The milling machine for orthodontic applications

E3 is vhf®'s specialist for the processing of occlusal appliances. It helps dental professionals to automate the precision of trimming the occlusal appliances such as aligners, bite splints, grinding splints and other variants up to sports mouth guards.

E3. Automated production on a small footprint.

vhf E3 is a very compact milling machine that has been designed and engineered for cutting out the most diverse shapes of thermoformed splints such as aligners, bite splints, grinding splints and other variants up to sports mouthguards. It can be set up in almost any setup due to its complete freedom from compressed air. Its footprint is a few centimetres more than that of an A3 paper sheet but with an interior built with high-quality industrial components. E3 is a tool-free clamping system, the first vhf milling machine specifically designed for orthodontic applications, meant to eliminate manual labour and offer CNC-precision end-results.

E3. Cut Out Occlusal Appliances @ Low Production Costs

Fast, Reliable and Affordable process

No Manual Labour. 

vhf® E3 is the first machine for an automated cutting process of thermoformed splints, such as aligners, bite splints, grinding splints or sports mouthguards. Until now, this process was manually done.  Not anymore.

Aligner and Splint Production | Easier than Ever

Thanks to its compact size, the E3 doesn’t require compressed air connection, therefore, it offers great flexibility in terms of installation site. In addition, no other extraction system is required, as this German-engineered milling machine was designed with a practical collection tray for chips.

Machine Aligners in 45 to max. 60 Seconds

Despite its compact design, E3 offers you CNC production high-precision accuracy and speed. For example, an aligner can be milled out in less than 60 seconds (45” in average).

vhf’s E3 is a tool-free clamping system built to ease your work and save you time in your entire series of aligners production. Besides aligners, this machine is also recommended for all sorts of occlusal appliances such as bite splints, grinding splints and other splints, including sports mouth guards.

TRIMCAM 1.4 with Open Interface to Planning Software

TRIMCAM | Smart Software 

vhf’s E3 comes with TRIMCAM 1.4, an in-house developed software which automatically recognizes the trimline on which the occlusal appliance is milled out from the available planning data.

Updated Features

  • Batch Processing | Allows the data of all dental splints of a treatment to be loaded into the software in the order specified by the user to process them in an organized manner.
  • Automatic Labeling Function | This function is optional; it can be selected or deselected. When activated, the specified STL file name is automatically printed on the base of the 3D dental arch model so that the thermoformed aligners can be clearly assigned.
  • Up to 25% Faster Processing Time | The TRIMCAM software automatically recognizes the so-called trimline on which the occlusal appliance will later be milled out from the available planning data. The fixation of the workpiece in the E3 is done in one second: without any tools, the splint is simply clipped into the holder. An aligner, for example, is milled out in 45 to 60 seconds
  • Import of external trimlines — With this function, users can import trimlines from any software in PTS format.
