Results show significant variation even within the same material type — for example, Prusa Galaxy Black PLA required a blowtorch to ignite while Elegoo PLA+ burned readily, and HTPLA self-extinguished. TPU was the least flammable solid filament, while foam TPU burned most aggressively. ABS, ASA, and HIPS burned readily with sooty flames. PETG and regular TPU are recommended for applications where fire resistance matters. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Which 3D printing filament is most fire resistant? PETG and regular TPU are the most fire-resistant common filaments. Regular TPU resisted ignition even from a blowtorch, only melting. PETG also resisted ignition readily. By contrast, ABS, ASA, and HIPS burn aggressively with sooty flames, and standard PLA burns easily. HTPLA showed self-extinguishing behavior after blowtorch exposure, making it another option worth considering. _Makers choosing filaments for fire-sensitive applications track material comparisons like this on daily.dev._ ### Does ABS or PETG burn more easily when exposed to flame? ABS burns far more readily than PETG. ABS ignites easily and burns with a sooty yellow flame, similar to ASA and HIPS. Black PETG, by contrast, resisted ignition and was difficult to light even with direct flame exposure. If fire resistance is a concern, PETG is the significantly safer choice between the two. _Engineers deciding between ABS and PETG for real-world parts find material safety comparisons like this on daily.dev._ ## Similar posts on daily.dev - [Your 3D prints are failing because you're using the wrong material, and PLA is the culprit](https://daily.dev/posts/your-3d-prints-are-failing-because-you-re-using-the-wrong-material-and-pla-is-the-culprit-f2hwobruy) · XDA Developers · 0 upvotes · 0 comments - [PETG: The PLA Filament Alternative That Just Works](https://daily.dev/posts/petg-the-pla-filament-alternative-that-just-works-xjq7gije3) · Hackaday · 0 upvotes · 0 comments - [I kept reaching for the strongest filament when PETG was the right call all along](https://daily.dev/posts/i-kept-reaching-for-the-strongest-filament-when-petg-was-the-right-call-all-along-ojjwkvb4u) · XDA Developers · 0 upvotes · 0 comments - [I've been 3D printing for 3 years, and PETG is the only filament I print functional parts in now](https://daily.dev/posts/i-ve-been-3d-printing-for-3-years-and-petg-is-the-only-filament-i-print-functional-parts-in-now-mnfebq2ij) · XDA Developers · 0 upvotes · 0 comments - [Printing FDM Filaments That Are Just Plain Weird](https://daily.dev/posts/printing-fdm-filaments-that-are-just-plain-weird-lyyw6vtb8) · Hackaday · 0 upvotes · 0 comments --- [View this post on daily.dev](https://daily.dev/posts/lighting-3d-printed-parts-on-fire-for-science-7lmhe862a) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Lighting 3D Printed Parts On Fire For Science","url":"https://daily.dev/posts/lighting-3d-printed-parts-on-fire-for-science-7lmhe862a","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/lighting-3d-printed-parts-on-fire-for-science-7lmhe862a"},"datePublished":"2026-08-12T08:28:02.229Z","dateModified":"2026-08-12T08:28:24.703Z","description":"An experiment testing the flammability of common 3D printing filaments including PLA, PETG, ABS, ASA, TPU, and PEBA.
