Stranger Things 3D Printing: Models & Ideas
This text summarizes concisely what is meant by such 3D prints, which technology you need, and where the most important legal boundaries lie. The goal is not to scare you, but to give a clear overview so that you can consciously decide what you want to print.
Introduction & Basics
When talking about Stranger Things 3D printing here, it refers to two things: First, the official 3D printed models used for effects, such as the Demogorgon, which was produced by Aaron Sims Creative as a physical monster model using stereolithography resin printers ( Formlabs, Artpublika Mag). Second, it refers to fan models – figures, dioramas, or cosplay props – produced privately with one's own printers.
The series Stranger Things is set in the 1980s in the fictional small US town of Hawkins, combining mystery, horror, and coming-of-age, and is one of the most successful in-house productions of the streaming service Netflix (Wikipedia).
Technology & Application
Technically, these are usually 3D models in STL format that you download from the internet or model yourself and then build up layer by layer on a printer. FDM printers melt plastic filament and deposit material track by track ( Wikipedia). Resin or SLA printers cure liquid resin with UV light and achieve very fine details, making them particularly interesting for monster heads, faces, and miniatures ( (Wikipedia, Formlabs).

For the production itself, creatures like the Demogorgon were first digitally modeled and then printed out in several parts using SLA resin printers, assembled, and painted, to have a tangible figure on set that was combined with digital effects ( (Formlabs, 3D Printing Industry).

This video shows step by step how a Demogorgon figure is created, from the file to the painted model, making the entire process very clear ( (YouTube).
In parallel, a large maker scene has developed that designs and shares suitable figures, dioramas, or lettering as files; search engines for 3D models list thousands of hits for this, many explicitly for miniatures and collectible figures ( (All3DP, TechRadar). This brings the series' motifs into the living room, onto the gaming table, or as decoration on the shelf – relatively low-threshold technically, as long as a suitable printer is available.
Legal Aspects
For many fans, 3D printing is a way to experience the series more personally: A self-painted Demogorgon figure, a small piece of the “Upside Down” as a diorama, or a cosplay prop feels different from mass-produced bought goods. At the same time, the technology allows for variations that the official merch catalog does not offer at all – such as scenes tailored exactly to one’s own shelf dimensions or special poses.
On the part of the rights holders, the focus is on control over the brand and business model. Figures, logos, and designs are protected by copyright, design, and trademark law, and official licenses for merchandise are an important source of revenue ( (WIPO). When fans start selling printed figures, the line between fan project and unofficial product quickly blurs. That’s why brands like Netflix in ihren Brand-Guidelines darauf, dass Logos und andere Markenelemente nicht ohne ausdrückliche Erlaubnis auf physische Produkte gedruckt werden dürfen (brand.netflix.com).

It is documented that resin 3D printing was used in the series itself to build prototypes and large monster figures before digital effects were added ( (Formlabs, Artpublika Mag).
It is also well documented that FDM and SLA printing have two different focuses: FDM is cheaper and robust, resin printing delivers finer details, but requires more post-processing and caution when handling resin ( (Formlabs, Eufy Make).
Legally, it is clear that copying and publicly offering models that replicate protected figures or logos fall within the scope of intellectual property. A study commissioned by the EU Commission and analyses by specialized law firms emphasize that both CAD files and prints can be relevant under copyright or design law as soon as they reproduce protected templates ( (European Commission, MLL Legal, Hogan Lovells).
However, the widespread assumption that fan art is automatically allowed as long as it is “only” sold in small quantities is untenable. Specialist articles on 3D printing and copyright make it clear that even fan-based derivative works can infringe rights without a license if they are clearly based on a protected template ( (WIPO).
Community & Controversies
This legal framework is quite controversially discussed within the community. Some see fan models primarily as free advertising for the brand, while others report removed offers or warnings when figures or logos appeared in online shops without permission ( (WIPO).

On the corporate side, brands try to appreciate creative fan culture while setting clear boundaries. Netflix communicates in its brand guidelines that the use of brand assets on physical products is subject to approval, but always suggests that humor and fan love are welcome as long as protected rights are respected ( (brand.netflix.com, about.netflix.com).
Despite numerous expert opinions, not every detail question has been clarified. Discussions revolve around, for instance, how far private exceptions extend for three-dimensional works and whether blanket fees on devices or materials should play a role when more and more people are printing at home ( (European Commission).
It is also open whether large brands will specifically offer programs for non-commercial fan prints in the future – such as clear approvals for certain motifs or platforms. The current discussion in IP specialized circles shows that a field of tension remains here: On the one hand, fan projects are valuable for connecting to the universe, but on the other hand, rights holders must consistently protect their brands ( (WIPO, Hogan Lovells).
Conclusion & Recommendations
For you, this means: Technically almost everything is possible, but not everything is legally allowed. If you only print models privately for yourself, you are moving in a less critical area in many countries, even if details about private 3D printing are still being legally discussed ( (European Commission). As soon as you sell prints or offer them publicly, trademark, design, and copyright laws become central. (WIPO).
Practically, a simple three-step process helps: First, read the file license – many STL models are explicitly released only for private use. Second, check whether logos or exact figures from the series are really necessary or if a free, inspired interpretation is sufficient. Third, for planned sales, seek legal advice in case of doubt or look for official licensing opportunities (

This video explains step by step how resin 3D printing works for miniatures – from preparation to post-processing – and complements the legal and content-related classification with very concrete practice ( (YouTube).
In short: 3D printing makes the world of Hawkins tangible – technically through FDM and resin printers, in terms of content through creativity and attention to detail. Documented examples from production show how strongly this technology is already anchored in the film world today ( (Formlabs).
For you, this means: You can realize your own models with manageable effort, as long as you are aware of whether you are tinkering privately or venturing into a commercial area. Anyone who reads licenses, respects brand guidelines, and makes conservative decisions when in doubt can have a lot of fun with Stranger Things 3D prints – without taking unnecessary legal risks ( (brand.netflix.com, WIPO).
