buyers, be careful in the world of non-free 3D models / Habr

There are more 3D models you can find online than you can imagine. But what about paid models? Putting a model somewhere and placing a "buy" button next to it is no longer a problem, but after spending some time buying and printing various non-free 3D models, I began to see some obvious shortcomings of this system.

The specific problems and solutions depend on how these models are marketed, but one thing is clear: Poorly designed 3D models are bad for both consumers and the future pay-per-download market.

Different ways to sell models

There are many ways to sell models online. Online stores are great for digital models because they are not physical goods, and serving a thousand customers is no different than serving ten. Technically, the user pays for a license to use the model, and its conditions vary significantly depending on the creators and intermediaries.

Direct sales with payment per model

Direct selling is similar to downloading 3D models, only before you receive the link, you will see the price of the link. Sites like Cults3D and MyMiniFactory allow creators to set their own prices for non-free models. It is quite difficult to estimate the number of their sales, but the number of downloads for popular models is measured in hundreds or thousands.

Standing apart is the successful Hero Forge project, which allows users to create their own miniatures for board games using a web interface. Users can pay to download the STL file for the model they have created, or buy a printed version. Hero Forge is proprietary, but very successful, judging by their recent Kickstarter campaign.

Indirect sales with payment for access to models

Indirect sales mean that customers pay for access rather than buying models one by one. Successful creators make models in niche areas, and people pay to access their creator's library of work.

The usual way to manage monthly subscribers and provide access to files for 3D modelers is through Patreon. One common niche is board games, and some of the most successful creators have thousands of followers.

Another way of indirect sales is crowdfunding. Money is collected to create a certain set of models, and sponsors get access to the resulting files. Again, there are a lot of miniatures of heroes and territories for desktops.

Self-printing kits

With this approach, 3D models are sold as part of a larger product. The buyer purchases the kit and prints plastic components for it himself, while the kit may contain electronic components and other parts. The result is a set that can include fewer items, is easier to produce, cheaper to ship, and usually costs less than if the seller had to do everything themselves.

Bulwark Blaster (NERF compliant) and OpenScan (open source 3D scanner) are examples of this business model. In both cases, the designs are based on 3D printed components and specific parts lists. The purchaser usually acquires a license to use one copy of the product.

And what's the problem?

In an ideal world, 3D printers reliably print parts of any shape without problems with overhangs, bridges, distortions or supports. You can buy a 3D model and get exactly what you expected. Unfortunately, we have not yet reached this point.

Quality 3D models need to be developed specifically for 3D printing, especially when it comes to money - because under the current system, all the risks fall on the buyers.

No test drives, no fitting rooms, no refunds

The world of non-free 3D models is like a clothing store without fitting rooms, or a car dealership without a test drive. “No money back” is a common phrase in sales and services, but when combined with the inability to try the product before buying, the result can be disappointing if the quality of the model turns out to be poor.

Low technology models

3D printers, like any tool, are good in some situations, not bad in others, and terrible in others. This means that models intended for 3D printing need to be designed taking into account the strengths and weaknesses of 3D printers. About the model developed in this way, we can say that it is made with high manufacturability.

If the model was not designed with 3D printing in mind, it could create problems for the person trying to print it. The problem is that it is not always possible to identify models with which problems will arise, only by their image. Here are two examples.


This model will require struts and post-processing regardless of print orientation. The problem here is subtle: it was designed in such a way that it is almost impossible to print without props, regardless of the print orientation. She has other problems, but more on that later.

Let's add props - and we will face the need for post-processing and poor surface in the places where they were attached. If you place them on the visible side, the detail will be ugly. If it is invisible (where the loop is), they will hardly fit there.

These problems are solved in post-processing, but the point is not that - but that it would be better to avoid these problems while developing the part.


Cut in half, colors added to contrast inner and outer layers. The model is not complete. The problem arises where there are gaps between the outer and inner layers.

Second example. This model was advertised as being compatible with SLA (Laser Stereolithography). FDM and SLA printers have very different benefits, so it was interesting to see a model specifically designed for SLA.

But disappointment awaited me. The model was not solid. There are gaps between the outer layer of the model (the clothes of the figure) and the inner layer (the body), since these layers were modeled separately - and they left it that way.

Uncured material accumulates in these gaps, and the surrounding parts of the model are very thin, which directly attracts imperfections in printing. Such a scheme of the model ensures that, most likely, its outer layers, those that are visible from the outside, will suffer during printing. And these problems were not visible until the model was paid for.

Issues like this and more show poor manufacturability that you can't see in screenshots and renders, and as I noted earlier, pay-per-download is now territory of no refunds and dangers for buyers.

Why poor quality models are a big problem

The problem with bad models is this: by the time it turns out that the model has a problem (or it cannot be made properly, or it is too wasteful to print), it turns out that the buyer has already invested much more in it than just the purchase price. A bad model only repels a person who wants to hit the "Buy" button.

Passing all the risk on the buyer, so that all his money and efforts go to waste - this should be the last thing on any platform seeking to grow.

Ways to improve the situation

It's tempting to try to solve this money-back problem with a file access control system, but then it becomes suspiciously DRM-like, and that's not likely to be a good way forward.

On the other hand, it is possible to increase confidence in the quality of models and purchases without changing too much in current platforms. Here's what you can do.

Demonstrate the quality of models with photographs and documentation

Documentation and a photo of the printed results, rather than just rendering models on a computer, is an effective way to provide the buyer with additional information about the model. The documentation does not have to be extensive, but it should list design elements, assemblies, or areas that require special control. An example is a printable vise model by Christoph Leimer. This is a free model, but its excellent documentation inspires confidence in its quality.

Models that require additional components must clearly list them in the description, along with specifications and sources. The latch model I used as an example of poor manufacturability requires some sort of arcane spring, with no dimensions or where to find it. This is another problem that comes to light too late.

If the developer has not clearly and clearly demonstrated that he successfully printed his own development, do not buy it.

Provide test drive parts

Designers of kits and other prefabricated structures can give free access to some components, as if to say, "if you can print and assemble these models, then you will succeed, because the principles for developing my product were the same." If customers cannot return purchases, then this approach will at least give them a semblance of a test drive.
