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:

  • Sand molds
  • Mold cores
  • Investment casting patterns

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:

  • Fast printing: With a printing speed of 2. 5 inches per hour, foundries can create new casts ready for part production use in just a few hours.
  • Quick implementation: The entire printing system works out of the box. Once installed and calibrated, no further programming is required.
  • Improved productivity: Foundry workers don’t need to be trained on new machinery as the solution utilizes other machinery they already use. And, since the solution is entirely automated after set up, operators don’t need to intervene during the printing process as the printer automatically cleans the printer head, parks, prints, and refills the sand chamber.
  • Reduced material costs: RAM technology uses less sand than previous sand casting methods.
  • Increased cast strength: Casts have incredible strength of 175psi when ambient dried and 370psi when baked at 350°.
  • New production methods: Rather than having to create and ship casts around the world, organizations can simply ship the raw materials and transmit the casting files to their foundries for production.

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.

Sand Castings in Just A Few Hours

The Robotic Additive Manufacturing systems from EnvisionTEC and Viridis3D are the fastest, most flexible robotic 3D printing options in the foundry and 3D printing industries today.

The RAM 123 from EnvisionTEC and Viridis3D is the fastest, most flexible robotic 3D printing platform in the industry. Using a patent-pending technology, a proprietary print head attached to an ABB robot arm uses exclusive binder jetting technology to print sand molds and cores for the foundry industry. The proprietary system includes easy-to-use software that uses a CAD file to print a mold and core in just a few hours.

  • Description

Exclusive Binder Jetting Technology

Using a patent-pending technology, a proprietary print head attached to an ABB robot arm uses exclusive binder jetting technology to print sand molds, mold cores and investment casting patterns for foundry applications. The proprietary systems include easy-to-use Viriprint software that uses a CAD file to print a mold and core in just a few hours.

A variety of build envelopes are now offered. The RAM 123 prints pieces up to 1’ x 2’ x 3’, with a RAM 224 (2’ x 2’ x 4’), RAM 236 (2’ x 3’ x 6’), and RAM 336 (3’ x 3’ x 6’) now available. Viridis3D can also develop custom solutions with this scalable solution.

Foundries will appreciate the speed with which the systems prints — and how fast their operation can be up and running with the new technology. What’s more, the RAM systems use less sand and are substantially less expensive than other sand casting 3D printers on the market today. In fact, the Viridis3D systems use about one-third the cost of competing technologies that build in a box.

This disruptive technology brings a new way of production to foundries — instead of shipping castings around the world, raw materials are shipped and files are simply transmitted to 3D printers in strategic locations. The result is castings are poured the same day, only where you need them.

EnvisionTEC and Viridis 3D turn industrial robots into 3D mold printers

News

EnvisionTEC GmbH is mainly known for its proprietary professional-grade photopolymer 3D printers, widely used in jewelry and dentistry, but recently the German manufacturer has also been developing additive systems for the production of molds.

The work is carried out jointly with the American company Viridis 3D.

Viridis 3D engineers set out to develop a versatile 3D printing system that can be easily adapted to the needs of individual foundries. Robotic manipulators produced by the Swedish-Swiss company ABB were chosen as the positioning mechanism. Special arrays of several heads are hung on the robotic arm, applying a binding agent to the layers of sand.

The system is designed for the production of molds and cores from quartz sand, and as binders, modified furan resins used in the production of polymer concrete, in combination with solid acid catalysts, are used. Different system options are available with different sizes of nozzles - 28" wide arrays with twelve heads or 38" arrays with sixteen heads. The 3D printer is controlled by Viriprint's proprietary software, which allows printing from CAD models.

The construction area depends on the version: 305x610x915 mm in the RAM 123 version, 610x610x1220 mm for the RAM 224, 610x915x1830 mm in the RAM 236 version or 915x915x1830 mm in the RAM 336 version. axes. The performance of the systems is quite high: the growth rate reaches 65 mm/h. The printed products are fired at a temperature of 175°C, after which the strength reaches 2.55 MPa.

In addition to high productivity and production flexibility, Viridis 3D 3D printing systems are also highly cost-effective. The cost of equipment is relatively low when compared with stationary systems of similar capabilities, such as Voxeljet 3D printers. Compared to traditional methods of making molds, 3D printers reduce sand consumption and time costs: the full production cycle from a digital model to a molded product takes a couple of days instead of two months. Additional information is available on the EnvisionTEC website.
