SLA – Accura 25

Accura 25 is a high-performance 3D printing resin designed for use with Stereolithography (SLA) technology. It is known for its excellent mechanical properties, high detail resolution, and versatility, making it suitable for a variety of industrial applications. Accura 25 is particularly valued for its strength, dimensional accuracy, and smooth surface finish, which makes it ideal for functional prototypes and end-use parts.

Key Material Facts:

• Look and feel of molded polypropylene
• Superior strength and durability
• Thermoplastic-like performance, look and feel
• Functional end-use prototypes
• Good for checking snap fit designs
• Excellent moisture resistance
• Parts can be printed solid and are air / fluid tight right off the printer, no sealing required
• Compatible with assembly features including:
  • Glue Joints/light welding
  • Printed In Threads (However Helicoils are recommended)

Common Applications:

• Concept and Marketing Models
• Functional Assemblies and Prototypes
• Packaging
• Sporting goods
• Bottles and containers
• Cowlings
• Lids
• Medical Devices
• Electronic enclosure porotype
• Cast urethane mold master
• Great for all plastic prototyping applications

Finish / Color Options:

Level 0 – Strip And Ship –  Excess material is cleaned off part, supports (if any are present) are removed. Support surfaces are not sanded and are left very rough.

Level 1 – Support Sanding – Excess material is cleaned off part, supports (if any are present) are removed. Rough support surfaces are sanded smooth.

• Unless specified this is the finish all parts we print are shipped with.

Level 2 – Matte Finish – Support surfaces are sanded, parts are lightly sanded in all rough areas. Bead blast applied to entire part for uniform finish.

Level 3 – Mold Master – Layer lines removed through sanding of entire part. Bead blast applied to entire part for uniform finish. Part can be used as a master for cast urethan tooling.

Level 4 – Paint Prep – Layer lines removed through sanding of entire part. Part is prepared for painting with primer.

Level 5 – Cerakote – Layer lines removed through sanding of entire part. Part is then sprayed with Cerakote.
