Description
The internal and external thermal properties exceed those of the standard block. The heater and temp sensor have better contact with the block. The mass is lower. The Hardcore PVA BB is a drop-in replacement for the standard print Core BB. We add 12 month guarantee*. Hardcore PVA BB ships with tools for nozzle change and 3 nozzles. 3 x 0.40mm Coated Brass + “ICE” (non-sticky surface)
Optional extras:
Various nozzles sizes. There is no 0.25mm nozzle for PVA BB, you can use an 0.25 nozzle for the Hardcore (AA), but it will sometimes drip a little unless you very carefully tune the temperature. Extra Hardcore PVA BB Nozzle kits: 1/4 x 0.40mm for PVA BB Coated Brass “ICE” (non-sticky surface) 1/4 x 0.60mm for PVA BB Coated Brass
Additional information
All nozzles are brass with a hard layer. Each nozzle is a tiny little masterpiece and of a uniquely high build quality (AA: not 0.50 mm SS which is a standard nozzle). We are pressing the prices down to a reasonable level, you and your printer deserve it! Warning: The nozzles will not fit any other block. The HardCore can only use these nozzles. Mixing other nozzles/ blocks will destroy both block and nozzle. Guarantee does not cover destroyed Block / nozzle due to threading failure. You can use the HardCore Pro nozzles on this PVA BB HardCore. * Guarantee: The Core is classified as a consumable. This means that much like tires on a car it wears out quickly or slowly depending on use. However; we introduce a limited guarantee for our HardCore customers. If you cannot yourself resolve HardCore problems you pay shipping to us + 49E, we fix ANY HardCore problems. While at it, we install a new PTFE and tracked return shipping. How can you loose?
