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.
