Prusament PETG Ultraglow green is\u00a0the brightest glow-in-the-dark filament on the market.<\/strong>\u00a0It is filled with the highest possible amount of strontium aluminate, which is a safe alternative to previously used Phosphorus. We used the maximum we could achieve while maintaining reliable printability and delivering exceptionally bright luminescence. We felt like there was no strong reason to make another mediocre glow-in-the-dark PLA filament, as the market already has plenty. Instead, we did what we do best: we took it up to eleven.<\/p>\n

Glows all night long<\/h3>\n

Visible glow after 6-8 hours<\/strong><\/p>\n

Prusament PETG Ultraglow can be charged by exposing it to both UV (most effective) and visible light sources. When charged, the filament glows strongly for several minutes, then the glow intensity gradually decreases. In total darkness, a weak glow can be visible even after 6-8 hours after charging.<\/p>\n

Brightest of them all<\/h3>\n

Filled with glowing powder to the maximum<\/strong><\/p>\n

We ordered other branded glowing filaments and put them all to the test. We’ve kept the other brands anonymous, as the results speak for themselves. Prusament PETG Ultraglow shines by far the brightest when compared to common glow-in-the-dark PLA.<\/p>\n

Bonded in Prusament PETG<\/h3>\n

For better mechanical and temperature resistance<\/strong><\/p>\n

We deliberately chose PETG as the base polymer for a reason: it’s stronger than commonly used PLA and resists higher temperatures, making it suitable for functional parts. And you can take it further with the\u00a0XL<\/a>\u00a0and other multimaterial solutions. Print functional models in standard PETG and add glowing accents to highlight specific components – switches, handles, indicators, or any part that needs visibility in low light.<\/p>\n","protected":false},"excerpt":{"rendered":"

Prusament PETG Ultraglow green is our own in-house made filament with \u00b10.04mm manufacturing tolerance. The material is filled with strontium aluminate, which gives it the green glow in the darkness, when charged with light. Filled with maximum amount of the glowing powder, the Prusament PETG Ultraglow Green is the brightest glow-in-the-dark filament on the market.<\/p>\n","protected":false},"featured_media":110621,"menu_order":0,"template":"","acf":[],"_links":{"self":[{"href":"https:\/\/prusament.com\/de\/wp-json\/wp\/v2\/prusa_material\/110578"}],"collection":[{"href":"https:\/\/prusament.com\/de\/wp-json\/wp\/v2\/prusa_material"}],"about":[{"href":"https:\/\/prusament.com\/de\/wp-json\/wp\/v2\/types\/prusa_material"}],"version-history":[{"count":9,"href":"https:\/\/prusament.com\/de\/wp-json\/wp\/v2\/prusa_material\/110578\/revisions"}],"predecessor-version":[{"id":110623,"href":"https:\/\/prusament.com\/de\/wp-json\/wp\/v2\/prusa_material\/110578\/revisions\/110623"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/prusament.com\/de\/wp-json\/wp\/v2\/media\/110621"}],"wp:attachment":[{"href":"https:\/\/prusament.com\/de\/wp-json\/wp\/v2\/media?parent=110578"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
