2. The Problem
Given the increasing number of people working with 3D printers in both professional and personal settings, ensuring that users are protected from the harmful effects of these emissions is of paramount importance. This concern is central to RatRig’s focus on developing safer, healthier solutions for its customer base.

🔴 Ultrafine Particles (UFPs)
UFPs are small enough to bypass the respiratory system’s natural defenses and can accumulate deep within the lungs. Studies have shown that prolonged exposure to UFPs can result in respiratory issues, cardiovascular problems, and other long-term health effects
🔴 Toxic Gases (including VOCs)
Many 3D printing materials release formaldehyde, styrene, and other carcinogenic compounds when melted. These toxic fumes can pose serious risks to users, especially in poorly ventilated environments
RatRig, committed to delivering premium, customizable 3D printers, recognized that existing filtration solutions didn’t meet their high standards for user safety and print quality. The lack of an effective system for filtering ultrafine particles, toxic gases, and odors was a key challenge that needed to be addressed for a safer, more comfortable user experience
