When starting to build 3D printers the general thought processes was, build it cheap. In turn parts were cheap, they worked. Fast forward a few years and finally buying better components, my original thought process couldn’t have been more wrong! For example the E3D($32.99)Copper Heater Block. One of the most noticeable advancements, compared to cheap Chinese heater blocks is stringing from the extruded filament rarely sticks to the heater block itself providing easier cleanup and a more aesthetic appearance. After all hours, days, and weeks have been dedicated to building this 3D printer. It should look pretty!
These blocks are engineered for ultimate high temperature performance. Made from a special high temperature copper-alloy with a softening point of well above 500C (compared to aluminium blocks which begin to lose integrity beyond 350C), and much-increased thermal conductivity these copper blocks are perfect for high temperature applications while working perfectly with everyday filaments like PLA, ABS and spoolWorks EDGE.
In addition to high temperature performance these blocks have an advanced nickel based plating, this plating considerably reduces the adhesion of plastic to the block. This is great for everyday filaments keeping things clean and shiny, but is particularly important at temperatures above 300C where a silicone sock can’t be used.
