Worlds´ first 4D filament for standard printers - temperature resistant to 230 °C enhances the possibilities of standard 3D printers (FDM): With >>k-top<< - the new developed filament - prints are now temperature resistant up to 230 °C.
The material is suitable not only for building models and making things but also for industrial appliances such as small series, prototypes and tightly measured objects.The thermoplastic compound offers all new possibilities. Volker Bernhardt, CEO of >>Temperature resistant objects near motor compartments or hotends can be printed reliably now<<. As a big bonus, the new material is mechanically stronger than PLA or ABS. developed the new material for industrial customers and started a piloting campaign in partnership with a big automotive customizer. The campaign showed to be fully successful and now offers their new material >>k-top<< to home consumers. The material is suitable for all standard 3D-FDM-printers which can hold temperatures of 260 °C. A heated bed or a heated printing chamber aren´t necessary. >>k-top<< prints docile, accepts active cooling and owns a great inter-layer adhesion. After printing the parts they get tempered at least 110°C inside a convection-oven and cooled down slowly.
The proper tempering time depends strongly on the volume of the built object -  it has to be heated thoroughly.

The 4th dimension shows itself while crystallizing the material, which triggers the structural change of the material. Thus a thermal resistance of 200 °C (constant load) or 230 °C (peak) is reached.

If crystallization is spared, the print result is extremely impact resistant and can take huge mechanical loads. Temperature resistance is located at 80°C in this case. is a division of Bernhardt Kunststoffverarbeitungs GmbH, which has produced foils, plastic parts, and specialized materials for over 50 years now. The company produces in Germany and is highly experienced in installation engineering and developing and processing synthetic materials. Partnerships exist with Fraunhofer Institute and the University of Rostock. The filament processers from Berlin expand the filament unit since 2013 in their HQ in Berlin Heiligensee.

The premium filaments >>made in germany<< are easy to process, due to their special compounding of raw materials and their high consistency. offers biological degradable PLA-filament in every custom and 100 standard colors, flexible bio filament (WillowFlex), specialized materials and their new material >>k-top<<. The technical synthetic is made from food safe raw materials - just like every filament in 3dk´s range. >>k-top>> is offered in black, gray and white and is available in 1.75 and 2.85 millimeters in diameter. One spool of 300g costs 29,90€ including tax and can be ordered directly at or at qualified specialty stores.
