SLA Technology

SLA (Stereolithography) is a cutting-edge 3D printing technology that uses a UV laser to cure liquid resin into highly detailed and precise solid parts. Known for its ability to create smooth, accurate, and complex designs, SLA is widely used across industries for a variety of applications, from prototyping to final-use parts.

Applications

High-Temperature

  • Aerospace Components: Ideal for producing high-detail, heat-resistant parts used in aerospace applications.
  • Automotive Parts: Suitable for automotive parts that must endure high temperatures, such as under-the-hood components.
  • High-Temperature Fluid Flow Analysis: Perfect for creating prototypes and testing models that need to withstand heat during fluid flow analysis.
  • Functional Prototypes: Excellent for functional prototypes requiring resistance to heat and humidity for testing in real-world conditions.
  • Low-Volume Connectors & Harnesses: Ideal for producing low-volume electronics components, such as connectors and harnesses, that need heat tolerance and durability.

Advantages:

  • High Heat and Humidity Resistance: Ensures parts perform reliably in high-temperature and moisture-laden environments, making it ideal for both automotive and aerospace uses.
  • Exceptional Durability: Strong and stable, ProtoTherm™ 12120 is built to withstand physical stress and environmental challenges.
  • Smooth Finish: Produces parts with a superior surface finish, reducing post-processing needs and enhancing aesthetic quality.
  • Precise Detail: Offers excellent dimensional stability, allowing for the production of complex, highly detailed parts with consistent accuracy.

Disadvantages:

  • Limited Color Option: Available only in red, which may limit aesthetic flexibility for certain applications requiring different colors.
  • Higher Cost: As a specialized high-temperature material, ProtoTherm™ 12120 may be more costly than general-purpose SLA resins, impacting project budgets for large-scale production.
  • Requires Specialized Printers: Only compatible with specific large-frame SLA printers, which may limit accessibility depending on the equipment available.
