What We do?
Technology
infrar3D has developed a novel laser preheating technology which makes FDM machines capable of producing components with more than double the tensile strength in comparison to conventional 3D-printers.
Why infrar3D
infrar3D specialties
Highest Safety Standards
Unique Technology Made by German Engineering
Suitable for industrial Environment with highest Requirements
Top Efficiency through Reinventing Ourselves every single day
What's new?
Innovation
3D printing processes work in layers
-> Adhesion of layers
-> Splices are weak points
Reduced intra-layer tensile strength towards inner-layer
-> Components tend to fail
Limited application of FDM process in industry
How can we increase inter-layer tensile strength on an industrial scale?

infrar3D’s Novel Laser Preheating Technology
What distinguishes infrar3D laser preheating from conventional FDM printers and other preheating developments?
Stronger Parts
- Additional thermal energy creates an extended time period for polymer chain diffusion across interface
- Increased bonding of layers
- Higher tensile strength in Z-direction (Build direction)
Independent of Direction
- During nozzle travel in any direction thermal laser energy is inserted into the part
- Every spot of component benefits from laser preheating
- Technology is first of its kind to be adequate for industrial use
Physically separated build chamber from laser and control unit
- Higher temperatures in build chamber are possible
- More variety of usable plastics such as ABS, PETG, PMMA, PC, etc.
- Reduced susceptibility to failure
- Increased maintenance possibilities, even during build process
- Adequate cooling of laser and control unit
- Change of filament during build process
- 24/7 use of machine
Safety First
- 100 % laser proof aluminum case with laser proof window and camera to observe in situ build process
- Safety circuit, when door is open, laser stops immediately
The team of infrar3D
The founding team of infrar3D has been working on the project since 2020 and is supported by the EXIST Founder Grant by German Government and European Union and the Jung Innovators program by Baden-Württemberg state ministry.
