The complete 3D filament printer system for orthodontic model fabrication

SIMPLEX 3D filament printer - simply plug and print

Printing orthodontics models – A simple and sustainable solution with SIMPLEX

With its unique advantages, the SIMPLEX 3D filament printer stands out from other filament printers. The SIMPLEX 3D filament printer system is a coordinated dental system solution in the filament printing segment (modified 3D filament printer, dental slicer software, and bio filaments for orthodontic model fabrication) for consistent reproduction and reliable results. The best thing about it: The printed models don’t need any post-processing.


The technology is as simple as it is ingenious: Filament printing (FDM/FFF process) uses fused filaments. These are thermoplastics in wire form assembled on a reel. The material softens under the influence of heat. A nozzle then builds up the 3D print object layer by layer on the print bed. Done!


The filaments used in the SIMPLEX 3D filament printer system are mainly bioplastics that can be recycled and industrially composted without the need for any complex processes. This gives you an environmentally sustainable way of creating a 3D-printed object.


Ecological, sustainable and health-friendly:  

  • 100% free of irritant substances
  • No polymerization in the light-curing unit necessary
  • No post-processing with chemicals required
  • Eco-friendly and health-friendly printing
  • Colorfast, UV-resistant

The SIMPLEX 3D filament printer system was developed to meet the specific requirements of orthodontic laboratories and offices. It is very simple to use: Whether in the orthodontic office or laboratory, the optimized material profiles offer a standardized application and thus simple and reliable operation without prior knowledge. For: all important printing parameters for the orthodontic field are already pre-installed. This makes getting started with 3D printing easy, intuitive and reliable.


Reproducible, reliable and easy

  • Pre-installed programs for the orthodontic sector and the specific models
  • Filament monitoring system with notification function and automated troubleshooting
  • Easy familiarization for the office and laboratory team

All three system components - the printer, the dental-specific slicer software and the appropriate filaments - are perfectly matched to each other and to the requirements in the orthodontic field. The result: consistently reproducible and reliable results.


Easy, effiefficient and reliable: 

  • Process reliability thanks to pre-set printing parameters 
  • Versatile print bed for maximum utilization
  • Extremely quiet printing process
  • Detailed results

What our customers say

‘‘The convenient "plug and print" absolutely convinced me. Renfert has really put its “making work easy” performance promise into this device. In a nutshell, that means: no major effort, no high investments, no environmental impact, and an automated, controllable, and valid process without time-consuming trial and error. I select the program, push the button, and the system does what it is supposed to – fantastic!‘‘

"We chose 3D filament printing, specifically the SIMPLEX 3D filament printing system, for a number of reasons. First and foremost, the process flow convinced me - we can avoid all the post-processing. And: whenever possible, I operate in an ecologically sustainable manner in my everyday work. For filament printing, bio-filaments can be used; thus, renewable resources are used."

"For me, the main argument for buying a filament printer was that no post-processing of the printed objects is necessary;. In addition, the work is more ecological; on the one hand because of the filaments themselves. On the other hand, fewer chemical substances are needed and there is no hazardous waste. Another important factor in the decision is health protection for us as a team, because the filaments do not emit any toxic fumes during the printing process."

‘‘The SIMPLEX 3D filament printer stands out thanks to its simplicity and intuitive operation. Theoretically, anyone in the team can operate the printer. And there are no chemicals and no post-processing (which is unavoidable with resin printing). This means no isopropanol and no light curing. This allows us to meet our objectives not only regarding environmental and climate protection but also regarding health protection within our office team.‘‘

“The software is very intuitive and with its preset programs it is a great support in positioning the virtual model and setting the printing parameters. The printed model is dimensionally precise and stable during the processing of aligners or thermoformed plates, but above all it has never fractured. Now when I receive a digital impression, I am much more relaxed because I know that I will produce accurate and reliable work. The dentists I work with have appreciated the result confirming that the plates are very stable and retentive.

Therefore I can say that Simplex really really stands for "Simplicity" !“

"Digitization is not the future, but the present. Dental offices should also invest in digital technologies. Intraoral scanners, CAD/CAM milling, 3D printing - many applications are implemented digitally. Various technologies are used for 3D printing, e.g. FDM or SLA. For model fabrication, we mainly use the SIMPLEX 3D printing system. Most popular features are speed and consistent product quality."

"Digital processes support cost-effectiveness in everyday orthodontic work. One example is model fabrication using 3D printing. Since the SIMPLEX 3D printer is easy to operate and does not require any post-processing, it is a real relief in everyday work. No long training period is required; printing is intuitive. And, of course, environmental and health protection are important arguments in favor of filament printing; for instance, no toxic fumes are released. When it comes to print quality, it's particularly convincing for orthodontic applications."

"In terms of accuracy and precision, filament printing offers optimum quality for orthodontic models.  I would also like to emphasize the simplicity and process reliability of the SIMPLEX 3D filament printing system. It does not require extensive training. Application errors are virtually eliminated thanks to automatic presettings. And as I would like to avoid processing biologically harmful materials - if possible - filament printing also has a clear advantage here. Among other things, there are bio-filaments. In addition, there is no need for post-processing with chemicals."
