==Processing options==
PEEK melts at a relatively high temperature (343&nbsp;°C / 649.4&nbsp;°F) compared to most other thermoplastics. In the range of its melting temperature it can be processed using [[injection moulding]] or [[extrusion]] methods. It is technically feasible to process granular PEEK into filament form and 3D printing parts from the filament material using [[fused deposition modeling]] – FDM (or fused filament fabrication – FFF) technology.<ref>{{cite web|last1=Newsom|first1=Michael|title=Arevo Labs announces Carbon Fiber and Nanotube-reinforced High Performance materials for 3D Printing Process|url=http://www.solvay.com/en/media/press_releases/20140324-Arevo.html|website=Solvay Press Releases|date=24 March 2014 |publisher=LouVan Communications Inc.|access-date=27 January 2016}}</ref><ref>{{cite web|last1=Thryft|first1=Ann|title=3D Printing High-Strength Carbon Composites Using PEEK, PAEK|url=http://www.designnews.com/author.asp?section_id=1392&doc_id=272706&dfpPParams=ind_183,industry_aero,industry_gov,industry_medical,bid_27,aid_272706&dfpLayout=blog&dfpPParams=ind_183,industry_aero,industry_gov,industry_medical,bid_27,aid_272706&dfpLayout=blog|publisher=Design News|access-date=27 January 2016|archive-date=2 February 2016|archive-url=https://web.archive.org/web/20160202074713/http://www.designnews.com/author.asp?section_id=1392&doc_id=272706&dfpPParams=ind_183,industry_aero,industry_gov,industry_medical,bid_27,aid_272706&dfpLayout=blog&dfpPParams=ind_183,industry_aero,industry_gov,industry_medical,bid_27,aid_272706&dfpLayout=blog|url-status=dead}}</ref> PEEK filaments have been demonstrated for producing medical devices up to class [[medical devices|IIa]].<ref>[http://www.indmatec.com/press/peek-filament-medtec Press release Indmatec PEEK MedTec]{{Dead link|date=December 2024 |bot=InternetArchiveBot |fix-attempted=yes }}.</ref> With this new filament, it is possible to use the FFF method for different medical applications like [[dentures]].

In its solid state PEEK is readily machinable, for example, by [[CNC]] [[milling machines]] and is commonly used to produce high-quality plastic parts that are thermostable and both electrically and thermally insulating. Filled grades of PEEK can also be CNC machined, but special care must be taken to properly manage stresses in the material.

PEEK is a [[high-performance plastics|high-performance polymer]], but its high price, due to its complex production process, restricts its use to only the most demanding applications.<ref>{{Cite journal |last1=Yin |first1=Jun |last2=Zhang |first2=Aiqing |last3=Liew |first3=Kong Yong |last4=Wu |first4=Lihua |date=2008 |title=Synthesis of poly(ether ether ketone) assisted by microwave irradiation and its characterization |journal=Polymer Bulletin |volume=61 |issue=2 |pages=157–163 |doi=10.1007/s00289-008-0942-6 |s2cid=97563069 |issn=1436-2449}}</ref>
