SLA – Accura ClearVue
Accura ClearVue is a high-performance, transparent 3D printing material designed for use in Stereolithography (SLA) technology. It is widely used in applications that require clarity, visual appeal, and durable mechanical properties. Accura ClearVue is especially valued for its optical clarity, making it ideal for parts that need to simulate glass or clear plastics.
Key Material Facts:
- Great for models and prototypes requiring part clarity
- Functional end-use prototypes
- Thermoplastic-like performance, look and feel
- Beautiful transparent parts
- Parts can be printed solid and air / fluid tight right off the printer, no sealing required
- Humidity resistance is very high
- Compatible with assembly features including:
- Glue Joints / light welding
- Printed In Threads (However Helicoils are recommended)
Common Applications:
- Lighting and lenses
- Fluid flow visualization models
- Transparent assemblies
- Packaging/bottles
- Medical models and devices (USP Class VI capable)
- Prototypes of conformal cooling molds
- Models requiring high clarity
- Headlamps, Windows, IR Lens
- Medical Models and Medical Devices

Finish / Color Options:
Clear – Level 0 Strip & Ship – Excess resin is cleaned off the parts and supports are removed. Support surfaces are not sanded and are left rough. Part is transparent but layer lines are visible and looking through the part will be blurry.
Clear – Level 1 Bead Blast– Support surfaces are sanded. Bead blast applied to entire part for uniform finish. Parts have a smoked appearance like a milk jug.
Clear – Level 2 Rough Coat– Rough support areas are sanded smooth and the part is clear coated, layer lines will be visible in the clear coat but you can easily see through the part and make out details on the other side.
Clear – Level 3 Optical Coat – Layer lines removed from the entire part by hand sanding, Part is then clear coated and its as close to being optically clear* as is possible.
