3DPrintWhat is a web based 3D model aggregator that collects popular and trending designs from several leading 3D printing platforms. Its primary function is to provide a single, unified feed where users can browse and discover printable models without visiting each platform individually. The service currently aggregates content from sources such as Printables, Cults3D, and MakerWorld. The main feature of 3DPrintWhat is its browsable feed of curated, trending models. Users can scan this feed to see what is currently popular across the 3D printing community. The service also allows users to compare similar models across different platforms directly from the aggregated view. For users who wish to keep track of designs, the app offers the ability to sign in and save items to a favorites list for later reference. Browsing the feed is available without an account, while the saving functionality requires a user login. The typical workflow involves a user visiting the 3DPrintWhat site to explore the current selection of trending models. After identifying a model of interest, the user can review its details and compare it with similar offerings from other sources. Once a decision is made, the user is directed to the original platform to download the files and initiate the printing process. The service functions as a discovery and comparison tool, enabling users to efficiently find their next print project from a centralized location.
