...and dozens more innovative features!

Materials development is the new technology frontier in 3D printing. Many of the world’s top chemical engineers are racing to develop the thermoplastics of tomorrow. But many new, innovative materials already exist. With the Open Materials platform on 3ntr Printers, you are free to explore and develop superior solutions.

Or stay with the tried and true. We’ve done the research and established Material Profiles for dozens of materials, with more added all the time. We’ll give you advice for getting the best results, including the type of Support Materials that will work best.

ABS & ASA

You will love the results you get when printing these standards of the industry. You are free to use your own sources for the material, but we also offer formulations especially made for 3D printers.

Support Material

With the 3ntr, you can have a different support material and build material. Choices include break-away and soluble material that complement the build material. Your part finishes and delicate features will come out beautifully.

Design For Additive (like never before)

Your imagination gets a boost from the multi-material capability of 3ntr printers. The part shown here is the result of combining formerly separate parts to achieve a single design, integrating a hose and filter housing.

Combine Materials for Lower Cost

The part shown here was made with a combination of two different build materials. For the internal shaft, IGUS Iglidur is used for self-lubricating and hardness. To minimize the part expense, the body is made of ASA.

Rubber-like Materials

The controlled build chamber and powerful software enables you to make soft, rubber-like components.

Multiple Colors

You can print in two colors simultaneously.

Large & Complex

This part requires the precision of an industrial grade 3D printer. Soluble support material was used to preserve the precision of the delicate features.

Material Performance Enhancing Safety, Storage & Measurement Solution

Introducing the Material Management System (MMS) for optimized material handling with integrated HEPA and volatile organic compound health protection. The MMS keeps material dry for optimized bonding, performance and the best possible surface finish.

The automated weighing and reporting system provides you with real-time remaining material status for up to six spools at a time (from 4kg to 500g spools), any three of which are fed to the printer.

The MMS also manages power, requiring only one 220V connection for the cabinet which supplies the correct power and voltage to the printer, the print server and the web camera.

The MMS system includes an industrial, fanless print server with the power to support live video streaming of HD quality print monitoring, and increases storage from 16GB SD card standard with the printer to 128GB SSD for time-lapse recordings, virtually unlimited gcode storage and increased robustness.

The MMS features chamber heating (40°C), a powerful desiccant drying solution, integrated HEPA filtration with activated charcoal stage to control VOCs, increased connectivity options and a 10″ wireless screen control.

Enabling industry-leading safety, print quality, part size capability and user convenience, 3ntr printers with the MMS offer the best, most cost effective open material industrial additive manufacturing solutions available.
