The Hard Core PVA BB is easily recognizable, since the aluminium cooler is now red and the block has a multilayer metal and final chrome finish. 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 Hard Core PVA BB is a drop-in replacement for the standard Print Core BB. Some uncritical parts are re-used.
We add 12 month guarantee* (after testing and verifying every heater and temp sensor). When out of specification, we replace them.
Hard Core PVA BB ships with tools for nozzle change and 3 nozzles.
0.40mm x 2
0.60mm x 1
Various nozzles sizes.
There is no 0.25mm nozzle for PVA BB, you can use an 0.25 nozzle for the Hard Core PRO (AA), but it will sometimes drip a little unless you very carefully tune the temperature.
Extra HardCore PVA BB Nozzle kits:
4 x 0.40mm for PVA BB(70E)
4 x 0.60mm for PVA BB(70E)
All parts are chrome hardened.
Each nozzle is a tiny little masterpiece and of a uniquely high build quality ( 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 Hard Core 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.
* 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 Hard Core customers. Since we carefully verify every Hard Core and re-used part we offer the following guarantee: If you cannot yourself resolve Hard Core problems you pay shipping to us + 39E, we fix ANY Hard Core problems. While at it, we install a new PTFE , a new 0.40 nozzle and tracked return shipping. How can you loose?
The following part with 2 additional nozzles (total 3) comes with a 12 month guarantee*.
