The primary fire risk associated with resin printers is the heater used during winter, whereas the primary fire risk of a FDM printer is the bed and hotend. An enclosure made of fabric, acrylic, or wood is vulnerable to fire but is affordable and easy to work with. An enclosure made of metal, glass, or mineral wool will be fire resistant. All 3D printers should remain under supervision while in use, and it is recommended to have a smoke detector and fire extinguisher.
