Stratasys’ MakerBot has added three newly-qualified 3D printing materials from Lehvoss for engineering applications that require high strength and heat resistance.
According to MakerBot, the Luvocom 3F materials will be integrated into its ‘Method’ 3D printing platform – the only 3D printer in its price class with a heated chamber that can print composites, polymers, and metals – all on one machine.
The addition of the new materials brings the number of Method materials to 30, giving MakerBot’s customers an even wider selection of manufacturing-grade materials to explore from.
The Luvocom 3F materials have similar properties to their compounded versions used for injection molding, says Lehvoss, a leading provider of high-performance thermoplastics for industrial sectors.
These materials are specially optimized to provide an easy-to-print experience and to achieve the next level of properties and quality.
According to Lehvoss, parts printed with these materials result in strong, stiff prints with a high-quality surface finish, and are ideal for prototyping, jigs and fixtures, and end-use applications.
MakerBot says that the Luvocom 3F PAHT 9825 NT, Luvocom 3F PAHT CF 9891 BK, and the Luvocom 3F PET CF 9780 BK will be available to use with the MakerBot LABS GEN 2 Experimental Extruder for both the Method and Method X 3D printers.
The Luvocom 3F PAHT 9825 NT is a high-temperature polyamide (nylon) material with continuous service temperature of up to 100°C and the strength of PA/Nylon 6.
The material has 50% reduced water uptake and a four-times slower absorption rate compared to PA6. Low moisture absorption can help minimize printing issues as well as property changes of the printed part.
According to Lehvoss, this material is optimized for low warpage, high strength and impact resistance, and excellent surface finish for end-use parts, such as flanges and fixtures.
Luvocom 3F PAHT CF 9891 BK on the other hand has an even lower water uptake and good resistance against harsh chemicals like automotive fluids on account of being carbon fiber-based (CF).
The addition of CF strengthens the thermal and mechanical properties, and has a continued use of up to 150°C while retaining 50% of its mechanical properties.
This makes it suitable for for high temperature environments such as automotive under-the-hood applications, such as housings or engine covers.
The Luvocom 3F PET CF 9780 BK is a carbon fiber-filled polyethylene terephthalate (PET) material that is easy to print.
It offers low warping, and exhibits a superb surface finish straight from the printer, reducing the need for post-processing.
What’s more, it provides high strength, elevated temperature resistance up to 120°C and chemical resistance outperforming PETG.
