As 3D printing expands into more technical and industrial sectors, safety standards are becoming just as important as precision and performance. One of the most critical requirements in certain industries—especially electronics, automotive, and aerospace—is flame retardancy.
But what does it actually mean for a resin to be flame retardant? And more importantly, when do you need it?
What is a Flame Retardant Resin?
Flame retardant resins are photopolymers that resist ignition, limit flame spread, and self-extinguish. They’re often tested and rated using:
-
UL 94 (Vertical Burning Test)
-
V-0, V-1, V-2 classifications
-
Glow Wire or IEC standards
At Resine-3D, our flame-retardant options are free from halogens and compliant with EU safety regulations.
How Do They Work?
These resins contain additives such as:
-
Phosphorus-based retardants
-
Intumescent agents
-
Ceramic fillers
These either interrupt the combustion process or create a barrier that slows or stops fire.
When to Use Flame Retardant Resin
You should consider flame retardant materials when printing:
-
Electronic housings and casings
-
Automotive or aerospace components
-
Battery enclosures
-
Functional prototypes near heat sources
-
Appliances or lighting fixtures
Why Standard Resins Aren’t Enough
Standard resins are combustible and not designed to withstand high heat or flame. Even engineering resins may lack proper fire resistance unless certified.
Resine-3D Flame Retardant Resin
Our flame retardant resins are:
-
High-temperature resistant
-
UL 94 compliant (V-0 available)
-
Dimensionally stable and easy to print
-
Low-smoke and low-toxicity certified
They’re ideal for engineers, prototypers, and safety-conscious manufacturers.
Print Smart. Print Safe.
Fire resistance is not optional in regulated industries. Choosing the right resin protects your product—and the people using it.
