Figure 4 Tough 65C Black is a durable black SLA resin formulated to meet the rigorous demands of high-performance 3D printing. It combines toughness, thermal stability, and visual quality—making it ideal for both prototyping and end-use production. With a heat deflection temperature of 70°C at 0.455 MPa, it withstands elevated temperatures without warping or deformation. This resin supports a broad range of industrial applications where thermal and mechanical durability are critical.
The high tensile strength of 41 MPa, along with its 35% elongation at break, makes it an excellent choice for parts that need to endure both impact and stress. Whether you’re developing snap-fit 3D parts, housing covers, or light mechanical assemblies, this 3D printing resin delivers consistent performance. Moreover, the deep black color and smooth surface give it an appearance similar to injection-molded parts, reducing finishing time.
Engineers often need materials that combine flexibility with toughness. Figure 4 Tough 65C Black hits that mark. It is engineered for high-impact 3D printing, offering resilience without brittleness. Its 6.6% elongation at yield allows it to handle repeatable flexing, which is essential for producing snap-fit 3D parts such as clips, tabs, enclosures, and sliding mechanisms.
This tough SLA material maintains dimensional accuracy across multiple print jobs. As a result, designers can confidently create interlocking or movable components without adjusting print parameters. Its isotropic strength ensures your parts function the same way regardless of orientation on the build platform.
Figure 4 Tough 65C Black is more than just a durable 3D resin—it’s designed for lasting performance. Tested under ASTM standards, it holds up to 8 years indoors and 1.5 years outdoors without significant degradation. That makes it a reliable choice for real-world, end-use 3D parts in sectors such as automotive, electronics, and consumer products.
In addition, this black SLA resin supports sterilization and meets UL94 HB flammability requirements. This expands its utility into environments that demand hygiene and fire safety. It also requires no secondary thermal cure, saving time in post-processing.
For professionals seeking a balance of toughness, flexibility, and quality, Figure 4 Tough 65C Black is a proven solution. It’s a truly durable black SLA resin optimized for high-performance, high-impact parts that need to last.
