This page includes some links for 3D assets.
- Yeggi, a specialized search engine for 3D printable objects
- Images.google (Only pictures, but search may then lead to 3D websites if you add "3D" or similar to the query)
- Princeton 3D Model Search Engine (not maintained, but ok to find some VRML models for example)
- Yobi3D 3D Model Search Engine (Search by keyword. Provides a viewer to see models in 3D)
3 3D models for 3D printing
- Free from non-commercial entities
- George W. Hart's Rapid Prototyping page includes STL files for (complex) mathematical/geometrical forms. In addition, simpler Makerbot Constructions also are available. Most low end 3D printers can handle these (actually better).
- DefCad. The island of misfit objects, e.g. the famous printable "liberator" gun was there before it got blocked. Such files can be found in places like PirateBay. Btw assembling a gun from "standard" metal parts you could buy in a hardware store is both cheaper and more reliable. I mean it's 15th century tech. I am not in favor of distributing guns to everyone, but one cannot censor Internet (Daniel K. Schneider (talk) 19:49, 10 May 2013 (CEST)).
- Free from commercial entities
- Thingiverse (a place to share digital designs that can be made into real, physical objects). Many interesting objects for filament-based 3D printers. However, since Makerbot started asserting their ownership more strongly in 2012, some people now use other alternatives, e.g. privately controlled file sharing schemes (blogs, portals, github, google drive, web servers, whatever ....)
- YouMagine.com. This repository tied to Ultimaker is similar as thingverse in terms of functionality. Less "proprietary feel" than thingiverse.
- STL downloads at Nunus. (large repository from a filament maker).
- Commercial, also offering free items
- RedPah. Community where designers can share for free or sell.
- Hobby & DIY Free 3D Print Models from cgtrader.
- Sketchfab (some downloadables, most model are only for looking at...)
Online printing services
Most online printing services also include large catalogues of printable objects. Some of these are free to take, most are not.
- Shapeways includes thousands of printable objects.
In addition to repositories for printable objects, you also can try to adapt models made for 3D virtual environments, see below. Finally, various CAD/CAM and 3D modeling software includes sample directories and other models are often available on various official and unofficial support sites.
4 CAD/CAM models
CAM/CAM models include editable source code. Some of the above site's (e.g. Thingiverse) also can include source code.
- Scanned models
- The Stanford 3D Scanning Repository (some files in .PLY format)
- Free CAD models
5 3D Models for virtual environments
This models are made for creating virtual environments, games. etc. Finding free 3D models is the usual "search for multimedia assets" nightmare, 95 of hits are bad if you use google ...)
- Various free 3D model repositories
- http://3dr.adlnet.gov/ Created in the context of SCORM/TLA
- Google 3D warehouse (.dae/collada, .skp)
- Trinckle (a more recent repository for 3D models) .PLY .STL and .3DS
- NTU 3D Model Database ver.1. Free for education (.obj)
- Archive 3D. Very large repository of 3D models. Some can be converted quite easily to printable objects.
- Free models from commercial sites (some sites many include lots of ads, none endorsed)
- Commercial (no endorsement ...)
- Often, these models come in several formats, some are high end and expensive
- The3dStudio.com (some free)
- Artist-3D.com (some free for education)
- DAZ 3D has some free models (registration required) for DAZ Studio.
