Here's a rewritten version of the text: --- Illinois' top fire official, Larry Matkaitis, is pushing for a significant change in the state's building codes by mandating fire sprinklers in all new single-family homes across the state. This proposal has sparked both support and resistance, particularly from the city of Chicago, which has historically resisted such measures due to cost concerns. Matkaitis argues that the proposed changes, which align with national standards set by the National Fire Protection Association (NFPA), are essential for ensuring public safety. "Everyone in Illinois deserves safe housing," Matkaitis stated during a recent interview with NBC Chicago. He noted that many other states have already implemented similar requirements, and Illinois would join California and Maryland as the third state to do so. The fire chief community in Illinois has largely backed Matkaitis' initiative. Mike Falese, president of the Illinois Fire Chiefs Association, emphasized the importance of prioritizing life-saving measures. "The sprinkler initiative in homes is aimed at preserving life," Falese explained. However, Chicago's Fire Commissioner Jose Santiago disagrees, arguing that the city's existing life safety regulations are just as effective. Santiago highlighted several measures already in place, such as mandatory smoke detectors and advanced communication systems in buildings. Despite this, Matkaitis remains firm in his stance, pointing out that the legal framework for statewide fire safety codes predates home rule exceptions. The debate has taken on added urgency given past tragedies. A fire at the Cook County Administration Building in 2003 claimed six lives, prompting an investigation that criticized Chicago's reluctance to enforce comprehensive sprinkler systems. Former FEMA director James Lee Witt, who led the inquiry, stressed the need for immediate action, warning that delays could prove fatal. Meanwhile, opponents of the proposal, including building owners and condo associations, cite financial challenges. Retrofitting older buildings with sprinkler systems could cost millions, a burden they argue outweighs the benefits. Yet, Matkaitis counters that these costs pale in comparison to the potential loss of life and property damage. Interestingly, while Chicago debates these measures, the NFPA held its annual conference in the city. NFPA President James Shannon reiterated the importance of adopting modern fire safety standards, emphasizing that deaths in non-sprinklered buildings are preventable. "Chicago should be the leader on this issue," Shannon urged. "These are great buildings, but more importantly, the people who live in them deserve protection." The tension between state and local authorities highlights a broader struggle over public safety versus fiscal responsibility. As the discussion continues, it remains unclear whether Chicago will ultimately adopt the new regulations, though the push for nationwide uniformity grows stronger with each passing year. --- This version maintains the original message while expanding slightly and refining the tone to sound more conversational and detailed.

Stereo Light Curing Molding - Sla

STEREO LIGHT CURING MOLDING - SLA
It mainly uses photosensitive resin as a raw material, and utilizes the characteristic that liquid photosensitive resin will cure quickly under ultraviolet laser beam irradiation. The photosensitive resin is generally liquid, and it immediately initiates a polymerization reaction and completes curing when irradiated with a certain wavelength of ultraviolet light (250 nm to 400 nm). SLA focuses on the surface of the light-curing material by focusing ultraviolet light of a specific wavelength and intensity to solidify it sequentially from point to line and from line to surface, thereby completing the drawing of a layered cross-section.
