Ever since its launch, Printables.com has stood out with its sleek design, intuitive categorization system, and a well-thought-out reward program for quality models. These features quickly began to attract users from other, previously dominant, 3D model-sharing platforms.
But alas, as the platform grew, new problems inevitably appeared. With the rising number of uploads came an increasing flood of junk – models that serve no purpose whatsoever, yet their authors, for reasons known only to them, decide to publish. You’ll find everything from basic geometric shapes to random doodles thrown together in Tinkercad that look (and probably are) made by preschoolers, then shared with the world to admire. Don’t get me wrong – it’s great to start learning early, but such models don’t belong on Printables.com!
Categories, originally designed to help users focus on their interests and discover some hidden gems, are slowly but surely becoming cluttered with models that simply don’t belong there. Sometimes it’s just misunderstanding the meaning of the category: For instance, the “3D Printers >> Accessories” section is flooded with random keychains and similar. Technically, they are all “accessories,” but they’re certainly not “3D printer accessories”. Other times, it’s pure carelessness, where a category is chosen just to fill the field, which is unfair to the community.
But more often than not, I see users deliberately choosing the most popular categories to increase visibility of their “masterpieces”. As a result, sections like “Parts & Upgrades for Original Prusa printers” are polluted with utterly useless junk. True, nobody really cares about them, so they eventually sink to the bottom of the list, but meanwhile, they clutter the space.
Another growing issue are AI-generated models. At first glance, some of them might look appealing, so people intuitively hit “like” – usually because only shiny 3D renders are shown, not actual printed results. Thus, those models climb the Trending list, even though most are wrongly categorized and completely unprintable.
Then there’s the rise of “fake makes”. With the introduction of reward points for sharing printed results, countless users now upload photos stolen from the original creator, adding a lazy comment like “works great” or “thanks, superb!” – just to collect points.
And the latest plague? Spam. Ads that have nothing to do with 3D printing are being posted by fake accounts and bots, increasingly littering the platform and even its homepage.
Yes, there is a reporting option – I use it regularly – but moderation often takes days, and let's face it – a vast majority of people just don't care enough to click on the “Report” button! There’s simply too much content to handle manually without hiring an army of moderators, and it feels like Printables.com is beginning to outgrow itself. And all that is pushing more and more users just further away…
That’s why it might be a good idea for the Prusa team to invest some time and resources into building an AI-backed moderation system that could automatically filter out such content. It is absolutely doable! Of course, human moderators would still be needed to handle disputes, since nobody wants Printables to turn into another AI moderation disaster like Facebook.
I believe the time is now – perhaps even the last chance – to save Printables.com from becoming a digital junkyard where trash overwhelms valuable 3D models.
