Case Studies SDS

EnvisionTEC’s E-Denstone Material was developed for dental model manufacturing. The matte finish allows models to be scanned accurately for verification purposes and the high viscosity of the formula produces superior details and surface finish. The biggest advantage is its build time – a staggering one inch in under 90 minutes at 35 micron resolution in Z. It can be used with traditional dental manufacturing methods or as a CAD based model solution. This is the only material that allows you to easily die trim, margin mark with a red pencil and hand wax to the die without concerns for layer lines. Die paint sticks to the dies just like plaster and won’t peel off. The material looks and feels like traditional gypsum models, which sets it above the other resinbased models currently on the market. The low viscosity formula combined with high accuracy printers helps to produce superior results with no loss of anatomy detail.

E-Denstone Tough is strong enough for a dental technician to repeatedly remove and replace the die, check occlusion and move through excursions without any loss of fit or causing excessive wear on the contact surfaces. The cleanup does not use messy oils or heat that can cause distortion and takes only 3 minutes. The biggest advantage is its build time – a staggering average build time of under 2.5 hours with a full platform of crown and bridge models. All this with 35 micron resolution in Z. This means the lab is able to complete several builds in an 8 hour shift, allowing for fast turnaround of highly detailed accurate models. Unattended production means the machine can work while you are away. It will even turn itself off after completing a build.
