== Introduction ==

According to [http://www.rolanddga.com/products/scanners/mdx15/ Roland] milling machines manufacturer, retrieved 16:03, 15 February 2012 (CET), {{quotation|Subtractive Rapid Prototyping (SRP) - starting with a solid object and removing unwanted material - has several advantages over traditional rapid prototyping. Significantly less expensive than rapid prototyping machines with the same resolution, SRP machines mill a wider range of materials that cost less and have no need for chemicals or post finishing work. Plus, they produce a superior finish.}}

One probably should distinguish between
* '''mills for hobby users''' (i.e. serious mills that can cut into hard materials). Such machines are available from about $1000.
* '''Mills for creating models as alternative to 3D printing'''. We are interested in the latter, i.e. devices that could be used in an office, a classroom or in the living room. Therefore '''hobby mill''' in this article refers to a mill that can carve out soft materials.
* Many hobby mills are just some kind of carving machine, i.e. can cut down.
* Routers are similar devices, i.e. rather some kind of cutting machine. They include a larger surface and a smaller z-axis.
* Lathes rotate the workpiece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation ([http://en.wikipedia.org/wiki/Lathe Lathe] Wikipedia).

'''Do not trust this''' yet. So far, I don't have any experience/knowledge about this technology - [[User:Daniel K. Schneider|Daniel K. Schneider]] 16:03, 15 February 2012 (CET)

== Hardware ==

All the entries concern hobby mills, i.e. not the kind you would use to work with steel and other dangerous materials.

The list is far from being complete, but the listed models should provide an idea about what kind of soft materials mills are available.

=== Entry level consumer mills ===

==== Roland iModula ====

[http://www.rolanddg.com/news/nr111005_im-01.html Roland iModela iM-01 Hobby Mill].

* Price: About $1000, 600 Euros
* Cutting area: 4 x 3 inches (1.5 in vertical). This is rather small.
* Includes the iModela Creator design software
* Materials: Wax, plastic, light wood, etc.
* Support site: [http://icreate.rolanddg.com/ http://icreate.rolanddg.com]
* As of feb 2012, the [http://www.rolanddg.be/ EU support site] doesn't include a usable list of national redistributors ...

This model has a reputation of milling very slowly, e.g. days for a smaller model.
