Compounds for extrusion-based 3D printing processes
The Hamburg-based German company Lehmann&Voss&Co. KG (LuV) is showcasing the new product line Luvocom 3F for 3D printing at Fakuma 2017. The materials are optimised for use in extrusion-based 3D printing processes – including fused filament fabrication. Support for the development comes from the company’s own pilot plant for 3D printing.
In addition, the company is presenting the new Luvocom CXR product line comprising of thermoplastic compounds based on polyamide that can be crosslinked by irradiation. Products from this line are characterized by an elevated temperature resistance and continuous service temperature, the company said. Combining them with reinforcing materials and additives makes it possible to produce high-strength and tribologically enhanced compounds. According to LuV, this leads to higher material strengths under the influence of heat together with a longer lifespan of components.
Based on the high-temperature resistant polymer PEEK, Luvocom 1114 offers new materials with exceptional tribological and thermal properties. In comparison to other high-temperature polymers, the wear and friction characteristics of compounds from this line exhibit a low and uniform curve up to 165 °C. Luvocom 1114 also has an elevated heat deflection temperature.
Furthermore, the company is presenting the new Luvobatch PA BA 1001/1002 blowing agent system, which can reduce the weight of polyamides with reinforcing materials such as glass fibres, carbon fibres and minerals by up to 30 % and simultaneously maintain the loss of mechanical properties at a low level. As an example, foamed components produced with this system exhibited a performance factor for bending stress in the range from 1 to 1.3, said LuV. Consequently, the change in flexural strength is smaller than the reduction in weight.
