Beyond the hype surrounding 3D printing are the realities of physics and chemistry. With the A2 and A4 from 3ntr you will master those realities to achieve prototypes that stand up to field testing as well as long lasting end-use parts.
Build Chamber
- Generous capacity for parts up to 23″ x 13″ x 19″ (depending on configuration)
- Individually controlled heating elements to achieve optimal accuracy and finish from the material you use
- Nozzle up to 806° F (430° C)
- Bed up to 320° F (160° C)
- Chamber to 194° F (90° C)
- HEPA filtered air flow to limit contamination
Printer Bed
- Reusable bed for thousands of prints with minimal maintenance
- Optional PEI Diamond Tray
3 Extruders
- One extruder for support material
- Two extruders for build material
- Allows combinations of materials on a single build
- Liquid cooling at each extruder for precise temperature control
- Unprecedented freedom in design
- Tungsten Carbide Bliss nozzles (optional)
Integrated Camera & Web Monitoring
- Monitor the build process from another location
- Make remote adjustments through the web interface
The World's Best Material Management System (optional)
- Protect your expensive spooled material
- UV-free
- Low humidity
- Real-time monitor displays material usage and amount remaining
- Holds up to six actively mounted spools
- Feed into the printer, keeping the spool protected
- Doubles as printer base
Powerful, Flexible User Interface
KISSlicer is powerful software that prepares STL files for optimized printing. The user interface enables you to select preloaded settings or to adjust dozens of variables yourself.
- Adaptive Layer Control — enables you to optimize layers
- Preload — precise control of how the printer extrudes filament
- Expert Mode — enables you to precisely set variables for your own unique configurations
- Fractional Number of Loops — improves bonding between loops and infill
- Lock Paths — lets you configure different styles for different parts on a single print
- Wizards — guides the processes of setting up Profiles and Tuning the material flow
- Object Packer — to maximize the output on the build table
...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.
