* PMMA, in the commercial form Technovit 7200 is used vastly in the medical field. It is used for plastic histology, electron microscopy, as well as many more uses.
* PMMA has been used to create ultra-white opaque membranes that are flexible and switch appearance to transparent when wet.<ref>{{cite journal |last1=Syurik |first1=Julia |last2=Jacucci |first2=Gianni |last3=Onelli |first3=Olimpia D. |last4=Holscher |first4=Hendrik |last5=Vignolini |first5=Silvia |date=22 February 2018 |title=Bio-inspired Highly Scattering Networks via Polymer Phase Separation |journal=Advanced Functional Materials |volume=28 |issue=24 |page=1706901 |doi=10.1002/adfm.201706901 |doi-access=free}}</ref>
* Acrylic is used in tanning beds as the transparent surface that separates the occupant from the tanning bulbs while tanning. The type of acrylic used in tanning beds is most often formulated from a special type of polymethyl methacrylate, a compound that allows the passage of ultraviolet rays.
* Sheets of PMMA are commonly used in the sign industry to make flat cut out letters in thicknesses typically varying from {{convert|3|to|25|mm|in|1|sp=us}}. These letters may be used alone to represent a company's name and/or logo, or they may be a component of illuminated channel letters.  Acrylic is also used extensively throughout the sign industry as a component of wall signs where it may be a backplate, painted on the surface or the backside, a faceplate with additional raised lettering or even photographic images printed directly to it, or a spacer to separate sign components.
* PMMA was used in [[Laserdisc]] optical media.<ref>{{cite book |url=https://archive.org/details/howelectronicthi00good_0 |url-access=registration |quote=PMMA Laserdisc. |title=How Electronic Things Work...

* [[Plastic optical fiber]] used for short-distance communication is made from PMMA, and perfluorinated PMMA, clad with fluorinated PMMA, in situations where its flexibility and cheaper installation costs outweigh its poor heat tolerance and higher attenuation versus glass fiber.
* PMMA, in a purified form, is used as the matrix in [[laser dye]]-doped organic solid-state gain media for tunable [[solid state dye lasers]].<ref>[[F. J. Duarte|Duarte, F. J.]] (Ed.), ''Tunable Laser Applications'' (CRC, New York, 2009) Chapters 3 and 4.</ref>
* In [[semiconductor]] research and industry, PMMA aids as a [[resist (semiconductor fabrication)|resist]] in the [[electron beam lithography]] process. A solution consisting of the polymer in a solvent is used to [[spin coating|spin coat]] [[silicon]] and other semiconducting and semi-insulating wafers with a thin film. Patterns on this can be made by an electron beam (using an [[electron microscope]]), deep UV light (shorter wavelength than the standard [[photolithography]] process), or [[X-ray]]s. Exposure to these creates chain scission or (de-[[cross-link]]ing) within the PMMA, allowing for the selective removal of exposed areas by a chemical developer, making it a positive photoresist. PMMA's advantage is that it allows for extremely high resolution patterns to be made. Smooth PMMA surface can be easily nanostructured by treatment in oxygen [[radio-frequency plasma]]<ref name="vacuum2010">{{cite journal |doi=10.1134/S1027451010010015 |title=Vacuum ultraviolet smoothing of nanometer-scale asperities of poly(methyl methacrylate) surface |year=2010 |last1=Lapshin |first1=R.

* PMMA is used as a shield to stop beta radiation emitted from radioisotopes.
* Small strips of PMMA are used as [[dosimeter]] devices during the [[gamma ray|Gamma]] Irradiation process. The optical properties of PMMA change as the gamma dose increases, and can be measured with a [[spectrophotometry|spectrophotometer]].
* [[black light|Blacklight]]-reactive [[UV tattoo]]s may use [[tattoo ink]] made with PMMA [[micro-encapsulation|microcapsule]]s and [[Fluorescence|fluorescent]] dyes.<ref>{{Cite journal |last1=Bedocs |first1=Paul M. |last2=Cliffel |first2=Maureen |last3=Mahon |first3=Michael J. |last4=Pui |first4=John |date=March 2008 |title=Invisible tattoo granuloma |url=https://pubmed.ncbi.nlm.nih.gov/18441850/ |journal=Cutis |volume=81 |issue=3 |pages=262–264 |issn=0011-4162 |pmid=18441850}}</ref>
* In the 1960s, [[luthier]] [[Dan Armstrong]] developed a line of electric guitars and basses whose bodies were made completely of acrylic. These instruments were marketed under the [[Ampeg]] brand. [[Ibanez]]<ref>[http://www.ibanezregister.com/Gallery/js/gal-js2k.htm JS2K-PLT] {{webarchive|url=https://web.archive.org/web/20070928120415/http://www.ibanezregister.com/Gallery/js/gal-js2k.htm |date=2007-09-28}}. Ibanezregister.com. Retrieved 2012-05-09.</ref> and [[B.C. Rich]] have also made acrylic guitars.
* [[Ludwig-Musser]] makes a line of acrylic drums called Vistalites, well known as being used by [[Led Zeppelin]] drummer [[John Bonham]].
* [[Artificial nails]] in the "acrylic" type often include PMMA powder.<ref>{{cite book |title=Australian nail technology |last=Symington |first=Jan |publisher=Tertiary Press |year=2006 |isbn=978-0864585981 |location=Croydon, Victoria, Australia |page=11 |chapter=Salon management}}</ref>
* Some modern briar, and occasionally meerschaum, tobacco pipes sport stems made of Lucite.
* PMMA technology is utilized in roofing and waterproofing applications. By incorporating a polyester fleece sandwiched between two layers of catalyst-activated PMMA resin, a fully reinforced liquid membrane is created ''in situ''.
* PMMA is a widely used material to create [[deal toy]]s and [[tombstone (financial industry)|financial tombstones]].
* PMMA is used by the [[Sailor (pen company)|Sailor Pen Company]] of [[Kure, Hiroshima|Kure, Japan]], in their standard models of gold-[[nib (pen)|nib]] [[Fountain Pen|fountain pens]], specifically as the cap and body material.
