Have not tried.

Will just make you aware that the fumes from a cutting styrene is properly not the most healthy to breathe, so be careful.

If I can cut it, I am working on an exhaust system.

i think the consensus was that once it broke the surface it would begin refracting and would stop cutting resulting in a shallow cut no matter what you do.  I never tried it myself.

Pretty much go with “NO”.

Being cheap (not frugal) by getting a inadequate laser to melt/burns/char a plastic sheet is not the way to go.

Get a 40w or higher power laser.

 Styrene/ABS...It is not recommend to be cut by amateurs and when cut it leaves a slightly melted edge which has to be sanded  smooth. 

Fumes need to be ventilated  via proper ventilation to  the outside via a closed system.

Quote from WIKI mentioned above post..

Various regulatory bodies refer to styrene, in various contexts, as a possible or potential human carcinogen. The International Agency for Research on Cancer considers styrene to be "possibly carcinogenic to humans".
 
Chronic exposure to styrene leads to tiredness/lethargy, memory deficits, headaches and vertigo.


...altho the latter  side effects  are also known in teenagers as a natural occurence  ;D ;D

Lasers are wonderful machines..not ONLY  can they cut a finger off BUT  they can also cauterise it at the same time.....

Has anyone cut Styrene Plastic?

i cut .060 styrene 12 hrs a day, 7 days a week
i use several 2.5 watt lasers to do it

i have all my lasers on a 98% enclosed porch leaving 4" around the top open to the air

if i stay close to the lasers the fumes give me a sore throat in 30 minutes or so

i cut very intricate designs @ full power, 90mm/min, 2 passes
the cuts are super clean and the pieces fall out when i lift the material. there is zero cleanup
the side facing the laser has a very slight upward curl that is not visible to anyone but me

at 85 mm/min the curl is more visible and the cut is not as clean

i also cut 1.5mm plexiglass every day with the same lasers. same speed but 3 passes

my lasers never get hot with the factory 40mm fans on them

Interesting...Whilst I agree it is perfectly possible to cut styrene..the health problems accruing from the fumes remain a problem.........Do you have a "name" for the styrene  that you use? manufacturer? and are you positive it IS styrene
(ABS)   Acrylonitrile butadiene styrene (ABS)

SIBE-R PLASTIC SUPPLY

BLACK POLYSTYRENE, .060" Thick 24" x 48" PLASTIC SHEET STYRENE

been cutting this for years 12 hrs a day, 7 days a week

once again, if you breath the fumes it gives you a sore throat

i dont breath the fumes

my laser room is vented to the outside very well and i have zero issues

an un-vented room would be a big mistake :)

i have laser  cut some abs and it is totally evil. i only cut it on one of my cnc mills now.

I think there is confusion here.   
Most people understand that POLYstyrene is different to ABS.
 The original question ,referred to styrene (WAS this meant to be ABS (styrene)?   (I assumed it was).... ..and that -  I think -  has caused confusion.

 (I would certainly avoid cutting POLYstyrene that's for sure!!  also.. cutting ABS (and some other materials) does require a well ventilated operating area (enclosure) with fumes from cutting being vented outside..

This particular query has been aired in this forum previously in regard to cutting ABS.

 It's a case of looking in SEARCH for answers first, as opposed to just asking a question straight off which seems, in this case, to be the original question lacking  in detail of the type of styrene required to be cut

 Google is also a good source of information to such questions as this and gives a lot more detail of hazards of materials being dealt with by laser.

PVC is even worse, it develops at high temperature hydrochloric acid - be careful

Hydrochloric acid as such, is not hazardous to health, provided you do not take a bath in the liquid.

Styrene develops vapor/smoke that is suspected of being highly cancer-inducing. You probably do not notice that before after 10-40 years!   ;)
