 ===== How do I do that? =====
-The first step will be to look up the Material Safety Data Sheets [MSDS] for the material you want to cut.  This will list all hazards related tot he material and, more importantly to us, what it will break down into when heated.  Fortunately, they are required to be provided by the manufacturer. unfortunately, there isn't a central collection of them to search without paying for the convenience so you will have to hunt them down.

 For this example we'll research Worbla, which is a brand name thermoplastic.

   * After messaging them, they sent {{:tool:laser_cutter:worbla_blackart_msds.pdf|this PDF}}.
   * This one does not list "thermal degradation products", so we have to go the long way and follow the breadcrumbs for the compounds listed under "Composition".  Namely:  Caprolactone-polymers, ethylene-vinyl acetate (EVA), polyester terephtalate

           * Here we get some disappointing news: "Hazardous in case of skin contact (irritant), of ingestion, of inhalation"
    * This is where we go to the LCC for the decision.  Message them with something along the lines of "I would like to get Worbla approved for the laser cuter.   Below are links to the material itself and all of its byproducts.  Thanks for all of your hard work, we all we you a beer!" and hope for the best.
