published, explaining your specific use and confirming is the most reliable approach.
- Keep it within a scope where you don't publish or distribute. Limit it to uses that stay entirely with you.
- Go with an original character. If it is a character you own the rights to, none of these checks are needed. For turning original characters into 3D, see How to Turn Your Original Character into 3D.
If even one element still leaves you unsure, it is safest to avoid moving on to unlicensed mass production or sales.
Frequently asked questions
Is it illegal to turn fan art into a 3D model?
It cannot be called uniformly illegal or legal. While it is an act that involves the reproduction and adaptation rights held by the original rights holder, many rights holders allow a certain range in their fan content guidelines. First check the target work's guidelines and read whether they say anything about three-dimensional works or data. If they say nothing, it is safest to consider contacting the rights holder.
Do I need to check even if I'm making it just to enjoy myself?
There are fewer issues than when publishing or distributing, but rights holders' stances differ from work to work. At the very least, you cannot generalize that "anything goes as long as I don't publish it." If you submit the data to an outside service, keep in mind that at that point you are handing the data to a third party.
Is it fine if I distribute the 3D model data for free?
You cannot say it is always allowed just because it is free. Commerciality is one factor in the judgment, but it alone does not decide the conclusion. In addition, distributing data creates a situation where recipients can further copy, modify, and print it, and some rights holders treat it separately in their guidelines. Check whether the guidelines mention distribution or redistribution.
If the guidelines say "no three-dimensional items," can I not even create 3D data?
What that statement covers (only the manufacture and distribution of physical items, or data as well) depends on how the guidelines are worded. If you can't tell, it is safest to check with the rights holder or avoid that use. Not moving ahead while things are ambiguous is the basic stance in this area.
If I take part in a same-day license event, can I keep selling afterward?
According to Wonder Festival's official explanation, sales of works licensed under the same-day license system are limited to the venue and to the day of the event, and they cannot be purchased online. If you want to keep selling after the event, you will need a separate formal arrangement with the rights holder.
If it's an original character, are these checks unnecessary?
If it is an original character you created from scratch, turning it into a 3D model and publishing it are, as a rule, within your own rights. However, there are other things to check: whether it resembles existing famous characters or products too closely, whether it contains elements of real people, and, if the illustration was commissioned, what the contract says.

Summary
Turning fan art into a 3D model involves different checks from flat fan art. There are three key points.
First, many rights holders treat three-dimensional works separately from flat fan art. In Capcom's case, three-dimensional works are included among fan works, but the stated condition is that paid sales of figures and garage kits are limited to events for which the company grants same-day licenses.
Second, there is a system called the same-day license, and sales under it are limited to the venue and the day. Year-round online sales are basically not envisioned.
Third, because a 3D model is "data," it adds the issues of distribution, submission to outside service providers, and uploading to AI services.
And finally, uses that the guidelines don't mention cannot be read as "allowed." When elements remain that leave you unsure, the safe choices are to check with the rights holder or to go with an original character you own the rights to.
