New materials for SLS 3D printing
Only a small selection of materials based on thermoplastic polymers is currently available for the SLS process.
TIGITAL® 3D Materials are joining the game: Our thermosets offer you a completely new and innovative thermoset powder system for SLS 3D printing.
Special features and advantages of thermoset materials
- Excellent dimensional stability at high temperatures
- Excellent chemical and corrosion resistance
- High stiffness and modulus
- Excellent electrical insulation
- Higher productivity thanks to low-temperature printing (55 to 75°C), which reduces the heating and cooling phases
- Reduced capital investment needed for the 3D printer, due to the low printing temperatures
- Customer-specific adjustments of the color, chemical, thermal, and mechanical characteristics of our thermoset materials
- Economic development and production options from a few kilos to high-volume products
- Innovative technical properties
Under the brand name Chematronix®, we offer a complete solution uniting the fields of chemistry and mechatronics. We are collaborating to bring together the best of these two fields under one roof – for 3D printing results of the highest quality.
3D printing – also called additive manufacturing – enables the direct production from electronic data of three-dimensional polymer objects that were previously designed in the form of CAD drawings on a PC. There are no limits to their design and construction, because the components are built layer by layer in the printer without forming tools.
Additive manufacturing is particularly suitable for the industrial production of prototypes, as well as functional components in small batches. This makes 3D printing the optimal addition to conventional production processes such as injection molding or milling.
Selective laser sintering (SLS) is one of the most common 3D printing processes used in industrial additive manufacturing. A thin layer of polymer powder (100 μm) is applied with a roller in the printer's assembly space. Then a CO2 laser draws an exact 2D image of the CAD drawing on the powder and melts or sinters it in the places where the laser is directed. The cycle starts again with the placement of the next polymer powder layer, and is repeated until the necessary number of powder layers has been reached and the electronically designed 3D component is completed.
