CAD-Ray · Chairside speed-sintering furnace
CAD-Ray CS Chairside Zirconia & e.max Furnace
The CAD-Ray CS is a compact, fast chairside furnace that sinters a zirconia crown in under 20 minutes (18.5 minutes with Katana STML) and crystallizes e.max in 14–22 minutes. Built on the Shenpaz SINTRA CS platform and finished in black with CAD-Ray CS branding, it brings same-day zirconia into the practice.

Key features
Same-day zirconia
Fast cycles sinter a single crown in under 20 minutes, so you can mill, sinter and seat in one visit.
Zirconia and e.max
One furnace for speed-sintering zirconia and crystallizing lithium disilicate.
Extra-wide 70 mm table
Fits 5 individual crowns or a bridge of up to 7 units per cycle, with up to 3 stackable trays.
Open, programmable system
Unlimited programmable heating, cooling and holding stages, ready for today’s zirconias and future materials.
7″ touch screen
A full-touch LCD with an interactive graph of every multi-stage program and the elapsed cycle time.
Compact footprint
About 313 × 375 mm, so it fits next to the mill in a small lab or operatory.
Indications
- Fast-sintering zirconia crowns and short bridges (e.g. Katana STML)
- e.max / lithium disilicate crystallization
- Same-day single-visit restorations
- Small-batch chairside production
