At its JEC World 2025 booth, Lehvoss Group (Hamburg, Germany) will focus on material offerings related to flame retardancy and the launch of its new Luvoprint 3D printing material product line.
Applications in the transport sector often place high demands on the use of materials, such as ISO 45545 for flame protection in rail transport. Lehvoss presents various high-quality, flame-retardant solutions that meet these requirements, as well as ready-made materials for processing methods such as pultrusion, injection molding and 3D printing.
Among its offerings for thermoset industry applications such as pultrusion, SMC/BMC, CIPP, RTM, winding and others, Luvotrent products assist with their ability to increase fiber wetting, fillers and resin flow to optimize line speed and improving surface quality. According to Lehvoss, these solutions enable fast, precise and reliable production and ensure efficiency throughout the entire manufacturing process.
For example, Luvogard reportedly offers an effective solution for flame retardant applications. The liquid and transparent state helps in adjusting and dosing viscosity and supports the production of advanced materials with high flame retardancy. In addition, Luvatine products offer highly functional wetting and dispersing agents. These active ingredients improve the dispersion of pigments and fillers in resin systems.

On the other hand, Lehvoss' Luvoprint is a product line focused on high-performance materials for fused granulate production (FGF), a 3D printing process that uses granules instead of filaments or powders.
Luvoprint materials are designed for the manufacture of components, molds, devices and fixtures in a wide range of demanding applications, from materials for structural applications in ambient conditions to materials for molds for curing composites in autoclaves under high temperature and high pressure. The Luvoprint portfolio includes qualities based on:
- Eco PC/ABS: Optimum dimensional stability, high processability and low CO2 footprint
- Eco PA6: High impact resistance, increased abrasion and wear resistance, low carbon footprint
- Eco PPS: Flame retardant, high chemical resistance and low carbon footprint)
- PESU: Flame retardant, high mechanical strength, optimal thermal stability.
According to the company, Luvoprint materials were developed and optimized specifically for the printing process. The materials were subjected to extensive testing on common industrial printing machines. Performance data and printer settings are available from Lehvoss and partners. The Luvoprint product range is continually being expanded and additional qualities are subjected to intensive testing.
Since the transition from traditional manufacturing processes to 3D printing can be challenging, Lehvoss also offers support in this process, from material solution to final product, to ensure reproducibility and cost-effectiveness of 3D printing in series production.
