All materials comply with ISO 9001/13485 and FDA standards for medical, food-safe, and aerospace applications. Certificates are available upon request. Need a specific compliance? Contact our quality team.  

Absolutely. We specialize in engineering-grade materials like PEEK (FDM), carbon fiber composites (FGF), and aluminum alloys (SLM). These materials withstand extreme temperatures, chemicals, and mechanical loads, ideal for aerospace, automotive, and industrial tooling.  

Yes! We support sustainable 3D printing with biodegradable PLA, recycled PETG, and upcycled nylon powder (SLS/MJF). Our processes minimize waste, and unused metal powders are reused. Request an “eco-audit” to reduce your project’s carbon footprint.  

Select materials based on strength, temperature resistance, flexibility, and budget. For functional prototypes, use ABS or nylon; metal alloys (SLM) suit high-stress parts, while resin (SLA) offers smooth finishes. Our team provides free material recommendations via instant quotes. Share your project goals for tailored advice!  

At OLA, we provide 30+ materials for metal, plastic, and resin 3D printing, including titanium (SLM), nylon (SLS/MJF), photopolymers (SLA/DLP/LCD), and engineering-grade options like PEEK and carbon fiber composites (FDM/FGF). Our  eco-friendly range includes biodegradable PLA and recycled nylon. All materials meet ISO/FDA certifications for aerospace, medical, and industrial applications.

Design Prototypes

Design prototypes are created to evaluate aesthetic and ergonomic features. They serve three key purposes:  

1. Facilitating detailed design studies, including spatial representation, proportions, aesthetics, haptics, and technical functionality.  

2. Acting as presentation models for decision-making or customer approval.  

3. Providing the foundation for generating 3D data required for design and production.  



Functional Prototypes

Functional prototypes demonstrate the essential performance characteristics of a final production component. These prototypes verify mechanical, electrical, acoustic, or thermal properties to ensure functionality.  



Geometric Prototypes

Geometric prototypes are precision models designed for initial assembly and user testing. They focus on verifying form, fit accuracy, and tolerances, with less emphasis on material-specific properties.  



Concept Prototypes

Concept prototypes are created to visualize a particular idea or explore innovative concepts during the development process.
