Carbon 3D Resins
Industrial Resin 3D Printing Service: Carbon® High-Performance Polymers
Explore the capabilities of Carbon functional 3D printing resins: high-performance materials for professional applications.
Carbon 3D resins represent some of the most advanced solutions available today for engineers and designers seeking precision, reliability, and superior performance in additive manufacturing. Leveraging innovative materials and cutting-edge technology like Digital Light Synthesis (DLS), these resins deliver exceptional mechanical properties, high thermal and chemical resistance, and remarkable design flexibility for a wide range of applications.
Carbon offers a broad portfolio of rigid and elastomeric resins, suitable for multiple industrial sectors: automotive, consumer electronics, medical devices, and structural components. These resins are known for durability, ductility, and adaptability to complex geometries, while consistently maintaining high-quality standards.
Rigid and Epoxy Resins for Complex Structural Projects
Among Carbon’s rigid functional resins, key materials include:
EPX 82 (DLS): Designed for excellent toughness and long-term durability, even in demanding environments. Ideal for functional prototypes and structural components.
EPX 86FR: Flame-retardant, robust, and dimensionally stable, especially suitable for electronics and transportation applications.
EPX 150 (DLS): Excels in heat and chemical resistance, perfect for high-stress components.
LOCTITE® 3D IND405: Transparent, rigid, and durable, frequently used for functional aesthetic applications.
RPU 70 & RPU 130 (DLS): Offer a combination of strength and ductility, capable of withstanding impacts and deformations.
Carbon Polyurethane Resins: Flexibility, Durability, and Energy Return
Carbon’s elastomeric resins combine flexibility, tear resistance, and dynamic performance, making them ideal for high-impact applications or parts that require comfort and energy return. Polyurethane resins provide durability and precision even in complex geometries.
Key elastomeric materials include:
EPU 40 & EPU 41 (DLS): High-performance elastomers with excellent energy return and fatigue resistance. Ideal for technical footwear, protective devices, and ergonomic coatings.
EPU 43 (DLS): Soft, durable, and impact-absorbing, suitable for applications requiring flexibility and long-term performance.
EPU 45 (DLS): Developed for shock-absorbing applications, such as padding and protective equipment. Provides outstanding mechanical energy absorption during repeated impacts while maintaining elasticity.
EPU 46 (DLS): Engineered for applications requiring high energy return, such as soles and sports components. Offers adjustable stiffness, color customization, and excellent dynamic performance. Perfect for lattice structures and custom designs.
These resins expand 3D printing capabilities, allowing designers and engineers to create functional, durable products with optimized mechanical performance, tailored to project requirements.

Key Benefits of Carbon 3D Resins
Durability and Strength: Carbon Rigid resins like RPU 70 withstand mechanical and environmental stress, providing an ideal balance of robustness and lightweight performance. Suitable for functional prototypes, electronic housings, and structural parts.
Fast, Efficient Production: Carbon’s DLS technology enables high-volume production in shorter timeframes, ensuring consistent quality and customized components.
Flexibility and Customization: Elastomers such as EPU 46 provide high energy return and shock absorption. Variable-density lattice structures allow complex geometries, adjustable stiffness, and versatile designs—perfect for footwear, padding, and ergonomic components.
High-Performance 3D Printing Polymers for Industrial Applications
Carbon 3D resins represent the most advanced category of 3D printing polymers available for industrial and professional use.
Unlike standard FDM filaments, Carbon’s polymer-based resins processed through Digital Light Synthesis™ (DLS™) deliver isotropic mechanical properties, meaning parts perform consistently in every direction — a critical requirement for functional end-use components.
From rigid epoxy-based polymers like EPX 82 to flexible polyurethane formulations like EPU 46, Prototek offers the full spectrum of high-performance 3D printing polymers to meet the demands of automotive, electronics, robotics, and medical device manufacturing.
Epoxy Resin 3D Printing: Structural Performance for Demanding Applications
When engineering requirements demand the highest levels of rigidity, thermal resistance, and long-term dimensional stability, epoxy resin 3D printing through Carbon’s DLS technology is the definitive solution. Prototek’s epoxy resin 3D printing service leverages Carbon’s EPX series — EPX 82, EPX 86FR, and EPX 150 — materials specifically engineered for functional end-use parts that must perform reliably under mechanical stress, elevated temperatures, and chemical exposure.
3D printed epoxy resin components produced via DLS outperform traditionally manufactured counterparts in several key areas: isotropic mechanical properties ensure consistent strength regardless of build orientation, while the layer-free surface finish eliminates the weak points typical of FDM or SLA-based epoxy 3D printing processes. EPX 86FR adds flame-retardant certification, making it the preferred choice for electronics enclosures and transportation components subject to safety standards.
Industries that benefit most from Prototek’s epoxy resin 3D printing capabilities include:
- Automotive: heat-resistant housings, brackets, and under-hood components
- Electronics: rigid, flame-retardant enclosures with tight dimensional tolerances
- Industrial manufacturing: functional jigs, fixtures, and tooling components
- Aerospace and defense: lightweight structural parts with certified material traceability

Polyurethane & Rubber Resin for 3D Printing: Soft Elastomeric Materials
When your project requires a 3D print soft material that combines flexibility, tear resistance, and long-term durability, Carbon’s elastomeric portfolio is the industry benchmark. Carbon’s EPU series defines the state of the art in polyurethane 3D printing, offering formulations that combine the mechanical behavior of cast polyurethane with the geometric freedom of additive manufacturing.
If you are looking for a reliable rubber resin for 3D printing, materials like EPU 45 and EPU 46 are engineered specifically as soft 3D printing materials capable of absorbing repeated mechanical stress without losing shape. 3D printed polyurethane parts produced via DLS™ technology exhibit exceptional fatigue resistance, high elongation at break, and predictable energy return — properties that are notoriously difficult to achieve with injection-molded TPU or traditional silicone casting.
Applications range from footwear midsoles and vibration dampeners to ergonomic grips, gaskets, and protective padding. If your design demands a flexible solution that holds up under real-world conditions, Prototek engineers can help you select the right EPU grade and design the lattice structure that maximizes performance while minimizing material usage.
Our service delivers results that traditional rubber manufacturing simply cannot match in terms of geometric complexity and lead time.
