'''Digital modeling and fabrication''' is a design and production process that combines [[3D modeling]] or [[Computer-aided design|computing-aided design (CAD)]] with additive and subtractive [[manufacturing]]. Additive manufacturing is also known as [[3D printing]], while subtractive manufacturing may also be referred to as [[machining]],<ref>{{Cite web|title = What is digital modeling and fabrication? - Definition from WhatIs.com|url = http://searchmanufacturingerp.techtarget.com/definition/Digital-modeling-and-fabrication|website = SearchManufacturingERP|access-date = 2016-02-17|language = en-US|archive-date = 2017-07-04|archive-url = https://web.archive.org/web/20170704033717/http://searchmanufacturingerp.techtarget.com/definition/Digital-modeling-and-fabrication|url-status = dead}}</ref> and many other technologies can be exploitedused to physically produce the designed objects.<ref>{{cite journal|last1=Bickel|first1=B.|last2=Cignoni|first2=P.|last3=Malomo|first3=L.|last4=Pietroni|first4=N.|title=State of the Art on Stylized Fabrication|journal=Computer Graphics Forum|date=2018|volume=37|issue=6|pages=325–342|doi=10.1111/cgf.13327|hdl=10453/129681|s2cid=51870522|url=http://vcg.isti.cnr.it/Publications/2018/BCMP18/StylizedFabricationSTAR_Personal.pdf|hdl-access=free}}</ref>

===CNC milling machine===

CNC stands for "computer numerical control". CNC mills or routers include proprietary software which interprets 2D vector drawings or 3D models and converts this information to a [[G-code]], which represents specific CNC functions in an alphanumeric format, which the CNC mill can interpret. The G-codes drive a [[machine tool]], a powered [[Machine|mechanical device]] typically used to fabricate components.<ref>{{Cite web|title = Five CNC Myths and Misconceptions {{!}} Modern Machine Shop|url = http://www.mmsonline.com/columns/five-cnc-myths-and-misconceptions|website = www.mmsonline.com|access-date = 2016-02-17|first = Mike|last = Lynch| date=19 October 2011 }}</ref> CNC machines are classified according to the number of axes that they possess, with 3, 4 and 5 axis machines all being common, and industrial robots being described with having as many as 9 axes. CNC machines are specifically successful in milling materials such as [[plywood]], [[plastics]], [[foam board]], and metal at a fast speed. CNC machine beds are typically large enough to allow 4' × 8' (123&nbsp;cm x 246&nbsp;cm) sheets of material, including foam several inches thick, to be cut.

===Laser cutter===

{{See also|Water jet cutter}}

The laser cutter is a machine that uses a laser to cut materials such as chip board, matte board, felt, wood, and acrylic up to 3/8 inch (1&nbsp;cm) thickness. The laser cutter is often bundled with a driver software which interprets vector drawings produced by any number of CAD software platforms.<ref>{{Cite web |title=Smart Desktop Laser Cutter and Engraver {{!}} xTool Laser |url=https://www.xtool.com/ |access-date=2023-11-30 |website=www.xtool.com}}</ref>

The laser cutter is able to modulate the speed of the laser head, as well as the intensity and resolution of the laser beam, and as such is able in both to cut and to score material, as well as approximate raster graphics.<ref>{{Cite web|title = Automated Laser Cutting {{!}} Precision Metal Industries|url = http://www.pmiquality.com/services/automated-laser-cutting|website = www.pmiquality.com|access-date = 2016-02-17|first = Precision Metal|last = Industries}}</ref>
