EnvisionTEC Viridis 3D Printer: Create Custom Castings for Metal Foundries

The EnvisionTEC Viridis 3D printer is an additive manufacturing system that utilizes Robotics Additive Manufacturing (RAM) technology to create custom castings in a matter of hours. The printer uses a proprietary print head attached to an ABB robotic arm to quickly create:

The EnvisionTEC Viridis 3D printer cuts down on the costs and time associated with creating castings compared to traditional methods. The printer is 1/3 the price of other print casting machines and complete part production time is reduced from 8-10 weeks to just 2-3 days.

The EnvisionTEC Viridis 3D Printer costs 66% LESS than other casting machines and allows foundries to begin producing custom parts in just 2-3 days.

Benefits

This custom casting 3D printer provides metal foundries with numerous benefits including:

How it Works

Software Process

  1. Launch and upload STL files into the Viriprint program.
  2. Users can set up, scale, orient, and justify the build volume of their print.
  3. Save print setup and orientation settings for easy repeat prints or to share settings with other foundries.
  4. Begin print job.

Printing Process

  1. Sandhopper delivery system fills the printer head from the backside with sand (solid consumable).
  2. ABB robotic arm positions the print head over the table.
  3. The Viridis 3D printing head drops, spreads, and prints the sand and binder jetting fluid.
  4. CAD software guides the arm, raising the height to complete the printing process layer by layer until the mold is complete.

Assistance in Challenging Times

At 3 HTi, we understand that all manufacturing industries are affected by the COVID-19 outbreak, and one area that is hit harder is technical training and support. For industrial manufacturers and other hands-on industries, the close contact required for training and support activity is no longer an option due to quarantining and social distancing to reduce spread of COVID-19.

In an effort to assist our customers and reduce business disruptions during this critical time, 3 HTi is offering Vuforia Chalk at no cost for a limited time and 2 hours of Remote Distance Coaching per Creo License.

Vuforia Chalk is a remote assistance app that uses augmented reality for knowledge transfer between a technician and a remote expert. The powerful remote presence experience of Vuforia Chalk combines live video, audio and the ability for both the remote and local participant to annotate a live shared view. Annotations in Chalk accurately stick to real-world objects, even when people move around, utilizing advanced augmented reality and marker-less computer vision technologies developed on the best-in-class Vuforia AR platform.  To learn more about Vuforia Chalk, visit our webpage.

Remote Distance Coaching will be provided to 3 HTi customers for 2 hours for each license of Creo.  If you have 3 licenses of Creo, you would get 6 hours of Coaching.  This can assist your CAD users whether they are working in your office, or remotely at home.

Creo Home Use License – All subscriptions of Creo include a home use license.  Let us know of you need any assistance accessing the home use license for Creo.

Click here to contact us, and we will assist you with either program.  We sincerely hope you and your family are safe and healthy!
