Rigid Polyurethane Resin - Carbon DLS
RPU 130 Rigid Polyurethane Resin for 3D Printing – Carbon DLS
RPU 130 is a premium rigid polyurethane resin developed by Carbon, specifically engineered for 3D printing using Digital Light Synthesis™ (DLS) technology.
It delivers exceptional mechanical robustness, superior thermal stability, and excellent surface quality, making it ideal for demanding technical and industrial applications.
This advanced resin is designed to support functional prototyping, end-use components, and small to medium production runs with minimal post-processing, offering reliability, precision, and durability in one package.
Key Performance & Mechanical Properties
RPU 130 distinguishes itself through strong mechanical and thermal characteristics:
Impact Resistance: 76 J/m — able to absorb significant shock loads
Heat Deflection Temperature (HDT): 119 °C — holds dimensional stability under elevated temperatures
Isotropy & Surface Finish: uniform properties in all orientations, with excellent dimensional accuracy and mirror-like surfaces
Mechanical Robustness: comparable to unfilled thermoplastics such as nylon or polypropylene
Bio-based Content: incorporates 30% Susterra® propanediol, reducing carbon footprint while maintaining performance
Environmental Durability: certified performance after prolonged exposure to heat and humidity (PV1200 standard).
Because of its mix of strength, stability, and environmental resistance, RPU 130 Carbon DLS is well suited for parts exposed to continuous thermal cycling or humid environments.
Typical Applications & Use Cases
RPU 130’s properties make it a strong candidate for various high-demand uses:
Pressure Rivets & Fasteners
Components like pressure rivets require impact resistance, dimensional stability, and a degree of toughness. RPU 130 rigid polyurethane resin delivers all these, even under cyclical stress or temperature changes.
Eyewear Frames & Hinges
For sunglasses, optical frames, and foldable parts, the balance of stiffness, toughness, and fine surface finish is critical. RPU 130 Carbon DLS meets these needs while enabling lightweight, precise designs.
Housings & Enclosures
Electronic device housing, protective shells, and instrument casings benefit from RPU 130’s mechanical strength, thermal resistance, and capacity to preserve shape over time.
Industrial & Consumer Equipment
From mechanical parts in devices to premium consumer goods, RPU 130 enables features like snap fits, living hinges, and thin walls without sacrificing durability.
With Carbon DLS technology, you can produce these complex geometries quickly, with high detail and minimal finishing work.
Advantages of choosing RPU 130 Carbon DLS
High Impact Durability: withstands repeated mechanical shocks without failure.
Thermal Stability: this rigid polyurethane resin maintains structure and performance in elevated temperature environments.
Excellent Dimensional Precision: ideal for tight tolerance components
Sustainable Material Content: partial bio-based (30%) formulation helps reduce environmental impact.
Chemical & Environmental Resistance: it performs reliably under heat, humidity, and ambient stress.
Outstanding Aesthetic Quality: minimal need for post-processing thanks to smooth finishes.
These advantages make RPU 130 a top choice when performance, reliability, and aesthetics all matter.
Material behavior under stress & conditions
Mechanical & Impact Behavior
RPU 130 Carbon DLS is engineered to resist abrupt forces and absorb energy without cracking. Its impact rating of 76 J/m sets it apart among resins used for structural parts.
Thermal & Environmental Stability
With 119 °C HDT, RPU 130 retains its mechanical integrity in high-temperature environments. Combined with its certification for long-term exposure to heat and humidity (PV1200), it’s reliable in harsh conditions.
Material Isotropy & Dimensional Accuracy
Because of isotropic behavior, parts printed in any orientation maintain consistent mechanical performance. Dimensional accuracy is critical in mechanical assemblies, and RPU 130 ensures tight tolerances.
Chemical & Environmental Resistance
The rigid polyurethane resin resists degradation from humidity, heat, and ambient stress cycles. Its partial bio-based nature also aligns with greener manufacturing trends.
