UMA 90 Resin for Prototypes — Rigid, Affordable, and Fast (Carbon DLS)
UMA 90 Carbon DLS: If you’re looking for a rigid and cost-effective resin for 3D printed prototypes, this is an excellent choice for rapid design validation and functional testing.
This single-component resin is specifically designed for rapid prototyping using Carbon’s Digital Light Synthesis (DLS) technology, combining high printing speed, ease of use, and a smooth surface finish.
UMA 90 is ideal for jigs, fixtures, visual models, and low-stress parts, where performance, speed, and cost efficiency matter most.
What Is UMA 90?
UMA 90 (Urethane Methacrylate) is a rigid, one-part photopolymer resin developed by Carbon for the DLS 3D printing platform. It delivers consistent quality for visual and functional prototypes that don’t require high mechanical performance but demand excellent surface finish and dimensional accuracy.
Available in a white base color, UMA 90 can also be custom-tinted in shades such as black, gray, cyan, magenta, or yellow—or mixed to match your preferred tone. This flexibility makes it perfect for teams needing aesthetic prototypes that closely resemble final parts before moving to production materials.
Key Benefits of UMA 90 Resin
Rigid, single-component resin: simple handling and no need for two-part mixing.
Affordable for rapid prototyping: ideal for design validation without over-engineering costs.
Compatible with Carbon DLS printers: optimized for M-series systems for precision and consistency.
Custom color options: mixable pigments allow a wide range of visual effects.
Fast printing & iteration: it accelerates concept testing, fit checks, and prototype validation.
Excellent surface finish: this resin produces smooth, detailed parts ready for visual evaluation or light use
Key Features
- Naturally white base; can be printed in different colors upon request.
- “Simple” resin (single-component) printed using the Carbon M2 system.
- Cost-effective.
- Suitable for producing prototypes that do not require high performance.
- Good surface finish.
Why Choose a Rigid Resin for Prototyping?
When validating a design, engineers often need stiff, accurate prototypes that simulate real-world behavior.
UMA 90 Carbon DLS provides high rigidity and stability, making it perfect for form-fit-function testing, assembly validation, and ergonomic studies.
Compared to flexible or high-performance engineering resins, UMA 90 offers shorter print times, simpler post-processing, and lower cost per part, without sacrificing quality where it counts.
It’s the ideal solution when you need to:
Verify geometry or assembly tolerances
Test part fitting or mechanical clearances
Evaluate visual appearance before final production
Create fixtures, jigs, or inspection tools for low-load environments
Typical Applications
Design validation prototypes — test form, fit, and function early in development
Visual models — present accurate, high-quality parts to clients or stakeholders
Jigs and fixtures — create functional tools and assembly aids with short lead times
Masks and templates — produce rigid parts for production or finishing operations
Cable clips, housings, or small components — ideal for rapid iteration and visual testing
UMA 90’s fast print times and easy handling make it a great choice for design teams that value speed, simplicity, and repeatability in their prototyping workflow.
UMA 90 vs Other Carbon DLS Resins
Carbon offers a range of DLS materials—from elastomeric EPU series to rigid RPU or FPU grades.
UMA 90 sits at the entry point of the rigid resin family, balancing printability, speed, and affordability.
| Property | UMA 90 | RPU 70 | EPU 41 |
|---|---|---|---|
| Rigidity | High | Medium-High | Low (flexible) |
| Cost | 💰 Low | 💰💰 | 💰💰💰 |
| Surface Finish | Excellent | Good | Moderate |
| Recommended Use | Prototypes, jigs, fixtures | Functional parts | Elastomeric components |
That’s why UMA 90 is often chosen for early-stage design, when the goal is to test shape, fit, and visual quality before moving to stronger or more complex resins.
